Biochar Briquette from Jackfruit Crust: Production, Mechanical and Proximate Properties

In present work, biochar briquettes are produced from jackfruit crust. The briquettes have diameter of 30 mm and height of 40 mm. The work aim to investigate effect of particle size on mechanical and proximate properties of the briquettes and to obtain jackfruit briquette that meet SNI Standard (Standard Nasional Indonesia). Particle size variation of jackfruit char are 40 mesh, 60 mesh, and 80 mesh. The result shows the briquettes made from 80 mesh jackfruit char has the best quality in present work and meet the SNI Standard. Its heating value, fixed carbon, volatile matter, water content, and ah content are 5864 cal/gr, 58.401%, 25.065%, 7.981%, and 8.553%, respectively. However, maximum compressive stress of 0.68 N/mm2 is observed in briquette with particle size of 60 mesh.
