The research on photodegradation of congo red dye using MgFe2O4 nanomagnetic has been done. MgFe2O4 nanomagnetic, Mg(NO3)2.6H2O and Fe(NO3)3.9H2O with mole ratio (2:1) were synthesized using coprecipitation method. The success of MgFe2O4 synthesis were characterized using XRD, UV-VIS DRS, SEM-EDX, VSM and FTIR. The photodegradation process of congo red variables including the effect of concentration dye, contact time, and photocatalyst reuse. The result of the XRD MgFe2O4 diffractogram showed a diffraction peak (311) at 2θ = 35.55o with crystal size the 14.38 nm. The UV-VIS DRS characterization obtained an energy band gap of 1.9 eV. Morphological MgFe2O4 showed aggregates with non-uniform size and large pore gaps. The results of EDX MgFe2O4 showed that the constituent elements of Mg, Fe, and O were 7.27%, 62.59% and 22.86%, respectively. The saturation magnetization MgFe2O4 value of 17.78 emu/g. The FTIR spectrum of MgFe2O4 before Mg-O, Fe-O, O-H degradation, after MgFe2O4 degradation showed the addition of C=C, N-H, S=O functional groups. MgFe2O4 nanomagnetic has a pHpzc at pH 8. The best condition for photodegradation of congo red dye on the effect concentration dye of 10 mg/L, contact time of 210 minutes, the percent degradation of 95.58% and 95.88%. The reuse of photocatalyst were carried out three times and the percent degradation of 59.15% and the test result using TOC with concentration of 60 mg/L were 90.62%. The result showed that MgFe2O4 was able to degrade congo red dye.
