The Single Minute Exchange of Die (SMED) is one of many methods to reduce waste in stamping industry. The Japanese Quick Die Change (QDC) dies system is one of SMED systems that could reduce both of setup time and manufacturing cost. However, this system is rarely used in stamping industries. This paper will analyze how deep the QDC dies system could reduce setup time and the manufacturing cost. The research is conducted by direct observation, simulating and comparing of QDC dies system with conventional dies system. In this research, we found that the QDC dies system could save up to 35% of manufacturing cost and reduce 70% of setup times. This simulation proved that the QDC die system is effective for cost reduction but must be applied in several parallel production processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=press%20die" title="press die">press die</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20stamping" title=" metal stamping"> metal stamping</a>, <a href="https://publications.waset.org/abstracts/search?q=QDC%20system" title=" QDC system"> QDC system</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20minute%20exchange%20die" title=" single minute exchange die"> single minute exchange die</a>, <a href="https://publications.waset.org/abstracts/search?q=manufacturing%20cost%20saving" title=" manufacturing cost saving"> manufacturing cost saving</a>, <a href="https://publications.waset.org/abstracts/search?q=SMED" title=" SMED"> SMED</a> </p> <a href="https://publications.waset.org/abstracts/86870/time-and-cost-efficiency-analysis-of-quick-die-change-system-on-metal-stamping-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86870.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">170</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Synthesis of Bimetallic Fe/Cu Nanoparticles with Different Copper Loading Ratios</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=May%20Thant%20Zin">May Thant Zin</a>, <a href="https://publications.waset.org/abstracts/search?q=Josephine%20Borja"> Josephine Borja</a>, <a href="https://publications.waset.org/abstracts/search?q=Hirofumi%20Hinode"> Hirofumi Hinode</a>, <a href="https://publications.waset.org/abstracts/search?q=Winarto%20Kurniawan"> Winarto Kurniawan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nanotechnology has multiple and enormous advantages for all application. Therefore, this research is carried out to synthesize and characterize bimetallic iron with copper nano-particles. After synthesizing nano zero valent iron by reduction of ferric chloride by sodium borohydride under nitrogen purging environment, bimetallic iron with copper nanoparticles are synthesized by varying different loads of copper chloride. Due to different standard potential (E0) values of copper and iron, copper is coupled with iron at (Cu to Fe ratio of 1:5, 1:6.7, 1:10, 1:20). It is found that the resulted bimetallic Fe/Cu nanoparticles are composing phases of iron and copper. According to the diffraction patterns indicating the state of chemical combination of the bimetallic nanoparticles, the particles are well-combined and crystalline sizes are less than 1000 Ao (or 100 nm). Specifically, particle sizes of synthesized bimetallic Fe/Cu nanoparticles are ranging from 44.583 nm to 85.149 nm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=" title=""></a> </p> <a href="https://publications.waset.org/abstracts/3276/synthesis-of-bimetallic-fecu-nanoparticles-with-different-copper-loading-ratios" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3276.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">444</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">44</span> Using Phase Equilibrium Theory to Calculate Solubility of γ-Oryzanol in Supercritical CO2</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Boy%20Arief%20Fachri">Boy Arief Fachri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Even its content is rich in antioxidants &upsih;-oryzanol, rice bran is not used properly as functional food. This research aims to (1) extract &upsih;-oryzanol; (2) determine the solubility of &upsih;-oryzanol in supercritical CO<sub>2</sub> based on phase equilibrium theory; and (3) study the effect of process variables on solubility. Extraction experiments were carried out for rice bran (5 g) at various extraction pressures, temperatures and reaction times. The flowrate of supercritical fluid through the extraction vessel was 25 g/min. The extracts were collected and analysed with high-pressure liquid chromatography (HPLC). The conclusion based on the experiments are as: (1) The highest experimental solubility was 0.303 mcg/mL RBO at T= 60°C, P= 90 atm, t= 30 min; (2) Solubility of &upsih;-oryzanol was influenced by pressure and temperature. As the pressure and temperature increase, the solubility increases; (3) The solubility data of supercritical extraction can be successfully determined using phase equilibrium theory.

The first is to examine the position of SDP within the context of software quality, and the second is to reframe the aspects of SDP into a more concise terms and relations. This paper is divided into four parts, in which after the introduction, a review on related software quality is provided to determine the quality context of SDP. The third part reviews the original SDP and offers a relation model among the SDP aspects. The fourth part explores the design quality metrics available for SOA and proposes a relationship representing the design quality. Among the aspects of design principles, the cohesion and coupling aspect is determined to be the two important aspects for achieving reusability of a service. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SOA" title="SOA">SOA</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20quality" title=" software quality"> software quality</a>, <a href="https://publications.waset.org/abstracts/search?q=service%20design%20principle" title=" service design principle"> service design principle</a>, <a href="https://publications.waset.org/abstracts/search?q=reusability" title=" reusability"> reusability</a>, <a href="https://publications.waset.org/abstracts/search?q=cohesion" title=" cohesion"> cohesion</a>, <a href="https://publications.waset.org/abstracts/search?q=coupling" title=" coupling"> coupling</a> </p> <a href="https://publications.waset.org/abstracts/107939/reframing-service-oriented-architecture-design-principles-in-software-design-quality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107939.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">171</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Analysis of Universal Mobile Telecommunications Service (UMTS) Planning Using High Altitude Platform Station (HAPS)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yosika%20Dian%20Komala">Yosika Dian Komala</a>, <a href="https://publications.waset.org/abstracts/search?q=Uke%20Kurniawan%20Usman"> Uke Kurniawan Usman</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuyun%20Siti%20Rohmah"> Yuyun Siti Rohmah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The enable technology fills up needs of high-speed data service is Universal Mobile Telecommunications Service (UMTS).

