<p class="card-text"><strong>Abstract:</strong></p> Blue Swimming crab (Portunus pelagicus) is an important commercial species throughout the subtropical waters and as such constitutes part of the fisheries resources. Data are lacking on the morphological variations of selected fast-growing crabs reared in a pond. This study aimed to analyze the morphological and molecular character of a selected fast-growing crab reared in ponds in South of Sulawesi. The crab seeds were obtained from local fish-trap and hatchery. A study on the growth was carried out in the population of crabs. The dimensions analyzed were carapace width (CW) measured after 3 months of grow out. Morphological character states were examined based on the pattern of spots on the carapace. Molecular analysis was performed using RAPD (Random Amplified Polymorphic DNA). Genetic distance was analysed using TFPGA (Tools for Population Genetic Analyses) version 1.3. The results showed that there were variations in the growth of crabs. These crabs clustered morphologically into three quite distinct groups. The crab with white spots irregularly spread over its carapace was the largest size while the crab with large white spots scattered over the carapace was the smaller size (3%). The crab with small white spots scattered over the carapace was the smallest size found in this study. Molecular analysis showed that there are morphologically and genetically different between groups of crabs. Genetic distances among crabs ranged from 0.1527 to 0.5856. Thus, this study provides information the use of white spots pattern over carapace as indicators to identify the type of blue swimming crabs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crab" title="crab">crab</a>, <a href="https://publications.waset.org/abstracts/search?q=portunus%20pelagicus" title=" portunus pelagicus"> portunus pelagicus</a>, <a href="https://publications.waset.org/abstracts/search?q=morphology" title=" morphology"> morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=RAPD" title=" RAPD"> RAPD</a>, <a href="https://publications.waset.org/abstracts/search?q=Carapace" title=" Carapace"> Carapace</a> </p> <a href="https://publications.waset.org/abstracts/20407/morphological-and-molecular-analysis-of-selected-fast-growing-blue-swimming-crab-portunus-pelagicus-in-south-of-sulawesi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20407.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">538</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">50</span> Influence of Alcohol to Quality Iota Type Carrageenan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andi%20Hasizah%20Mochtar">Andi Hasizah Mochtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Meta%20Mahendradatta"> Meta Mahendradatta</a>, <a href="https://publications.waset.org/abstracts/search?q=Amran%20Laga"> Amran Laga</a>, <a href="https://publications.waset.org/abstracts/search?q=Metusalach%20Metusalach"> Metusalach Metusalach</a>, <a href="https://publications.waset.org/abstracts/search?q=Salengke%20Salengke"> Salengke Salengke</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariati%20Bilang"> Mariati Bilang</a>, <a href="https://publications.waset.org/abstracts/search?q=Andi%20Amijoyo%20Mochtar"> Andi Amijoyo Mochtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Reta%20Reta"> Reta Reta</a>, <a href="https://publications.waset.org/abstracts/search?q=Aminah%20Muhdar"> Aminah Muhdar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sri%20Suhartini"> Sri Suhartini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims to determine the effect of alcohol type on the quality of iota carrageenan-based on extraction technology through the application of ohmic reactor.

