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 su…
