Biomass briquette from Durian skin waste and sawdust.

Utilization of energy from waste, known as waste-to-energy (WtE), is a highly recommended option before waste is landfilled. Currently, the term WtE refers to efforts to create renewable energy from waste, both municipal and other organic waste, such as from industrial or agricultural activities. Recovery of energy from garbage or debris can be made in various ways. Generally used is biomass fuel which has low economic value or is a waste after the product is taken. Briquettes with good quality include a smooth texture, not easy to break, rigid, safe for humans and the environment, and good ignition properties, including easy to ignite, long flame time, and not causing soot; the smoke dissipates slightly, and high calorific value. Based on SNI 01-6235-2000, wood charcoal briquettes can be used as a reference for briquettes that use sawdust. The results of this study were to obtain briquettes as an alternative fuel with biomass raw materials in the form of durian fruit peel and sawdust using molasses adhesive, which has good quality. The study's results were to obtain the effect of the sawdust durian peel waste ratio on briquettes' water and ash content. For combustion, the higher the ash content of coal, the lower the calorific value obtained. For the lowest percentage content of a 20 mesh sieve with a durian skin-to-sawdust ratio of 3:1, it has an ash content of 0.78% and a moisture content of 1.87%. Meanwhile, the ash content of a 30 mesh sieve with a durian skin-to-sawdust ratio of 3:2 has an ash content of 0.77% and a moisture content of 1.74%. [ABSTRACT FROM AUTHOR]
