ANALISIS TEMPURUNG KELAPA SEBAGAI SUMBER ENERGI ALTERNATIF DITINJAU DARI VARIASI PENGUAT

The purpose of this study are to : (1) determine the calorifid value, (2) determine performance efficient coconutshell charcoal briquette with variation of reinforcement material. The research used the experimental method by utilizingthe charcoal briquettes from the coconut shell in review from variation of materials where sand and clay combined to b emolded into briquette form of honeycomb as fuel on stove to boil water. The results of The Calorific values obtained is(B1) 5542 cal/gram, (B2) 5773.333 cal/gram, dan (B3) 5839.333 cal/gram,. The result of combustions tests on the threedifferent types of briqutte that B3 types (codes) of the most superior briquette stoves in terms of the ability to boil asmany as seven times and combustion efficiency 64,15
