Experiment works consisted of acid activation and adsorption experiments. The natural zeolite sample was activated using 0.3 M HCl at the temperature of 353 K. In the adsorption experiments the feed gas concentrations were 40 and 80 % CO2 in helium within various temperatures of 303; 323 and 373 K. The experiments were conducted by using transient step change adsorption and 20 % Ar/He tracer experiment was conducted to measure dispersion and time lag effect of the packed bed system. A mathematical model of CO2 adsorption had been set up by assuming plug flow;isothermal;isobaric and no gas film mass transport resistance. Single site Langmuir physisorption and Maxwell Stefan mass transport in micropore were applied. All the data were then optimized to get the best value of modified fitted parameter. The model was in a good agreement with the experiment data. Diffusivity tended to increase by increasing temperatures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=Langmuir" title=" Langmuir"> Langmuir</a>, <a href="https://publications.waset.org/abstracts/search?q=Maxwell-Stefan" title=" Maxwell-Stefan"> Maxwell-Stefan</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20zeolite" title=" natural zeolite"> natural zeolite</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20diffusion" title=" surface diffusion"> surface diffusion</a> </p> <a href="https://publications.waset.org/abstracts/50699/co2-adsorption-on-the-activated-klaten-indonesian-natural-zeolite-in-a-packed-bed-adsorber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50699.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">179</span> Optimized Microwave Pretreatment of Rice Straw for Conversion into Lignin Free and High Crystalline Cellulose</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Ishfaq%20Bhat">Mohd Ishfaq Bhat</a>, <a href="https://publications.waset.org/abstracts/search?q=Navin%20Chandra%20Shahi"> Navin Chandra Shahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Umesh%20Chandra%20Lohani"> Umesh Chandra Lohani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study aimed to evaluate the effect of microwave application in synergy with the conventional sodium chlorite delignification of rice straw biomass. For the study, Box-Behnken experimental design involving four independent parameters, each with three levels viz. microwave power (480-800 W), irradiation time (4-12 min), bleaching solution concentration (0.4-3.0%), and bleaching time (1-5h) was used. The response was taken in the form of delignification percentage. The optimization of process parameters was done through response surface methodology. The respective optimum parameters of microwave power, irradiation time, bleaching solution concentration, and bleaching time were obtained as 671 W, 8.66 min, 2.67%, and 1h. The delignification percentage achieved at optimum conditions was 93.51%. The spectral, morphological, and x-ray diffraction characteristics of the rice straw powder after delignification showed a complete absence of lignin peaks, deconstruction of lignocellulose complex, and an increase of crystallinity (from 39.8 to 61.6 %). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lignocellulosic%20biomass" title="lignocellulosic biomass">lignocellulosic biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=delignification" title=" delignification"> delignification</a>, <a href="https://publications.waset.org/abstracts/search?q=microwaves" title=" microwaves"> microwaves</a>, <a href="https://publications.waset.org/abstracts/search?q=rice%20straw" title=" rice straw"> rice straw</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization" title=" characterization"> characterization</a> </p> <a href="https://publications.waset.org/abstracts/146950/optimized-microwave-pretreatment-of-rice-straw-for-conversion-into-lignin-free-and-high-crystalline-cellulose" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146950.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">147</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">178</span> Enhancing the Network Security with Gray Code</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Adi%20Purnomo%20Sidhi">Thomas Adi Purnomo Sidhi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, network is an essential need in almost every part of human daily activities.