However, now this shrimp more death due to virus attack such as white spot disease caused by white spot syndrome virus (WSSV). Various efforts have done to prevent the disease, like immunostimulatory, probiotics, and vaccine. White spot syndrome virus (WSSV) envelope protein VP19 gene is important because of its involvement in the system infection of shrimp. This study aimed to isolate and characterize an envelope protein VP19 – encoding gene of WSSV using WSSV infected Vanname Shrimp sample from some areas in South Sulawesi (Pangkep, Barru and Pinrang). The genomic of DNA were isolated from shrimp muscle using DTAB-CTAB method. Isolation of gene encoding envelope protein VP19 WSSV ws successfully performed with the results of the length of DNA fragment was 387 bp. The results of homology analysis using BLASTn homology suggested that these isolates genes from Barru, Pangkep and Pinrang have closest relationship with isolates from Mexican. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vanname" title="vanname">vanname</a>, <a href="https://publications.waset.org/abstracts/search?q=shrimp" title=" shrimp"> shrimp</a>, <a href="https://publications.waset.org/abstracts/search?q=WSSV" title=" WSSV"> WSSV</a>, <a href="https://publications.waset.org/abstracts/search?q=viral%20protein%2019" title=" viral protein 19"> viral protein 19</a> </p> <a href="https://publications.waset.org/abstracts/20491/isolation-and-characterization-white-spot-syndrome-protein-envelope-protein-19-from-black-tiger-shrimp-penaeus-monodon" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20491.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">535</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">48</span> Bio-Nano Mask: Antivirus and Antimicrobial Mouth Mask Coating with Nano-TiO2 and Anthocyanin Utilization as an Effective Solution of High ARI Patients in Riau</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Annisa%20Ulfah%20Pristya">Annisa Ulfah Pristya</a>, <a href="https://publications.waset.org/abstracts/search?q=Andi%20Setiawan"> Andi Setiawan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Indonesia placed in sixth rank total Acute Respiratory Infection (ARI) patient in the world and Riau as one of the province with the highest number of people with respiratory infection in Indonesia reached 37 thousand people. Usually society using a mask as prevention action. Unfortunately the commercial mouth mask only can work maximum for 4 hours and the pores are too large to filter out microorganisms and viruses carried by infectious droplets nucleated 1-5 μm. On the other hand, Indonesia is rich with Titanium dioxide (TiO2) and purple sweet potato anthocyanin pigment. Therefore, offered Bio-nano-mask which is a antimicrobial and antiviral mouth mask with Nano-TiO2 coating and purple sweet potato anthocyanins utilization as an effective solution to high ARI patients in Riau, which has the advantage of the mask surface can’t be attached by infectious droplets, self-cleaning and have anthocyanins biosensors that give visual response can be understood easily by the general public in the form of a mask color change from blue/purple to pink when acid levels increase. Acid level is an indicator of microorganisms accumulation in the mouth and surrounding areas. Bio-nano mask making process begins with the preparation (design, Nano-TiO2 liquid preparation, anthocyanins biosensors manufacture) and then superimposing the Nano-TiO2 on the outer surface of spunbond color using a sprayer, then superimposing anthocyanins biosensors film on the Meltdown surface, making bio nano-mask and it pack.

In the fabrication process, Photovoltaic’s (PV) performance are tested in standard test conditions (STC). It specifies a module temperature of 25°C, an irradiance of 1000 W/ m² with an air mass 1.5 (AM1.5) spectrum and zero wind speed. Thus, the results of the performance testing of PV at STC conditions cannot fully represent the performance of PV in the tropics. For example Indonesia, which has a temperature of 20-40°C. In this paper, the effect of temperature on the choice of the 5 kW AC inverter topology on the PV system such as the Central Inverter, String Inverter and AC-Module specifically for the tropics will be discussed. The proper inverter topology can be determined by analysis of the effect of temperature and irradiation on the PV panel. The effect of temperature and irradiation will be represented in the characteristics of I-V and P-V curves. PV’s characteristics on high temperature would be analyzed using Solar panel modeling through MATLAB Simulink based on mathematical equations that form Solar panel’s characteristic curve. Based on PV simulation, it is known then that temperature coefficients of short circuit current (ISC), open circuit voltage (VOC), and maximum output power (PMAX) consecutively as high as 0.56%/oC, -0.31%/oC and -0.4%/oC. Those coefficients can be used to calculate PV’s electrical parameters such as ISC, VOC, and PMAX in certain earth’s surface’s certain point. Then, from the parameters, the utility of the 5 kW AC inverter system can be determined. As the result, for tropical area, string inverter topology has the highest utility rates with 98, 80 %. On the other hand, central inverter and AC-Module Topology has utility rates of 92.69 % and 87.7 % eventually. