Firms disclose their CSR activities, and some provide assurance to gain recognition as socially responsible firms. However, several of those socially responsible firms involve in tax scandals and raise a question of whether CSR disclosure is used to disguise firm misconduct or as a reflection of socially responsible firms. Specifically, whether firms engage in CSR disclosure and its assurance also responsible for their tax matters. This study examines the association between CSR disclosure and tax aggressiveness and the role of sustainability reporting assurance to the association. This research develops a modified index according to global reporting initiatives to measure CSR disclosure and various measurement for tax aggressiveness. Using a sample of Indonesian go public companies issued CSR disclosure, the empirical result shows that there is an association between CSR disclosure and tax aggressiveness. In addition, results also indicate sustainability reporting assurance moderate those association. The findings suggest that stakeholder in developing countries should examine carefully firms with active CSR disclosure before label it as socially responsible firms.

This is due to the increasing trend of disclosure of social responsibility in developing countries, even though this disclosure of information is still voluntary. On the other hand, developing countries have low taxation rate and investor protection infrastructures that allow the disclosure of social responsibility to be used opportunistically as a tool to fool the attainment of interests. This study also examines the role of assurance on the association between corporate social responsibility disclosure and tax aggressiveness. The assurance aims to provide confidence that the disclosure of social responsibility by the company is valid. This research builds an index to measure the disclosure of social responsibility based on the rules issued by the innovative Global Reporting. The results of the study are based on a sample of publicly traded companies in Thailand, which showed a positive association between disclosure of corporate social responsibility and tax aggressiveness, but it was further discovered that these results were mitigated by the existence of assurance against disclosure of corporate social responsibility. The results of this study indicate that the disclosure of corporate social responsibility can show that the company cares about the issue of social responsibility but does not automatically make the company as one that holds ethical values in its business practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corporate%20social%20responsibility%20disclosure" title="corporate social responsibility disclosure">corporate social responsibility disclosure</a>, <a href="https://publications.waset.org/abstracts/search?q=tax%20aggressiveness" title=" tax aggressiveness"> tax aggressiveness</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability%20assurance" title=" sustainability assurance"> sustainability assurance</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20ethics" title=" business ethics"> business ethics</a> </p> <a href="https://publications.waset.org/abstracts/115093/corporate-social-responsibility-disclosure-tax-aggressiveness-and-sustainability-report-assurance-evidence-from-thailand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115093.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">47</span> Single Fly Over as a Solution to Congestion of Intersection Junction: Case Study of Jalan Jatingaleh Semarang</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rachmat%20Mudiyono">Rachmat Mudiyono</a>, <a href="https://publications.waset.org/abstracts/search?q=Siti%20Sumiati"> Siti Sumiati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the next few years, traffic will happen most of the time. This was triggered by the growing rate of vehicles againts the road capacity which is not balance. All the time the congestion in the city of Semarang has been occured at peak hours. Congestion also occured in between Teuku Umar and Setia Budi road Jatingaleh because of a plot intersection (Kesatrian intersection, PLN intersection and Jatingaleh intersection) with the Toll Road. Jatingaleh is located in the southern city of Semarang which is a central meeting point between the upper and lower Semarang where the vehicle flows in through a combination of local current and regional traffic, and the flow of vehicles coming in and out from highway. The main cause of the problems that occurred in the area of Jatingaleh is due to the numbers of vehicles movement that occurs at the intersections. With the above issues, it is necessary to analyse the existing conditions and look into some solutions. Before carrying out an analysis of field surveys at peak hours for example morning (06:00 to 08:00 am) and for the afternoon (04:00 to 06:00 pm)should be conducted, then the number of vehicles is counted manually with “short-breakcounting” according to types of vehicles. From the analysis we found that the degree of saturation (DS) is 1.61 between Teuku Umar and Setia Budi road during the morning peak hours and 1.56 during the afternoon peak hours. This means that the capacity of the existing road is no longer able to accommodate the traffic flow. One of the solutions for the congestion that occurs at the intersection of Jatingaleh is to apply the efficiency of the intersection that is not in a plot with a Fly over, Underpass and the combination of Fly Over-Underpass. Base on the flow reduction calculation with 3 comparative modeling it shows that the Fly Over is the most technically efficient to be applied in this research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=single%20fly%20over" title="single fly over">single fly over</a>, <a href="https://publications.waset.org/abstracts/search?q=congestion" title=" congestion"> congestion</a>, <a href="https://publications.waset.org/abstracts/search?q=intersection" title=" intersection"> intersection</a>, <a href="https://publications.waset.org/abstracts/search?q=interchange" title=" interchange"> interchange</a> </p> <a href="https://publications.waset.org/abstracts/16536/single-fly-over-as-a-solution-to-congestion-of-intersection-junction-case-study-of-jalan-jatingaleh-semarang" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16536.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">392</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">46</span> The Effect of Concentrate Containing Probiotics on Fermentation Characteristics and in vitro Nutrient Digestibility</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20Santoso">B.

