The research on synthesis of composites Kitosan-Al2O3 by the sol-gel methodfor photodegradation of methylene blue has been carriedout.Chitosan-Al2O3 varied by mass ratios (1:1), (1:2) and (1:3). The product were characterized using XRD, UV-DRS and SEM-EDS. The Chitosan-Al2O3 (1:1) composite was chosen as a material for degrading methylene blueby various condition, i.e., effect of pH, contact time and initial concentration of methylene blue.The result of characterization using XRD showed crystal size the Chitosan-Al2O3 (1:1) composites result were 3,17 nm.UV-DRS characterization, The band gap energy is 1,35eV. The morphological condition by SEM of Chitosan-Al2O3 ratio (1:1) showed a spherical shape with a small size, and a porous surface the constituent elements C (4.93%), O (33.31%), Na (13.92%), Al (45.59%) dan Zn (2.24%).The degradation process showed the effective condition were pH 10 and contact time of 200 minutes. The optimum concentration of methylene blue at 20 ppm with percent effectivity of concentration reduction methylene blue i.e. 79.35% and the result of TOC analysis i.e. 22,36%.