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Photovoltaic" title="Photovoltaic">Photovoltaic</a>, <a href="https://publications.waset.org/abstracts/search?q=PV-Inverter%20Configuration" title=" PV-Inverter Configuration"> PV-Inverter Configuration</a>, <a href="https://publications.waset.org/abstracts/search?q=PV%20Modeling" title=" PV Modeling"> PV Modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=Solar%20Panel%20Characteristics." title=" Solar Panel Characteristics."> Solar Panel Characteristics.</a> </p> <a href="https://publications.waset.org/abstracts/39210/analysis-on-solar-panel-performance-and-pv-inverter-configuration-for-tropical-region" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39210.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">379</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> Raman Scattering Broadband Spectrum Generation in Compact Yb-Doped Fiber Laser</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yanrong%20Song">Yanrong Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Zikai%20Dong"> Zikai Dong</a>, <a href="https://publications.waset.org/abstracts/search?q=Runqin%20Xu"> Runqin Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinrong%20Tian"> Jinrong Tian</a>, <a href="https://publications.waset.org/abstracts/search?q=Kexuan%20Li"> Kexuan Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nonlinear polarization rotation (NPR) technique has become one of the main techniques to achieve mode-locked fiber lasers for its compactness, implementation, and low cost. In this paper, we demonstrate a compact mode-locked Yb-doped fiber laser based on NPR technique in the all normal dispersion (ANDi) regime. In the laser cavity, there are no physical filter and polarization controller in laser cavity. Mode-locked pulse train is achieved in ANDi regime based on NPR technique. The fiber birefringence induced filtering effect is the mainly reason for mode-locking. After that, an extra 20 m long single-mode fiber is inserted in two different positions, dissipative soliton operation and noise like pulse operations are achieved correspondingly. The nonlinear effect is obviously enhanced in the noise like pulse regime and broadband spectrum generated owing to enhanced stimulated Raman scattering effect. When the pump power is 210 mW, the central wavelength is 1030 nm, and the corresponding 1st order Raman scattering stokes wave generates and locates at 1075 nm. When the pump power is 370 mW, the 1st and 2nd order Raman scattering stokes wave generate and locate at 1080 nm, 1126 nm respectively. When the pump power is 600 mW, the Raman continuum is generated with cascaded multi-order stokes waves, and the spectrum extends to 1188 nm. The total flat spectrum is from 1000nm to 1200nm. The maximum output average power and pulse energy are 18.0W and 14.75nJ, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fiber%20laser" title="fiber laser">fiber laser</a>, <a href="https://publications.waset.org/abstracts/search?q=mode-locking" title=" mode-locking"> mode-locking</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20polarization%20rotation" title=" nonlinear polarization rotation"> nonlinear polarization rotation</a>, <a href="https://publications.waset.org/abstracts/search?q=Raman%20scattering" title=" Raman scattering"> Raman scattering</a> </p> <a href="https://publications.waset.org/abstracts/74790/raman-scattering-broadband-spectrum-generation-in-compact-yb-doped-fiber-laser" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74790.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">221</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> Fast-Forward Problem in Asymmetric Double-Well Potential</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iwan%20Setiawan">Iwan Setiawan</a>, <a href="https://publications.waset.org/abstracts/search?q=Bobby%20Eka%20Gunara"> Bobby Eka Gunara</a>, <a href="https://publications.waset.org/abstracts/search?q=Katshuhiro%20Nakamura"> Katshuhiro Nakamura</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The theory to accelerate system on quantum dynamics has been constructed to get the desired wave function on shorter time.