Two strains lactic acid bacteria (LAB) i.e Lactobacillus plantarum and Lactobacillus acidhophilus, and one strain yeast of Saccharomyces cerevisiae were used as probiotic. The probiotics was added at 2% and 4% (v/w) in the concentrate. The result showed the concentrate containing between 1.5 × 106 and 3 × 107 CFU/g of lactic acid bacteria and 3 × 103 CFU/g of S. cerevisiae. The DM, OM and NDF digestibility were higher (P<0.01) in grass substrate with concentrate than in grass alone. Addition of probiotic in concentrate increased (P<0.01) DM, OM and NDF compared to concentrate without probiotic. Total VFA and propionic acid concentrations were higher (P<0.01) in grass substrate with concentrate than in grass alone. Concentration of acetic acid decreased (P<0.01) in grass substrate with concentrate than in grass substrate alone. Addition of L. plantarum and L. acidophilus and S. cerevisiae in concentrate increased (P<0.01) propionic acid concentration. It was concluded that addition of probiotic in concentrate increased propionic concentration and in vitro nutrient digestibility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=by-products" title="by-products">by-products</a>, <a href="https://publications.waset.org/abstracts/search?q=concentrate" title=" concentrate"> concentrate</a>, <a href="https://publications.waset.org/abstracts/search?q=digestibility" title=" digestibility"> digestibility</a>, <a href="https://publications.waset.org/abstracts/search?q=probiotics" title=" probiotics"> probiotics</a> </p> <a href="https://publications.waset.org/abstracts/7142/the-effect-of-concentrate-containing-probiotics-on-fermentation-characteristics-and-in-vitro-nutrient-digestibility" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7142.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">392</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> The Application of Animal Welfare for Slaughterhouses in Bali Island</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Budi%20B.%20Leksono">Budi B.

SOS is a new approach in metaheuristics fields and never been used to solve discrete problems. A sophisticated decoding method to deal with a discrete problem setting in CVRP is applied using the basic symbiotic organism search (SOS) framework. The performance of the algorithm was evaluated on a set of benchmark instances and compared results with best known solution. The computational results show that the proposed algorithm can produce good solution as a preliminary testing.

In determining pregnancy, ultrasonography has many roles, such as to check the position of the fetus, abnormal pregnancy, fetal age and others. Unfortunately, all these things still need to analyze the role of the obstetrician in the sense of image raised by ultrasonography. One of the most striking is the determination of gestational age. Usually, it is done by measuring the length of the fetus manually by obstetricians. In this study, we developed a computer-aided diagnosis for the determination of gestational age by measuring the length of the fetus automatically using edge detection method and image morphology. Results showed that the system is sufficiently accurate in determining the gestational age based image processing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computer%20aided%20diagnosis" title="computer aided diagnosis">computer aided diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=gestational%20age" title=" gestational age"> gestational age</a>, <a href="https://publications.waset.org/abstracts/search?q=and%20diameter%20of%20uterus" title=" and diameter of uterus"> and diameter of uterus</a>, <a href="https://publications.waset.org/abstracts/search?q=length%20of%20fetus" title=" length of fetus"> length of fetus</a>, <a href="https://publications.waset.org/abstracts/search?q=edge%20detection%20method" title=" edge detection method"> edge detection method</a>, <a href="https://publications.waset.org/abstracts/search?q=morphology%20image" title=" morphology image"> morphology image</a> </p> <a href="https://publications.waset.org/abstracts/46484/edge-detection-and-morphological-image-for-estimating-gestational-age-based-on-fetus-length-automatically" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46484.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">295</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> Soil Characteristics and Liquefaction Potential of the Bengkulu Region Based on the Microtremor Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aditya%20Setyo%20Rahman">Aditya Setyo Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Dwikorita%20Karnawati"> Dwikorita Karnawati</a>, <a href="https://publications.waset.org/abstracts/search?q=Muzli"> Muzli</a>, <a href="https://publications.waset.org/abstracts/search?q=Dadang%20Permana"> Dadang Permana</a>, <a href="https://publications.waset.org/abstracts/search?q=Sigit%20Pramono"> Sigit Pramono</a>, <a href="https://publications.waset.org/abstracts/search?q=Fajri%20Syukur%20Rahmatullah"> Fajri Syukur Rahmatullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Oriza%20Sativa"> Oriza Sativa</a>, <a href="https://publications.waset.org/abstracts/search?q=Moehajirin"> Moehajirin</a>, <a href="https://publications.waset.org/abstracts/search?q=Edy%20Santoso"> Edy Santoso</a>, <a href="https://publications.waset.org/abstracts/search?q=Nur%20Hidayati%20Oktavia"> Nur Hidayati Oktavia</a>, <a href="https://publications.waset.org/abstracts/search?q=Ardian%20Yudhi%20Octantyo"> Ardian Yudhi Octantyo</a>, <a href="https://publications.waset.org/abstracts/search?q=Robby%20Wallansha"> Robby Wallansha</a>, <a href="https://publications.waset.org/abstracts/search?q=Juwita%20Sari%20Pradita"> Juwita Sari Pradita</a>, <a href="https://publications.waset.org/abstracts/search?q=Nur%20Fani%20Habibah"> Nur Fani Habibah</a>, <a