The increasing use of LDPE (Low Density Polyethylene) plastic bags in daily life has led to an increase in plastic bag waste and its negative impacts. This study aims to synthesize and characterize pyrolysis oil from LDPE plastic bag waste using a simple batch reactor. LDPE plastic bag waste was synthesized in a simple pyrolysis reactor using fuel from LPG (Liquified Petroleum Gas) gas operated at 150oC and atmospheric pressure for 55 min. The results showed that the pyrolysis oil produced was 184 ml with a process yield of 36.75%. The pyrolysis oil has a pH of 5, yellow color, pungent odor typical of aromatics, density of 786 kg/m3 and viscosity of 0.75 cP. The FTIR test results indicate that the pyrolysis oil contains alkane and alkene compounds whose density and viscosity quality are superior to kerosene and close to the quality of premium oil, so it can be used as an alternative fuel.
