This research was aimed to evaluate effect of beating value on CMP pulp fiber characteristics, made from Bagasse. Cooking factors in pulping stage were as: cooking temperature 160°C, cooking time 40 min and Sodium Sulphite 15%. PFI mill with different revelation as 2500, 3000, 3500 and 4000 was used for pulp refining. Analysis of variance of fibers was conducted using completely randomized design, then mean values were compared, using Duncan's test. Results showed that between Fiber length and diameter, lumen diameter, fiber wall thickness, before and after refining, were significantly different at the level of 95 percent. Increasing refiner revolution to 3500 caused significantly lower value for fiber characteristics; but by increasing refiner revolution to 4000, was found no significantly different at the level of 95 percent. Optimizing refiner revolution was suggested 3000, with fiber characteristics and pulp freeness 406 CSF.