This research was conducted from September to December 2011 in the Raharja and Cinanjung Village, Tanjungsari, Sumedang District, West Java, Indonesia. The study was carried out using physiographic free survey method, which is a survey based on land physiographic appearance. Soil sampling was carried out into transect on the similarity slope without calculating the point of observation range. Soil sampling was carried onto three classes of slope as follows: 8–15%, 15–25% and 25–40%. Each was consisted of three slope position i.e. top slope, middle slope and down slope and four samples of soil were taken from each of them, hence it resulted in 36 points of observation. The results of this study indicate that gradient of slope have some significant contribution in every sample. Middle slope with gradient 26-40% has the highest potential erosion occurrence. It has organic C content (0.84%) and the highest erodibility value (0.1092). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=slope%20steepness" title="slope steepness">slope steepness</a>, <a href="https://publications.waset.org/abstracts/search?q=erosion" title=" erosion"> erosion</a>, <a href="https://publications.waset.org/abstracts/search?q=erodibility" title=" erodibility"> erodibility</a>, <a href="https://publications.waset.org/abstracts/search?q=erosion%20factor" title=" erosion factor"> erosion factor</a> </p> <a href="https://publications.waset.org/abstracts/9258/effect-of-slope-steepness-with-toposequent-on-erosion-factor-a-study-case-of-cikeruh-catchment-area-west-java-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9258.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">403</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> Simultaneous Esterification and Transesterification of High FFA Jatropha Oil Using Reactive Distillation for Biodiesel Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ratna%20Dewi%20Kusumaningtyas">Ratna Dewi Kusumaningtyas</a>, <a href="https://publications.waset.org/abstracts/search?q=Prima%20Astuti%20Handayani"> Prima Astuti Handayani</a>, <a href="https://publications.waset.org/abstracts/search?q=Arief%20Budiman"> Arief Budiman </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reactive Distillation (RD) is a multifunctional reactor which integrates chemical reaction with in situ separation to shift the equilibrium towards the product formation. Thus, it is suitable for equilibrium limited reaction such as esterification and transesterification to enhance the reaction conversion. In this work, the application of RD for high FFA oil esterification-transterification for biodiesel production using sulphuric acid catalyst has been studied. Crude Jatropha Oil with FFA content of 30.57% was utilized as the feedstock. Effects of the catalyst concentration and molar ratio of the alcohol to oils were also investigated. It was revealed that best result was obtained with sulphuric acid catalyst (reaction conversion of 94.71% and FFA content of 1.62%) at 60C, molar ratio of methanol to FFA of 30:1, and catalyst loading of 3%. After undergoing esterification reaction, jatropha oil was then transesterified to produce biodiesel.

The forecasts influence final decision-making processes in multiple areas, from agriculture and prevention of natural disasters to air traffic regulations and solutions on a national level for health, security, and economic problems. Namely, in Slovenia, alongside other existing forms of application, weather forecasts are adopted for the prognosis of electrical current transmission through powerlines. Meteorological parameters are one of the key factors which need to be considered in estimations of the reliable supply of electrical energy to consumers. And like for any other measured value, the knowledge about measurement uncertainty is also critical for the secure and reliable supply of energy. The estimation of measurement uncertainty grants us a more accurate interpretation of data, a better quality of the end results, and even a possibility of improvement of weather forecast models. In the article, we focused on the estimation of measurement uncertainty of the diagnostic microscale meteorological model CALMET. For the purposes of our research, we used a network of meteorological stations spread in the area of our interest, which enables a side-by-side comparison of measured meteorological values with the values calculated with the help of CALMET and the measurement uncertainty estimation as a final result. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=uncertancy" title="uncertancy">uncertancy</a>, <a href="https://publications.waset.org/abstracts/search?q=meteorological%20model" title=" meteorological model"> meteorological model</a>, <a href="https://publications.waset.org/abstracts/search?q=meteorological%20measurment" title=" meteorological measurment"> meteorological measurment</a>, <a href="https://publications.waset.org/abstracts/search?q=CALMET" title=" CALMET"> CALMET</a> </p> <a href="https://publications.waset.org/abstracts/171084/determination-of-measurement-uncertainty-of-the-diagnostic-meteorological-model-calmet" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171084.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">81</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> Pyrolysis of Mixed Plastic Fractions with PP, PET and PA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rudi%20P.%20Nielsen">Rudi P.

Plastic fractions were pyrolyzed in a lab-scale reactor system, with mixture compositions of up to 15 wt.% PET and five wt.% PA in a PP matrix and processing conditions from 400 to 450°C. The experiments were conducted as a full factorial design and in duplicates to provide reliable results and the possibility to determine any interactions between the parameters. The products were analyzed using FT-IR and GC-MS for compositional information as well as the determination of calorific value, ash content, acid number, density, viscosity, and elemental analysis to provide further data on the fuel quality of the pyrolysis oil. Oil yield was found to be between 61 and 84 wt.%, while char yield was below 2.6 wt.% in all cases. The calorific value of the produced oil was between 32 and 46 MJ/kg, averaging at approx. 41 MJ/kg, thus close to that of heavy fuel oil. The oil product was characterized to contain aliphatic and cyclic hydrocarbons, alcohols, and ethers with chain lengths between 10 and 25 carbon atoms. Overall, it was found that the addition of PET decreased oil yield, while the addition of both PA and PET decreased oil quality in general by increasing acid number (PET), decreasing calorific value (PA), and increasing nitrogen content (PA). Furthermore, it was identified that temperature increased ammonia production from PA during pyrolysis, while ammonia production was decreased by the addition of PET. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PET" title="PET">PET</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20waste" title=" plastic waste"> plastic waste</a>, <a href="https://publications.waset.org/abstracts/search?q=polyamide" title=" polyamide"> polyamide</a>, <a href="https://publications.waset.org/abstracts/search?q=polypropylene" title=" polypropylene"> polypropylene</a>, <a href="https://publications.waset.org/abstracts/search?q=pyrolysis" title=" pyrolysis"> pyrolysis</a> </p> <a href="https://publications.waset.org/abstracts/129430/pyrolysis-of-mixed-plastic-fractions-with-pp-pet-and-pa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129430.