Optimizing Diesel Engine Performance Through Comprehensive Analysis of Fuel Utilizing Biodiesel from Ketapang Seed Oil

– Alternative energy sources that can take the place of fossil fuels, like Ketapang seed biodiesel, are needed to meet society's energy crisis demands. Maceration is used to prepare crude oil, and esterification and transesterification are used to create biodiesel. The performance of diesel engines using CN48 fuel and Ketapang seed biodiesel with compositions of B0, B1, B2, and B3 will be covered in the study. The test employs a load of up to 3000 and a rotation variation of up to 2000 RPM. It is evident from the test characteristics and performance test studies that they are connected. Compared to B1, B2, and B3, biodiesel performed better. According to the average calculation on the maximum Specific Fuel Oil Consumption graph, biodiesel fuel has the lowest Specific Fuel Oil Consumption value. B0 fuel provides a lower Specific Fuel Oil Consumption value than B1, B2, and B3 fuels, with a difference. Diesel engine performance employing Ketapang seed biodiesel has been shown to be inferior to biodiesel during this research process.
