Abundant rice yields abundant fine husks. Rice bran has an oil content that has the potential as a biodiesel material. The synthesis of alkyl esters from vegetable oils can be carried out through an esterification reaction with an acid or alkaline catalyst. The objectives of this study were 1) to find out the yield of extracted rice bran oil, 2) synthesis of methyl esters from rice bran oil through acid catalyst esterification reaction, 3) characterization and to determine the synthesis component of methyl ester and test its potential as biodiesel. Stages in this study, namely 1) extraction of rice bran oil, 2) synthesis of methyl esters from rice bran through esterification reaction, 3) characterization of rice bran methyl ester and its potential test as biodiesel include determination of density, viscosity, refractive index, and test number acid, 4) identification of constituent compounds methyl ester synthesized by GC-MS. The results of research on rice bran oil extraction have a yield of 18.09%. Methyl esters synthesized from rice bran oil through an acid catalyst esterification reaction with a yield of 72.37%. The synthesis of methyl esters into the range of biodiesel quality standards is, density of 0.850 g / mL, viscosity of 4.73 cSt, refractive index of 1.45871, and acid number of 0.76 g KOH / g methyl ester which has the potential as biodiesel. Methyl ester composition of rice bran oil is methyl tetradekanoate (0.38%), methyl hexadecanoate (40.67%), methyl 9-octadecenoate (53.68%), methyl octadecanoate (5.02%), and methyl eicosanoic ( 0.14%).
