    Petroleum fuel requirement for future always increase but still little alternative energy to make balance. Therefore, it’s important to research alternative energy for fuel substitution of petroleum. PFAD (Palm Fatty Acid Distillate) is raw material that have big potency to produce alternative energy, one of alternative energy is biodiesel. Biodiesel is one of the alternative source substitution to made diesel oil that use reaction of vegetation oil esterification. Esterification is reaction of free fatty acid (FFA) with alcohol to form metil ester (biodiesel) and water. Esterification PFAD use H-Zeolit that preparation of natural zeolites, alcohol that used for esterification reaction is methanol. The change variable of esterification PFAD that use are reaction temperatur ( 600C ; 650C ; 700C) and the mixer speed (100 rpm, 200 rpm, 300 rpm) and for fixed variable are ratio of molar PFAD : methanol is 1:5 and heavy ratio H-Zeolit catalyst is 15 % (basic PFAD). Biodisel which result will be analyse viscosity kinematic, density, cloud point, flash point, and cetane number. This research got highest reaction conversion when temperatur reaction is 650C and the mixer speed is 300 rpm that is 38,37 %.
