Abstract

In Indonesia, industrial waste is widely generated from the wood and food industries. The large amount of waste available in this environment has great potential to be reused into renewable energy, such as biomass pellets. Therefore, it is necessary to conduct research in the field of waste engineering technology that can convert waste into renewable biomass energy in the form of pellets. The purpose of this study is to find out which pellets with raw materials have the best combustion quality and to find out the effect of adhesives on the quality of pellet combustion.This research provides the pellet manufacturing process, which begins with the destruction of raw materials from sawdust, bagasse, corncob. The percentage of adhesives used is 10%, 12%, and 15%. Furthermore, the variable composition that has been named P1 to P9 is put into the pellet mold and pressed using the thread press method. The results of pellet printing are characterized by 5 test parameters, namely ash content, moisture content, calorific value, combustion rate, and Thermogravimetric Analysis (TGA). The best results obtained in this study were 15% adhesive P6 where the ratio Sawdust:corn cobs is 50:50, which had a moisture content of 6.4%, ash content of 2.7%, a calorific value of 4282.34 kcal/gram, and a combustion rate of 0.0962 g/minute. The calorific value possessed by this best sample, if converted into electrical energy, yields a yield of 4,980 kWh/kg, or 0.200 kg of pellets needed to get 1 kWh of electricity.
