This study aims to determine the effect of adding Cu to the TiO<sub>2</sub> structure. The 1, 3, and 5 Cu with% TiO<sub>2</sub> dissolved in 50 ml of deionized water, and 3 grams of TiO<sub>2</sub> added. The compound is then stirred for 2 hours at 90<sup>o</sup>C and dried in an oven at 110<sup>o</sup>C for 30 minutes. Drying samples were calcined at 500<sup>o</sup>C for 3 hours. Cu-TiO<sub>2</sub> nanocomposites were characterized by XRD, SEM-EDX Mapping, and FTIR. The XRD analysis results show that Cu-TiO<sub>2</sub> nanocomposite has a high level of crystallinity and has an anatase phase structure. The size of TiO<sub>2</sub> crystals decreased with Cu doping and increased from 49.66 nm to 49.68 nm, with an increase in the composition of the doping mass of Cu. The SEM-EDX Mapping results show that all samples tend to clot, and Cu dopants evenly distributed on the surface of TiO<sub>2</sub>. FTIR analysis explained the presence of hydroxyl ions in the sample marked with the appearance of the absorption peak at 1658.78 cm<sup>-1</sup> associated with OH bending of Ti-OH.</p&gt;}, number={1}, journal={Spektra: Jurnal Fisika dan Aplikasinya}, author={La Ode Asmin and Isa, La}, year={2020}, month={Apr.}, pages={21 - 30} }
