Geographically Bangka Belitung Islands is not far from the equator. The development of human resources and infrastructure for the energy sector is an integral part of regional development efforts. To fulfill the district's energy, we need to look at the potential of renewable energy such as wind power and solar power within the district. This research also provides the potential renewable energy capacity configuration through a simulation.This research used the simulation approach method to map the energy demand over the district and renewable energy available in the region. Energy demand data received from the National Electrical Company (PLN) of Bangka Belitung Province, and potential renewable energy data were obtained from the Ministry of Energy and Mineral Resources of The Republic of Indonesia and the NASA website. Software HOMER is used to analyze electrical energy potential from renewable energy sources.The simulation shows wind energy could provide 0.15 – 0.19 kW and solar power at 3.99 – 4.96 kW/m2/day. The optimum configuration of energy supply consists of 61.4% solar energy and 38.6% wind energy. The hybrid configuration above using the solar photovoltaic (PV) output of 286,981 kWh/year and wind generator output of 180,758 kWh/year and an estimated value of $1,663,598.53 for capital cost, $134,548.34 of operational cost, and cost of energy generated at $0.43/kWh.

The discourse of developing the site has long been announced as a supporting area for Malioboro tourism, and Tugu station developed into TOD (Transit Oriented Development), among others. In 2019, the research, development research aiming to find an area model supporting the realization of the maximum mobility value was carried out in Mangkubumi area to measure mobility levels in the area, and the results of this study found that the rate of mobility and walkability was 76 and 79 respectively.The method used was a simulation of the Urban Modeling Interface (UMI) software to measure the value of mobility in regional models. The research step used area modeling, which was carried out in eight models. After the simulation, the best model with the highest mobility value was selected. The eight models were made based on the four road network patterns of Morlok’s idea (Grid, Spiral, Hexagonal, and Delta), each of which was designed to be two types, namely, type A and type B. Type A was a form of modeling by conducting interventions focused on residential building facilities, and type B was focused on all area building facilities. The finding of this research was that the best road network pattern was the Delta network pattern after intervening in all building facilities and after carrying out land use by placing residential building facilities at the center of the area and placing other building facilities on edge the area. This simulation resulted in a walkability score of 92 and bike-ability of 92. The score is the highest in the walk score ranking level. A value of 92 means that there are walker's paradise, daily business not requiring a car, and biker's paradise, daily affairs done by cycling.","PeriodicalId":280593,"journal":{"name":"ASEAN Journal of Systems Engineering","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114221352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thermal efficiency is vital to analyze the performance of the gas turbine. This research purpose is to analyze the gas turbine's thermal efficiency after performed engine replacement in one of the gas industries in Kutai Kartanegara, East Kalimantan, Indonesia. The data was taken during the period from August 2017 to July 2018, while engine replacement was performed in February 2018. The data were processed to develop simulation models expressing the characteristics of the equipment. The simulation models were then solved simultaneously using the Newton – Raphson Method. A beneficial advantage of Newton Raphson is that it enables to handle a massive number of data and provides faster iteration compare to other methods. Based on the simulation results, the thermal efficiency before performed engine replacement was 23.43% with a net power of 18.109 MW and fuel consumption of 1.640 Kg/s. Meanwhile, the development of thermal efficiency after performed engine replacement was 28.24% with a net power of 18.597 MW and fuel consumption of 1.397 Kg/s. This indicates that after performing engine replacement, the thermal efficiency increased by 4.81% and saved fuel by 0.243 Kg/s.","PeriodicalId":280593,"journal":{"name":"ASEAN Journal of Systems Engineering","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114575012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This map is essential and useful for stakeholders to develop the industry because it provides more directed assistance.In this study, the small and medium industries for processing metal automotive components in Tegal City are used as mapping objects. The technometric method is used to calculate the level of technology contribution they have. The results of this study indicate that the four aspects covering Technoware, Humanware, Infoware, and Orgaware for small and medium-sized automotive component processing industries in Tegal City are in a reasonable range.

Final energy consumption continues to rise along with population and economic growth.Energy planning and development need be done carefully in order to ensure the energy sustainability. This study aim to provide long-term projections in 2012-2025 periods on energy balance, energy demand andsupply based on energy reserves and current condition in order to meet energy elasticity to less than 1. Energy demand projection is calculated based on trend forecasting analysis by LEAP (Long-range Energy Alternatives Planning System).This result shows that the highest energy user sector in Yogyakarta city period 2012-2025 is transportation sector and the highest of energy demand by type is electricity and gasoline.
