    Has been made modifications Clay pottery commonly used as a container of water for household needs. The pottery acts as a top-cut photocatalyst reactor so that the surface area of the sample will be more readily exposed to UV, wherein the inner side of the Pottery is coated with TiO2 sol gel method of split coating technique. TiO2 paste is prepared by dissolving 5 gr of TiO2 (anatase) powder in 20 mL of ethanol. The paste is stirred with a magnetic stirrer for 30 minutes at a rotational speed of 300 rpm for a homogeneous solution. Prepared TiO2 paste is placed on the inner side of the Pottery by split coating the TiO2 paste and flattened with a spatula, this layer is made up to 3 layers. After the coating process, the pottery is allowed to dry in the open air. Then Titania coated pottery is ready for dehydrolysis at 400 ° C for 10 minutes for the organic material to evaporate. The results of crystal structure testing with x-ray diffractometer (XRD) showed that more coatings were done causing the crystal quality of TiO2 thin films would be increase. In addition, more coatings are done causing the crystal size of the TiO2 thin film to increase. The results of test COD and BOD values, showed photocatalyst reactor from clay pottery modification can reduce the content of BOD by 4.45mg / l and COD by 27.20 mg / l. The organic substance and the acidity level of the peat water samples appear to be reduced is indicated by PH 5.7
