This paper reveals on the production of biodiesel from waste oil. The production scenario was carried out via esterification and transesterification. As the feedstock of transesterification, the waste oil should be in a good quality with a low content of trash compounds such as free fatty acid (FFA). This study was initiated by an acid treatment for reducing FFA content of waste oil. Thus, it was followed by transesterification under a strong alkali as catalyst at 60°C of reaction temperature. A molar ratio of methanol to oil was determined in excess to maintain the reaction equilibrium. To optimize the applied parameters in this study, response surface methodology (RSM) or design expert application was used. The results showed that the esterification was successfully to minimize FFA of waste oil less than 1.0%, and transesterification was able to produce a maximum quantity of biodiesel at around 85%.
