Majalaya located in Bandung District is one of the centers of the textile industry in West Java. Generally, waste water discharged into the Cikacembang River. Problems arising from the waste industry disposal consisted of Chemical Oxygen Demand (COD) and Total Suspended Solid (TSS) which are in high concentrations. The purpose of this experiment was to determine the effectiveness of aquatic plants as phytoremediation agent to improve Cikacembang River's water quality. Prior to the experiment, preliminary study conducted by Baseline Point Test for 24 hours. Based on the results of this test is known that the condition Cikacembang River fluctuated, depended on the presence of textile waste and upstream conditions. Phytoremediation experiment conducted in two ways: in Cikacembang River and in the laboratory. In field experiment, plants used were water hyacinth (Eichhornia crassipes). Plants were placed on two nets with 2 x 1 x 1.5 m. Water samples collected at three different points; before the first net, between the nets and after the second net. In this field experiment water samples collected on 0, 3, 5, 7, 14, 21, and 28 day of experiment. The second experiment conducted in the laboratory. In this experiment used three types of aquatic plants, namely; water hyacinth (Eichhornia crassipes), water lettuce (Pistia stratiotes) and kariba weed (Salvinia molesta). Water samples collected on 0, 3, 5, and 7 day of experiment. It was found quite different results from these two experiments. In field experiment there were removal and increase the percentage of contaminants, because the system of water through the plant was continuous. In laboratory experiment, only water weed (Salvinia molesta) which was able to survive and reduce the concentration of pollutants up to the last day of the experiment.
