ABSTRACT The objectives of this research were to study the production of biomass briquette by extrusion technique and to investigate its properties in terms of heating value and compressive strength. Raw materials used in this work were the trunk and the branch of Jatropha mixed withthe solid waste (product) from postharvest such as rice husk, bagasse,cassava shell and corncob.The glutinous massused as the binder was made from cassava flour (powder) and molasses. Before mixing with the binder, the raw material was grinded to less than 3 mm. To obtain the high quality ofbriquette, the raw materials were mixed with the binders at the various ratios. The experimental results showed that the heating value increased with an increase in the Jatropha ratio. At the same mixture ratio, the heating value of the briquette from the cassava flour binder was slightly higher than that of the molasses while the compressive strength of the briquette from the cassava flour binder was lower than that of the molasses. However, the heating value and the compressive strength of the briquette from both blinders were quite high for producing biomass briquette. In addition, the heating value was in the range of 11.54 – 15.36 MJ/kgand the compressive strength was in the range of 0.46-2.46 MPa. Keyword: Jatropha , Extrusion , biomass briquette
