Abstract

Raw materials used in the lab is rice straw which is the raw material alternative that can be used in the manufacture of pulp because it has a cellulose content is high enough. Pulp is the result of the separation of fibers from fibrous raw materials (wood and non-wood) through various manufacturing processes (mechanical, semi-chemical, chemical). Based on practice that has been made known that the higher levels of a cellulose then the water content and the lower the yield levels, while on the contrary the higher the moisture content and yield levels, the lower levels of a cellulose. In the experiments the cellulose pulping  levels were lowest in experiment 3 is 74.33%% on operating conditions T = 100 ° C, t = 120 min. The things that affect the results of the lab is operating conditions are not well controlled, the presence of impurities, the digester is not functioning properly. Difference variables such as cooking temperature and cooking time is very influential on the lab results. The difference in these variables can serve to determine the optimum operating conditions for good pulping process. Factors that affect the pulping process is the cooking temperature, concentration, consistency, and time.