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">174</span> Metamodel for Artefacts in Service Engineering Analysis and Design </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> </p> <p class="card-text"><strong>Abstract:</strong></p> As a process of developing a service system, the term ‘service engineering’ evolves in scope and definition. To achieve an integrated understanding of the process, a general framework and an ontology are required. This paper extends a previously built service engineering framework by exploring metamodels for the framework artefacts based on a foundational ontology and a metamodel landscape. The first part of this paper presents a correlation map between the proposed framework with the ontology as a form of evaluation for the conceptual coverage of the framework. The mapping also serves to characterize the artefacts to be produced for each activity in the framework. The second part describes potential metamodels to be used, from the metamodel landscape, as alternative formats of the framework artefacts. The results suggest that the framework sufficiently covers the ontological concepts, both from general service context and software service context. The metamodel exploration enriches the suggested artefact format from the original eighteen formats to thirty metamodel alternatives. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artefact" title="artefact">artefact</a>, <a href="https://publications.waset.org/abstracts/search?q=framework" title=" framework"> framework</a>, <a href="https://publications.waset.org/abstracts/search?q=service" title=" service"> service</a>, <a href="https://publications.waset.org/abstracts/search?q=metamodel" title=" metamodel"> metamodel</a> </p> <a href="https://publications.waset.org/abstracts/98180/metamodel-for-artefacts-in-service-engineering-analysis-and-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98180.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">207</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">173</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">189</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">172</span> Amplified Ribosomal DNA Restriction Analysis Method to Assess Rumen Microbial Diversity of Ruminant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Natsir">A.

High rumen degradation rate of faba bean protein may lead to inconstant rumen conditions that could have a prominent impact on rumen microbial diversity. Amplified Ribosomal DNA Restriction Analysis (ARDRA) is utilized to monitor diversity of rumen microbes on sheep fed low quality forage supplemented by faba beans. Four mature merino sheep with existing rumen cannula were used in this study according to 4 x 4 Latin square design. The results of study indicated that there were 37 different ARDRA types identified out of 136 clones examined. Among those clones, five main clone types existed across the treatments with different percentages. In conclusion, the ARDRA method is potential to be used as a routine tool to assess the temporary changes in the rumen community as a result of different feeding strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ARDRA%20method" title="ARDRA method">ARDRA method</a>, <a href="https://publications.waset.org/abstracts/search?q=cattle" title=" cattle"> cattle</a>, <a href="https://publications.waset.org/abstracts/search?q=genomic%20diversity" title=" genomic diversity"> genomic diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=rumen%20microbes" title=" rumen microbes"> rumen microbes</a> </p> <a href="https://publications.waset.org/abstracts/55076/amplified-ribosomal-dna-restriction-analysis-method-to-assess-rumen-microbial-diversity-of-ruminant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55076.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">361</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">171</span> Ideal Posture in Regulating Legal Regulations in Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M%20Jeffri%20Arlinandes%20Chandra">M Jeffri Arlinandes Chandra</a>, <a href="https://publications.waset.org/abstracts/search?q=Puwaningdyah%20Murti%20Wahyuni"> Puwaningdyah Murti Wahyuni</a>, <a href="https://publications.waset.org/abstracts/search?q=Dewi%20Mutiara%20M%20Jeffri%20Arlinandes%20Chandra"> Dewi Mutiara M Jeffri Arlinandes Chandra</a>, <a href="https://publications.waset.org/abstracts/search?q=Puwaningdyah%20Murti%20Wahyuni"> Puwaningdyah Murti Wahyuni</a>, <a href="https://publications.waset.org/abstracts/search?q=Dewi%20Mutiara"> Dewi Mutiara</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Indonesia is a state of the law in accordance with article 1 paragraph 3 of the Constitution of the Republic of Indonesia (1945 Constitution), namely, 'the State of Indonesia is a state of law'. The consequences of the rule of law are making the law as the main commanding officer or making the law as a basis for carrying out an action taken by the state. The types of regulations and procedures for the formation of legislation in Indonesia are contained in Law Number 12 of 2011 concerning the Formation of Legislation. Various attempts were made to make quality regulations both in the formal hierarchy and material hierarchy such as synchronization and harmonization in the formation of laws and regulations so that there is no conflict between equal and hierarchical laws, but the fact is that there are still many conflicting regulations found between one another. This can be seen clearly in the many laws and regulations that were sued to judicial institutions such as the Constitutional Court (MK) and the Supreme Court (MA). Therefore, it is necessary to have a formulation regarding the governance of the formation of laws and regulations so as to minimize