Co-Pyrolysis is the process of two or more organic materials undergoing chemical decomposition in the absence of oxygen. The purpose of this research is to determine the effect of syngas products produced from variations in the composition of coal and rubber wood chips and the value of specific energy consumption (SEC). In this research, the composition of raw materials 100;0, 75;25, 50;50, 25;75, 0;100 were carried out. From the research that has been carried out, variations in composition affect the characteristics of the syngas product and the resulting SEC value. From the results of the research, the % yield of syngas increased along with the increase in the composition of rubber wood chips used, the highest % yield of syngas was produced in the composition of 100% rubber wood chips by 46.93%. The optimal CH4 content in syngas is produced in the variation of 25% coal composition: 75% rubber wood chips with CH4 content of 63%. In addition, the highest flame height was produced in the composition variation of 100% rubber wood chips, which was 30 cm. The SEC value produced by the most optimal syngas was obtained in the composition of 100% rubber wood chips at 7.879 kWh/kg.
