This research focuses on the synthesis of NiFe2O4/Chitosan-PVA/ZnO composite as a photocatalyst in tetracycline degradation. ZnO acts as a catalyst and is combined with NiFe2O4 to reduce the band gap of ZnO. Chitosan-PVA in the composite acts as a barrier between ZnO and NiFe2O4 to preventing photodissolenscence. The synthesized composite NiFe2O4/Chitosan-PVA/ZnO is characterized using VSM, XRD, SEM-EDX, and UV-DRS. VSM characterization indicates a saturation magnetization value of 44.46 emu/g for NiFe2O4/Chitosan-PVA/ZnO composite. XRD characterization reveals the highest intensity at an angle of 2 = 33.49 with particle size of 30.26 nm. SEM-EDX characterization displays a surface morphology coated with more uniform grains, with Ni 10.51%, Fe 25.42%, O 17.22%, C 11.81%, and Zn 29.23%. UV-DRS characterization shows a band gap value of 1.59 eV. The optimum decrease in tetracycline concentration occurs at pH 4 with a tetracycline concentration of 20 ppm and a contact time of 120 minutes. The efficiency of tetracycline reduction at optimum conditions is 98.80%. TOC analysis indicates a carbon percentage decrease of 8.68% in the 20 ppm tetracycline solutio