the occurrence of lawsuits to the court so that positive law can be realized which can be used today and for the future (ius constituendum). The research method that will be used in this research is a combination of normative research (library research) supported by empirical data from field research so that it can formulate concepts and answer the challenges being faced. First, the structuring of laws and regulations in Indonesia must start from the inventory of laws and regulations, whether they can be classified based on the type of legislation, what are they set about, the year of manufacture, etc. so that they can be clearly traced to the regulations relating to the formation of laws and regulations. Second, the search and revocation/revocation of laws and regulations that do not exist in the state registration system. Third, the periodic evaluation system is carried out at every level of the hierarchy of laws and regulations. These steps will form an ideal model of laws and regulations in Indonesia both in terms of content and material so that the instructions can be codified and clearly inventoried so that they can be accessed by the wider community as a concrete manifestation of the principle that all people know the law (presumptio iures de iure). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=legislation" title="legislation">legislation</a>, <a href="https://publications.waset.org/abstracts/search?q=review" title=" review"> review</a>, <a href="https://publications.waset.org/abstracts/search?q=evaluation" title=" evaluation"> evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=reconstruction" title=" reconstruction"> reconstruction</a> </p> <a href="https://publications.waset.org/abstracts/116950/ideal-posture-in-regulating-legal-regulations-in-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116950.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">149</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">170</span> Optimization of Sintering Process with Deteriorating Quality of Iron Ore Fines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chandra%20Shekhar%20Verma">Chandra Shekhar Verma</a>, <a href="https://publications.waset.org/abstracts/search?q=Umesh%20Chandra%20Mishra"> Umesh Chandra Mishra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Blast Furnace performance mainly depends on the quality of sinter as a major portion of iron-bearing material occupies by it hence its quality w.r.t. Tumbler Index (TI), Reducibility Index (RI) and Reduction Degradation Index (RDI) are the key performance indicators of sinter plant. Now it became very tough to maintain the desired quality with the increasing alumina (Al₂O₃) content in iron fines and study is focused on it. Alumina is a refractory material and required more heat input to fuse thereby affecting the desired sintering temperature, i.e. 1300°C. It goes in between the grain boundaries of the bond and makes it weaker. Sinter strength decreases with increasing alumina content, and weak sinter generates more fines thereby reduces the net sinter production as well as plant productivity. Presence of impurities beyond the acceptable norm: such as LOI, Al₂O₃, MnO, TiO₂, K₂O, Na₂O, Hydrates (Goethite & Limonite), SiO₂, phosphorous and zinc, has led to greater challenges in the thrust areas such as productivity, quality and cost. The ultimate aim of this study is maintaining the sinter strength even with high Al₂O without hampering the plant productivity. This study includes mineralogy test of iron fines to find out the fraction of different phases present in the ore and phase analysis of product sinter to know the distribution of different phases. Corrections were done focusing majorly on varying Al₂O₃/SiO₂ ratio, basicity: B2 (CaO/SiO₂), B3 (CaO+MgO/SiO₂) and B4 (CaO+MgO/SiO₂+Al₂O₃). The concept of Alumina / Silica ratio, B3 & B4 found to be useful. We used to vary MgO, Al₂O₃/SiO₂, B2, B3 and B4 to get the desired sinter strength even at high alumina (4.2 - 4.5%) in sinter. The study concludes with the establishment of B4, and Al₂O₃/SiO₂ ratio in between 1.53-1.60 and 0.63- 0.70 respectively and have achieved tumbler index (Drum Index) 76 plus with the plant productivity of 1.58-1.6 t/m2/hr. at JSPL, Raigarh. Study shows that despite of high alumina in sinter, its physical quality can be controlled by maintaining the above-mentioned parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Basicity-2" title="Basicity-2">Basicity-2</a>, <a href="https://publications.waset.org/abstracts/search?q=Basicity-3" title=" Basicity-3"> Basicity-3</a>, <a href="https://publications.waset.org/abstracts/search?q=Basicity-4" title=" Basicity-4"> Basicity-4</a>, <a href="https://publications.waset.org/abstracts/search?q=Sinter" title=" Sinter"> Sinter</a> </p> <a href="https://publications.waset.org/abstracts/85749/optimization-of-sintering-process-with-deteriorating-quality-of-iron-ore-fines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85749.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">172</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">169</span> Value Chain Identification of Beekeeping Business in Indonesia: Case Study of Four Beekeeping Business in West Java</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dwi%20Purnomo">Dwi Purnomo</a>, <a href="https://publications.waset.org/abstracts/search?q=Anas%20Bunyamin"> Anas Bunyamin</a>, <a href="https://publications.waset.org/abstracts/search?q=Fajar%20Susilo"> Fajar Susilo</a>, <a href="https://publications.waset.org/abstracts/search?q=Akbar%20Anugrah"> Akbar Anugrah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Beekeeping became a rural economic buffer, especially for people who lived by forest side to diversify their food or sell the honey and bee colony.