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">148</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Integrating Eye-Tracking Analysis to Enhance Web Usability Evaluation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Johanna%20Renny%20Octavia">Johanna Renny Octavia</a>, <a href="https://publications.waset.org/abstracts/search?q=Meliana%20Nurdin"> Meliana Nurdin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ignatius%20Kevin%20Kurniawan"> Ignatius Kevin Kurniawan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ricca%20Aksara"> Ricca Aksara</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is widely believed that usability evaluation is necessary to evaluate a website design for further improvement. Traditional methods of usability evaluation have given sufficient insights to reveal usability problems of websites. Eye-tracking analysis has been considered as a useful method that adds a powerful dimension to web usability evaluation. It allows web designers and usability researchers to understand exactly what users do and do not see on a web page, thus disclose more information on web usability and provide a more complete insights on a website design. This paper elaborates on moving beyond traditional methods of web usability evaluation by integrating eye-tracking analysis to enhance the evaluation of website design, and presents three case studies to support this approach. In these case studies, eye movement metrics such as gaze plots and fixation-derived metrics, and user performance data such as task completion times and number of errors were recorded as objective measurements that can inform the necessity for website design improvements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design" title="design">design</a>, <a href="https://publications.waset.org/abstracts/search?q=eye-tracking" title=" eye-tracking"> eye-tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=usability%20evaluation" title=" usability evaluation"> usability evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=website" title=" website"> website</a> </p> <a href="https://publications.waset.org/abstracts/54471/integrating-eye-tracking-analysis-to-enhance-web-usability-evaluation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54471.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">303</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Consolidating Service Engineering Ontologies Building Service Ontology from SOA Modeling Language (SoaML)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Purnomo%20Yustianto">Purnomo Yustianto</a>, <a href="https://publications.waset.org/abstracts/search?q=Robin%20Doss"> Robin Doss</a>, <a href="https://publications.waset.org/abstracts/search?q=Suhardi"> Suhardi</a>, <a href="https://publications.waset.org/abstracts/search?q=Novianto%20Budi%20Kurniawan"> Novianto Budi Kurniawan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As a term for characterizing a process of devising a service system, the term ‘service engineering’ is still regarded as an ‘open’ research challenge due to unspecified details and conflicting perspectives. This paper presents consolidated service engineering ontologies in collecting, specifying and defining relationship between components pertinent within the context of service engineering. The ontologies are built by way of literature surveys from the collected conceptual works by collating various concepts into an integrated ontology. Two ontologies are produced: general service ontology and software service ontology. The software-service ontology is drawn from the informatics domain, while the generalized ontology of a service system is built from both a business management and the information system perspective. The produced ontologies are verified by exercising conceptual operationalizations of the ontologies in adopting several service orientation features and service system patterns. The proposed ontologies are demonstrated to be sufficient to serve as a basis for a service engineering framework. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=engineering" title="engineering">engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=ontology" title=" ontology"> ontology</a>, <a href="https://publications.waset.org/abstracts/search?q=service" title=" service"> service</a>, <a href="https://publications.waset.org/abstracts/search?q=SoaML" title=" SoaML"> SoaML</a> </p> <a href="https://publications.waset.org/abstracts/98182/consolidating-service-engineering-ontologies-building-service-ontology-from-soa-modeling-language-soaml" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98182.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">188</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> The Quality of Food and Drink Product Labels Translation from Indonesian into English</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rudi%20Hartono">Rudi Hartono</a>, <a href="https://publications.waset.org/abstracts/search?q=Bambang%20Purwanto"> Bambang Purwanto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The translation quality of food and drink labels from Indonesian into English is poor because the translation is not accurate, less natural, and difficult to read. The label translation can be found in some cans packages of food and drink products produced and marketed by several companies in Indonesia.

This study was conducted to analyze the translation errors on food and drink products labels and formulate the solution for the better translation quality. The research design was the evaluation research with a holistic criticism approach. The data used were words, phrases, and sentences translated from Indonesian to English language printed on food and drink product labels. The data were processed by using Interactive Model Analysis that carried out three main steps: collecting, classifying, and verifying data. Furthermore, the data were analyzed by using content analysis to view the accuracy, naturalness, and readability of translation. The results showed that the translation quality of food and drink product labels from Indonesian to English has the level of accuracy (60%), level of naturalness (50%), and level readability (60%).

The ceramics industry includes one of seven industries categorized as an energy-intensive industry. Energy costs on the ceramic floor production process reached 40 percent of the total production cost. The kiln is one of the machines in the ceramic industry that consumes the most gas energy reach 51 percent of gas consumption in ceramic production. The purpose of this research is to make improvement of energy consumption in kiln machine part with the innovation of burner tube to support the sustainability of Indonesian ceramics industry. The tube burner is technically designed to be able to raise the temperature and stabilize the air pressure in the burner so as to facilitate the combustion process in the kiln machine which implies the efficiency of gas consumption required. The innovation of the burner tube also has an impact on the decrease of the combustion chamber pressure in the kiln and managed to keep the pressure of the combustion chamber according to the operational standard of the kiln; consequently, the smoke fan motor power can be lowered and the kiln electric energy consumption is also more efficient. The innovation of burner tube succeeded in saving consume of gas and electricity respectively by 0.0654 GJ and 1,693 x 10-3 GJ for every ton of ceramics produced. Improvement of this energy consumption not only implies the cost savings of production but also supports the sustainability of the Indonesian ceramics industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainable%20ceramic%20industry" title="sustainable ceramic industry">sustainable ceramic industry</a>, <a href="https://publications.waset.org/abstracts/search?q=burner%20tube" title=" burner tube"> burner tube</a>, <a href="https://publications.waset.org/abstracts/search?q=kiln" title=" kiln"> kiln</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title=" energy efficiency"> energy efficiency</a> </p> <a href="https://publications.waset.org/abstracts/89941/improvement-of-energy-consumption-toward-sustainable-ceramic-industry-in-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89941.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">324</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> Design and Implementation of Pseudorandom Number Generator Using Android Sensors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mochamad%20Beta%20Auditama">Mochamad Beta Auditama</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Kurniawan"> Yusuf Kurniawan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A smartphone or tablet require a strong randomness to establish secure encrypted communication, encrypt files, etc. Therefore, random number generation is one of the main keys to provide secrecy. Android devices are equipped with hardware-based sensors, such as accelerometer, gyroscope, etc. Each of these sensors provides a stochastic process which has a potential to be used as an extra randomness source, in addition to /dev/random and /dev/urandom pseudorandom number generators. Android sensors can provide randomness automatically. To obtain randomness from Android sensors, each one of Android sensors shall be used to construct an entropy source. After all entropy sources are constructed, output from these entropy sources are combined to provide more entropy. Then, a deterministic process is used to produces a sequence of random bits from the combined output. All of these processes are done in accordance with NIST SP 800-22 and the series of NIST SP 800-90.