Unfortunately, this conversion process impacts on the depletion of fossil fuel reserves and causes an increase in the amount of CO2 in the atmosphere, disrupting health, ozone depletion, and the greenhouse effect. Solutions have been applied are solar cells, ocean wave power, the wind, water, and so forth. However, low efficiency and complicated treatment led to most people and industry in Indonesia still using fossil fuels. Referring to this Fuel Cell was developed. Fuel Cells are electrochemical technology that continuously converts chemical energy into electrical energy for the fuel and oxidizer are the efficiency is considerably higher than the previous natural source of electrical energy, which is 40-60%. However, Fuel Cells still have some weaknesses in terms of the use of an expensive platinum catalyst which is limited and not environmentally friendly. Because of it, required the simultaneous source of electrical energy and environmentally friendly. On the other hand, Indonesia is a rich country in marine sediments and organic content that is never exhausted. Stacking the organic component can be an alternative energy source continued development of fuel cell is A Microbial Fuel Cell. Microbial Fuel Cells (MFC) is a tool that uses bacteria to generate electricity from organic and non-organic compounds. MFC same tools as usual fuel cell composed of an anode, cathode and electrolyte. Its main advantage is the catalyst in the microbial fuel cell is a microorganism and working conditions carried out in neutral solution, low temperatures, and environmentally friendly than previous fuel cells (Chemistry Fuel Cell). However, when compared to Chemistry Fuel Cell, MFC only have an efficiency of 40%. Therefore, the authors provide a solution in the form of Nano-MFC (Nano Microbial Fuel Cell): Utilization of Carbon Nano Tube to Increase Efficiency of Microbial Fuel Cell Power as an Effective, Efficient and Environmentally Friendly Alternative Energy Source. Nano-MFC has the advantage of an effective, high efficiency, cheap and environmental friendly. Related stakeholders that helped are government ministers, especially Energy Minister, the Institute for Research, as well as the industry as a production executive facilitator. strategic steps undertaken to achieve that begin from conduct preliminary research, then lab scale testing, and dissemination and build cooperation with related parties (MOU), conduct last research and its applications in the field, then do the licensing and production of Nano-MFC on an industrial scale and publications to the public. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CNT" title="CNT">CNT</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=electric" title=" electric"> electric</a>, <a href="https://publications.waset.org/abstracts/search?q=microorganisms" title=" microorganisms"> microorganisms</a>, <a href="https://publications.waset.org/abstracts/search?q=sediment" title=" sediment"> sediment</a> </p> <a href="https://publications.waset.org/abstracts/26712/nano-mfc-nano-microbial-fuel-cell-utilization-of-carbon-nano-tube-to-increase-efficiency-of-microbial-fuel-cell-power-as-an-effective-efficient-and-environmentally-friendly-alternative-energy-sources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26712.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">407</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">43</span> Eco-Nanofiltration Membranes: Nanofiltration Membrane Technology Utilization-Based Fiber Pineapple Leaves Waste as Solutions for Industrial Rubber Liquid Waste Processing and Fertilizer Crisis in Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andi%20Setiawan">Andi Setiawan</a>, <a href="https://publications.waset.org/abstracts/search?q=Annisa%20Ulfah%20Pristya"> Annisa Ulfah Pristya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Indonesian rubber plant area reached 2.9 million hectares with productivity reached 1.38 million. High rubber productivity is directly proportional to the amount of waste produced rubber processing industry. Rubber industry would produce a negative impact on the rubber industry in the form of environmental pollution caused by waste that has not been treated optimally. Rubber industrial wastewater containing high-nitrogen compounds (nitrate and ammonia) and phosphate compounds which cause water pollution and odor problems due to the high ammonia content. On the other hand, demand for NPK fertilizers in Indonesia continues to increase from year to year and in need of ammonia and phosphate as raw material. Based on domestic demand, it takes a year to 400,000 tons of ammonia and Indonesia imports 200,000 tons of ammonia per year valued at IDR 4.2 trillion. As well, the lack of phosphoric acid to be imported from Jordan, Morocco, South Africa, the Philippines, and India as many as 225 thousand tons per year. During this time, the process of wastewater treatment is generally done with a rubber on the tank to contain the waste and then precipitated, filtered and the rest released into the environment. However, this method is inefficient and thus require high energy costs because through many stages before producing clean water that can be discharged into the river. On the other hand, Indonesia has the potential of pineapple fruit can be harvested throughout the year in all of Indonesia. In 2010, production reached 1,406,445 tons of pineapple in Indonesia or about 9.36 percent of the total fruit production in Indonesia. Increased productivity is directly proportional to the amount of pineapple waste pineapple leaves are kept continuous and usually just dumped in the ground or disposed of with other waste at the final disposal. Through Eco-Nanofiltration Membrane-Based Fiber Pineapple leaves Waste so that environmental problems can be solved efficiently. Nanofiltration is a process that uses pressure as a driving force that can be either convection or diffusion of each molecule. Nanofiltration membranes that can split water to nano size so as to separate the waste processed residual economic value that N and P were higher as a raw material for the manufacture of NPK fertilizer to overcome the crisis in Indonesia. The raw materials were used to manufacture Eco-Nanofiltration Membrane is cellulose from pineapple fiber which processed into cellulose