Substitution of fuel Oil with environmentally friendly fuel alternatives is one solution. Castor oil (Jatropha curcas L) contained in castor seeds can be processed into biodiesel with transesterification process. The most widely used alcohol in the manufacture of biodiesel is methanol. Methanol is made from a material that is not renewable. While ethanol from renewable materials and pure ethanol are expensive. In this study used campurn ethanol to reduce the use of methanol. The purpose of this study is to find out the optimum comparison of methanol-ethanol. The manufacture of biodicells is carried out by a 2-stage process, namely the esterification process and the transesterification process. The esterification process uses HCL catalysts.
