Eichhornia crassipes is well-known as water hyacinth. Water hyacinth grows rapidly in the nutrient-rich water and high light intensity places. The uncontrollable growth of water hyacinth has caused many negative impacts to the environment. For instance, interrupted water transport and decreased population of aquatic lives. The capacity of utilising water hyacinth is slower than water hyacinth growth and water hyacinth is still considered as a threat to theecosystem. This work was focused on the study of the pharmacological activity and heavy metal content of water hyacinth in Lake Cipondoh, Tangerang. Fresh water hyacinth was pre-treated through oven-drying and milling process. After that, each part of the plant was macerated by using multiple extraction method with 96% ethanol/water and three variations of sample-to-solvent ratios (1:30, 1:50, and 1:75 w/v). The result of the experiment showed thatwater hyacinth leaves produced an extract with lowest IC 50 (55.76 ± 6.73 ppm) compared toother parts. The most optimum solvent used to achieve this result was 96% ethanol/water (1:1 v/v). In order to obtain the lowest antioxidant activity, the sample to solvent ratio used was 1:50 and the heavy metal in the extract was very low. With this result, it was concluded that there is a promising opportunity to apply the water hyacinth growing in Lake Cipondoh, Tangerang as herbal medicine ingredient. Through this utilization, the overall number of water hyacinth in Indonesia can be reduced or at the least be controlled, so that the environmental problem caused by this plant can be minimized.

Introduction: Heavy metal content of aquatic ecosystems is attracting global attention because of the ecological and human health risks associated with high levels of these metals in the environment. Aim: This study investigated the heavy metal content of various compartments of Ologe Lagoon in order to ascertain the safety of the consumption of fish and other resources from this water body. Materials and Methods: Samples were collected between June and November 2015, from the stations on monthly basis. Some physico-chemical parameters (alkalinity, salinity, pH, turbidity and hardness) and the levels of five heavy metals (Zn, Fe, Cu, Cd and Pb) in water, sediment, Eichhornia crassipes and a commercially important fish (Chrysichthys nigrodigitatus) were studied using standard procedures. Results: The ranges of values of the metals in sediment were: Fe (431.10±109.75-2560.33±1101.32 mgkg–1), Zn (3.77±2.55-17.29±5.30 mgkg–1), Cu (7.45±6.55-35.21±33.79mgkg–1), Pb (5.98±2.29-12.89±4.22 mgkg–1) and Cd (0.31±0.31-0.88±0.21 mgkg–1). The concentrations of heavy metals (except Cu) in Eichhornia crassipes have exceeded FEPA and WHO maximum permissible limits. The mean concentrations of heavy metals (except Zn) in Chrysichthys nigrodigitatus were above the limit recommended by FEPA and WHO. Conclusion: The study showed that the metal load in the biota of Ologe Lagoon is increasing and this may be harmful to inhabitance of the community, who depend on the services provided by this aquatic ecosystem. Therefore, efforts should be made by all users of the water bodies especially the industries to treat their wastes before discharging them into these aquatic ecosystems.