acetate which is biodegradable and only requires a change of the membrane every 6 months. Expected output target is Green eco-technology so with nanofiltration membranes not only treat waste rubber industry in an effective, efficient and environmentally friendly but also lowers the cost of waste treatment compared to conventional methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodegradable" title="biodegradable">biodegradable</a>, <a href="https://publications.waset.org/abstracts/search?q=cellulose%20diacetate" title=" cellulose diacetate"> cellulose diacetate</a>, <a href="https://publications.waset.org/abstracts/search?q=fertilizers" title=" fertilizers"> fertilizers</a>, <a href="https://publications.waset.org/abstracts/search?q=pineapple" title=" pineapple"> pineapple</a>, <a href="https://publications.waset.org/abstracts/search?q=rubber" title=" rubber"> rubber</a> </p> <a href="https://publications.waset.org/abstracts/26716/eco-nanofiltration-membranes-nanofiltration-membrane-technology-utilization-based-fiber-pineapple-leaves-waste-as-solutions-for-industrial-rubber-liquid-waste-processing-and-fertilizer-crisis-in-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26716.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">446</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">42</span> Identifying the Sacred in International Relations: A Religion-Based Analysis on Intimacy between Indonesia and Palestine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andi%20Triswoyo">Andi Triswoyo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The sacred has been a dominant influence in the human lives.

These activities pose challenges for identification and formulation of sets of indicators for modeling creative hubs in Bandung to help stakeholders in formulating strategies. This study intends to identify their characteristics. This research was conducted using a qualitative approach comparing three concepts of creative hub categorization and integrating them into a single instrument to analyze 12 selected creative hubs. Our results showed three new functions of creative hubs in Bandung: (1) cultural, (2) retail business, and (3) community network. Results also suggest that creative hubs in Bandung are commonly established for networking and community activities. Another result shows that there was a shifting pattern of creative hubs before the 2000s and after the 2000s, which also creates a hybrid group of creative hubs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=creative%20industry" title="creative industry">creative industry</a>, <a href="https://publications.waset.org/abstracts/search?q=creative%20hubs" title=" creative hubs"> creative hubs</a>, <a href="https://publications.waset.org/abstracts/search?q=Ngariung" title=" Ngariung"> Ngariung</a>, <a href="https://publications.waset.org/abstracts/search?q=Bandung" title=" Bandung"> Bandung</a> </p> <a href="https://publications.waset.org/abstracts/90652/analyzing-the-characteristics-and-shifting-patterns-of-creative-hubs-in-bandung" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90652.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">177</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> Predicting National Football League (NFL) Match with Score-Based System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcho%20Setiawan%20Handok">Marcho Setiawan Handok</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20S.%20Lemma"> Samuel S.

Many injuries and deaths were recorded, some of the victims were PMU students. Consequently, management of the road to eliminate or reduce accidents to a large extend becomes imperative. The main goal of this project are to propose sustainable solutions for the purpose optimizing safety and improving its sight view by designing some appropriate junctions including bridge and tunnel in the critical locations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=management" title="management">management</a>, <a href="https://publications.waset.org/abstracts/search?q=road" title=" road"> road</a>, <a href="https://publications.waset.org/abstracts/search?q=accident" title=" accident"> accident</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic" title=" traffic"> traffic</a>, <a href="https://publications.waset.org/abstracts/search?q=safety" title=" safety"> safety</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable" title=" sustainable"> sustainable</a>, <a href="https://publications.waset.org/abstracts/search?q=solutions" title=" solutions"> solutions</a> </p> <a href="https://publications.waset.org/abstracts/10182/management-of-al-khaldiyah-road-al-khobar-in-order-to-optimize-safety-and-improve-sight-view" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10182.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">449</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> Dynamical Heterogeneity and Aging in Turbulence with a Nambu-Goldstone Mode</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fahrudin%20Nugroho">Fahrudin Nugroho</a>, <a href="https://publications.waset.org/abstracts/search?q=Halim%20Hamadi"> Halim Hamadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusril%20Yusuf"> Yusril Yusuf</a>, <a href="https://publications.waset.org/abstracts/search?q=Pekik%20Nurwantoro"> Pekik Nurwantoro</a>, <a href="https://publications.waset.org/abstracts/search?q=Ari%20Setiawan"> Ari Setiawan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoshiki%20Hidaka"> Yoshiki Hidaka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We investigate the Nikolaevskiy equation numerically using exponential time differencing method and pseudo-spectral method. This equation develops a long-wavelength modulation that behaves as a Nambu–Goldstone mode, and short-wavelength instability and exhibit turbulence. Using the autocorrelation analysis, the statistical properties of the turbulence governed by the equation are investigated. The autocorrelation then has been fitted with The Kohlrausch– Williams–Watts (KWW) expression. By varying the control parameter, we show a transition from compressed to stretched exponential for the auto-correlation function of Nikolaevskiy turbulence. The compressed exponential is an indicator of the existence of dynamical heterogeneity while the stretched indicates aging process.

