Indonesia has abundant biomass resources, agricultural waste such as rubber seed shells and castor beans are one of them. One way to process biomass into alternative energy is by pyrolysis method. Pyrolysis is a process in which chemical compounds are broken or the chemical structure of organic matter is broken through a heating process in a reactor without oxygen or with little oxygen. Most pyrolysis uses only one raw material. In this case, to determine the optimal pyrolysis product, observations were made on variations in operating temperature and variations in the ratio of the two materials with operating temperatures of 350°C and 250°C variations in raw material composition (100:0, 75:25, 50:50, 25:75, 0:100), with the addition of natural zeolite catalyst. Product analysis includes % yield of pyrolysis products (bio-char, bio-oil, syngas), proximate analysis of bio-char, calorific value, flash point and CH4 content contained in syngas. The results of this study show the influence of operating temperature variations where the operating temperature of 350°C is most optimal in obtaining % yield of bio-oil and syngas, but for the most optimal operating temperature in obtaining biochar yield is at 250°C
