Abstract: Biodiesel production by using conventional base transesterification or other chemical processes is generally selected as an effective way. But besides, an enzymatic process in biodiesel production is more biodegradable and has many advantages compared to the conventional process. The most important advantage in the enzymatic process is a green technology and safe for the environment. In this study, Novozyme 435 was used as immobilized lipase with degummed crude palm oil (as known as Degummed Palm Oil (DPO)) as raw material. The aim of this study was to determine the optimum condition of the enzymatic process in obtaining the maximum yield percentage by using mathematical statistical analysis and designed as Response Surface Methodology (RSM) method. The reaction was performed at various methanol molar ratio to oil, temperature, reaction time and stirring speed. The optimum reaction condition obtained was 8 h of reaction time at 45°C of temperature, a molar ratio of DPO: methanol was 9:1, the amount of enzyme was 20% of the DPO and 150 rpm of stirring speed.
