Analisis Laju Pembakaran dan Nilai Kalor Briket Campuran Sekam Padi dan Ampas Tebu

Abstract

The purpose of this study was to investigate how variations in the composition of rice husk charcoal and sugarcane baggase charcoal affect the quality of biomass briquettes. The assessment focused on two main parameters namely burning rate and calorific value. The conversion of biomass waste into briquettes is expected to be an environmentally friendly and economically viable alternative energy source. An experimental approach was employed in this research by applying different variation ratios of rice husk charcoal and sugarcane bagasse charcoal at 4:3 (9 grams of rice husk charcoal : 7 grams of sugarcane bagasse charcoal) and 3:4 (7 grams of rice husk charcoal : 9 grams of sugarcane bagasse charcoal). The briquette manufacturing process included raw material carbonization using the pyrolysis method, charcoal pulverization, mixing with tapioca adhesive, molding, drying, as well as burning rate and calorific value testing. The testing data were then analyzed to determine the influence of feedstock composition variations regarding the characteristics observed in biomass briquettes. Burning rate analysis indicated that the 4:3 variation yielded a combustion  rate reachig 0.155 g/minute and combustion time lasting 90 minutes, whereas the 3:4 variation yielded a combustion  rate reachig 0.148 g/minute and combustion time lasting 94 minutes. The calorific value test results showed that the 4:3 variation produced a mean calorific value of 4752.72 cal/g, while the 3:4 variation produced a mean calorific value of 4679.59 cal/g. The findings demonstrated that the raw feedstock composition variations affected the combustion performance and energy content of the briquettes. Further more, the 4:3 variation produced the highest calorific value, whereas the 3:4 variation resulted in a longer burning time. Overall, rice husk charcoal and sugarcane bagasse charcoal have the potential to serve as feedstock in biomass briquettes production as an environmentally friendly sustainable energy resource.
