The community around Tempat Pembuangan Akhir (TPA) II Musi II Kelurahan Karya Jaya still relying on borehole water to fulfill their daily needs. The existence of TPA around these community environments can have a negative impact, including an indication of contamination of borehole water. One of the water pollution that is suspected to occur due to contamination of leachate from TPA is over chloride level in borehole water. The present work aimed at determining chloride level in borehole water in the area around Musi II TPA II Musi II Kelurahan Karya Jaya using Mohr argentometry titration method. The results showed chloride level in borehole water in the area around Musi II TPA II Musi II Kelurahan Karya Jaya is 301.75 mg/L. Based on PerMenKes RI No.492/MENKES/SK/VI/2010 and PerMenKes RI No.416/MENKES/ PER/IX/1990, the maximum level of chloride for drinking water is 250 mg/L, while for clean water is 600 mg/L, so that it can be concluded that borehole water in the area around Musi II TPA II Musi II Kelurahan Karya Jaya can’t be used for primary needs, for example drinking and cooking needs, but borehole water can still be used for secondary needs such as bathing and washing.

Groundwater is one of the main alternatives for people to get clean water easily, because the construction is relatively easy. Therefore residents around the landfill use ground water. Final Disposal Site (TPA) is a place where waste has reached the final stage in its management. Well water around the landfill will usually be polluted by various chemicals that are harmful to the body, one of which is organic matter. Organic substances are substances that contain a lot of carbon. Examples are benzene, chloroform, detergent, and pentachlorophenol. High levels of organic matter indicate that the water has been polluted. Therefore, the determination of the level of organic matter in the samples of borehole water so that the quality can be known quality. To determine the level of organic matter in the sample of community drill well water, quantitative analysis was carried out using the permanganometric titration method. The principle of the permanganometric titration method is that organic matter can be oxidized with KMnO4 in an acidic atmosphere by heating. The remaining KMnO4 is reduced with excess oxalic acid. The excess oxalic acid is titrated again with KMnO4. Based on the results of the analysis, the levels of organic matter contained in well water samples amounted to 586.8 mg / L. So it can be concluded that the sample of community drill well water is not suitable for drinking, because it does not meet the criteria of drinking water. The criteria for drinking water according to the Minister of Health of the Republic of Indonesia No.492 / MENKES / SK / VI / 2010 are not containing more than 10 mg / L of organic matter. This is because the amount of organic matter will result in increasing the population of microorganisms and can lead to the development of dangerous pathogenic bacteria in the human body, especially for the immune system.

ABSTRACT Well water is a source of water that is used by the community around the landfill for everyday life. The well water is not far from the landfill site. Based on observations the environment around the TPA is very dirty and there are puddles of water, so it is not good for residents who are around TPA to use well water for their daily lives. Some simple methods can be done to determine the condition of well water, one of which is by simple physical and chemical testing. Simple physics tests are carried out by looking at changes in color, turbidity, and odor while chemical tests are carried out by mixing sample solutions with tea. In the physical and chemical test of the well water of the residents around the TPA 2 in Palembang, it can be concluded that the well water around the TPA has a cloudy color, a strong odor and a pH of 7.