Especially in Wonogiri district, red cayenne pepper was the biggest sector contributing to inflation on 2016. A national statistic proved that in recent five years red cayenne pepper has the highest average level of fluctuation among all commodities. Some factors, like supply chain, price disparity, production quantity, crop failure, and oil price become the possible factor causes high volatility level in red cayenne pepper price. Therefore, this research tries to find the key factor causing fluctuation on red cayenne pepper by using ARCH/GARCH method. The method could accommodate the presence of heteroscedasticity in time series data. At the end of the research, it is statistically found that the second level of supply chain becomes the biggest part contributing to inflation with 3,35 of coefficient in fluctuation forecasting model of red cayenne pepper price. This model could become a reference to the government to determine the appropriate policy in maintaining the price stability of red cayenne pepper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ARCH%2FGARCH" title="ARCH/GARCH">ARCH/GARCH</a>, <a href="https://publications.waset.org/abstracts/search?q=forecasting" title=" forecasting"> forecasting</a>, <a href="https://publications.waset.org/abstracts/search?q=red%20cayenne%20pepper" title=" red cayenne pepper"> red cayenne pepper</a>, <a href="https://publications.waset.org/abstracts/search?q=volatility" title=" volatility"> volatility</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain" title=" supply chain"> supply chain</a> </p> <a href="https://publications.waset.org/abstracts/79137/designing-price-stability-model-of-red-cayenne-pepper-price-in-wonogiri-district-centre-java-using-archgarch-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79137.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">186</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">167</span> Energy in the Nexus of Defense and Border Security: Securing Energy Deposits in the Natuna Islands of Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Debby%20Rizqie%20Amelia%20Gustin">Debby Rizqie Amelia Gustin</a>, <a href="https://publications.waset.org/abstracts/search?q=Purnomo%20Yusgiantoro"> Purnomo Yusgiantoro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hydrocarbon energy is still pivotal to today’s economy, but its existence is continually declining. Thus, preserving future energy supply has become the national interest of many countries, which they cater in various way, from importing to expansion and occupation. Underwater of Natuna islands in Indonesia deposits great amount of natural gas reserved, numbered to 46 TCF (trillion cubic feet), which is highly potential to meet Indonesia future energy demand. On the other hand, there could be a possibility that others also seek this natural resources. Natuna is located in the borderline of Indonesia, directly adjacent to the South China Sea, an area which is prolonged to conflict. It is a challenge for Indonesia government to preserve their energy deposit in Natuna islands and to response accordingly if the tension in South China Sea rises. This paper examines that nowadays defense and border security is not only a matter of guarding a country from foreign invasion, but also securing its resources accumulated on the borderline. Countries with great amount of energy deposits on their borderline need to build up their defense capacity continually, to ensure their territory along with their energy deposits is free from any interferences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=border%20security" title="border security">border security</a>, <a href="https://publications.waset.org/abstracts/search?q=defense" title=" defense"> defense</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20interest" title=" national interest"> national interest</a>, <a href="https://publications.waset.org/abstracts/search?q=threat" title=" threat"> threat</a> </p> <a href="https://publications.waset.org/abstracts/61497/energy-in-the-nexus-of-defense-and-border-security-securing-energy-deposits-in-the-natuna-islands-of-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61497.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">482</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">166</span> Invitro Study of Anti-Leishmanial Property of Nigella Sativa Methanalic Black Seed Extract</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tawqeer%20Ali%20Syed">Tawqeer Ali Syed</a>, <a href="https://publications.waset.org/abstracts/search?q=Prakash%20Chandra"> Prakash Chandra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims to evaluate the antileishmanial activity of Nigella sativa black seed extract.

