TiCl 4 successfully as precursors for synthesised TiO 2 in nanometer-sized through the sol-gel method on the variation of the concentration of root extract of M. Citrifolia and have shown photocatalyst activity to degrade methylene blue with UV radiation in 365 nm. The characteristics of TiO 2 synthesized such as crystalline, size and morphology using SEM. SEM analysis showed that the morphology of TiO 2 synthesized showed the spherical shape in the nanometer-sized. Examination of the energy bandgap using UV-Vis DRS showed a decrease bandgap for TiO 2 synthesized (TiO 2 Merck = 3.2 eV; TiO 2 10x = 3:16 eV; TiO 2 50x = 3.1 eV; TiO 2 100x = 3.08 eV). The best degradation photocatalytic activity is demonstrated by TiO 2 100x until 84.07%. The reaction rate of TiO 2 photocatalytic for the degradation of methylene blue follow a pseudo-second-order reaction model.
