In 2020, Indonesia Government through the Ministerial Regulation of Energy and Mineral Resources No. 12 Year 2015 obligates the use of 30% biodiesel mixed diesel fuel (B30) for various sectors including the power generation sector. The obligation potentially affects the performance of oil-fired power plants (PLTD) and gas engine power plants (PLTMG) that are common power plant technologies used by the State-owned Electricity Company (PLN) in remote and disadvantaged areas. The objective of this study is to estimate effects of B30 usage on performance and emissions of PLTD and PLTMG. We compare performance and emission data of 3 (three) power plants before and after using B30. The results show that the uses of B30 increases spesific fuel consumption (SFC) by 0.009 L/kWh in PLTD and by 0.0071 L/kWh in PLTMG. The uses of B30 will reduce emissions of SO2, CO, and particulate matter, except NOx emission. @en

The increasing community awareness of environmental and social issues has ushered in demands for biofuel production companies to focus on sustainability, where they are expected to not only focus on economic benefits, but also to be environmentally friendly and socially responsible. These companies rely on supply chains that now must pay attention to economic, environmental, and social aspects to operate sustainable supply chains. Making the right calls in any situation is a necessary capability to generate a cleaner and aware supply chain management system within the company, with less increased risk or reduced profits. To develop these capabilities, practitioners need to understand the complexities of the sustainable supply chain and conceptualize the entirety of the supply chain. The objective of this study is to provide a learning medium that could increase corporate awareness in utilizing more eco-friendly regulations. The result of this study is the design of a Serious Simulation Game (SSG) that focuses on the purchasing, production, sales, and finance functions, using case studies of companies that run crude palm oil mills, which was proven effective in helping players understand the concepts and complexities that influence sustainable supply chain management.