Numerous medical devices are sterilized by ionizing radiation. In the current research paper, an attempt was made to develop precise and inexpensive polymeric film dosimeter which can be used for controlling radiation dosage. Polymeric film containing (pH sensitive dye) indicator dye Bromophenol blue (BPB) was casted to check the effect of Gamma radiation on its optical and physical properties. The film was exposed to gamma radiation at 4 kGy/hr in the range of 0 to 300 kGy at an interval of 50 kGy. Release of vinyl acetate from an emulsion on high radiation reacts with the BPB fading the color of the film from blue to light blue and then finally colorless, indicating a change in pH from basic to acidic form. The change was characterized by using CIE l*a*b*, ultra-violet spectroscopy and FT-IR respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bromophenol%20blue" title="bromophenol blue">bromophenol blue</a>, <a href="https://publications.waset.org/abstracts/search?q=dosimeter" title=" dosimeter"> dosimeter</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma%20radiation" title=" gamma radiation"> gamma radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer" title=" polymer"> polymer</a> </p> <a href="https://publications.waset.org/abstracts/55840/effect-of-gamma-radiation-on-bromophenol-blue-dyed-films-as-dosimeter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55840.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">157</span> Estimation of Desktop E-Wastes in Delhi Using Multivariate Flow Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sumay%20Bhojwani">Sumay Bhojwani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashutosh%20Chandra"> Ashutosh Chandra</a>, <a href="https://publications.waset.org/abstracts/search?q=Mamita%20Devaburman"> Mamita Devaburman</a>, <a href="https://publications.waset.org/abstracts/search?q=Akriti%20Bhogal"> Akriti Bhogal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article uses the Material flow analysis for estimating e-wastes in the Delhi/NCR region. The Material flow analysis is based on sales data obtained from various sources. Much of the data available for the sales is unreliable because of the existence of a huge informal sector. The informal sector in India accounts for more than 90%. Therefore, the scope of this study is only limited to the formal one. Also, for projection of the sales data till 2030, we have used regression (linear) to avoid complexity. The actual sales in the years following 2015 may vary non-linearly but we have assumed a basic linear relation. The purpose of this study was to know an approximate quantity of desktop e-wastes that we will have by the year 2030 so that we start preparing ourselves for the ineluctable investment in the treatment of these ever-rising e-wastes. The results of this study can be used to install a treatment plant for e-wastes in Delhi. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=e-wastes" title="e-wastes">e-wastes</a>, <a href="https://publications.waset.org/abstracts/search?q=Delhi" title=" Delhi"> Delhi</a>, <a href="https://publications.waset.org/abstracts/search?q=desktops" title=" desktops"> desktops</a>, <a href="https://publications.waset.org/abstracts/search?q=estimation" title=" estimation"> estimation</a> </p> <a href="https://publications.waset.org/abstracts/37549/estimation-of-desktop-e-wastes-in-delhi-using-multivariate-flow-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37549.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">259</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">156</span> Assessment on Rumen Microbial Diversity of Bali Cattle Using 16S rRNA Sequencing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asmuddin%20Natsir">Asmuddin Natsir</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Mujnisa"> A.

