Abstract

This study aimed to assess the quality of rambutan peel biomass pellets as an alternative energy source in accordance with SNI 8675:2018 on Biomass Pellets for Energy, and to examine the performance of a Top-Lit Updraft (TLUD) biomass stove in accordance with SNI 7926:2013 on Biomass Stove Performance. The quality assessment of rambutan peel biomass pellets was conducted using proximate analysis. The amount of bio pellet used is 700 g with the same size. The results indicate that the rambutan peel bio-pellets exhibit a density of 1.43 ± 0.02 g/cm3, a moisture content of 9.72 ± 0.04%, volatile matter of 63.72 ± 0.01%, ash content of 3.32 ± 0.02%, and fixed carbon of 23.22 ± 0.03%, and two parameters that did not meet the standard value, which are calorific value of 16.39 ± 0.005 MJ/kg or 3,915 ± 1.53 kcal/g, and sulfur content of 0.17 ± 0.002%. Furthermore, it also shows that the combustion of rambutan peel biomass pellets in the Top-Lit Updraft (TLUD) biomass stove produced Particulate Matter 2.5 (PM2.5) emission factors of 143.99 ± 33.38 mg/kg, carbon monoxide (CO) of 5.94 ± 1.11 g/kg, and carbon dioxide (CO2) of 134.69 ± 1.92 g/kg, which is not exceed the maximum value attached in SNI 7926: 2013. In general, the combustion characteristics of rambutan peel bio-pellets satisfy the reference standards for biomass furnace performance, except for combustion efficiency. Improvements in moisture content can be achieved through oven drying, while sulfur levels may be reduced by blending rambutan peel with other biomass materials containing lower sulfur concentrations.
