The research which had been conducted in March-June 2019 had the purpose of determining the effect of water spinach (Ipomoea aquatica) on BOD and COD levels in Krebet Sugar Mill wastewater with phytoremediation technique. The research used the posttest-only control group design. Liquid waste experiments were taken at three points on the waste stream using water spinach (Ipomoea aquatica) with three repetitions. Data analysis using statistical description by comparing each data obtained from the treatments with controls. The results of the study showed that the Krebet Sugar Mill wastewater treatment using water spinach plants (phytoremediation technique) was able to reduce BOD parameters by 5.49 mg/L at the first point; 2.53 mg/L at the second point; and 5.20 mg/L at the third point; while COD parameters 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 of this research is the phytoremediation technique using water spinach plants influential can reduce the levels of BOD and COD in liquid waste. © 2020 American Institute of Physics Inc..
