The widespread use of plastic in the citizen’s life could cause environmental problems. Plastic is synthesis polymer made from the petroleum product which is difficult to decompose naturally in nature. This study reprocess expanded polystyrene and multilayer as raw materials using pyrolysis in fixed bed reactor into fuel oil. The ratios of the raw material of expanded polystyrene and multilayer plastic are 1:0, 9:1, 4:1, 7:3, 3:2, 1:1, 2:3, 3:7, 1:4, 1:9, 0:1 with the raw material mass is 250 gram. The cracking time is 30 minutes and 60 minutes at the temperature cracking of 250°C. This research reveals that the physical properties of the product which are density, viscosity, heat value, and flash point through GC-MS analysis results were aromatic compound. The highest result is the styrene compound at ratio (1: 1) is 44.34%, at ratio (0: 1) is 40.59% and at ratio (1: 0) is 28.56%. The addition of multilayer plastics is able to increase the percentage of styrene but also decrease the percentage of other benzene, that is ethylbenzene.