The existence of S-Box in the cryptographic algorithm is needed to maintain non-linearity of the algorithm. Nowadays, modern cryptographic algorithms use an S-Box as a part of algorithm process. Despite the fact that several cryptographic algorithms today reuse theoretically secure and carefully constructed S-Boxes, there is an evaluation characteristic that can measure security properties of S-Boxes and hence the corresponding primitives. Analysis of an S-Box usually is done using manual mathematics calculation. Several S-Boxes are presented as a Truth Table without any mathematical background algorithm. Then, it’s rather difficult to determine the strength of Truth Table S-Box without a mathematical algorithm. A comprehensive analysis should be applied to the Truth Table S-Box to determine the characteristic. Several important characteristics should be owned by the S-Boxes, they are Nonlinearity, Balancedness, Algebraic degree, LAT, DAT, differential delta uniformity, correlation immunity and global avalanche criterion. Then, a comprehensive tool will be present to automatically calculate the characteristics of S-Boxes and determine the strength of S-Box. Comprehensive analysis is done on a deterministic process to produce a sequence of S-Boxes characteristic and give advice for a better S-Box construction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryptographic%20properties" title="cryptographic properties">cryptographic properties</a>, <a href="https://publications.waset.org/abstracts/search?q=Truth%20Table%20S-Boxes" title=" Truth Table S-Boxes"> Truth Table S-Boxes</a>, <a href="https://publications.waset.org/abstracts/search?q=S-Boxes%20characteristic" title=" S-Boxes characteristic"> S-Boxes characteristic</a>, <a href="https://publications.waset.org/abstracts/search?q=deterministic%20process" title=" deterministic process"> deterministic process</a> </p> <a href="https://publications.waset.org/abstracts/65017/classifying-and-analysis-8-bit-to-8-bit-s-boxes-characteristic-using-s-box-evaluation-characteristic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65017.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">363</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Effect of Addition of Surfactant to the Surface Hydrophilicity and Photocatalytic Activity of Immobilized Nano TiO2 Thin Films </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eden%20G.%20Mariquit">Eden G.

The prepared films were characterized using FE-SEM, TG-DTA, and XRD, and its photocatalytic performances were tested on degradation of an organic dye, methylene blue. Aside from its phocatalytic performance, the photo-induced hydrophilicity of thin TiO2 films surface was also studied. Characterization results showed that the addition of surfactant gave rise to characteristic patterns on the surface of the TiO2 thin film which also affects the photocatalytic activity. The addition of CTAB to the TiO2 dipping solution had a negative effect because the calcination temperature was not high enough to burn all the surfactants off.

This also includes the positive impact of CSR on the commitment of its employees. The internal CSR communication here takes the essential function as a mediator of the CSR performance of a company to the employees. The importance of CSR communication is, therefore, essential. Employees can usually only perceive the CSR efforts of a company if it is also communicated to them. Only if the employees perceive the CSR of their employer positively, the employer-CSR can also have a positive impact on their affective commitment. Therefore, organizational and individual factors are crucial and thus need to consider. This relationship between the organizational and individual factors was investigated in a qualitative case study in six companies of the German service sector. Expert interviews and focus group interviews were conducted and questionnaire-based ratings by company representatives were raised. Among the individual factors, in terms of CSR, the expectations and relevance of its employees, as well as the perception of CSR by the staff, are included. The organizational factors include the actual CSR performance and its communication. Ultimately, the impact of CSR on the commitment is examined with this holistic approach. The results show that the individual CSR perception does not always match the corporate CSR performance and its depiction in internal communication. Furthermore, employees have given suggestions on how CSR should be communicated by their employer. Knowledge memory systems (e.g. wiki) on the on hand and media-based information, on the other hand, were highlighted. Primarily the employee-related CSR is most important for the employees, whereas ecological CSR activities hardly play a role. The findings indicate the importance of CSR communication in the CSR concept as it provides the missing link between CSR performance and appreciation by an increase in commitment. It should only be communicated, what is done. CSR communication should also be carried out in a plausible and transparent way. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CSR" title="CSR">CSR</a>, <a href="https://publications.waset.org/abstracts/search?q=employee%20commitment" title=" employee commitment"> employee commitment</a>, <a href="https://publications.waset.org/abstracts/search?q=employer%20brand" title=" employer brand"> employer brand</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20communication" title=" internal communication"> internal communication</a> </p> <a href="https://publications.waset.org/abstracts/46336/csr-and-its-internal-communication-effects-on-the-employee-commitment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46336.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">265</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Compilation of Islamic Law as Law Applied Religious Courts in Indonesia (Responding to Changes in Religious Courts Authority)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamdan%20Arief%20Hanif">Hamdan Arief Hanif</a>, <a href="https://publications.waset.org/abstracts/search?q=Rahmat%20Sidiq"> Rahmat Sidiq</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Indonesia is a country of law, the legal system adopted by Indonesia is a civil law system. A major feature of the civil law is the codified legislation. Meanwhile the majority of society Indonesia are Muslims, whilst Islamic law itself having the sources written in Qur'an, Sunnah and the opinion of Muslim scholars, generally not codified in book form of legislation that is easy on the set as a reference. in Indonesia, many scholars have different opinions in decisions so that there is no legal certainty in Muslim civil cases, so the need for legal codification, which, as the source of the judges in deciding a case, especially a case in religious courts. This paper raised the topic of discussion which offers a solution to the application of the codification of the Islamic Law which became the core resources in delivering a verdict against Islamic civil related issue; codification usually called a compilation of Islamic Law. Compilation of Islamic Law is highly recommended as a core reference for the judges in religious courts in Indonesia. This compilation which includes a collection of large number of opinions scholars (book of fiqh) that existed previously and are ripened in deduce in order to unify the existing differences. This paper also discusses how the early formation of the compilation and as the right solution in order to create legal certainty and justice especially for the muslim community in Indonesia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Islamic%20law" title="Islamic law">Islamic law</a>, <a href="https://publications.waset.org/abstracts/search?q=compilation" title=" compilation"> compilation</a>, <a href="https://publications.waset.org/abstracts/search?q=law%20applied%20core" title=" law applied core"> law applied core</a>, <a href="https://publications.waset.org/abstracts/search?q=religious%20court" title=" religious court"> religious court</a> </p> <a href="https://publications.waset.org/abstracts/62785/compilation-of-islamic-law-as-law-applied-religious-courts-in-indonesia-responding-to-changes-in-religious-courts-authority" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62785.