The Impact of Adhesive Percentage Variation on Combustion Value of Durian Skin Biomass Waste

Abstract

Development of Medan has an impact on the waste problem with durian skin significantly and certainly needs to resolve immediately. Innovation by technology development is used to process organic waste to become briquette is one of the ways to solve the waste problem with advantage economically as well as reducing unemployement. The technology built is durian skin chopper, rotary bio carbon machine and briquette press with pneumatic system and amount of tapioca adhesive in order to get effective burning promptness (gr/s). Briquette is made by mixing tapioca adhesive respectively 6 %, 9 %, 12 % and 15 % on durin skin biomass carbon in order to get maximum combustion rate (gr/s). The highest combustion rate is 5915 cal/gr (carbon powder is 34 gr and adhesive 6 %) and the lowest combustion rate is 5611 cal/gr (carbon powder is 34 gr and adhesive 14 %). The lowest adhesive value of variation is 6 % with combustion rate is 0.2616 gr/menit while the highest adhesive value is 15 % with combustion rate is 0.27744 gr/menit. The adhesive containing water will impact on combustion rate.
