Ethanol obtained through biomass fermentation with the help of microorganisms is called bioethanol. The aim of this research is to find out how yeast mass and fermentation time affect the amount of ethanol yield and the value of alcohol content produced from simplex pineapple skin. Fermentation was carried out using bread yeast with masses of 10gr, 20gr, and 30gr and fermentation times of 3, 5, and 7 days. The highest yield of ethanol produced from simplex pineapple skin was 8.5% with a yeast mass of 20g over an optimum time of 5 days. Meanwhile, the highest alcohol content is 30% with a yeast mass of 20g at an optimum time of 5 days. This distillation equipment can produce 31% distilled water with an optimum distillation time of 45 minutes at an average temperature of 70°C.
