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