Preparation of Cu-doped TiO 2 nanoparticles (Cu/TiO 2 ) as antifungal Phytophthorapalmivorahas been carried out. In this study, we did a synthesis of Cu/TiO 2 nanoparticles by the sol-gel method and determine the performance of the modification of Cu/TiO 2 nanoparticles as antifungal agents P. palmivora . The stages of this research include synthesis of Cu/TiO 2 nanoparticles using the sol-gel method, characterization of Cu/TiO 2 nanoparticles using UV-Vis DRS and characterization of Cu/TiO 2 nanoparticles using SEM-EDX, and P. palmivora antifungal activity test. TiO 2 is known to be used as an antifungal agent and to increase photocatalyticactivity, TiO 2 is doped with Cu metal ions to be active in visible light. The results showed that Cu/TiO 2 has a band gap energy of 3.12 eV. Based on the results of SEM-EDX analysis of TiO 2 -Cu nanoparticles confirmed the presence of elements Cu (2.16%), Ti (28.74%) and O (69.10%) with morphological shapes such as irregular spheres. Cu/TiO 2 nanoparticles have a strong ability at concentrations of 0.05% and 2.5% in inhibiting the growth of the fungus P. palmivora . Percent inhibition respectively 60.41% and 75% and at concentrations>3% have activities that can kill P. palmivora fungus.
