All Biosorption of Malachite green and Rhodamine B dyes using banana peel ( Musa balbisiana Colla) as a biosorbent has been carried out. The purpose of this study was to determine the effect of pH and concentration for biosorption of Malachite green and Rhodamine B by banana peel biosorbent ( Musa balbisiana Colla). The method used is the batch method. The maximum wavelength of Malachite green is 618 nm and Rhodamine B 555 nm measured by the UV-Vis Spectrophotometer. The results showed that the optimum conditions for Malachite green adsorption occurred at pH 3, a concentration of 100 ppm 8,0662 mg/g. The optimum conditions for Rhodamine B adsorption occurred at pH 3, a concentration of 120 ppm 16,6614 mg/g. The adsorption isotherm of Malachite green with banana peel (Musa balbisiana Colla) biosorbent tends to follow the Freundlich isotherm with a determinant coefficient (R 2 ) of 0.9996 and Rhodamine B 0,9884.
