- Potency of Bioethanol Production From The Banana Musa sp. Waste. Research about production bioethanol from the banana’s Musa sp. has been done. Production bioethanol from the starch/carbohydrate the banana’s Musa sp. initiated by convertion process of the carbohydrate into glucose. Glucose product then fermented by yeast with variation weight there are; 10, 15, 20 g respectively, then fallowed by destilation and redestilation process to produce the pure ethanol. To analyze the degree of purity of ethanol carried of by HPLC (High Perfomance Liquid Chromatography). The result of the research showed that on variation of yeast 10, 15 and 20 g can produce ethanol are 74.50%, 70.12%, 66.31% respectively
