The community's need for fossil fuels (BBM) derived from fossils is increasingly increasing, causing increasingly depletion of oil and gas reserves. According to Dudley (2015), world oil reserves at the end of 2014 amounted to 1700.1 billion barrels, whereas in Indonesia only reserves had proven oil reserves of 3.7 billion barrels and the amount was only 0.2% of the total oil reserves in world. On the other hand, plastic waste material is an appropriate alternative as a starting material for hydrocarbon sources and can be a potential source of hydrocarbons with a hydrogen / carbon ratio that is quite high compared to coal (Antal et al., 2000). The type of plastic waste that is often a problem in various cities in Indonesia is the type of plastic bags (LDPE), this is due to the waste plastic bags sold unsold for sale on the market. From a variety of existing literature, research is still on a laboratory scale so further studies and testing are needed to a larger scale in the form of a prototype. This research also aims to convert plastic bag waste (LDPE) into liquid fuel and perform various analyzes. The reactor temperature is maintained at (140, 150, 160, 170, 180 oC) and the processing time is 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 190 minutes. Pyrolysis Reactor Prototype Unit can be used to convert plastic bag waste (Low Density Polyethylene) (LDPE) into liquid fuel with a yield of 43.77% or 6.9 kg of the total mass of plastic raw material waste of 15.47 kg and processing time the optimal is 180 minutes with a heating value of 19750 Btu / lb.
