FITOREMEDIASI FOSFAT DALAM LARUTAN SIMULASI MENGGUNAKAN TANAMAN GENJER (Limnocharis flava), KANGKUNG AIR (Ipomoea aquatica Forsk) DAN ECENG GONDOK (Eichhornia crassipes)

Abstract

The laundry industries increases water pollution in the form of phosphates which is the main substance in detergents. The high phosphate content can lead to eutrophication. The processing waste that is practical and economical way through phytoremediation. The aims of the research is difference to ability of three types of aquatic plants such as yellow velvetleaf (Limnocharis flava), water spinach (Ipomoea aquatica Forsk) and water hyacinth (Eichhornia crassipes). Analysis phosphate concentration reduction every 2 days using simulation phosphate solution with a concentration of 5 ppm. The results showed that the three types of water plants have the ability to lower phosphate concentrations were different, with the percent reduce levels of concentration phosphate to the water hyacinth of 94.77%, yellow velvetleaf 73, 88% and to 28.02% of water spinach.