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">355</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Security Report Profiling for Mobile Banking Applications in Indonesia Based on OWASP Mobile Top 10-2016</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bambang%20Novianto">Bambang Novianto</a>, <a href="https://publications.waset.org/abstracts/search?q=Rizal%20Aditya%20Herdianto"> Rizal Aditya Herdianto</a>, <a href="https://publications.waset.org/abstracts/search?q=Raphael%20Bianco%20Huwae"> Raphael Bianco Huwae</a>, <a href="https://publications.waset.org/abstracts/search?q=Afifah"> Afifah</a>, <a href="https://publications.waset.org/abstracts/search?q=Alfonso%20Brolin%20%20Sihite"> Alfonso Brolin Sihite</a>, <a href="https://publications.waset.org/abstracts/search?q=Rudi%20Lumanto"> Rudi Lumanto </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The mobile banking application is a type of mobile application that is growing rapidly. This is caused by the ease of service and time savings in making transactions. On the other hand, this certainly provides a challenge in security issues. The use of mobile banking can not be separated from cyberattacks that may occur which can result the theft of sensitive information or financial loss. The financial loss and the theft of sensitive information is the most avoided thing because besides harming the user, it can also cause a loss of customer trust in a bank. Cyberattacks that are often carried out against mobile applications are phishing, hacking, theft, misuse of data, etc. Cyberattack can occur when a vulnerability is successfully exploited. OWASP mobile Top 10 has recorded as many as 10 vulnerabilities that are most commonly found in mobile applications. In the others, android permissions also have the potential to cause vulnerabilities. Therefore, an overview of the profile of the mobile banking application becomes an urgency that needs to be known. So that it is expected to be a consideration of the parties involved for improving security. In this study, an experiment has been conducted to capture the profile of the mobile banking applications in Indonesia based on android permission and OWASP mobile top 10 2016. The results show that there are six basic vulnerabilities based on OWASP Mobile Top 10 that are most commonly found in mobile banking applications in Indonesia, i.e. M1:Improper Platform Usage, M2:Insecure Data Storage, M3:Insecure Communication, M5:Insufficient Cryptography, M7:Client Code Quality, and M9:Reverse Engineering. The most permitted android permissions are the internet, status network access, and telephone read status. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mobile%20banking%20application" title="mobile banking application">mobile banking application</a>, <a href="https://publications.waset.org/abstracts/search?q=OWASP%20mobile%20top%2010%202016" title=" OWASP mobile top 10 2016"> OWASP mobile top 10 2016</a>, <a href="https://publications.waset.org/abstracts/search?q=android%20permission" title=" android permission"> android permission</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitive%20information" title=" sensitive information"> sensitive information</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20loss" title=" financial loss"> financial loss</a> </p> <a href="https://publications.waset.org/abstracts/118937/security-report-profiling-for-mobile-banking-applications-in-indonesia-based-on-owasp-mobile-top-10-2016" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118937.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">141</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> CSR and Employer Attractiveness: The Relationship of Value Orientation of High-Potential Applicants and Their Decision for an Employer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Silke%20Bustamante">Silke Bustamante</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Pelzeter"> Andrea Pelzeter</a>, <a href="https://publications.waset.org/abstracts/search?q=Andreas%20Deckmann"> Andreas Deckmann</a>, <a href="https://publications.waset.org/abstracts/search?q=Rudi%20Ehlscheidt"> Rudi Ehlscheidt</a>, <a href="https://publications.waset.org/abstracts/search?q=Franziska%20Freudenberger"> Franziska Freudenberger</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Against the background of demographic changes and the need for motivated and talented employees, companies have a growing interest in being perceived as an attractive employer and gain a competitive edge in the market for talents. Research indicates that corporate social responsibility plays an important role employer choice. This is assumed to be particularly true for the cohorts of the so-called generations y younger applicants born later. Several studies identified cultural, educational and generational differences in CSR preferences. However, until now literature that links preferences for employers’ responsibility with the individual value orientation of the job applicant is scarce. This paper seeks to close this gap and analyzes the preference structure of 500 German university graduates for CSR-related and non-CSR-related employer attributes contingent on their value orientation. In a first step, we identified 17 CSR related attributes in five CSR dimensions (ecology, community, workplace, governance, and market) as well as 11 traditional attributes such as salary, reputation, personal development etc. based on literature review and focus groups. We then used an adapted Conjoint Analysis framework in order to understand the relative preference of each attribute for each participant. Additionally, we surveyed the value orientation of participants based on the European Social Survey (ESS) 21-item human values scale that allow a differentiation of participants into clusters of value orientation. The results allow us not only to operationalize preferences for CSR and other important employer attributes, but – more importantly – to answer the question how different values structures play together with CSR preferences of potential employees. They hereby allow companies to customize employee directed messages to their respective target group and design their employer brand accordingly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corporate%20social%20responsibility" title="corporate social responsibility">corporate social responsibility</a>, <a href="https://publications.waset.org/abstracts/search?q=employer%20attractiveness" title=" employer attractiveness"> employer attractiveness</a>, <a href="https://publications.waset.org/abstracts/search?q=employer%20brand" title=" employer brand"> employer brand</a>, <a href="https://publications.waset.org/abstracts/search?q=recruiting" title=" recruiting"> recruiting</a>, <a href="https://publications.waset.org/abstracts/search?q=values" title=" values"> values</a> </p> <a href="https://publications.waset.org/abstracts/46339/csr-and-employer-attractiveness-the-relationship-of-value-orientation-of-high-potential-applicants-and-their-decision-for-an-employer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46339.