The use of plastic will increase along with the increasing population and increasing technological development. Increased plastic waste is a big problem for life and ecosystems, because plastic is difficult to decompose in the soil and requires a long time to be decomposed. With the problem of the amount of plastic waste that is difficult to describe, it can be done with the pyrolysis method, the pyrolysis method is the process of heating plastic waste using little or no oxygen in it. To improve the pyrolysis oil, the catalyst is added as a catalyst to obtain better pyrolysis oil results. The purpose of this study was to determine the differences in PET (polyethylene terephthalate) and PP (polypropylene) oils, to compare the results of pyrolysis from the use of catalysts and not use catalysts to the viscosity of the oil produced, as well as the effect of heating time on the results of the pyrolysis oil volume. The results of the research showed that most PP plastic catalyst oils were 33 ml or 8.46%, catalyst PET 23 ml or 8.943% and PP oil without catalyst 76 ml or 19.26%, PET without catalyst 65 ml or 17.23%.
