Clay pottery Has been modifications used as a container of water for household needs. The modified of Clay pottery as photocatalyst reactor so that the surface area of the sample will be more readily exposed by Ultraviolet, the inner side of the Clay pottery is coated with TiO2 sol gel method of split coating technique. The TiO2 paste is prepared by dissolving 5 gr of TiO2 (anatase) powder in 20 mL of ethanol. After the coating process, the Clay pottery is allowed to dry in the open air. Photoreactors are arranged in such a way that a mirror is installed to reflect sunlight appropriately. The results of crystal structure testing with x-ray diffractometer (XRD) showed that more coatings were done causing crystal quality of TiO2 thin films to increase with known anatase crystal structure. Test results of COD and BOD values indicate that photocatalyst reactor from Clay pottery modification can reduce the content of BOD by 4.80mg/l and COD by 30.40 mg/l. The organic substance and the acidity level of the peat water samples appear to be reduced is indicated by PH 6.82.
