"Abstrak\r\n\r\nSugarcane bagasse is one of solid waste from sugar factories. It contains\r\nlignocelluloses that can be hydrolyzed into reduced sugar. Objectives of this\r\nstudy were to find out (1) the best condition (alkali concentration, lignin\r\ndegradation time and temperature) of bagasse lignin degradation, and (2) the best\r\nsubstrate concentration and enzymatic incubation time for hydrolyzing baggase\r\nholocelluloses into reduced sugar.\r\nThis study was performed into two phases, namely lignin degradation and\r\nenzymatic hydrolysis. During the former phase, sugarcane bagasse was immersed\r\nin alkali (NaOH, H2O2) solution at a variety of concentrations for a variety of\r\ntimes and temperatures. After degradation, samples were taken and analyzed for\r\ndegree of lignin degradation. During the latter phases, 3.75% - 6.25% baggase\r\nlignocelluloses were hydrolyzed with 10 FPU cellulase enzyme for 0 – 24 hours at\r\npH 4.8, 50oC, and 200 rpm. After hydrolyzation process, samples were taken and\r\nanalyzed for determining their reduced sugar contents. Collected data were\r\nanalyzed descriptively and presented graphycally. Results of this study shown\r\nthat (1) the best condition for lignin degradation (> 99% lignin degraded) was\r\nimmersion of the sugarcane baggase into 1.0 M NaOH solution at 121 oC for 15\r\nminutes, and (2) the best treatment for sugarcane bagasse enzymataic hydrolysis\r\nwas a substrate concentration of 6.25% and a hydrolysis time of 18 hours. The\r\nhydrolysis treatment yielded a reduced sugar content of 19.29g/L and a bagasse\r\ncarbon conversion of 12,4%.\r\nKey words: alkali, bagasse, pretreatment, NaOH, enzymatic hydrolysis."^^ .
