Urea (CH₄N₂O) is widely used in agriculture, medicine, and industry; however, excessive accumulation can negatively impact the environment and human health. Therefore, a sensor that is fast, accurate, and stable is required. This study evaluates CuO-TiO₂/C electrodes based on Vulcan carbon, Binchotan carbon, and polyaniline (PANI) modification as urea sensors in 0.1 M NaOH. The electrodes were synthesized through calcination of CuCO₃ and TiO₂ at 450 °C, mixed with carbon and PTFE, and then coated onto a nickel mesh. XRD and SEM results show the formation of CuO (tenorite) and TiO₂ (anatase) phases, with the most compact structure observed in the Vulcan-PANI electrode. CV and LSV tests at urea concentrations of 0.02-0.08 M show that the oxidation current increases with increasing concentration, with the most stable and linear response observed for Vulcan-PANI (CV R² = 0.82; LSV R² = 0.92). These results indicate that the CuO-TiO₂/C Vulcan-PANI electrode has the greatest potential as an electrochemical urea sensor. Keywords : Urea, CuO-TiO₂/C electrode, electrochemical sensor, NaOH electrolyte
