The increase in textile production causes an increase in the amount of liquid waste. This increase can cause pollution to the environment if it’s not treated properly. Therefore, it is necessary to treat textile waste that is effective and efficient to overcome this. This study aimed to investigate the effect of adding graphene to the durability performance of TiO2 layered on cork balls. The floating cork balls cause the TiO2/graphene composite layer can work optimally after exposure to sunlight. The sol-gel method has been successfully carried out by coating the cork ball on TiO2/graphene. The deep coating method was used to deposit TiO2 and graphene on cork balls. Characterization in this study using XRD, FTIR, SEM, and UV-Vis. The diffraction pattern of XRD showed the TiO2 peaks with 6.7 nm crystal size, while graphene was amorphous and does not have a crystal structure. The SEM analysis showed the porosity of TiO2 was 80.3%. The overall absorbance value showed the wavelength at 205 – 230 nm (UV). For comparison of absorbance durability, TiO2 has the working performance at TiO2 (1 Day) at a wavelength of about 230 nm. The degradation results show the absorption of Ultra-Violet (UV) light while the absorbance durability of TiO2/graphene has the lowest peak at 0.1 TiO2/graphene (2 Days) with a wavelength of about 205 nm for a wavelength close to Ultra-Violet (UV) light. Therefore, the longer the irradiation, the decrease in the absorption of UV rays. © 2025 American Institute of Physics Inc.. All rights reserved.
