This study aims to produce a maximum yield of biofuel from catalytic cracking of waste cooking oil catalyst with a Ni / Zeolite. Cracking performed in a stirred batch reactor for 3 hours with a catalyst concentration Ni / Zeolite 1% and N2 flow rate 150 ml / min. Yield maximum of biofuel is obtained at a temperature of 400 0C with catalyst ratio 1/75 amount 67.5%. Cracking results were analyzed by GCMS method. Cracking product is a liquid alkane constituent of the fuel of 75.34% with conversion of 48.97%.otherBiofuelCatalytic CrackingNi / ZeoliteWaste Cooking Oilstudent Paper Post Degree