href="https://publications.waset.org/abstracts/search?q=Audia%20Kaluku"> Audia Kaluku</a>, <a href="https://publications.waset.org/abstracts/search?q=Amelia%20Chelcea"> Amelia Chelcea</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoga%20Dharma%20Persada"> Yoga Dharma Persada</a>, <a href="https://publications.waset.org/abstracts/search?q=Anton%20Sugiharto"> Anton Sugiharto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Earthquake vibrations on the surface are not only affected by the magnitude of the earthquake and the distance from the hypocenter but also by the characteristics of the local soil. Variations and changes in soil characteristics from the depth of the bedrock to the surface can cause an amplification of earthquake vibrations that also affect the impact they may have on the surface. Soil characteristics vary widely even at relatively close distances, so for earthquake hazard mapping in cities with earthquake threats, it is necessary to study the characteristics of the local soil on a detailed or micro-scale (microzonation). This study proposes seismic microzonation and liquefaction potential based on microtremor observations. We carried out 143 microtremor observations, and the observation sites were spread across all populated sub-districts in Bengkulu City; the results showed that the dominance of Bengkulu City had medium soil types with a dominant period value of 0.4 < T₀ < 0.6, and there was one location with soft soil characteristics in the river, shaved with T₀ > 0.6. These results correlate with the potential for liquefaction as indicated by a seismic vulnerability index (K𝓰) greater than 5. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microtremor" title="microtremor">microtremor</a>, <a href="https://publications.waset.org/abstracts/search?q=dominant%20period" title=" dominant period"> dominant period</a>, <a href="https://publications.waset.org/abstracts/search?q=microzonation" title=" microzonation"> microzonation</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20vulnerability%20index" title=" seismic vulnerability index"> seismic vulnerability index</a> </p> <a href="https://publications.waset.org/abstracts/159784/soil-characteristics-and-liquefaction-potential-of-the-bengkulu-region-based-on-the-microtremor-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159784.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">121</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">40</span> Uncertainty in Near-Term Global Surface Warming Linked to Pacific Trade Wind Variability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Hadi%20Bordbar">M.

However, over two recent decades (1992-2011) there was a strong intensification of the Pacific Trade Winds that is linked with a slowdown in global surface warming. Using large ensembles of multiple climate models forced by increasing atmospheric greenhouse gas concentrations and starting from different ocean and/or atmospheric initial conditions, we reveal very diverse 20-year trends in the tropical Pacific climate associated with a considerable uncertainty in the globally averaged surface air temperature (SAT) in each model ensemble. This result suggests low confidence in our ability to accurately predict SAT trends over 20-year timescale only from external forcing. We show, however, that the uncertainty can be reduced when the initial oceanic state is adequately known and well represented in the model. Our analyses suggest that internal variability in the Pacific trade winds can mask the anthropogenic signal over a 20-year time frame, and drive transitions between periods of accelerated global warming and temporary slowdown periods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=trade%20winds" title="trade winds">trade winds</a>, <a href="https://publications.waset.org/abstracts/search?q=walker%20circulation" title=" walker circulation"> walker circulation</a>, <a href="https://publications.waset.org/abstracts/search?q=hiatus%20in%20the%20global%20surface%20warming" title=" hiatus in the global surface warming"> hiatus in the global surface warming</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20climate%20variability" title=" internal climate variability"> internal climate variability</a> </p> <a href="https://publications.waset.org/abstracts/91567/uncertainty-in-near-term-global-surface-warming-linked-to-pacific-trade-wind-variability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91567.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">268</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> Improvement of Transient Voltage Response Using PSS-SVC Coordination Based on ANFIS-Algorithm in a Three-Bus Power System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I%20Made%20Ginarsa">I Made Ginarsa</a>, <a href="https://publications.waset.org/abstracts/search?q=Agung%20Budi%20Muljono"> Agung Budi Muljono</a>, <a href="https://publications.waset.org/abstracts/search?q=I%20Made%20Ari%20Nrartha"> I Made Ari Nrartha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Transient voltage response appears in power system operation when an additional loading is forced to load bus of power systems. In this research, improvement of transient voltage response is done by using power system stabilizer-static var compensator (PSS-SVC) based on adaptive neuro-fuzzy inference system (ANFIS)-algorithm. The main function of the PSS is to add damping component to damp rotor oscillation through automatic voltage regulator (AVR) and excitation system. Learning process of the ANFIS is done by using off-line method where data learning that is used to train the ANFIS model are obtained by simulating the PSS-SVC conventional. The ANFIS model uses 7 Gaussian membership functions at two inputs and 49 rules at an output. Then, the ANFIS-PSS and ANFIS-SVC models are applied to power systems. Simulation result shows that the response of transient voltage is improved with settling time at the time of 4.25 s. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=improvement" title="improvement">improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=transient%20voltage" title=" transient voltage"> transient voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=PSS-SVC" title=" PSS-SVC"> PSS-SVC</a>, <a href="https://publications.waset.org/abstracts/search?q=ANFIS" title=" ANFIS"> ANFIS</a>, <a href="https://publications.waset.org/abstracts/search?q=settling%20time" title=" settling time"> settling time</a> </p> <a href="https://publications.waset.org/abstracts/4811/improvement-of-transient-voltage-response-using-pss-svc-coordination-based-on-anfis-algorithm-in-a-three-bus-power-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4811.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">578</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">38</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">37</span> Developing Ergonomic Prototype Testing Method for Manual Material Handling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Nugroho%20Doyo%20Yekti">Yusuf Nugroho Doyo Yekti</a>, <a href="https://publications.waset.org/abstracts/search?q=Budi%20Praptono"> Budi Praptono</a>, <a href="https://publications.waset.org/abstracts/search?q=Fransiskus%20Tatas%20Dwi%20Atmaji"> Fransiskus Tatas Dwi Atmaji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is no ergonomic prototype testing method for manual material handling yet.

This study aims to provide a preventive solution by developing prediction model of the terrorist threat in Indonesia by using Bayesian network. There are eight stages to build the model, started from literature review, build and verify Bayesian belief network to what-if scenario. In order to build the model, four experts from different perspectives are utilized. This study finds several significant findings. First, news and the readiness of terrorist group are the most influent factor. Second, according to several scenarios of the news portion, it can be concluded that the higher positive news proportion, the higher probability of terrorist threat will occur. Therefore, the preventive solution to reduce the terrorist threat in Indonesia based on the model is by keeping the positive news portion to a maximum of 38%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bayesian%20network" title="Bayesian network">Bayesian network</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20analysis" title=" decision analysis"> decision analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20security%20system" title=" national security system"> national security system</a>, <a href="https://publications.waset.org/abstracts/search?q=text%20mining" title=" text mining"> text mining</a> </p> <a href="https://publications.waset.org/abstracts/1453/development-of-terrorist-threat-prediction-model-in-indonesia-by-using-bayesian-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1453.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">392</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> Attitude of Tertiary Students on Multiculturalism in Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Budi%20Annisa%20Sidi">Budi Annisa Sidi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Present-day Indonesia maintains a narrative of a culturally plural but unified nation. At the same time, multicultural policies extend different degrees of recognition, accommodation, toleration and even discrimination towards different socio-cultural groups. In conjunction with different ethnographic landscapes across regions in Indonesia, this approach leads to a varied experience and understanding of national identity and multiculturalism among people. As a result, governments seeking to maintain national unity while practicing multiculturalism have to juggle different expectations. This situation is examined through the microcosms of university students using questionnaires followed up by focus group discussions and personal interviews. A comparison between university students across four different provinces in Indonesia (Aceh, Jakarta, West Java and the Moluccas) highlights the influence of one’s surroundings on their perception of multiculturalism. Students in the more heterogeneous areas generally show more acceptance towards diversity compared to students in primarily homogenous areas who have little actual experience in dealing with diversity. Regardless of their environment, students claim to have positive feelings and a strong sense of attachment to Indonesia but hold different ideas of what constitutes an ideal Indonesian national identity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Indonesia" title="Indonesia">Indonesia</a>, <a href="https://publications.waset.org/abstracts/search?q=multiculturalism" title=" multiculturalism"> multiculturalism</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20identity" title=" national identity"> national identity</a>, <a href="https://publications.waset.org/abstracts/search?q=nationalism" title=" nationalism"> nationalism</a> </p> <a href="https://publications.waset.org/abstracts/91973/attitude-of-tertiary-students-on-multiculturalism-in-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91973.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">233</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">33</span> R Software for Parameter Estimation of Spatio-Temporal Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Budi%20Nurani%20Ruchjana">Budi Nurani Ruchjana</a>, <a href="https://publications.waset.org/abstracts/search?q=Atje%20Setiawan%20Abdullah"> Atje Setiawan Abdullah</a>, <a href="https://publications.waset.org/abstracts/search?q=I.%20Gede%20Nyoman%20Mindra%20Jaya"> I.

