Karawang area is well known as an agriculture area and 2% area is utilized for industries. Clean water demands increase due to developing industry development and population increasement. The origin of groundwater is necessary to keep the sustainability of water resources in this area. Stable isotopes such as 18O and 2H can be used as a parameter to trace the ground water origin. The methods used were Epstein-Mayeda and Zinc reduction for analysis 18O and 2H, respectively. Sampling period was conducted in major dry season in year 2002. The result showed that evaporation effect had influenced to the content of both isotopes in its shallow groundwater that caused a slope shift from its local meteoric line. The origin of its shallow groundwater was from rainwater infiltrating directly in less than 10 m altitude. Citarum River showed more depleted values in both isotopes compared to shallow groundwater and it indicated that its water might originate from spring at the altitude of 600 m.     Keywords: oxygene-18, deuterium, groundwater, isotope

Water demand is increasing, but thus water resources are increasingly threatened due to the increasing use and pollution of the environment, therefore there is a need for long-term strategies regarding water use in order to maintain the sustainability of water resources in Indonesia, especially in the DKI region This study shows the effective steps in the efficient use of the water in the Astra South Jakarta property area, by reengineering the water recycling system, which uses the Overall Equipment Effectiveness (OEE) method. The results of this design have been able to increase engine effectiveness from 51.9% to 88.9% and water recycling productivity up 168% (production from 20m 20 to 54m³ per day), so that can reduce PDAM water supply 16.6% (water requirement before the system re design are an average of 4,088.2 m³ per month, after redesigning the system 3,407 m³ per month). The redesign of the system is also able to prepare water reserves that can supply water for the development of Astra properties in the area of around 20m per day. At DKI Profession level, the design of the reengineering can contribute to the DKI Jaya, the water supply of 0.00002% per day and can reduce the utilization of ground water because the water needs in Astra have been fulfilled.

Population Movement

Stable isotopes present in local ground water get into people's teeth before they are 12 years old, and act as a signature to the area where they grew up (and drank the water). In a review of recent work in Britain the authors show the huge potential of this method for detecting population movement – and thus ultimately for investigating questions of migration, exogamy and slavery.

Daily Water

Clean water to poor communities who live in crowded municipal area is stillexpensive and a luxury. This condition is evidenced by the number of people whouse ground water for their daily water, because water taps still seems expensivefor them. Diarrheal disease is still relatively high for Indonesia, where nearly 16thousand people suffer from diarrhea due to poor sanitation. To help the poor inthe city, there are several alternative technologies that can be applied to publicaccess to clean water and adequate low-cost, including ground water treatmenttechnology with a filter system equipped with an ultraviolet sterilizer, or ozonegenerators, or using ultrafiltration, if possible can also use the reverse osmosismembrane that for fresh water. Arsinum is the best alternative should be chosenfor fulfilled potable water in slump area.Keywords : Sanitation, water treatment technology, portable water, low-cost, slump area
