The rapid growth of population in developing country causes environmental contamination by increasing significantly pollution load in  river and other water body. It needs efficient and effective strategy to overcome contamination in certain areas. Technical identification of pollution source and its influence to environmental quality is important to should be known and socialized to community. Land use to is important to get  priority  and should be  managed consistently environmentally sound, beside solid waste and domestic wastewater. Law enforcement also should be applied, especially to company or industry which significantly gives contribution to environmental degradation. Environmental restoration need fund, so government as regulator need partner  from private to overcome environmental problem. Environmentally based industries and services is needed to be developed as government counterpart, but up to now the development of them retarded caused by non competitive interest of commercial bank. Environmental fund should be collected from polluter through regulated mechanism and In the next future  environmental bank should possible manage the fund and finance environmental industry and services to overcome environmental pollution, in this case government act as regulator only.Key words : water polution, management, water resources, strategies

Solid waste has become a problem for large and small cities, as they relate to environmental sanitation and health, as well as aesthetic issues. High intensity of rainfall influence  in a high solubility results of decomposition of waste in both TPS and TPA, brought the flow of water and water soak to soil or water flow to the public drainage. Law Number 8 Year 2007 on waste management require sanitary landfill technology. Currently most of the TPA are still not meet the full construction of sanitary landfill and need to be supported by the application of the 3R (Reduced, Reused, Recycle) program in solidwaste. Processing  waste liquid  derived from the leachate (seepage water) waste requiring special treatment. There are many type of  waste water technology processing, the most important, It can be applied  and product water quality meet the standard quality. Keywords : Sampah, 3 R, Tempat Pembuagan Akhir (TPA), Leachate Treatment

In big cities, the water quality of rivers used as the main raw water sources is getting worse and worse. That is caused by a lot of improper wastewater management systems, especially in industrial and settlement areas. As an example, the raw water of PDAM TKR Bojong Renged which is taken from Cisadane  Rives contains Ammonia 3.8 mg/l and it means that the content is not allowed to be used as the raw water for drinking water purpose. To cope with the problem, a bofiltration process can be used as one alternative to reduce Ammonia till the required standard quality.  A honeycomb tube type made plastic was the media of biofilter reactor. Operational condition was varied with HRT (Hydrolysis Retention Time) between 1-4 hours and air supply between 0-30 l/minute. The best process condition was found at 2 hour-HRT and 20 l/minute air supply and the Ammonia removal efficiency was about 65%. The linear regression equation was  ya  = -91.19xa + 77.12, where Y is for removal efficiency and the axis X is for Ammonia loading.  Keywords:  raw  water quality, ammonia, biofiltration, honeycomb tube, removal efficiency,

Environmental contamination and global climate change cause degradation of  fresh water in the whole world. Increasing of oil price also insist the water treatment operational cost rise, especially for pumping and water lifting from the low land areas to up land. One of alternatif solution to reduce operational cost is using Hydraulic ram pumps (hydram pump). Hydram pump are water-lifting devices that are powered by filling water. Such pumps work by using the energy of water falling a small height to lift a small part of that amount of water to a much greater height. In this way, water from a spring or stream in a valley can be pumped to a village or irrigation scheme on the hillside. The main and unique advantage of hydram pumps is that with a continuous flow of water, a hydram pump operates automatically and continuously with no other external energy source - be it electricity or hydrocarbon fuel. It uses a renewable energy source (stream of water) mid hence ensures low running cost. Minimum up lifting vertical power of pump is twice than vertical distance of water down and maximum up lifting vertical  power is twenty times than vertical distance of water down.   If there are air captured in distribution pipe, it will need release valve. In this paper, different aspect of designing a hydraulic-rain pump system is discussed. Application and limitation of hydram pump is presented. It imparts absolutely no harm to the environment Hydraulic ram pumps are simple, reliable and require minimal maintenance. All these advantages make hydram pumps suitable to rural community water supply and mud backyard irrigation in developing countries. Kata Kunci : Air bersih pedesaan, pompa hidram, pengelolaan air bersih.

Coastal Aquifer System of Jakarta consist of unconfined aquifer layers, confined aquifer I and  confined aquifer II.  Resources of  groundwater is very important for Jakarta City, for drinking water, industry, hotel, government offices and various other facility. Important considering of    groundwater resources of Jakarta hence needed an effort to preserve the groundwater and awake its continuity by conducting a system management of groundwater. Model used for the management of groundwater system of aquifer coastal referred as Groundwater Model Simulation and Optimization of Quasi Three Dimension ( OPT-Q3D). Model simulation and optimization represent computer model of quasi-three dimensions with method of finite difference used for the operation of infiltration of sea water. This model can conduct current simulation of groundwater flow, head of fresh water and brine, and describe the movement of interface fresh water and sea water. The model can also make optimization of system aquifer with single or multi layers.  Jakarta Groundwater Basin assumed consist three layers of aquifer separated by impermeable layer. Applying of groundwater simulation model in Jakarta can give information regarding balance of groundwater, head of freshwater, head of  brine, interface brine and freshwater, map of brine distribution and bargain in each; every aquifer. Herein after model optimization will yield various information able to wear upon which consideration to manage the amount of pumping of optimal ground water every area in each layer of aquifer, amount of optimal pumping, optimal freshwater head, head of optimal brine and map of infiltration.  Kata Kunci  : Air Tanah, Pengelolaan, Intrusi Air Laut, Modeling