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">287</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Epidemiological Survey on Tick-Borne Pathogens with Zoonotic Potential in Dog Populations of Southern Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hana%20Tadesse">Hana Tadesse</a>, <a href="https://publications.waset.org/abstracts/search?q=Marika%20Grillini"> Marika Grillini</a>, <a href="https://publications.waset.org/abstracts/search?q=Giulia%20Simonato"> Giulia Simonato</a>, <a href="https://publications.waset.org/abstracts/search?q=Alessandra%20Mondin"> Alessandra Mondin</a>, <a href="https://publications.waset.org/abstracts/search?q=Giorgia%20Dotto"> Giorgia Dotto</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Frangipane%20Di%20Regalbono"> Antonio Frangipane Di Regalbono</a>, <a href="https://publications.waset.org/abstracts/search?q=Bersissa%20Kumsa"> Bersissa Kumsa</a>, <a href="https://publications.waset.org/abstracts/search?q=Rudi%20Cassini"> Rudi Cassini</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Luisa%20Menandro"> Maria Luisa Menandro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dogs are known to host several tick-borne pathogens with zoonotic potential; however, scant information is available on the epidemiology of these pathogens in low-income tropical coun- tries and in particular in sub-Saharan Africa. With the aim of investigating a wide range of tick- borne pathogens (i.e., Rickettsia spp., Anaplasma spp., Erhlichia spp., Borrelia spp., Hepatozoon spp. and Babesia spp.), 273 blood samples were collected from dogs in selected districts of Ethiopia and analyzed by real-time and/or end-point PCR. The results of the study showed that Hepatozoon canis was the most prevalent pathogen (53.8%), followed by Anaplasma phagocythophilum (7.0%), Babesia canis rossi (3.3%), Ehrlichia canis (2.6%) and Anaplasma platys (2.2%). Furthermore, five samples tested positive for Borrelia spp., identified as Borrelia afzelii (n = 3) and Borrelia burgdorferi (n = 2), and two samples for Rickettsia spp., identified as Rickettsia conorii (n = 1) and Rickettsia monacensis (n = 1). The finding of Anaplasma phagocythophilum and different species of the genera Borrelia and Rickettsia with zoonotic potential was unexpected and alarming, and calls for further investigation on the roles of dogs and on the tick, species acting as vector in this specific context. Other pathogens (Hepatozoon canis, Babaesia canis rossi, Anaplasma platys, Ehrlichia canis) are already known to have an important impact on the dogs’ health but have minor zoonotic potential as they were rarely or never reported in humans. Dogs from rural areas were found to be at higher risk for different pathogens, probably due to the presence of other wild canids in the same environment. The findings of the present study contribute to a better knowledge of the epidemiology of tick-borne pathogens, which is relevant to human and animal health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dogs" title="Dogs">Dogs</a>, <a href="https://publications.waset.org/abstracts/search?q=Tick-borne%20pathogens" title=" Tick-borne pathogens"> Tick-borne pathogens</a>, <a href="https://publications.waset.org/abstracts/search?q=Africa" title=" Africa"> Africa</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopia" title=" Ethiopia"> Ethiopia</a> </p> <a href="https://publications.waset.org/abstracts/163030/epidemiological-survey-on-tick-borne-pathogens-with-zoonotic-potential-in-dog-populations-of-southern-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163030.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">92</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Legal Interpretation of the Transplanted Law</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wahyu%20Kurniawan">Wahyu Kurniawan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Indonesia developed the legal system radically since 1999. Several laws have been established and mostly the result of transplantation. Laws were made general but legal problems have been growing. In the legal enforcement, the judges have authority to interpret the laws. Authority and freedom are the source of corruption by the courts in Indonesia. Therefore, it should be built the conceptual framework to interpret the transplanted laws as the legal basis in deciding the cases. This article describes legal development based on interpretation of transplanted law in Indonesia by using the Indonesian Supervisory Commission for Business Competition (KPPU) decisions between 2000 and 2010 as the object of the research. The study was using law as a system theory and theories of legal interpretation especially the static and dynamic interpretations. The research showed that the KPPU interpreted the concept that exists in the Competition Law by using static and dynamic interpretation. Static interpretation was used to interpret the legal concepts based on two grounds, minute of meeting during law making process and the definitions that have been recognized in the Indonesian legal system. Dynamic interpretation was used when the KPPU developing the definition of the legal concepts. The general purpose of the law and the theories of the basis of the law were the conceptual framework in using dynamic interpretation. There are two recommendations in this article. Firstly, interpreting the laws by the judges should be based on the correct conceptual framework. Secondly, the technique of interpreting the laws would be the method of controlling the judges. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=legal%20interpretation" title="legal interpretation">legal interpretation</a>, <a href="https://publications.waset.org/abstracts/search?q=legal%20transplant" title=" legal transplant"> legal transplant</a>, <a href="https://publications.waset.org/abstracts/search?q=competition%20law" title=" competition law"> competition law</a>, <a href="https://publications.waset.org/abstracts/search?q=KPPU" title=" KPPU"> KPPU</a> </p> <a href="https://publications.waset.org/abstracts/45342/legal-interpretation-of-the-transplanted-law" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45342.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">341</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Breaking Sensitivity Barriers: Perovskite Based Gas Sensors With Dimethylacetamide-Dimethyl Sulfoxide Solvent Mixture Strategy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Endalamaw%20Ewnu%20Kassa">Endalamaw Ewnu Kassa</a>, <a href="https://publications.waset.org/abstracts/search?q=Ade%20Kurniawan"> Ade Kurniawan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ya-Fen%20Wu"> Ya-Fen Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Sajal%20Biring"> Sajal Biring</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Perovskite-based gas sensors represent a highly promising materials within the realm of gas sensing technology, with a particular focus on detecting ammonia (NH3) due to its potential hazards. Our work conducted thorough comparison of various solvents, including dimethylformamide (DMF), DMF-dimethyl sulfoxide (DMSO), dimethylacetamide (DMAC), and DMAC-DMSO, for the preparation of our perovskite solution (MAPbI3). Significantly, we achieved an exceptional response at 10 ppm of ammonia gas by employing a binary solvent mixture of DMAC-DMSO. In contrast to prior reports that relied on single solvents for MAPbI3 precursor preparation, our approach using mixed solvents demonstrated a marked improvement in gas sensing performance. We attained enhanced surface coverage, a reduction in pinhole occurrences, and precise control over grain size in our perovskite films through the careful selection and mixtures of appropriate solvents. This study shows a promising potential of employing binary and multi-solvent mixture strategies as a means to propel advancements in gas sensor technology, opening up new opportunities for practical applications in environmental monitoring and industrial safety. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sensors" title="sensors">sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=binary%20solvents" title=" binary solvents"> binary solvents</a>, <a href="https://publications.waset.org/abstracts/search?q=ammonia" title=" ammonia"> ammonia</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity" title=" sensitivity"> sensitivity</a>, <a href="https://publications.waset.org/abstracts/search?q=grain%20size" title=" grain size"> grain size</a>, <a href="https://publications.waset.org/abstracts/search?q=pinholes" title=" pinholes"> pinholes</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20coverage" title=" surface coverage"> surface coverage</a> </p> <a href="https://publications.waset.org/abstracts/175863/breaking-sensitivity-barriers-perovskite-based-gas-sensors-with-dimethylacetamide-dimethyl-sulfoxide-solvent-mixture-strategy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175863.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">107</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Neural Network Based Fluctuation Frequency Control in PV-Diesel Hybrid Power System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Heri%20Suryoatmojo">Heri Suryoatmojo</a>, <a href="https://publications.waset.org/abstracts/search?q=Adi%20Kurniawan"> Adi Kurniawan</a>, <a href="https://publications.waset.org/abstracts/search?q=Feby%20A.%20Pamuji"> Feby A.