In some locations, such as ESA platform, gas trap is mainly caused by the occurrence of flash gas phenomenon which is known as mechanical-physical separation process of multiphase flow. Consequently, the presence of gas trap at main oil line would accumulate on certain areas result in a reduced oil stream throughout the pipeline. Any presence of discrete gaseous along continuous oil flow represents a unique flow condition under certain specific volume fraction and velocity field. From gas lift source, a benefit line is used as a motive flow for ejector which is designed to generate a syphon effect to minimize the gas trap phenomenon. Therefore, the ejector’s exhaust stream will flow to the designated point without interfering other systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diffuser" title="diffuser">diffuser</a>, <a href="https://publications.waset.org/abstracts/search?q=ejector" title=" ejector"> ejector</a>, <a href="https://publications.waset.org/abstracts/search?q=flow" title=" flow"> flow</a>, <a href="https://publications.waset.org/abstracts/search?q=fluent" title=" fluent"> fluent</a> </p> <a href="https://publications.waset.org/abstracts/38424/production-optimization-through-ejector-installation-at-esa-platform-offshore-north-west-java-field" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38424.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">435</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> 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.

In order to create a breakthrough which can bring about more positive advancements in the learning process, a Focus Group Discussion (FGD) is being offered and implemented in certain classes. Interestingly, FGD is frequently used in the social-business inquiries such as for recruiting employees. It is then interesting to investigate FGD when it is implemented in the educational scope, especially in the Sociolinguistics class which regarded as one of the most arduous subjects in this study program. Thus, this study focused on how FGD enhances students Sociolinguistics mastery. In response to that, a quantitative survey research was conducted in which observation, questionnaire, and interview (triangulation method) became the instruments. The respondents of this study were 29 sixth-semester students who take Sociolinguistics of ELESP, Sanata Dharma University in 2017. The findings indicated that FGD could help students in enhancing Sociolinguistics mastery. In addition, it also revealed that FGD was exploring students’ logical thinking, English communication skill, and decision-making. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=focus%20group%20discussion" title="focus group discussion">focus group discussion</a>, <a href="https://publications.waset.org/abstracts/search?q=material%20mastery" title=" material mastery"> material mastery</a>, <a href="https://publications.waset.org/abstracts/search?q=sociolinguistics" title=" sociolinguistics"> sociolinguistics</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching%20strategy" title=" teaching strategy"> teaching strategy</a> </p> <a href="https://publications.waset.org/abstracts/78284/focus-group-discussion-fgd-strategy-in-teaching-sociolinguistics-to-enhance-students-mastery-a-survey-research-in-sanata-dharma-elesp-department" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78284.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">29</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">28</span> The Use of Artificial Intelligence to Harmonization in the Lawmaking Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Supriyadi">Supriyadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Andi%20Intan%20Purnamasari"> Andi Intan Purnamasari</a>, <a href="https://publications.waset.org/abstracts/search?q=Aminuddin%20Kasim"> Aminuddin Kasim</a>, <a href="https://publications.waset.org/abstracts/search?q=Sulbadana"> Sulbadana</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Reza"> Mohammad Reza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of the Industrial Revolution Era 4.0 brought a significant influence in the administration of countries in all parts of the world, including Indonesia, not only in the administration and economic sectors but the ways and methods of forming laws should also be adjusted. Until now, the process of making laws carried out by the Parliament with the Government still uses the classical method. The law-making process still uses manual methods, such as typing harmonization of regulations, so that it is not uncommon for errors to occur, such as writing errors, copying articles and so on, things that require a high level of accuracy and relying on inventory and harmonization carried out manually by humans. However, this method often creates several problems due to errors and inaccuracies on the part of officers who harmonize laws after discussion and approval; this has a very serious impact on the system of law formation in Indonesia. The use of artificial intelligence in the process of forming laws seems to be justified and becomes the answer in order to minimize the disharmony of various laws and regulations. This research is normative research using the Legislative Approach and the Conceptual Approach.

