Pengaruh Konsentrasi Perekat Tepung Tapioka dan Penambahan Kapur dalam Pembuatan Briket Arang Berbahan Baku Pelepah Aren (Arenga pinnata)

Abstract

The demand of renewable energy resources has been increasing in time by time. Briquette is one of the alternative energy resource which is produced from utilization of biomasses. This research aims to obtain a briquette from sugar palm frond, to obtain the effect of concentration of cassava starches as binder and limes as addictive on the quality of briquettes. This research usedthe batch method. Research variabels are the binder concentration of cassava starches in 0%, 10%, 20% and 30% (w/w) and the addiction of limes in 0%, 1%, 3% and 5% (w/w) based on the weight of char powder.Materials are sugar palm (Arenga pinnata) fronds, cassava starches and limes, and the general tools are furnace, briquette printer, oven, moisture analyzer, universal testing machine and bomb calorimeter. Briquetting process was started with sugar palm fronds preparation then they’re carbonized at 350o C for 2 hours. Product of carbonization as a char which was added by a cassava starch’s binder and limes then they’re printed or shaped to be a briquettes. Analysis used was the proximate analysis of the test parameters moisture content, ash content, volatile combustion matter content, carbon content, calorific value and compressive strength. The best briquette is with binder concentration in 0% and addiction of limes in 5% with the calorific value 6502,379 cal/g, 45,56% fixed carbon, 6,44% moisture, 18,00% ash, 30,00% volatile combustion matter and 59,141 kg/cm2 compressive strength.
