Description
The purpose of this research is to study the biomass fuel pellets. With cold compressed techniques high pressure. The main raw material used in the experiment are cassava and coffee grounds. Cassava was crushed and coffee grounds is baked and gliding grinded and sieved in the grain size of a 300 - 2000 μm. The samples were mixed with cassava and coffee grounds ratio of 10: 0, 9: 1, 8: 2, 7: 3, 5: 5, 7: 3 and 0:10 and compressed with a compression ratio of 5 , 10 and 15 tons/cm2. The cassava flued pellets sample were studied the properties of calorific value and compressive stregh. Experimental results on the cassava and coffee grounds to test the calorific value with a bomb Calorimeter is 3571.40 and 5236.70 cal / g.
Keywords: Cassava, coffee grounds, fuel pellets , Compressive strength
