“…Bioethanol has the characteristics of being volatile, flammable, soluble in water, non-carcinogenic, and does not have a negative impact on the environment (Ibrahim et al, 2022). Bioethanol has benefits for human consumption as an alcoholic drink (Ansar et al, 2020;Haregu et al, 2023).…”

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.

In the present investigation, the response surface methodology-based central composite design (RSM-CCD) was used to model the potential of improving the solubilization of food waste through surfactant-assisted homogenization pretreatment (SAHP). RSM-CCD models were investigated based on homogenization speed and time for HP, surfactant dosage, and homogenization time at optimized homogenization speed by HP for SAHP input parameters and chemical oxygen demand (COD) solubilization (CODsol) as response parameters. HP optimum condition was 7020 rpm, 9.9 min to attain 11.6% solubilization with 292.8 kJ/kg total solid (TS) specific energy consumption (ESp). On the other hand, 19.9% CODsol was obtained in the SAHP under optimum conditions of 6.3 μl and 3.7 min, with ESp of 116.2 kJ/kg TS, respectively. The CODsol increment and ESp decrease by 176.2 kJ/kg TS indicate the significance of combined pretreatment and synergistic action of surfactant. Eventually, the maximum biomethane generation was found in SAHP as 67 ml/gCOD, higher than that of HP (40 ml/gCOD) and without pretreatment samples (17 ml/gCOD), respectively.
