Abstract
Abstract. Oil Palm Empty Bunches (OPEFB) are agroindustrial wastes that contain cellulose so that they can be used as raw material for pulping. The process of pulping from formacell OPEFB produces pulp with a dark color that requires a bleaching or bleaching process. The purpose of this study was to determine the effect of bleaching time using H2O2 with a concentration of 35% in acetic acid media on the characteristics of pulp from OPEFB which was cooked using the formacell process. The bleaching time used was 0.5, 1, 1.5, 2 and 2.5 hours using 80oC cooking temperature. The study was repeated 3 times. The results showed that the best treatment occurred at the bleaching time for 2 hours which produced a yield of 79.6%, cellulose 51.08%, permanganate number 6.8 and the score for color was 4.5 (white).
