Natural zeolite is activated using sulfuric acid (H2SO4) as TiO2 carrier and composites were made by synthesis using inclusion oligocation method. The test material includes characterization with XRD, FTIR and UV-Vis DRS. Characterization of TiO2-zeolite seen in the results of the characteristics using XRD indicates the presence of a spectral peak belonging to rutile in the TiO2-zeolite composite, with a composite size of 29,47 nm. Characterization by FTIR the appearance of absorption at a wave number of 570,93 cm-1 and 2368,59 cm-1 which is the absorption of TiO2. Characterization with UV-Vis DRS showed a decrease in band gap after TiO2 development to 2,9 eV. Photodegradation of ethanol industrial liquid waste was carried out with variations of photodegradation reaction conditions, weight of TiO2-zeolite composite and temperature of ethanol industrial wastewater and temperature at 30, 60, 90 and 120 minutes. The order kinetics of the photodegradation reaction of ethanol industrial liquid waste (vinasse) that occurs follow the second order. After photodegradation, the pH value remained at 4.3, and the levels of COD, BOD and TSS decreased with low photocatalytic activity. The decline that occurs still does not meet the quality standards based on the Regulation of the Minister of Environment of the Republic of Indonesia No. 5 of 2014. %Z Pembimbing: Didik Krisdiyanto, S.Si., M.Sc.
