Hydrocracking of LDPE plastics into fuels over bi-functional catalysts was systematically studied. The natural zeolite from Sukabumi, Indonesia was refluxed in HCl 6N for 30 minutes and dried in an oven, produced the activated natural zeolite (Z). For bi-functional catalysts, Ni, Ni-Mo, Co and Co-Mo metals were loaded into the activated natural zeolite respectively to increase the activity and selectivity for hydrocracking process. The catalyst samples were heated in a microwave and done the reduction by hydrogen gas stream, produced Ni/Z, Ni-Mo/Z, Co/Z and Co-Mo/Z. Hydrocracking process was carried out effectively at 350 °C with 20 mL/minutes of hydrogen flow rate for 1 hour of reaction time. Conversion of LDPE plastic waste over Co-Mo/Z at 350 °C produced the higher selectivity of gasoline, reached 71.49%. According the GCMS data, liquid yield consisted of hydrocarbon compound with atom chain of C8 until C16 that indicate the fuel chemical structure, such as paraffins, olefins and naphthenes. The conversion of plastic waste into fuel is expected to reduce the environmental pollution, support the use of soil, and increase the energy storage.
