- Generallay, the paper is made from fiber plants which contained cellulose fibers and hemicellulose usually exist in nature . One of waste that can be processed into paper-making raw material alternative is rice husk and bagasse. The purpose of this research was to know the influence of the composition of the rice husk and bagasse as well as NaOH concentration against pulp that yields produced. The operating conditions for the best produced of the rice husk's and bagasse's fiber by variation of NaOH concentration were also investigated. Dry raw materials on liquor/crop ratio was 15:1 (mL/g) and mixed with 3 to 6% (w/v) NaOH then digested in an autoclave (120 0C; 1 atm) for 60 min. The operating condition which lowest yield production was mixed between the bagasse's and rice husk's fiber with ratio 1:3, 1:2 and 1:1. The NaClO 5.25% (v/v) was added into the mixture as bleaching agent, then pressed and dried as a paper. The lowest rice husk's and bagasse's fiber yield at 5% (w/v) NaOH concentration was obtained about 45.44% and 35.36%. The lowest yield and density at bagasse's and rice husk's fiber loading ratio 1:2 were obtained about 42.28% and 4.26 g/cm3.
