Pembuatan Biobriket dari Limbah Cangkang Kakao

Abstract

Biobriquette is an alternative energy as fuel substitute which is produced from organic materials or underutilized agricultural waste (biomass). Some types of biomass waste has considerable potential as wood waste, rice husks, straw, bagasse, palm shells, and municipal solid waste. Another untapped potential is the cocoa shell waste. These wastes are not used if it will cause a bad odor and may damage ecosystems. This study aims to see the effect of particle size variations and biobriquette shape to the biobriquette compressive strength produced, quality analysis, and combustion rate of biobriquette. The making of biobriquette used starch as adhesive as much as 50% of the biobriquette weight, variations of biobriquette particle size were 30 mesh and 60 mesh, the shape of biobriquette were hollow cylinder and solid cylinder. The results showed that biobriquette generated met the fuel standards for households. The best biobriquette was hollow cylinder biobriquette with the size of 30 mesh and the resulting calorific value was more than 4000 cal/g. Based on burning test, biobriquette obtained could be used as fuel.
