Abstract
Research with the title phytoremediation of Krebet Sugar Factory wastewater using water spinach (Ipomea aquatica) to reduce levels of BOD and COD has been carried out in March-June of 2019. The purpose of the study was to determine the effect of water spinach (Ipomea aquatica) on BOD levels and COD in Krebet Sugar Mill wastewater with phytoremediation technique. The research method used is the posttest-only control group design, which is conducting experiments on liquid waste taken at three points on the waste stream using water spinach (Ipomoea aquatica) with three replications. Based on the results of the study, it was found that the Krebet Sugar Mill wastewater treatment with phytoremediation technique using water spinach plants was able to reduce BOD parameters by 5.49 mg / L at the first point, 2.532 mg / L at the second point, and 5.2 mg / L at the third point, while COD was 7.79 mg / L at the first point, 12.56 mg / L at the second point, and 12.15 mg / L at the third point. The conclusion is the phytoremediation technique using water spinach plants influential to reduce the levels of BOD and COD in liquid waste
