Abstract
This study aims to determine the ability of water hyacinth, heartshape false pickerelweed, and water lettuce as phytoremediation of chlorine in water; to determine the ability of those plants, as well as to accumulate and translocate chlorine in water, bioconcentration factor (BCF), and translocation factor (TF). The research method was used, namely the experimental design method to find the effect of certain treatments on controlled conditions. The results of the study concluded that water hyacinth (Eicchorniacrassipes (Mart.) Solms), heart shape false pickerelweed (Monochoria vaginalis (Burm.F) Presi), and water lettuce (Pistia stratiotes L.) have the ability as phytoremediating agents for chlorine in water, with absorption respectively 79.58% for water hyacinth, 73.60% heartshape false pickerelweed, and 87.39% for water lettuce. These plantsare hyperaccumulators if the absorption / accumulation rate is at least 1000 ppm of contaminants. Thus, the three types of plants (Eichhorniacrassipes, Monochoria vaginalis, and Pistia stratiotes) can be categorized as hyperaccumulator plants for chlorine because their accumulation levels are respectively 1492.35 ppm (E.crassipes), 1374 ppm (M. vaginalis), and 1631.28 ppm (P. stratiotes).
