Abstract

This research is motivated by the dwindling energy crisis, while the need is increasing. Biodiesel is an environmentally friendly alternative fuel because exhaust emissions are very low compared to fossil fuels. The process of making biodiesel includes the process of pressing, deguming, esterification, transesterification, and purification then testing the characteristics of biodiesel. This research applies an experimental method using Pertamina's biodiesel fuel process mixed with biodiesel composition B0 and B20. This test was carried out to determine the effect of using B0 and B20 fuel. Biodiesel with a mixture of coconut oil biodiesel against the performance of diesel engines, namely effective power and torque. Based on the test results, in the effective power test, the highest value was obtained on B20 fuel at a load of 300 watts of 325.71 watts while the highest value of effective power for B0 fuel was 310.31 watts at a load of 300 watts because biodiesel has a lower density than biodiesel fuel. The highest torque value is produced when using B20 fuel of 2.48 Nm at 300 watts loading and the highest torque value of B0 fuel of 2.40 Nm at 300 watts loading. This is because two fuels have different characteristics that can affect torque values, differences can also be caused by unstable engines.
