Abstract

Biodiesel is a clean energy biofuel which can be produced from waste cooking oil under transesterification and purification process by dry washing method. Dry washing purification method using hydrate magnesium silicate as a cleaning agent will improve the quality and yield of the biodiesel. This research used Response Surface Methodology with Box Behnken Design (BBD) consisting of 3 independent variables i.e. concentration of hydrate magnesium silicate, temperature and time to find the optimum condition in producing biodiesel yield. The optimum result showed that the biodiesel yield ranged between 85-94.50% where the maximum yield of 94.50% was produced under an adsorbent concentration of 2%, operating temperature of 55 0C and 20 minutes of treatment.
