Today people in the world face a crude oil crisis. Supply crude oil is decreasing especially in Indonesia where its needs fulfilled by importing many fuel especially diesel fuel from other countries. Biodiesel is one of the best alternative for diesel fuel. Biodiesel is a fuel which is made from renewable sources especially vegetable oils or a fuel which composition is ester methyl from its fatty acids. Indonesia has a great potential in vegetable resources especially palm which has many surplus in production.<p> <br /> <br /> <br /> <br /> <br /> There are many biodiesel production processes in this world like Biox, Lurgi, Energea, and MPOB. Besides that, Indonesia has also another process like in ITB. Biodiesel production process in ITB consist of two stages which called esterification (convert free fatty acids) and transesterification (convert trigliserides). Transesterification step also consist of two steps and every step need 2 hours for reaction time and use 1,5 times molar stoichiometry in total of methanol with KOH as catalyst. Two hours every stages in transesterification still can be decreased. Decrease in reaction time will increase biodiesel production per time.<p> <br /> <br /> <br /> <br /> <br /> Based on the analysis above, the purpose of this research is to find the best information of successful parameters of producing biodiesel but still making a product in the range of biodiesel specification in Indonesia.<p> <br /> <br /> <br /> <br /> <br /> These research will use Crude Palm Oil (CPO) and Refined Bleached Deodorizing Palm Olein (RBDPO) as a crude oil. This research only works on transesterification with temperature varies (50, 60, and 70 degrees C), reaction time every stages (30, 60, and 90 minutes), and total methanol in stage I (1.3, 1.2, 1.1 times total methanol stoichiometry). Biodiesel will be made by these two crude oils and the conversion will be measured by the value of total gliserol and free gliserol in the end of the reaction.
