This research conducted synthesizes MnFe2O4/Kitosan-alginate/TiO2 composites as catalysts in the photodegradation of procion red. The optimum conditions were determined using the RSM method with BBD. The VSM characterization results of the composite show Mr value of 16.92 emu/g, Ms value of 45.22 emu/g, Hc value of 2.22 Tesla, and S-shaped hysteresis curve, indicating this composite exhibits superparamagnetic behaviour. The XRD characterization results of the composite was obtained the highest peak at an angle of 2θ = 25.35° with a crystallite size average of 60.47 nm. SEM-EDS characterization results of the composite was obtained heterogeneous morphology and has constituent elements namely Mn (13%), Fe (23%), O (24%), C (10%), N (4%), and Ti (26%). UV-Vis DRS characterization results was obtained a bandgap value of 1,69 eV so that the composite can be used in visible light. Optimization of procion red degradation was conducted using the RSM Method based on a fitted quadratic polynomial model. Optimization condition is obtained at procion red dye concentration of 58 ppm, pH 3, and contact time of 33 minutes with visible irradiation resulting in a degradation efficiency of 97,32%. This degradation efficiency is greater than using the composite without visible irradiation and using visible irradiation only which amounted to 75.76% and 14.24%, respectively.
