<![CDATA[The global energy crisis is driving the need for environmentally friendly alternative energy, one of which is biomass briquettes from coconut shells, rice husks and sawdust. This research designs and tests a biomass briquette printer based on an electric motor with variations in rotation to produce cylindrical and cube-shaped briquettes with a center hole. The tool design was created using SolidWorks, accompanied by stress, displacement and strain simulations, as well as testing at the Mechanical Engineering Laboratory, Nusa Cendana University, Kupang, NTT. The results show a maximum stress of 5.006 × 10⁴ MPa and a maximum displacement of 2.165 × 10⁻⁴ mm, proving the tool is quite strong. 17.3 rpm rotation produces 19 complete briquettes, showing the best efficiency compared to other variations. This tool is effective for supporting sustainable alternative energy production.]]>
