Abstract
The increasing energy demand in Indonesia still heavily relies on coal, a non-renewable resource with adverse environmental impacts. This study aims to analyze the potential of soybean dregs from soy sauce production and sugarcane bagasse as raw materials for biomass briquettes, evaluate briquette characteristics based on composition and particle size variations. The briquettes were produced through carbonization at 500 °C for 60 minutes, mixing with 5% molasses and 5% cassava starch as binders, molding, and drying. The compositions tested were 63%:27%, 45%:45%, and 27%:63% (soybean dregs: sugarcane bagasse) using 80 mesh and 150 mesh particle sizes. Test results indicated all samples met the Indonesian National Standard (SNI 4931:2010) for moisture content (<12%), ash content (<15%), and calorific value (4500–6000 cal/g). The best performance was found in the 27% soybean dregs and 63% sugarcane bagasse composition with a 150 mesh size, yielding 4.20% moisture, 7.46% ash, 23.73% volatile matter, 5948 cal/g calorific value, and a combustion rate of 0.0221 g/min. However, sulfur content (6.83%) and initial CO emissions (up to 1287 ppm) exceeded regulatory thresholds. The study concludes that soybean dregs and sugarcane bagasse have promising potential as alternative, environmentally friendly fuel sources, though emission control remains necessary.
