Biofuel is one of the solutions and alternative energy sources. This study aims to produce a maximum yield of biofuel from catalytic cracking of waste cooking oil with catalyst Cu / Zeolite. Yield maximum of biofuel is obtained at a temperature of 400 0C with catalyst ratio 1/75 of 62.5%. Cracking results were analyzed by GCMS method. Cracking product is a liquid alkane constituent of the fuel of 69.85% with conversion amount 43.66%.otherBiofuelCatalytic CrackingCu / ZeoliteWaste Cooking Oilstudent Paper Post Degree
