Along with the increasing use of fossil fuels, the fossil energy reserves are increasingly depleting. The wealth of vegetable oil sources should be used to move to new renewable energy that is more environmentally friendly, one of them is biomass energy. Biomass energy can come from vegetable oils. Bintaro plants (Cerbera manghas L) contain cerberine poisons and are often wasted in vain. The oil content ranges from 25% to 40% so that it is very potential to be extracted through continuous Screw Pressing technology, the pulp can be directly used as solid fuel (Biopellet) while bintaro seed oil will proceed to the process of making biodiesel Through the transesterification process with a temperature of 65oC. Degumming process is needed before the process of making biodiesel by using weak acids, the use of a solution of citric acid in the degumming process of Bintaro seed oil is more effective. The higher the concentration of the acid solution, the lower the yield of oil produced. The conversion process from triglycerides to methyl ester is obtained by reacting it with a Potassium methoxide catalyst. Based on this study the highest yield of biodiesel was obtained using 0.6% wt KOH, that is, 87.81% with characterization which are still in the value of SNI values (SNI 7182 :2015) . The best quality of biopellet is at a temperature of 210oC with a rotation of 10Hz with a moisture content 2.00%, and the heating value 6689.58 cal / gr. The characterization of it’s still in the range of SNI values (SNI 8021:2014).
