Abstract : Xylan extraction from sugarcane bagasse was studied in lab-scale with NaOH and KOH solutions enhanced by
thermal autoclaving and statistical optimization using response surface methodology. The raw sugarcane bagasse sample was
analyzed for chemical components; cellulose, hemicellulose and lignin of 49.9, 28.6% and 21.5%, respectively. Then the
extraction reaction was individually carried out with NaOH and KOH solutions by using statistical experimental design.
Three independent variables, namely alkali concentration, extraction temperature and extraction time were investigated.
First, NaOH extraction; the maximum experimental extracted xylan of 0.94 g (65.7% of original xylan) was obtained with
NaOH solution concentration of 1.75 M, extraction temperature of 75°C and extraction time of 25 min. While KOH
extraction; the maximum experimental extracted xylan of 0.78 g (54.5% of original xylan) was obtained with KOH solution
concentration of 0.5 M, extraction temperature of 75°C and extraction time of 40 min. The extraction efficiency (%Ee) of
xylan extraction from sugarcane bagasse by NaOH and KOH solutions was 18.8 and 15.6%, respectively.
