- Biodiesel synthesis has been done from beef tallow through two step, esterification and transesterification reactions. Esterification process is done by using H2SO4 1M as a catalyst, methanol 1:9, temperature of 60-65°C, and for 3 hours. After separated between methanol and trigyceride, then proceed to the process of transesterification. To obtain the optimum reaction conditions then used some transesterification process variables, there are: the weight percentage catalyst of KOH between 0.1, 0.5, 1; 1.5, and 2%, the reaction time of 1-5 hours and the reaction temperature between 50 -70 oC. Optimum conditions of transesterification reaction for the synthesis of biodiesel derived from beef tallow with KOH catalyst is as follows: the weight percentage of 1% KOH catalyst, the reaction time of 3 hours and the reaction temperature of 65 oC. The results of physical testing of biodiesel fuel by ASTM method includes specific density of 0.8675 g/cm3, kinematic viscosity of 4.971 mm2/s, flash point of 134.5°C, pour point of 27°C, the Conradson carbon residue of 0.018%, and the copper corrosion-pieces of 1B.
