Abstract

The alternative fuel for diesel engines was increasingly important because of decrease oil reserves and the environmental consequences of exhaust gases from petroleum-fueled engines. Air pollution was serious environmental problem around the world from CO2 pollution and other particles. Because it was a clean alternative fuel a growing number of requests. Sources of biodiesel fuel derived from vegetable oils is the potential as a replacement for conventional diesel fuel. Biodiesel was an alternative fuel from renewable resources and environmentally benefits. One was to process the rubber seed oil into biodiesel. Rubber seeds to be very potential biodiesel feedstock because of rubber seed oil contains 40-50% fat of dry matter and the availability of rubber seeds are very high in Indonesia.The research was prepared characterization of rubber seed oil determining chemical properties and the FFA decreased. The rubber seed shell was opened to be taken and pressed to take the oil. Rubber seed oil tested its chemical and physical properties. When FFA was obtained over 2% reduction was carried out by esterification with H2SO4 catalyst. Esterification was prepared by with variable time and H2SO4 concentration. The ratio of oil and methanol used 1 : 6. The results showed that chemical properties involve Saponification Value, Iodine Value, Acid Value) of rubber seed oil was a non edible fat so making it feasible for used as raw material for biodiesel with a value of 23.1 % FFA. To decreased the FFA value of the increase concentrations of H2SO4 that FFA value was decreased, the optimum concentrations of H2SO4 was 4 N with a value of FFA = 4.6%.