That is why meat can be a potential hazard to humans. Several ways have been done to inhibit bacterial population in an effort to prolong the meat shelf-life. However, aberration sometimes happens in the practices of meat preservation, for example by using chemical material that possessed strong antibacterial activity like formaldehyde. For health reason, utilization of formaldehyde as a food preservative was forbidden because of DNA damage resulting cancer and birth defects. Therefore, it is important to seek a natural food preservative that is not harmful to the body. This study aims to reveal the potency of cashew apple as natural food preservative by measuring its antibacterial activity and marinating effect on the bacterial growth of beef and chicken meat. Antibacterial activity was measured by The Kirby-Bauer method while bacterial growth was determined by total plate count method. The results showed that inhibition zone of 10-30% cashew apple extract significantly wider compared to 0% extract on the medium of E. coli, S. aureus, S. typii, and Bacillus sp. Furthermore, beef marinated with 20-30% cashew apple extract and chicken meat marinated with 5-15% extract significantly less in the total number of bacteria compared to 0% extract. It can be concluded that marinating with 5-30% cashew apple extract can effectively inhibit the bacterial growth of beef and chicken meat. Moreover, the concentration of extracts to inhibit bacterial populations in chicken meat was reached at the lower level compared to beef. Thus, cashew apple is potential as a natural food preservative. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacterial%20growth" title="bacterial growth">bacterial growth</a>, <a href="https://publications.waset.org/abstracts/search?q=cashew%20apple" title=" cashew apple"> cashew apple</a>, <a href="https://publications.waset.org/abstracts/search?q=marinating" title=" marinating"> marinating</a>, <a href="https://publications.waset.org/abstracts/search?q=meat" title=" meat"> meat</a> </p> <a href="https://publications.waset.org/abstracts/51485/effects-of-marinating-with-cashew-apple-extract-on-the-bacterial-growth-of-beef-and-chicken-meat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51485.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">276</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">31</span> Unconventional Hydrocarbon Management Strategy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Edi%20Artono">Edi Artono</a>, <a href="https://publications.waset.org/abstracts/search?q=Budi%20Tamtomo"> Budi Tamtomo</a>, <a href="https://publications.waset.org/abstracts/search?q=Gema%20Wahyudi%20Purnama"> Gema Wahyudi Purnama</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The world energy demand increasing extreamly high time by time, including domestic demand.

In this research, the physical characteristic of adsorbent was increased by grafting chitosan using acetate carboxymetyl chitosan (CC). Further, CC and Pectin (Pec) were crosslinked using cross-linking agent BADGE (bis phenol A diglycidyl ether) to get CC-Pec-BADGE (CPB) adsorbent. The cross-linking processes aim to form stable structure and resistance on acidic media. Furthermore, in order to increase the adsorption capacity in removing Pb(II), the adsorbent was added with NaCl to form macroporous adsorbent named CCPec-BADGE-Na (CPB-Na). The physical and chemical characteristics of the porogenic adsorbent structure were characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). The adsorption parameter of CPB-Na to adsorb Pb(II) ion was determined. The kinetics and thermodynamics of the bath sorption of Pb(II) on CPB-Na adsorbent and using chitosan and pectin as a comparison were also studied. The results showed that the CPB-Na biosorbent was stable on acidic media. It had a rough and porous surface area, increased and gave higher sorption capacity for removal of Pb(II) ion. The CPB-Na 1/1 and 1/3 adsorbent adsorbed Pb(II) with adsorption capacity of 45.48 mg/g and 45.97 mg/g respectively, whereas pectin and chitosan were of 39.20 mg /g and 24.67 mg /g respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=porogen" title="porogen">porogen</a>, <a href="https://publications.waset.org/abstracts/search?q=Pectin" title=" Pectin"> Pectin</a>, <a href="https://publications.waset.org/abstracts/search?q=Carboxymethyl%20Chitosan%20%28CC%29" title=" Carboxymethyl Chitosan (CC)"> Carboxymethyl Chitosan (CC)</a>, <a href="https://publications.waset.org/abstracts/search?q=CC-%20Pec-BADGE-Na" title=" CC- Pec-BADGE-Na"> CC- Pec-BADGE-Na</a> </p> <a href="https://publications.waset.org/abstracts/91832/kinetic-and-thermodynamic-modified-pectin-with-chitosan-by-forming-polyelectrolyte-complex-adsorbent-to-remediate-of-pbii" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91832.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">158</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> Sulfide Removal from Liquid Using Biofilm on Packed Bed of Salak Fruit Seeds </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Retno%20Ambarwati%20Sigit%20Lestari">Retno Ambarwati Sigit Lestari</a>, <a href="https://publications.waset.org/abstracts/search?q=Wahyudi%20Budi%20Sediawan"> Wahyudi Budi Sediawan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarto%20Sarto"> Sarto Sarto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study focused on the removal of sulfide from liquid solution using biofilm on packed bed of salak fruit seeds.

