Onggok is a tapioca industrial solid waste with high cellulose content and is abundant that makes onggok an alternative material for coal. The low calorie value of onggok is around 2783 Kcal/kg which requires an effort to increase its calorie value. Increasing the calorie value of onggok by carbonization in the pyrolysis furnace. The study of onggok pyrolysis to improve its calorie value as good as commercial coal needs to be done. In this study, the effect of time and temperature of carbonization to onggok properties was examined. The temperature of carbonization was 300, 350 and 400°C and the carbonization time was 60, 90 and 120 minutes. Calorie value, moisture and ash content of pyrolyzed onggok was analyzed. The results showed that onggok can substitute coal since it has low ash and moisture content. The maximum ash and moisture content were 5.9% and 1.6%, subsequently. The optimal temperature and carbonization time were 350°C and 90 minutes with the calorific value of 6047 Kcal/kg.
