Abstract

Se’i meat, a traditional smoked meat in East Nusa Tenggara Province of Indonesia, is processed using kusambi wood as biomass fuel. However, this usage poses a threat to kesambi tree sustainability. The study explores varying particle size and adhesive quantity for kesambi leaf biobriquettes. Experimental trials analyze physical and chemical responses of biobriquettes, aiming for high fixed carbon content and calorific value. Results show that the optimal condition for making the bio-briquettes is combination of torrefied kesambi leaf with particle size of 60 mesh and 5% adhesive. This has resulting in their moisture content of 3.37%, ash content of 2.28%, volatile matter of 14.83%, fixed carbon of 79.53%, density of 0.57 g/cm³, calorific value of 15.91 MJ/kg, and total phenolic content of 0.95 mgGAE/g.
