Wood still used as the main raw materials with natural wood supply more than 70%. The pulp industry worldwide always faced a problem on lack of raw material due to deforestation. Corn stalks is an alternative source of non wood fiber for making pulp. This research was investigated the influence variable process with chemi-mechanical pulping of corn stalk toward pulp properties. The variable process were used solid to liquor ratio (8/1; 10/1; and 12/1) and cooking time (2 hour; 3 hour; and 4 hour). The pulping of corn stalk was accelerated in batch reactor with normal boiling temperature. The results showed pulp with yield 53,43 - 58,50%.and lignin 11,35 - 13,91%.. The influence of variable process on the pulp properties was significant. The increased variable process were caused decreased of yield and Indonesia was ranked ninth producers to supplied the pulp industry.