There was a decrease in Gross Domestic Product (GDP) contribution level from rank 7 of 4,41% in 2019 to 3,81% in rank 8 in 2020. A decline in the transportation and warehousing business sector contributes to GDP, resulting in oil and gas companies implementing an efficient supply chain strategy to ensure the availability of goods, especially lubricants. Fluctuating demand for lubricants and warehouse service time limits are essential things that are taken into account in determining an efficient route. Add depots points as a solution so that demand for lubricants is fulfilled (not stock out). However, adding a depot will increase operating costs and storage costs. Therefore, it is necessary to optimize the addition of depots using the Capacitated Vehicle Routing Problem with Time Windows (CVRPTW). This research case study was conducted at an oil and gas company that produces lubricants from 2019 to 2021. The study results obtained the optimal route and the addition of a depot with a minimum additional cost.

Providing arrangements not only for legal certainty, but also in the scope of justice and expediency. The three values achieved by law essentially function to bring comfort to each individual in carrying out daily activities. However, it is undeniable that global conditions have changed the orientation of people's lifestyles. Some people want to ensure their existence in the digital world which is popularly known as the metaverse. Some countries even project their city to be a metaverse city. The order of life is no longer limited to the real space, but also to the cyber world. Not infrequently, legal events that occur in the cyber world also force the law to position its position and even prevent crime in cyberspace. Through this research, conceptually it provides a view of the legal position in crime prevention in the Metaverse world. when the law acts to regulate the situation in the virtual world, of course some people will feel disturbed, this is due to the thought that the virtual world is a world in which an avatar can do things that cannot be done in the real world, or can be called a world without boundaries. Therefore, when the law is present to provide boundaries, of course the concept of the virtual world itself becomes no longer a cyber world that is not limited by space and time, it becomes a new order of life. approach, approach, approach, approach, and approach will certainly be the method used in this research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crime" title="crime">crime</a>, <a href="https://publications.waset.org/abstracts/search?q=cyber" title=" cyber"> cyber</a>, <a href="https://publications.waset.org/abstracts/search?q=metaverse" title=" metaverse"> metaverse</a>, <a href="https://publications.waset.org/abstracts/search?q=law" title=" law"> law</a> </p> <a href="https://publications.waset.org/abstracts/148400/the-legal-position-of-criminal-prevention-in-the-metaverse-world" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148400.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">24</span> Medical Aspects, Professionalism, and Bioethics of Anesthesia in Caesarean Section on Self-Request</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nasrudin%20Andi%20Mappaware">Nasrudin Andi Mappaware</a>, <a href="https://publications.waset.org/abstracts/search?q=Muh.%20Wirawan%20Harahap"> Muh.

