<![CDATA[Bioethanol derived from cassava has the potential as an alternative energy material because cassava plants contain starch, sugar or cellulose which can be used in the process of making alternative and environmentally friendly fuels. This study aims to make bioethanol from cassava starch. This research method starts from material preparation to the process stage consisting of the fermentation process, distillation process, and the final stage, namely testing ethanol content and adding fuel. 5 kg of cassava is used to produce 98 ml of bioethanol distillation with 16% rendition. The combustion test was carried out to obtain a comparison of the calorific value between the fuel mixture - Bioethanol and fuel -Alcohol, Mixing partalalite - Bioethanol 1: 19 (95% partalaite: 5% Bioethanol) and fuel - Alcohol 1: 19 (95% partalite: 5 % alcohol). The results of the research obtained the calorific value of combustion of the partalalite - alcohol mixture: 11,649.48 kcal/kg, while for the partalalite - bioethanol mixture: 11,486.15 kcal/kg. So that the higher the concentration of ethanol mixed in partalite, the higher the calorific value.]]>
