AB  - 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.