Southern Malang consists of several sub-districts that directly borders with the Indian Ocean, such as Donomulyo, Bantur, Gedangan, Sumbermanjing, Tirto Yudo, and Ampel Gading. This area has a high geotourism potential because of the existence of geodiversity such as beaches, waterfalls, caves, and karst area. However, to the best of the authors’ knowledge, there is still no systematic data that informs the geotourism potentials to the public. The aim of this research is to complete the lack of data and then arrange it systematically so it can be used for both tourism and research purposes. Research methods such as field observation, literature study, and depth interview to local people have been implemented. Aspects reviewed by visiting the field are accommodation, transportation, and the feasibility of a place to be geotourism object. The primary data was taken in Sumbermanjing, Gedangan, Bantur, and Donomulyo sub-district. A literature study is needed to determine the regional geology of Southern Malang and as a comparison to new data obtained in the field. The results of the literature study show that southern Malang consists of three formations: Wonosari Formation, Mandalaka Formation, and River-swamps Sediment Formation with the age range of Oligocene to Quaternary. Depth interviews have been conducted by involving local people with the aim of knowing cultural-history in the research area. From this research, the geotourism object distribution map has been made. The map also includes Geotrek and basic geological information of each object. The results of this research can support the development of geotourism in Southern Malang. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geodiversity" title="geodiversity">geodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=geology" title=" geology"> geology</a>, <a href="https://publications.waset.org/abstracts/search?q=geotourism" title=" geotourism"> geotourism</a>, <a href="https://publications.waset.org/abstracts/search?q=geotrek" title=" geotrek"> geotrek</a>, <a href="https://publications.waset.org/abstracts/search?q=southern%20Malang" title=" southern Malang"> southern Malang</a> </p> <a href="https://publications.waset.org/abstracts/95181/the-potential-of-southern-malang-as-geotourism-site-the-distribution-of-geodiversity-and-geotrek-in-southern-malang-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95181.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">175</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> Techno-Economic Study on the Potential of Dimethyl Ether (DME) as a Substitute for LPG</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Widya%20Anggraini%20Pamungkas">Widya Anggraini Pamungkas</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosana%20Budi%20Setyawati"> Rosana Budi Setyawati</a>, <a href="https://publications.waset.org/abstracts/search?q=Awaludin%20Fitroh%20Rifai"> Awaludin Fitroh Rifai</a>, <a href="https://publications.waset.org/abstracts/search?q=Candra%20Pangesti%20Setiawan"> Candra Pangesti Setiawan</a>, <a href="https://publications.waset.org/abstracts/search?q=Anatta%20Wahyu%20Budiiman"> Anatta Wahyu Budiiman</a>, <a href="https://publications.waset.org/abstracts/search?q=Inayati"> Inayati</a>, <a href="https://publications.waset.org/abstracts/search?q=Joko%20Waluyo"> Joko Waluyo</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunu%20Herwi%20Pranolo"> Sunu Herwi Pranolo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increase in LPG consumption in Indonesia is not balanced with the amount of supply. The high demand for LPG due to the success of the government's kerosene-to-LPG conversion program and the Covid-19 pandemic in 2020 led to an increase in LPG consumption in the household sector and caused Indonesia's trade balance to experience a deficit. The high consumption of LPG encourages the need for alternative fuels as a substitute or which aims to substitute LPG; one of the materials that can be used is Dimethyl Ether (DME). Dimethyl ether (DME) is an organic compound with the chemical formula CH 3. OCH 3 has a high cetane number and has characteristics similar to LPG. DME can be produced from various sources, such as coal, biomass and natural gas. Based on the economic analysis conducted at 10% IRR, coal has the largest NPV of Rp. 20,034,837,497,241 with a payback period of 3.86 years, then biomass with an NPV of Rp. 10,401,526,072,850 and a payback period of 5.16. the latter is natural gas with an NPV of IDR 7,401,272,559,191 and a payback period of 6.17 years. Of the three sources of raw materials used, if the sensitivity is calculated using the selling price of DME equal to the selling price of LPG, it will get an NPV value that is greater than the NPV value when using the current DME price. The advantages of coal as a raw material for DME are not only because it is profitable, namely: low price and abundant resources, but has high greenhouse gas emissions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LPG" title="LPG">LPG</a>, <a href="https://publications.waset.org/abstracts/search?q=DME" title=" DME"> DME</a>, <a href="https://publications.waset.org/abstracts/search?q=coal" title=" coal"> coal</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass" title=" biomass"> biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20gas" title=" natural gas"> natural gas</a> </p> <a href="https://publications.waset.org/abstracts/161115/techno-economic-study-on-the-potential-of-dimethyl-ether-dme-as-a-substitute-for-lpg" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161115.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">124</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> The Implementation of Special Grammar Circle (Spegraci) as the Media Innovation for Blind People to Learn English Tenses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aji%20Budi%20Rinekso">Aji Budi Rinekso</a>, <a href="https://publications.waset.org/abstracts/search?q=Revika%20Niza%20Artiyana"> Revika Niza Artiyana</a>, <a href="https://publications.waset.org/abstracts/search?q=Lisa%20Widayanti"> Lisa Widayanti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> English is one of the international languages in the world.

