Phytoremediation is the utilization of green plants to remove pollutants from the environment. A central component of this technology is the use of plants as living technologies that provide services in addressing environmental issues. Therefore, based on the hydrological understanding, phytoremediation technology can be used to manage nutrient and water dynamics; It can lead significant improvement in water quality as well as remediation of degraded ecosystem. Laboratory experiment result indicated, seagrass called Gracilaria sp. have the ability in reducing organic substance as total Nitrogen (N-Total) from 1,2 mg / L into 0.4 mg / L in less than 10 hour. The integration of seagrass into pond ecosystem as organic substances phytoremedian of exceeding fish-feed accumulation expected to become an alternative technology for water quality recovery enhancement.

Jangari is an area in Cirata reservoir that was developed for tourism area. Lately, in this area have been developed many cages for fish culture that produce organic waste in huge number. This research was conducted to know the status and dynamics of water quality in Jangari that receive organic waste in huge number.The research revealed that Jangari water body could be cited as an eutrophic water body. This conclusion was due to (i)-the concentrations of phosphorus was always higher than 0,016 mg•l-1P and nitrogen total was always higher than 0,711 mg•l-1N; (ii)-the density of fitoplankton in 25 cm depth was between 36.590•103 and 40.710•103 ind•l—1; whereas in 150 cm depth was between 29.620•103 and 36.370•103 ind•l—1. This phytoplankton community was dominated byCyanophyta (70,9%-78,2%), especially. Microcystis sp and Oscillatoria sp. (iii)-the vanishing point of secchi disc was always smaller than 71 cm. During the research zooplankton was dominated by copepoda, cladocera and rotifera with density fluctuate between 34-394 ind•l—1. The eutrophic status for Jangari, will threaten the sustainable potency for tourism area; and therefore it was suggested to built one management for Cirata reservoir which could be hoped to plan, do and evaluate the development of Cirataappropriate to the potencies and carryng capasity of reservoir.

This study is trying to apply a new method in remediation electrokinetic byinserting conductive solution between cathode and soil to be treated. This is purposed in keeping the pH in low condition and preventing the precipitation of heavy metals in the soil adjacent to the cathode that often happen in the previous electrokinetic methods. Concentration of Pb (C0), period (t), concentration of conductive solution were selected as parameters, both with artificially contaminated sand and naturally contaminated soil experiments. The experiment with natural soil C0 = 975 ppm gave lower efficiency at 32,84% when it compares with sand as the medium, with the experiment in the same condition at 87,68%. Concentration of KCl also influenced theperformance of system which was shown by the increasing in removal efficiency. The double increase of conductive solution concentration does not proportionally increase the flux of Pb. Although desorption in the natural soil take time longer than in the sand the removal efficiency relatively low. This is caused by the immobile state of Pb in the natural soil and the complexity of chemical reaction between heavy metals with surface of soil particle.

The environmental situation of the estuarial ecosystem Teluk Klabat that islocated at the northwestern coastal area of Bangka was evaluated on the basis of the physical, chemical and biological data derived from direct in-situ field survey during the southeast monsoon (dry season). The objective of this study is to understand the environmental characteristics and water quality status of the Teluk Klabat to support fisheries development within this area. The result shows that the sedimentation process at theTeluk Klabat has been ocurred excessively and it caused decreasing of the bathymetry reached only 1 m that is found almost in a whole of the coast line area at the inner side of the Teluk Klabat and it extended up to more than 2.5 km from that coast line. More over, the terrestrial environment seem to have strong effect on the degradation of the water quality at the Teluk Klabat that is shown by high concentration of the nutrient (nitrate, phosphate, silicate) and heavy metal such as Pb and Cd. While chlorophyll-a concentration was also high. It indicates that the Teluk Klabat tend to be eutrophycation.

Town’s area needs both open and green spaces. This is not only for thesake of aesthetical requirement in shaping the town, but also to fulfill theneeds of fresher and cooler air for its inhabitants. Green area is required toaccommodate people social activities, and also to reduce air pollution –particularly in the form of carbon dioxide comes from vehicles. Besidesreducing air temperature, green area also benefit people by producing oxygenand absorbing dust. Green area must be provided adequately in the town, andbe controlled firmly by legislation. By the provision of sufficient and well-distributed green spaces in the town, people will be guaranteed to have suchlower air temperatures, fresher air and better living environment. This may beresulting, whether direct or indirectly, in reducing the consumption of energy inmany sectors in the town. This article discusses the way green space andvegetation are giving benefit to the inhabitants through several aspects asmentioned above.

Development of city and population in Bandung Basin cause the need ofclean water is increasing too. The increasement of groundwater abstraction andthe decreasement of recharge area will disturb the natural water balance in the Bandung Basin. Therefore, recharge area of the Bandung Basin must be protected and conserved. The efforts to protected this area is done with make some regulation and policy to protect and conserved the recharge area and mapping (delineation) recharge area. Generally the regulation is good enough, but this isn’t detail; and monitoring and inforcement in field is still very weak. From the results of the research that were done, the recharge area in Bandung basin is in the northen and southern part of Bandung Basin with elevation more than 750 m. Detil mapping and delineation of recharge area with scale 1 : 100.000 or 1 : 5.000 must be done as soon as possible.
