Organic pollutants in water are an increasingly prominent problem. Given this challenge, this study reported the high adorptive removal of methylene blue (MB) onto potassium hydroxide (KOH)-activated carbon. To prepare activated carbon, saba banana peel that are local organic waste were carbonized at 400 ° C and activated using various KOH concentrations, e.g.(0,5, 1 and 1,5 M). Physical and microstructural properties of activated carbon were characterized by X-ray diffractometer (XRD), scanning electron microscope (SEM), and Fourier Transform Infrared (FTIR). The efffect of KOH concentrations on the adsorption perfromance of MB on KOH-activated carbon were further investigated. The adsorption process occurred more easily after KOH (1,5 M) of concentration and the adsorption capacity of activated carbon improved by more than 23 %. These results indicate that preparing Banana fruit peels-derived activated carbon using KOH activation is an effective way to reduce pollution and utilize a waste resource.
