Synthesis of Fe3O4, Fe3O4-SiO2 and Fe3O4-SiO2-NiO naomagnetic had been carried out using coprecipitation and solvothermal methods. Fe3O4, Fe3O4-SiO2 and Fe3O4-SiO2-NiO nanomagnets were applied to degrade methylene blue dye. Fe3O4, Fe3O4-SiO2 and Fe3O4-SiO2-NiO nanomagnets were characterized using XRD, SEM-EDS, VSM and DRS. The XRD pattern shows that the sample is composed of Fe3O4, Fe3O4-SiO2 and Fe3O4-SiO2-NiO nanoparticles. The SEM-EDS characterization of Fe3O4 nanomagnetic showed an uneven surface with the constituent elements of Fe and O. Characterization of the SEM-EDS nanomagnetic Fe3O4-SiO2 showed a round and smooth surface with the constituent elements of Fe, Si and O. Characterization of Fe3O4-SiO2-NiO nanomagnetic SEM-EDS showed round and smooth surface with Fe, Si, Ni and O constituent elements. Magnetic saturation value (Ms) of Fe3O4 were measured by VSM obtained a saturation magnetization value of 83.25 emu/g, then decreased to 61.96 emu/g with the addition of SiO2 content and decreased to 53.83 emu/g with the addition of NiO content. DRS characterization showed that the Fe3O4-SiO2 nanomagnetic band gap was 2.33 eV and the Fe3O4-SiO2-NiO band gap decreased to 2.08 eV. Fe3O4-SiO2-NiO nanomagnetic has a pHpzc value at pH 5.2. The best condition for effectiveness at variations in pH by nanomagnetic Fe3O4-SiO2-NiO is at pH 6. The best condition for effectiveness at variations in concentration by nanomagnetic Fe3O4-SiO2-NiO is methylene blue dye with a concentration of 12 mg/L. The best condition of effectiveness on variation of irradiation time by nanomagnetic Fe3O4-SiO2-NiO is 90 minutes duration.
