Abstract

Nowadays, the world energy demand is very high while the fossil energy source decreases continuously.Biobriquette presents as environmentally friendly alternative energy from biomass. One of the potentialresources of biomass for biobriquette is agricultural waste, such as palm kernel shells and coconut shells.The availability of these wastes is abundant but has not been utilized optimally. Thus, biobriquette productioncan solve two problems at once, namely energy and environmental problems. The objective of this study isto determine the optimum mass ratio of palm kernel shell and coconut shell which has the quality in termsof calorific value, and proximate characteristics (moisture content, ash content, volatile substances, andfixed carbon) qualified the SNI (Indonesia National Standard) specification (No. 01-6235-2000) forbiobriquette. The mixing variations of the coconut shell and palm kernel were 100: 0, 75: 25, 50: 50, 25: 75,and 0: 100. The results of the quality analysis have shown that all samples have met all SNI criteria and thesample with 100% kernel composition was the best composition.