Simulation results show that the presented PSS is able to maintain the stability by decreasing peak overshoot to the value of −2.56 × 10−5 pu for rotor speed deviation Δω2−3. The presented PSS also makes the settling time to achieve at 3.78 s on local mode oscillation. Furthermore, the presented PSS is able to improve the peak overshoot and settling time of Δω3−9 to the value of −0.868 × 10−5 pu and at the time of 3.50 s for inter-area oscillation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ANFIS" title="ANFIS">ANFIS</a>, <a href="https://publications.waset.org/abstracts/search?q=large-scale" title=" large-scale"> large-scale</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20system" title=" power system"> power system</a>, <a href="https://publications.waset.org/abstracts/search?q=PSS" title=" PSS"> PSS</a>, <a href="https://publications.waset.org/abstracts/search?q=stability%20enhancement" title=" stability enhancement"> stability enhancement</a> </p> <a href="https://publications.waset.org/abstracts/56457/stability-enhancement-of-a-large-scale-power-system-using-power-system-stabilizer-based-on-adaptive-neuro-fuzzy-inference-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56457.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">306</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> Seismic Microzonation Analysis for Damage Mapping of the 2006 Yogyakarta Earthquake, Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fathul%20Mubin">Fathul Mubin</a>, <a href="https://publications.waset.org/abstracts/search?q=Budi%20E.%20Nurcahya"> Budi E.

This is the basis need to investigate the seismic vulnerability index in around of the earthquake zone. This research is called microzonation of earthquake hazard. This research has been conducted at the site and surrounding of Prambanan Temple, includes homes and civil buildings. The reason this research needs to be done because in the event of an earthquake in 2006, there was damage to the temples at Prambanan temple complex and its surroundings. In this research, data collection carried out for 60 minutes using three component seismograph measurements at 165 points with spacing of 1000 meters. The data recorded in time function were analyzed using the spectral ratio method, known as the Horizontal to Vertical Spectral Ratio (HVSR). Results from this analysis are dominant frequency (Fg) and maximum amplification factor (Ag) are used to obtain seismic vulnerability index. The results of research showed the dominant frequency range from 0.5 to 30 Hz and the amplification is in interval from 0.5 to 9. Interval value for seismic vulnerability index is 0.1 to 50.

Indeed, pro-inflammatory cytokines Mycobacterium tuberculosis antigen-specific CD4+ and CD8+ T cells and NK cells increase the level of production of IFN-γ, a cytokine critical for augmenting the microbicidal activity of phagocytes. On the other hand, M. tuberculosis reduces the effects of IFN-γ by inhibiting the transcription of IFN-γ- responsive genes and by inducing the secretion of IL-6, which inhibits IFN-γ signaling. Probiotics Lactobacillus sp. and Bifidobacterium sp. were known to increase IFN-γ production in vivo, while vitamin B1, B6, and B12 worked on macrophages and releasing cytokines. Therefore, the present study was to evaluate the effect of probiotics and vitamin B supplement on changes of plasma cytokine levels in active pulmonary TB. From October to November 2016, twelve M. tuberculosis-infected patients starting anti-TB drugs were recruited, then divided into two groups. Seven patients were given a combination of probiotics and vitamin B, while five patients were in the control group. Plasma IFN-γ and IL-6 levels were measured by the ELISA kit before and a month after treatment. IFN-γ levels raised in four patients receiving the supplement (P = 0.743), while IL-6 increased in three patients in this group until day 30 of treatment (P = 0.298). Taken together, these results show the promising effect of probiotics and vitamin B on stimulation of IFN-γ and IL-6 production during intensive therapy of TB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interferon-gamma" title="interferon-gamma">interferon-gamma</a>, <a href="https://publications.waset.org/abstracts/search?q=interleukin-6" title=" interleukin-6"> interleukin-6</a>, <a href="https://publications.waset.org/abstracts/search?q=probiotic" title=" probiotic"> probiotic</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberculosis" title=" tuberculosis"> tuberculosis</a> </p> <a href="https://publications.waset.org/abstracts/62781/effect-of-probiotics-and-vitamin-b-on-plasma-interferon-gamma-and-interleukin-6-levels-in-active-pulmonary-tuberculosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62781.