The degradation of methylene blue dye has been conducted by Ag@S-TiO2/Ti electrode to increase the plasmon effect on visible light. The addition of silver metal was applied using electrodeposition method. While the S-TiO2 was prepared by sol-gel and immobilization on TiO2/Ti electrode. The results showed that the X-ray diffraction pattern of TiO2/Ti electrode was anatase crystal. Fourier transform infrared analysis in the wavenumber of 1120 and 413 cm -1 indicated the existence of S-O and Ti-O bonds. Supporting by scanning electron microscope and energy dispersive X-ray (SEM-EDX) on Ag@S-TiO2/Ti electrode, the existence of Ag, Ti and S were 2.9, 4.5 and 2.3 KeV, respectively. The plasmon effect identity was active on visible light irradiation confirmed by the photoelectrocatalyst system using linear sweep voltammetry (LSV). Based on the UV-visible spectrophotometer measurement the efficiency of methylene blue degradation was 81.15 % on 0.5 ppm.
