Abstract
Tofu is a traditional food for most people in Indonesia. Tofu liquid waste has the characteristics of high levels of BOD and COD. If it is directly discharged into water bodies, it will obviously reduce the carrying capacity of the environment. Then further processing is needed, namely Resin Immobilized Photocatalyst Technology (RIPT). In this study, immobilization of the catalyst against the resin was carried out with the aim of expanding the surface and carrying the catalyst. After obtaining the RIP, it is put into wastewater and the BOD and COD levels of the tofu liquid waste are calculated. Then the resin capacity is calculated in order to determine the resin's ability to absorb ions. The test treatments were carried out 90 times with catalyst volume variants (10gr, 20gr, 30gr), RIP variations (5gr, 10gr, 15gr) and time variants (0, 30, 60, 120, 180 minutes). From the research that has been done, it can be concluded that the capacity of the resin to reduce the highest COD concentration is 0.9523 g/L using a ZnO catalyst and 0.8733 g/L using a TiO2 catalyst. Meanwhile, the highest decrease in BOD concentration was 0.3159 g/L using ZnO and 0.2806 g/L using TiO2. The effluent parameter concentration is directly proportional to the resin capacity. As the sampling time increases, the capacity resin decreases