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">349</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> Heavy Sulphide Material Characterization of Grasberg Block Cave Mine, Mimika, Papua: Implication for Tunnel Development and Mill Issue</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cahya%20Wimar%20Wicaksono">Cahya Wimar Wicaksono</a>, <a href="https://publications.waset.org/abstracts/search?q=Reynara%20Davin%20Chen"> Reynara Davin Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Alvian%20Kristianto%20Santoso"> Alvian Kristianto Santoso</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Grasberg Cu-Au ore deposit as one of the biggest porphyry deposits located in Papua Province, Indonesia produced by several intrusion that restricted by Heavy Sulphide Zone (HSZ) in peripheral. HSZ is the rock that becomes the contact between Grassberg Igneous Complex (GIC) with sedimentary and igneous rock outside, which is rich in sulphide minerals such as pyrite ± pyrrhotite. This research is to obtain the characteristic of HSZ based on geotechnical, geochemical and mineralogy aspect and those implication for daily mining operational activities. Method used in this research are geological and alteration mapping, core logging, FAA (Fire Assay Analysis), AAS (Atomic absorption spectroscopy), RQD (Rock Quality Designation) and rock water content. Data generated from methods among RQD data, mineral composition and grade, lithological and structural geology distribution in research area. The mapping data show that HSZ material characteristics divided into three type based on rocks association, there are near igneous rocks, sedimentary rocks and on HSZ area. And also divided based on its location, north and south part of research area. HSZ material characteristic consist of rock which rich of pyrite ± pyrrhotite, and RQD range valued about 25%-100%. Pyrite ± pyrrhotite which outcropped will react with H₂O and O₂ resulting acid that generates corrosive effect on steel wire and rockbolt. Whereas, pyrite precipitation proses in HSZ forming combustible H₂S gas which is harmful during blasting activities. Furthermore, the impact of H₂S gas in blasting activities is forming poison gas SO₂. Although HSZ high grade Cu-Au, however those high grade Cu-Au rich in sulphide components which is affected in flotation milling process. Pyrite ± pyrrhotite in HSZ will chemically react with Cu-Au that will settle in milling process instead of floating. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=combustible" title="combustible">combustible</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosive" title=" corrosive"> corrosive</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20sulphide%20zone" title=" heavy sulphide zone"> heavy sulphide zone</a>, <a href="https://publications.waset.org/abstracts/search?q=pyrite%20%C2%B1%20pyrrhotite" title=" pyrite ± pyrrhotite"> pyrite ± pyrrhotite</a> </p> <a href="https://publications.waset.org/abstracts/82797/heavy-sulphide-material-characterization-of-grasberg-block-cave-mine-mimika-papua-implication-for-tunnel-development-and-mill-issue" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82797.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">326</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> Factors Affecting Customer Loyalty in the Independent Surveyor Service Industry in Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sufrin%20Hannan">Sufrin Hannan</a>, <a href="https://publications.waset.org/abstracts/search?q=Budi%20Suharjo"> Budi Suharjo</a>, <a href="https://publications.waset.org/abstracts/search?q=Rita%20Nurmalina"> Rita Nurmalina</a>, <a href="https://publications.waset.org/abstracts/search?q=Kirbrandoko"> Kirbrandoko</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The challenge for independent surveyor service companies now is growing with increasing uncertainty in business. Protection from the government for domestic independent surveyor industry from competitor attack, such as entering the global surveyors to Indonesia also no longer exists. Therefore, building customer loyalty becomes very important to create a long-term relationship between an independent surveyor with its customers. This study aims to develop a model that can be used to build customer loyalty by looking at various factors that determine customer loyalty, especially on independent surveyors for coal inspection in Indonesia. The development of this model uses the relationship marketing approach. Testing of the hypothesis is done by testing the variables that determine customer loyalty, either directly or indirectly, which amounted to 10 variables. The data were collected from 200 questionnaires filled by independent surveyor company decision makers from 51 exporting companies and coal trading companies in Indonesia and analyzed using Structural Equation Model (SEM). The results show that customer loyalty of independent surveyors is influenced by customer satisfaction, trust, switching-barrier, and relationship-bond. Research on customer satisfaction shows that customer satisfaction is influenced by the perceived quality and perceived value, while perceived quality is influenced by reliability, assurance, responsiveness, and empathy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=relationship%20marketing" title="relationship
