Liquid fuel from plastic waste polystyrene (PS) with biodiesel co-reactant from used cooking oil was successfully made. This research was conducted using the catalytic cracking method by Pd/Al-MCM-41/ceramic catalyst to produce various types of hydrocarbon fractions. The structure, morphology, chemical bonds and porosity of the catalyst were examined by XRD, SEM-EDX, SEM, Adsorption-desorption N2, FTIR-Pyridine. The product of catalytic cracking were analyzed by Gas Chromatography - Mass Spectroscopy (GC-MS). The results from GC-MS analysis showed that the largest content of the gasoline hydrocarbon fraction (C7-C12). The oil from PS/Kat120 catalytic cracking has the largest gasoline fraction of 85.64%. More gasoline fractions were formed at the time of catalytic cracking for 120 minutes compared to 60 minutes. The liquid fuel produced by catalytic cracking is added by Premium RON 88 and MTBE additives for research on fuel performance using gasoline engines. Physical characteristics in the form of density, flash point, calorific value, and octane number of a mixture of liquid fuels were also examined. The mixture of CPSJ/Kat2 liquid fuel has the highest percentage of thermal efficiency that is 26.33%, density value of 0.7515 g/ml, a flash point of -48.7C, a heating value of 19160.61 kcal k, and an octane number of 95.6. Characteristics of a mixture of liquid fuels produced in accordance with SNI 06-3506-1994. In addition, the characteristics of the liquid fuel produced are also in accordance with the standard of commercial gasoline.
