Abstract
Waste in Indonesia reaches 65.2 million tons per year, dominated by organic and inorganic waste. Approximately 36% of the total waste is poorly managed, including 4K1P waste (paper, wood, fabric, rubber, and plastic), which can be quickly burned and turned into RDF briquettes through pyrolysis and paraffin adhesive. These briquettes will use three variations of raw materials: organic, inorganic, and mixed waste. The quality of these briquettes is compared based on calorific value, ash content, moisture content, and the fuel requirement for a 7.5 MW capacity power plant if used as fuel. The initial weight of the raw materials for each briquette is 2 kg, resulting in 10 pieces each of organic, inorganic, and mixed briquettes. Test results indicate that inorganic briquettes have the best quality with a calorific value of 8,075.92 cal/g, moisture content of 1.75%, and ash content of 10.84%, meeting the SNI-01-6235-2000 standard. The minimum fuel requirement for the power plant using RDF briquettes is inorganic briquettes, at 3.05 tons/hour or 26,205.6 tons/year. Inorganic briquettes are of the best quality and require the least fuel for use in power plants.
