This research aims to synthesize composite Fe3O4/kitosan-polivinil alcohol/TiO2 as an effort to overcome tetracycline waste which pollutes the environment. The magnetic nanoparticle material Fe3O4 acts as a magnetic material, chitosan-polyvinyl alcohol as a barrier between Fe3O4 and TiO2 to prevent dissolution effects which can reduce the effectiveness of degradation, and TiO2 is used as a catalyst. The resulting composite Fe3O4/kitosan-polivinil alcohol/TiO2 were characterized using XRD, SEM-EDS, VSM, and UV-VIS DRS. The characterization results of the composite show the highest peak at an angle of 2θ = 25,43° with a crystal size of 28,29 nm. The morphology of composite is heterogeneous with the constituent elements being C (7,69%), N (12,78), O (14,88%), Fe (63,33%) and Ti (1,29%). The saturation magnetization value is 64,24 emu/g, which indicates that the composite is superparamagnetic with a band gap value of 1,38 eV. The pHpzc of the Fe3O4/kitosan-polivinil alkohol/TiO2 composite is found at pH 6,8. The best condition for removal of tetracycline by Fe3O4/kitosan-polivinil alcohol/TiO2 is at pH 2 with a tetracycline concentration of 15 ppm and an time of 70 minutes with an irradiation effective concentration reduction of 94,85%. The results of Total Organic Carbon (TOC) analysis in the 15 ppm tetracycline solution before degradation were 20,3 ppm and after degradation were 5,59 ppm with a percent reduction in carbon content of 72,46%.