PV output power fluctuates due to uncertainty condition of temperature and sun irradiance. When the penetration of PV power is large, the reliability of the power utility will be disturbed and seriously impact the unstable frequency of system. Therefore, designing a robust frequency controller in PV-diesel hybrid power system is very important. This paper proposes new method of frequency control application in hybrid PV-diesel system based on artificial neural network (ANN). This method can minimize the frequency deviation without smoothing PV output power that controlled by maximum power point tracking (MPPT) method. The neural network algorithm controller considers average irradiance, change of irradiance and frequency deviation. In order the show the effectiveness of proposed algorithm, the addition of battery as energy storage system is also presented. To validate the proposed method, the results of proposed system are compared with the results of similar system using MPPT only. The simulation results show that the proposed method able to suppress frequency deviation smaller compared to the results of system using MPPT only. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20storage%20system" title="energy storage system">energy storage system</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency%20deviation" title=" frequency deviation"> frequency deviation</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20power%20generation" title=" hybrid power generation"> hybrid power generation</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20network%20algorithm" title=" neural network algorithm"> neural network algorithm</a> </p> <a href="https://publications.waset.org/abstracts/4960/neural-network-based-fluctuation-frequency-control-in-pv-diesel-hybrid-power-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4960.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">502</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> The Utilization of Rain Water to Ground Water with Tube in the Area of Tourism in Yogyakarta</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kurniawan%20Agung%20Pambudi">Kurniawan Agung Pambudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Alfian%20Deo%20Pradipta"> Alfian Deo Pradipta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Yogyakarta is the famous tourism city in Indonesia. The Tugu Jogja is a tourism center located in Jetis. To support the tourism activities required facilities such as tourist hotel and guest house. The existence of tourism also has an impact on the environment. The surface of the land is covered by cement and a local company dealing in ceramics, then an infiltration process is not running. The existence of the building in layers resulting in the amount of water resource in Jetis decreases. The purpose of this research is to know the impact of the construction of the building in layers in Jetis. To obtain the data done by observation, measurements and taking the land profile, along with the interview to people in Jetis. The results of the study showed that the number of water sources in Jetis, Yogyakarta start decreases as a result of the construction of the building on stilts as a result, the height of the surface of the groundwater decreases and digging a pit must be in to get the source of the waters. Based on the results of research it can be concluded that the height of the surface of the groundwater decreases. To resolve the issue required a method to rainwater can seep into the ground for maximum. The rain that fell upon the precarious houses or other buildings is channeled toward the ground through the tubes with the depth of 1-2 meters. Rainwater will be absorbed into the land and increase the amount of ground water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rain%20water" title="rain water">rain water</a>, <a href="https://publications.waset.org/abstracts/search?q=tube" title=" tube"> tube</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20resource" title=" water resource"> water resource</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater" title=" groundwater "> groundwater </a> </p> <a href="https://publications.waset.org/abstracts/48897/the-utilization-of-rain-water-to-ground-water-with-tube-in-the-area-of-tourism-in-yogyakarta" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48897.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">222</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Causes of Pokir in the Budgeting Process: Case Study in the Province of Jakarta, Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tri%20Nopiyanto">Tri Nopiyanto</a>, <a href="https://publications.waset.org/abstracts/search?q=Rahardhyani%20Dwiannisa"> Rahardhyani Dwiannisa</a>, <a href="https://publications.waset.org/abstracts/search?q=Arief%20Ismaryanto"> Arief Ismaryanto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One main issue for a certain region in order to achieve development is if the government that consists of the executive, legislative and judicial board are able to work together.

One of the example of the conflict is between the Local Government and Legislative Board (DPRD) in the Province of Jakarta in 2015. The cause of this conflict is because of the occurrence of pokir (pokok pikiran or ideas of budgeting). Pokir is driven by a budgeting plan that is arranged by DPRD that is supposed to be sourced from the aspiration of the people and delivered 5 months before the legalization of Local Government Budget (APBD), but the current condition in Jakarta is that pokir is a project by DPRD members itself and delivered just 3 days before the legalization in order to facilitate the interests of the members of the legislative. This paper discusses how pokir happens and what factors caused it. This paper uses political budgeting theory by Andy Norton and Diane Elson to analyze the issue. The method used in this paper is qualitative to collect the data and solve the problem of this research. The methods involved are in depth interview, experimental questionnaire, and literature studies. Results of this research are that Pokir occurs because of the distribution of power among DPRD members, between parties, executive, and legislative board. Beside that, Pokir also occurs because of the lack of the people’s participation in budgeting process and monitoring. Other than that, this paper also found that pokir also happens because of the budgeting system that is not able to provide a clean budgeting process, so it enables the creation of certain slots to add pokir into the budgets. Pokir also affects the development of Jakarta that goes through stagnation. This research recommends the implementation of e-budgeting to prevent the occurrence of pokir itself in the Province of Jakarta. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=legislative%20and%20executive%20board" title="legislative and executive board">legislative and executive board</a>, <a href="https://publications.waset.org/abstracts/search?q=Jakarta" title=" Jakarta"> Jakarta</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20budgeting" title=" political budgeting"> political budgeting</a>, <a href="https://publications.waset.org/abstracts/search?q=Pokir" title=" Pokir"> Pokir</a> </p> <a href="https://publications.waset.org/abstracts/64314/causes-of-pokir-in-the-budgeting-process-case-study-in-the-province-of-jakarta-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64314.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">270</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Development and Validation Method for Quantitative Determination of Rifampicin in Human Plasma and Its Application in Bioequivalence Test</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Endang%20Lukitaningsih">Endang Lukitaningsih</a>, <a href="https://publications.waset.org/abstracts/search?q=Fathul%20Jannah"> Fathul Jannah</a>, <a href="https://publications.waset.org/abstracts/search?q=Arief%20R.%20Hakim"> Arief R.

