Abstract
Study this aim for develop and test characteristics briquettes durian skin with variation composition mixture conducted so that obtained briquettes from ingredient 100% durian skin, 100% husk rice, 100% shell coconut, 50% durian skin and 50 % shell coconut, 70% durian skin and 30% shell coconut, 50% durian skin and 50% husk, 70% durian skin and 30% husk, and 30% durian skin and 70% husk. Have testing to variable endurance after dropped from height 180 cm as influence from variation mixture so that from results the test obtained the missing mass by consecutive are 0.1 gr, 10 gr, 15.8 gr, 3.6 gr, 0.3 gr, 0.4 gr, 0.4 gr, 0.4 gr, 0.3 gr, and 0.4 gr. Test time burning by consecutive are 174 minutes , 120 minutes , 502 minutes , 410 minutes , 376 minutes , 406 minutes , 380 minutes , 367 minutes , and 280 minutes . The resulting calorific value consecutive are 105.8 kcal /kg, 124.9 kcal /kg, 135.3 kcal /kg, 38.2 kcal /kg, 121.5 kcal /kg, 59 kcal /kg, 95 kcal /kg, 128.4 kcal /kg, and 128.4 kcal /kg.
