ABSTRACT Biodiesel is an alternative fuel that can be synthesized from vegetable oils or animal fats. In this research, biodiesel was synthesized from rubber seed oil. Rubber seed oil has a high free fatty acid contain, so esterification reaction was using acid catalyst (H2SO4). Esterification reaction was performed using variation weight of catalyst (0.5, 1, and 2% w/w) and reaction time (1,2…
