dc.description.abstractReject pulp has not been harnessed into value-added products. Utilization of reject pulp containing 85.16% cellulose, 10.33% hemicellulose, lignin-klason 3.15%, 1.16% extractive-EB and 0.20% ash (ash) can be done with the Saccharification and Co- Fermentation unison (SKFS) to be converted into bioethanol. Saccharification process using the enzyme cellulase, xylanase and selobiase and co-fermentation process using the yeast Saccharomyces cerevisiae and Pichia stipitis. The purpose of this study was to determine the pH and the best time to produce bioethanol. This study varying the pH of the initial solution of 4, 4.5 and 5, and the time variation SKFS 24, 36, 48, 60, 72, 84 hours. Tests on samples made with Alkoholmeter. The results showed that the highest concentration of ethanol obtained in the SKFS to 40 g / L at initial pH 5 solution within 48 hours.en_US