RIF has been used worldwide as first line drug-prescribed throughout tuberculosis therapy. This study aims to develop and to validate an HPLC method couple with a UV detection for determination of rifampicin in spiked human plasma and its application for bioequivalence study. The chromatographic separation was achieved on an RP-C18 column (LachromHitachi, 250 x 4.6 mm., 5μm), utilizing a mobile phase of phosphate buffer/acetonitrile (55:45, v/v, pH 6.8 ± 0.1) at a flow of 1.5 mL/min. Detection was carried out at 337 nm by using spectrophotometer. The developed method was statistically validated for the linearity, accuracy, limit of detection, limit of quantitation, precise and specifity. The specifity of the method was ascertained by comparing chromatograms of blank plasma and plasma containing rifampicin; the matrix and rifampicin were well separated. The limit of detection and limit of quantification were 0.7 µg/mL and 2.3 µg/mL, respectively. The regression curve of standard was linear (r > 0.999) over a range concentration of 20.0 – 100.0 µg/mL. The mean recovery of the method was 96.68 ± 8.06 %. Both intraday and interday precision data showed reproducibility (R.S.D. 2.98% and 1.13 %, respectively). Therefore, the method can be used for routine analysis of rifampicin in human plasma and in bioequivalence study. The validated method was successfully applied in pharmacokinetic and bioequivalence study of rifampicin tablet in a limited number of subjects (under an Ethical Clearance No. KE/FK/6201/EC/2015). The mean values of Cmax, Tmax, AUC(0-24) and AUC(o-∞) for the test formulation of rifampicin were 5.81 ± 0.88 µg/mL, 1.25 hour, 29.16 ± 4.05 µg/mL. h. and 29.41 ± 4.07 µg/mL. h., respectively. Meanwhile for the reference formulation, the values were 5.04 ± 0.54 µg/mL, 1.31 hour, 27.20 ± 3.98 µg/mL.h. and 27.49 ± 4.01 µg/mL.h. From bioequivalence study, the 90% CIs for the test formulation/reference formulation ratio for the logarithmic transformations of Cmax and AUC(0-24) were 97.96-129.48% and 99.13-120.02%, respectively. According to the bioequivamence test guidelines of the European Commission-European Medicines Agency, it can be concluded that the test formulation of rifampicin is bioequivalence with the reference formulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=validation" title="validation">validation</a>, <a href="https://publications.waset.org/abstracts/search?q=HPLC" title=" HPLC"> HPLC</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma" title=" plasma"> plasma</a>, <a href="https://publications.waset.org/abstracts/search?q=bioequivalence" title=" bioequivalence"> bioequivalence</a> </p> <a href="https://publications.waset.org/abstracts/67457/development-and-validation-method-for-quantitative-determination-of-rifampicin-in-human-plasma-and-its-application-in-bioequivalence-test" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67457.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">290</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> An Investigation of Performance Versus Security in Cognitive Radio Networks with Supporting Cloud Platforms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kurniawan%20D.%20Irianto">Kurniawan D.

Many studies about available spectrum have been done and it shows that licensed frequencies are idle most of the time. Cognitive radio is one of the solutions to solve those problems. Cognitive radio is a promising technology that allows the unlicensed users known as secondary users (SUs) to access licensed bands without making interference to licensed users or primary users (PUs). As cloud computing has become popular in recent years, cognitive radio networks (CRNs) can be integrated with cloud platform. One of the important issues in CRNs is security. It becomes a problem since CRNs use radio frequencies as a medium for transmitting and CRNs share the same issues with wireless communication systems. Another critical issue in CRNs is performance. Security has adverse effect to performance and there are trade-offs between them. The goal of this paper is to investigate the performance related to security trade-off in CRNs with supporting cloud platforms. Furthermore, Queuing Network Models with preemptive resume and preemptive repeat identical priority are applied in this project to measure the impact of security to performance in CRNs with or without cloud platform. The generalized exponential (GE) type distribution is used to reflect the bursty inter-arrival and service times at the servers. The results show that the best performance is obtained when security is disable and cloud platform is enable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=performance%20vs.%20security" title="performance vs. security">performance vs. security</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20radio%20networks" title=" cognitive radio networks"> cognitive radio networks</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20platforms" title=" cloud platforms"> cloud platforms</a>, <a href="https://publications.waset.org/abstracts/search?q=GE-type%20distribution" title=" GE-type distribution"> GE-type distribution</a> </p> <a href="https://publications.waset.org/abstracts/15106/an-investigation-of-performance-versus-security-in-cognitive-radio-networks-with-supporting-cloud-platforms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15106.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">346</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> Modification Of Rubber Swab Tool With Brush To Reduce Rubber Swab Fraction Fishing Time</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20R.%20Hidayat">T.

During the swab activity, problems occur frequent problems occur with the rubber swab. The rubber swab often breaks and becomes a fish inside the well. This rubber swab fishing activity caused the rig operation takes longer, the swab result data becomes too late and create potential losses of well operation for the company. The average time needed for fishing the fractions of rubber swab plus swab work is 42 hours. Innovation made for such problems is to modify the rubber swab tool. The rubber swab tool is modified by provided a series of brushes at the end part of the tool with a thread of connection in order to improve work safety, so when the rubber swab breaks, the broken swab will be lifted by the brush underneath; therefore, it reduces the loss time for rubber swab fishing. This tool has been applied, it and is proven that with this rubber swab tool modification, the rig operation becomes more efficient because it does not carry out the rubber swab fishing activity. The fish fractions of the rubber swab are lifted up to the surface. Therefore, it saves the fuel cost, and well production potentials are obtained. The average time to do swab work after the application of this modified tool is 8 hours. <p class="card-text"><strong>Keywords:</strong> <a