This study was conducted to assess the diversity of rumen bacteria of bali cattle raised under traditional farming condition. Three adult bali cattle were used in this experiment. The rumen fluid samples from the three experimental animals were obtained by the Stomach Tube method before the morning feeding. The results of study indicated that the Illumina sequencing was successful in identifying 301,589 sequences, averaging 100,533 sequences, from three rumen fluid samples of three cattle. Furthermore, based on the SILVA taxonomic database, there were 19 kinds of phyla that had been successfully identified. Of the 19 phyla, there were only two dominant groups across the three samples, namely Bacteroidetes and Firmicutes, with an average percentage of 83.68% and 13.43%, respectively. Other groups such as Synergistetes, Spirochaetae, Planctomycetes can also be identified but in relatively small percentage. At the genus level, there were 157 sequences obtained from all three samples. Of this number, the most dominant group was Prevotella 1 with a percentage of 71.82% followed by 6.94% of Christencenellaceae R-7 group. Other groups such as Prevotellaceae UCG-001, Ruminococcaceae NK4A214 group, Sphaerochaeta, Ruminococcus 2, Rikenellaceae RC9 gut group, Quinella were also identified but with very low percentages. The sequencing results were able to detect the presence of 3.06% and 3.92% respectively for uncultured rumen bacterium and uncultured bacterium. In conclusion, the results of this experiment can provide an opportunity for a better understanding of the rumen bacterial diversity of the bali cattle raised under traditional farming condition and insight regarding the uncultured rumen bacterium and uncultured bacterium that need to be further explored. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=16S%20rRNA%20sequencing" title="16S rRNA sequencing">16S rRNA sequencing</a>, <a href="https://publications.waset.org/abstracts/search?q=bali%20cattle" title=" bali cattle"> bali cattle</a>, <a href="https://publications.waset.org/abstracts/search?q=rumen%20microbial%20diversity" title=" rumen microbial diversity"> rumen microbial diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=uncultured%20rumen%20bacterium" title=" uncultured rumen bacterium"> uncultured rumen bacterium</a> </p> <a href="https://publications.waset.org/abstracts/80303/assessment-on-rumen-microbial-diversity-of-bali-cattle-using-16s-rrna-sequencing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80303.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">336</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">155</span> Design of Decimation Filter Using Cascade Structure for Sigma Delta ADC </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Misbahuddin%20Mahammad">Misbahuddin Mahammad</a>, <a href="https://publications.waset.org/abstracts/search?q=P.%20Chandra%20Sekhar"> P.

The decimation filters work twofold; they decimate the sampling rate by a factor of OSR (oversampling rate) and they remove the out band quantization noise resulting in an increase in resolution. The speed, area and power consumption of oversampled converter are governed largely by decimation filters in sigma-delta A/D converters. The scope of the work is to design a decimation filter for sigma-delta ADC and simulation using MATLAB. The decimation filter structure is based on cascaded-integrated comb (CIC) filter. A second decimation filter is using CIC for large rate change and cascaded FIR filters, for small rate changes, to improve the frequency response.

A matrix function which is called the Permanent Function is derived. By substituting the level of inherent contribution of the influencing parameters and their influence on each other qualitatively, a criterion called Suitability Index is derived. Based on these indices, lubricants can be ranked for their suitability. The proposed model can be useful for maintenance engineers in selecting the best lubricant for a TOR application.

In our best knowledge manual therapy is often advocated for managing CH, but very little focus given on muscle system although it is a musculoskeletal disorder. In this study, 75 patients with CH were selected and divided into two groups Group A: Manual therapy and Group B: dry needling along with manual therapy group. Assessment was done using NPRS (0-10) for pain, wide spread pressure pain threshold using an algometer at the beginning and end of the study. There is a consistent reduction in pain and tenderness in both the group but significant improvement was shown in combined group.

To the best of the knowledge of the authors, till date there is no study, either experimental or analytical, which predict damping for CNF-PP composites at the nanoscale. Hence, this will be a valuable addition in the area of nanocomposites. Results show that with only 2% addition by volume of CNF in PP, E11 increases 748%. Increase in E22 is very less in comparison to the increase in E11. With increase in CNF aspect ratio (l/d) till l/d=60, the longitudinal loss factor (η11) decreases rapidly. Results of this study have been compared with those available in literature. <p class="card-text"><strong>Keywords:</strong> <a
