Biomass pellets are made from abundant agricultural wastes such as palm oil shells, coconut shells, and teak wood sawdust that are not adequately utilized. This study aims to analyze the characteristics of pellets made from Palm Oil Shell (POS), Coconut Shell (CS), and Teak Wood Sawdust (TWS). This research will combine these three materials with three different compositions when making pellets. The composition of the materials used in the study is 50% POS, 25% CS, 25% TWS (treatment 1); 25% POS, 50% CS, 25% TWS (treatment 2); 25% POS, 25% CS, 50% TWS (treatment 3). Testing of bio pellet characteristics using Indonesia standard wood pellets or SNI 8021-2014. The analysis used ANOVA with a rate of 5% to see the effect of mixtures of materials on pellet characteristics. The test results obtained that a pellet mix of treatment two is the best pellet with a length of 4.68 cm, a diameter of 0.63 cm, moisture content of 10.78%, a density of 0.8 g/cm3. The ash content pellet of 1.1%, volatile matter 73.52%, fixed carbon 25.38%, and calorific value of 18.86 MJ/kg. The results of ANOVA found that the variety of mixtures of materials affects moisture content, density, ash content, volatile content, carbon content but has no effect on the diameter, length, and heat value of bio pellets. It is hoped that the manufacture of pellets that use agricultural waste can increase the value-added of waste and produce good pellet quality. [ABSTRACT FROM AUTHOR] |
