RANCANG BANGUN ALAT PENCETAK BRIKET SISTEM HIDROLIK DAN KOMPOR BRIKET (Analisa Perbaikan Tekstur dan Karakteristik Biobriket Dari Arang Kayu Gelam)

Fossil fuels are non-renewable energy resources and resulted in the depletion of fossil fuel reserves on earth. Scientists in the world give solutions to make fossil fuel alternatives. Biomass briquette is one alternative fuel that derived from biomass. The purpose of this study was to determine the type of adhesive, the adhesive composition and the best pressure to make biomass briquette from gelam wood charcoal with adhesive starch and clay and quality compared with existing quality standards. In this study carried with two types of adhesives that are adhesive starch and clay with variation of the adhesive composition of 5%, 10% and 15% each, as well as variations in pressure of 320 psi, 360 psi and 400 psi. The mixture is molded into briquettes are then tested to determine the calorific value, biomass briquette flame test, density, proximate analysis, and drop test. The result showed that the best composition biomass briquette is a sample with 10% starch adhesive and pressure 400 psi. In this composition, calorific value that was produced is 7570.16 cal / gram, 2.68212% water content, the density of 0.5967257 g / cm3, a flame of fire beginning to arise 5.08 seconds, 1 liter boiling water 7.03 minutes, 1.0673783% ash content, 14.039192% volatile matter, fixed carbon 82.222583% and 0.6154205% drop test.. Calorific value and proximate analysis meets the ISO standard No. 1/6235/2000, ESDM No. 47/2006, and density meet commercial quality briquettes, imports, and the United Kingdom
