dc.description.abstractManganese oxide is one of the metal oxides that has been used as a catalyst to degrade various organic wastes. Among manganese oxide catalysts, manganese oxide MnO (manganosite) has not been widely studied and synthesized. In this study using bentonite as a support which aims to increase the catalytic activity of the MnO composite. This study aims to synthesize MnO-bentonite composites with various compositions of 5% and 15% MnO directly and indirectly using the sol-gel method which were then characterized using XRD and BET instruments to determine the crystal size, surface area and pore size of the MnO composite. -bentonite. To see the catalytic activity of the MnO-bentonite composite, we will test and see the degradation efficiency of methylene blue using a UV-Vis spectrophotometer. The results obtained from this research are that the type of MnO-bentonite composite that has good degradation efficiency is the directly synthesized MnO-bentonite composite with a composition of 15% with a mass variation of the composite 0.05 g; methylene blue initial concentration of 50 ppm and 15 mL peroxide volume with a degradation efficiency of 92.92%.en_US
