Banana peel is waste from banana processing industry which has the potential to produce fermented products. This research investigated the production of bacterial cellulose from banana peel waste with the addition of ethanol. The highest production of bacterial cellulose or nata was obtained during 14 days of fermentation. Nata produced without the addition of ethanol within 7 days of fermentation produced 5.06% of yield, 94 grams of wet weight, 76 grams of dry weight, and 19.15% of moisture content. For 14 days, fermentation produced 6.86% of yield, 132.4 grams of wet weight, 102.9 grams of dry weight, and 22.28% of moisture content. The result showed that longer fermentation time produced higher yield, wet and dry weight, and water content. The addition of 1% ethanol in the nata medium can inhibit the growth of Acetobacter xylinum so that nata cannot be formed. © 2025 Author(s).
