The massive increase in the world's population has led to an increase in fuel consumption
in the world. The most popular energy still relies on fossil fuels today, which are depleting the earth's
reserves, so an alternative fuel is needed, namely biodiesel. Biodiesel has the advantages of being
biodegradable, non-poisonous, has low emissions, and is renewable in availability. The biological
materials that can be used as biodiesel are palm oil, coconut oil, and corn oil. In this research, the
three feedstocks were blended into a composition (multi-feedstock biodiesel) which was mixed with
HSD (Pertamina dex) to become B20, B35 and B100 fuels. The fuels were tested on a four-stroke
diesel engine with 1000 watts, 2000 watts and 3000 watts lamp loading with engine speed variations
from 900 rpm to 1050 rpm. From the test results, it was found that the performance results in the
form of power, torque, and generator-specific fuel consumption values were the most optimal, namely
B100 fuel. From this research, the most optimal percentage of fuel mixture is 100% multi-feedstock
biodiesel or pure biodiesel.
