		abstract={To reduce dependence on fuel oil, the use of bioethanol is encouraged, one of which ? is the second generation. The second generation of bioethanol is produced from ? cellulose, hemicellulose as raw materials and bound by lignin, one of which is ? Kepok banana peel. The process of destroying lignin using chemical delignification ? was carried out by soaking kepok banana peel flour in a 10% NaOH solution with ? a mass ratio of 1:6 (w/v) for 12 hours. The delignified raw materials were then ? tested for their lignocellulosic content using the Chesson Datta method. The ? delignification method with 10% NaOH can decrease the lignin of Kepok banana ? peel by (36,6%), hemicellulose by (11,1%) and increase the cellulose content by ? 62,8%). The result of delignification was continued in the hydrolysis step using HCl ? concentration of 2M, the result was 13.5° brix. The fermentation stage uses a starter ? of baker's yeast with a concentration of 1.4%, urea nutrition with a concentration ? of 1% and a variety of NPK nutrients (0.6%, 0.8%, 1.0%) for 3 days and a substrate ? volume of 150 ml followed by distillation. until it doesn't drip. The best Kepok ? banana peel bioethanol content (6.5%) with a volume of 17ml was obtained at 0.8% ? NPK treatment. The yield produced in this treatment was 17%.}
