Abstract

Bioethanol is one of biomass based alternative energy. Biomass sources that can be used is lignocellulose from wood product waste. Consumption of paper and cardboard, which is one of wood product, of the world in 2015 reach 410,7 million tons. In this research, bioethanol is produced from raw material that is originated from wood product waste such as HVS paper, cardboard, and sawdust. Delignification is done to 50 grams of raw materials, than add 500 mL of H2SO4 10% for 2 hours and 100 °C. Hydrolysis with 5 grams of cellulase enzyme is done with 500 mL of water on pH 4 and 50 °C temperature for 4 hours. Fermentation in this bioethanol production use Saccharomyces cerevisiae with fermentation time variation of 8, 10, and 12 days. Furthermore, there are 2 stages distillation – adsorption process with adsorbent variation, zeolite 4A and silica gel for 60 minutes. Highest result is reached by sawdust raw material, 10 days of fermentation time, and zeolite 4A as adsorbent, with ethanol content 44,78 %.
