PENGARUH KOMPOSISI CAMPURAN KULIT BIJI JARAK DAN KULIT SINGKONG PADA PEMBUATAN BIOBRIKET TERHADAP NILAI KALOR DAN LAMA PEMBAKARAN

Biomass is organic matter derived from both plants and animals. The biomass energy will become the source of alternative energy a substitute for fossil fuels (petroleum). Biomass can be processed and made as fuel alternate as biobriket. Research aims to understand the influence of the composition of substances (skin castor beans and skin cassava) and influence size mesh to get biobriket best, and he knows value heat engine and long burning. This research uses experimental methods, where the object use your skin castor beans and skin cassava and tapioca as adhesive. With variations composition skin castor beans and skin cassava 100:0, 75:25, 50:50, 25:75, 0:100 the size of mesh 30 and 40. The research variation composition and size mesh affect density, the moisture content of, levels of ashes, the heat engine, and long burning. Biobriket qualified the quality of artificial Indonesia is a variant the composition of substances 50% the skin castor + 50% the skin cassava the size of mesh 30 with a value of the water level 2.5%, the ashes 7.69%, value heat engine 5081 kal/gr, and long burning 32 minutes 24 seconds
