dc.description.abstractCorn stalk is agricultural solid waste which has not been utilized to the optimum. So far only used for fodder and green manure. Corn stalk delignification experiments intended to study the possibility of utilization of corn stalks as an alternative raw material for the pulp industry, as well as to determine the reliability of formic acid as a medium delignification fractionation and corn stalks in the organosolv process. Corn stalk delignification experiment is carried out at a laboratory scale batch. Experimental variables studied, the concentration of formic acid 70; 80; 90% by weight, the reaction time of 0, 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180 minutes and the ratio of liquid-solid 10/1, with a catalyst concentration of 0.2% hydrochloric acid. The experimental results showed that the corn stalks can be used as a pulp with organosolv process and produce pulp yield from 31.88 to 47.01% and from 10 to 14.31% pulp lignin content, which varies according to the condition of the experimental data with the level of compliance with the model exceeds 95% (R-square> 95%). The whole process variables influential in yield and lignin content, and the quality of the resulting pulp pulp industry standards.en_US
