Analysis of Water and Ash Content in Biomass Briquettes from Durian Fruit Peel Waste and Sawdust
Keywords:Briquettes, Biomass, Durian Peel Waste, Sawdust, Alternative Fuel
Briquettes are used to convert biomass energy sources into other forms of biomass by compressing them so that their shape becomes even. One of the materials for briquettes uses durian peel waste and sawdust as raw materials using molasses (molasses) as adhesive. The results of this study are to bring briquettes as an alternative fuel with biomass raw materials from durian peel and sawdust using molasses adhesive, which has good quality, so that the community can utilize that. This study aimed to determine the moisture and ash content of biomass briquettes as preliminary studies. The analysis was done with carbonation and drying processes, and the resulting weight was recorded after the procedure can be known. Based on these results, the sample with 20 mesh sieves has the lowest water and ash content percentage, about 1.74% and 0.77%. Then, the sample with 30 mesh sieves has the lowest water and ash content percentage, about 1.87% and 0.78%. This value still meets the SNI 01-6235-2000 standard, where both are a maximum of 8%. Combustion the higher the coal ash content, the lower the calorific value obtained.
