Abstract
Abstract The target of increasing the use of renewable fuels is directly proportional to the increasing demand for biodiesel. High demand for biodiesel must be balanced with sufficient availability from producers. One of the factors that influence biodiesel conversion rate is the use of catalysts. The use of sodium teoxide (CH 3 ONa) catalyst in the manufacture of biodiesel can be applied in the process of biodiesel production using induction heating technology. This technology will accelerate the heating process needed in the transesterification reaction. Based on research that has been done, the use of a catalyst concentration of 1% will produce a yield of 86.95% with product quality in accordance with SNI such as density 0.858 gr/cm 3 , viscosity 5.727 cSt, flash point 190°C, and acid number 0.439 mg-KOH/gr.