This study aims to investigate the medical, professional, and bioethical considerations surrounding anesthesia in cesarean sections performed on self-request without medical indications. We report the case of a 27-year-old woman, G1P0A0 gravid 38 weeks, admitted to the hospital for a planned cesarean section on request for the reason that she could not tolerate pain and requested on a date that corresponded to the date and month of her mother's birth. Cesarean section on patient request fulfills the principle of autonomy, which states that patients have the right to themselves. However, this medical procedure is still considered no safer and riskier even though medical technology has developed rapidly. Furthermore, anesthesia during cesarean section at self-request without medical indications is a dilemma for anesthesiologists considering the risks and complications of anesthesia for both the fetus and the mother. The trend in increasing the number of cesarean sections is influenced by patient reasons such as not being able to tolerate pain, trust factors, and worry about damage to the birth canal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anesthesia" title="anesthesia">anesthesia</a>, <a href="https://publications.waset.org/abstracts/search?q=bioethics" title=" bioethics"> bioethics</a>, <a href="https://publications.waset.org/abstracts/search?q=cesarean%20section" title=" cesarean section"> cesarean section</a>, <a href="https://publications.waset.org/abstracts/search?q=self-request" title=" self-request"> self-request</a>, <a href="https://publications.waset.org/abstracts/search?q=professionalism" title=" professionalism"> professionalism</a> </p> <a href="https://publications.waset.org/abstracts/186522/medical-aspects-professionalism-and-bioethics-of-anesthesia-in-caesarean-section-on-self-request" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186522.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">52</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> Correlation of Building Density toward Land Surface Temperature 2018 in Medan City</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andi%20Syahputra">Andi Syahputra</a>, <a href="https://publications.waset.org/abstracts/search?q=R.%20H.%20Jatmiko"> R.

Medan City is one of the largest cities in Indonesia, with a high rate of change from vegetation to developed land. This study aims to identify the relationship between the percentage of building density and land surface temperature in Medan City. Pixel image analysis method is carried out to obtain the value of building density in pixel images of Landsat 8 images with the help of WorldView-2 satellite imagery. The results showed the highest land surface temperature in 2018 of 35, 4°C was found in Medan Perjuangan District, and the lowest was 22.5°C in Medan Belawan District. Building density samples with a density level of 889.17 m were also found in Medan Perjuangan District, while the lowest building density sample was found in Medan Timur District. Linear regression analysis of the effect of building density with land surface temperature obtained a correlation (R) was 0.64, and a coefficient of determination (R²) was 0.411 and modeling of building density based on the LST has a correlation (R), and a coefficient of determination (R²) was 0.72 with The RMSE obtained 0.853. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=land%20surface%20temperature" title="land surface temperature">land surface temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=Landsat" title=" Landsat"> Landsat</a>, <a href="https://publications.waset.org/abstracts/search?q=imagery" title=" imagery"> imagery</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20density" title=" building density"> building density</a>, <a href="https://publications.waset.org/abstracts/search?q=vegetation" title=" vegetation"> vegetation</a>, <a href="https://publications.waset.org/abstracts/search?q=density" title=" density"> density</a> </p> <a href="https://publications.waset.org/abstracts/118783/correlation-of-building-density-toward-land-surface-temperature-2018-in-medan-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118783.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">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Factors Associated to Down Syndrome Causes in Patients of Cytogenetics Laboratory, Faculty of Medicine, Universitas Padjadjaran in 2014─2015</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bremmy%20Laksono">Bremmy Laksono</a>, <a href="https://publications.waset.org/abstracts/search?q=Nurul%20Qomarilla"> Nurul Qomarilla</a>, <a href="https://publications.waset.org/abstracts/search?q=Riksa%20Parikrama"> Riksa Parikrama</a>, <a href="https://publications.waset.org/abstracts/search?q=Dyan%20K.%20Nugrahaeni"> Dyan K.

Maternal age and paternal age, history of radiation are the common risk factors. This study was conducted to observe risk factors which related as causes of Down syndrome. In this case control study using purposive sampling technique, 84 respondents were chosen from Cell Culture and Cytogenetics Laboratory patients in Faculty of Medicine, Universitas Padjadjaran, Indonesia. They were used as study samples and divided into 42 Down syndrome cases and 42 control respondents. This study used univariate and bivariate analysis (chi-square). Samples population were West Java residents, the biggest province in Indonesia in number of population. The results showed maternal age, paternal age, history of radiation exposure and family history were not significantly related to Down syndrome baby. Moreover, all of those factors also did not contribute to the risk of having a child with Down syndrome in patients at Cell Culture and Cytogenetics Laboratory, Faculty of Medicine, Universitas Padjadjaran. Therefore, we should investigate other risk factors of Down syndrome in West Java population. <p class="card-text"><strong>Keywords:</strong> <a
