摘要：A study has been conducted to produce bioethanol from cassava. Bioethanol is produced through a fermentation process followed by a three-stage distillation process to obtain bioethanol with an alcohol content of 95%. Furthermore, the bioethanol produced is then mixed with gasoline and then the specific gravity (SG) and calorific value are evaluated. As much as 5, 10, and 20% bioethanol were mixed into gasoline which was then called E10, E15, and E20. The pure bioethanol called E100 was also tested for its physical characteristics. The test indicates that the SG values in all research variables meet the permitted requirements for transportation vehicles except for E100. The calorific value of the mixed fuel does not meet the standards. However, the lower calorific value at E5 can meet the allowable standard but not for E10, E20, and E100.
