BriquettesSynopsis
Biomass waste and waste can be an alternative energy sources. Utilization of biomass-derived from waste products of forestry and plantation activities as briquettes. Bagasse biomass waste and dry leaves contain cellulose and lignin, affecting the calorific value. This study aimed to determine the effect of time and power of microwave torrefaction on calorific value, moisture content, and ash content. The method used to make briquettes is the microwave torrefaction method. The research flow consists of drying raw materials, size reduction, and the microwave torrefaction process. The torrefaction process is carried out with natural materials, namely bagasse and dry leaves, put in a microwave at a temperature of 230°C to 280°C in a state without air. The research variable used was Microwave power; 80, 400, and 800 W and torrefaction time; 5, 15, and 25 minutes. According to the result, torrefaction time and microwave power affect briquettes' heating value and characteristics
