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.

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.

Study of plant ecology in around of Wani Mountain, Buton Utara GamePreserve, South-East Sulawesi, was conducted in April 2004. Two plots each 0,5 ha (50x100m) on 300 and 400 m a.s.l were established. As the result, the forest type is low land primary forest, which inclination land is steep. There were 106 species from 78 genus and 36 families, which dominated by Pometia pinnata, Litsea albayana, Homalium foetidum, Syzygium bordenii, Kjellbergiodendron celebicum, Cleistanthus myrianthus, Orophea celebica and Polyalthia lateriflora. Number of trees noted 452 individual/ha and sapling were 3016 ha/ha. Total Basal Area of trees in two-study site is 29,71 m/ha and distribution stem diameter class were largest between on 10-20 cm.

Macro invertebrate study in Upper Citarum Watershed conducted for a fewtarget, such as understanding some organisms indices and the function in aquatic ecosystem.In this study, besides identified macro invertebrate type also measured some water quality parameter that influence to the exchange of its habitat quality. Water quality laboratory analysis indicates that pressure to macro invertebrate life happened due to the change in environmental quality Upper Citarum Watershed, either by physical impact (erosion) and also chemical impact (domestic, industries and agriculture). To overcome the problem mentioned, environmental monitoring enhancement to be needed, so that calamity of aquatic organism losses can be avoided.

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.

Study on richness, diversity and potential species of plant in two location in the Pegunungan Cyclops Nature Reserve had been conducted. One hundred and fifty species of plant are collected from this area, and 75 species of them are reported as potential species. The largest group of potential species is medicinal plants (35 species) follows by timber (33 species), ornamental plants (22 species), vegetables (16 species), and fruits (10 species). The results of study recommended that buah merah (Pandanus conoideus), matoa (Pometia pinnata) , tongkeu (Aidia racemosa), oi nokom (Parastemon urophyllus), and kayu besi (Instia bijuga) were very important as potential species of plants; and also reported that kreipeh (Saccharum officinarum) is a potential geneticresources of the wild sugar plants in Cagar Alam Pegunungan Cyclops.

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.

During the present time, the coastal area is lack of interested by the farmer as the cultivation site of agriculture plant. It is caused by the problem constraint of land physical character and the climate (particularly, micro climate), so that most confined the kinds of plant may be cultivated. The more narrowed of agriculture area, then optimalizing the use of coastal area for developing agriculture is necessary to conduct, although must throungh various means with an environment reengineering, as climate modification, conservation efforts of land moisture, supplying irrigation water, and etc.So that in the research will be implemented the research on the melon plant cultivation with various treatment.But, these condition of micro climate can be manipulated or reengineered with using simple technology in shape of closed shade, so that can be created an ideal condition for cultivation requirements. The result show that melon plant cultivated under the shade with sprinkler irrigation and drip irrigation gives the highest result that is 325 kg/70 m2 or 4,65 kg/m2, the melon planted under the shade + sprinkler irrigation + mulse the result 272 kg/70 m2 or 3,89 kg/m2, while the lowest result is that planted without using the shade with sprinkler irrigation and drip irrigation : 200 kg/m2 or 2,86 kg/m2.
