The Effect of Palm Shell and Empty Fruit Bunch Composition Ratio on the Quality of Biopellets for Co-firing

Abstract

Agricultural waste resources, such as biomass, can be turned into valuable alternative energy sources. Biomass is critical to achieving renewable energy in Indonesia. The usage of renewable energy sources, such as biofuels (BBN), should be increased because the demand for fossil fuel sources is increasing year after year, and these fuels are limited and expensive. Biomass-derived from palm oil industry waste in the form of palm shells and empty palm oil bunches (EFB) is currently not being utilized optimally. Therefore, efforts need to be made to make palm shell waste and EFB more valuable products. The content in palm shells and EFB can potentially be converted into fuel in the form of biopellets, namely palm shells and EFB with a composition ratio of 100:0, 70:30, 50:50, 30:70 and 0:100. The purpose of this study was to analyze the effect of the ratio of the composition of biomass raw materials on the Quality of Biopellets for Co-firing. The results showed that the composition ratio of 30:70 has a higher calorific value and meets SNI 8951:2020 as co-firing for power plants.
