Analytical chemistry is one branch of chemistry in which there is a way to determine certain ion levels using selective and specific reagents. One type of ion that can be known is the sulfate ion. Sulfate ions are one of the main anions that appear in water naturally. Sulfate is one of the important ions in water availability because of its important effect on humans when it is available in large quantities. The maximum limit of sulfate in water is around 250 mg / L for human-consumed water. This study uses qualitative analysis to determine whether water in the Jakabaring Sport City Palembang region contains sulfate ions or not. Samples taken directly from five different points were reacted with HCl and BaCl2. The results obtained are the five positive water samples containing sulfate ions which are characterized by the formation of white deposits.

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.
地下水是人们容易获得清洁水的主要替代方案之一，因为施工相对容易。因此，垃圾填埋场周围的居民使用地下水。最终处置场(TPA)是废物管理达到最后阶段的地方。垃圾填埋场周围的井水通常会被各种对人体有害的化学物质污染，其中一种是有机物。有机物是指含有大量碳的物质。例如苯、氯仿、洗涤剂和五氯苯酚。高浓度的有机物表明水已经被污染了。因此，测定井水样品中有机物的含量可以使水质得到已知的质量。为确定社区井水样品中有机物含量，采用高锰钾滴定法进行了定量分析。高锰酸钾滴定法的原理是，在酸性气氛中，有机物可以被KMnO4加热氧化。剩余的KMnO4被过量的草酸还原。过量的草酸用KMnO4再次滴定。分析结果表明，社区钻探井水样品中有机质含量为586.8 mg / l，不符合饮用水标准，不适合饮用。根据印度尼西亚共和国卫生部长第492 / MENKES / SK / VI / 2010号文件，饮用水的有机物质含量不超过10毫克/升。这是因为有机物的数量会导致微生物数量的增加，并可能导致人体中危险致病菌的发展，特别是对免疫系统。

As for the methods used for the determination of the levels of ammonia (NH3) in the liquid waste K-36, i.e. using Nessler method before it is analyzed using spectrophotometer UV-Vis instruments. the test results obtained on the acidity and the ammonia levels different – different, the level of acidity that can range in 8.2 to 9.3. Whereas the levels of ammonia in can range up to 130 ppm 240 ppm. the levels of ammonia in the water channel K-36 still belongs to secure because it is still in the range 200 ppm and will still be in the aeration to evaporate ammonia before water dumped into the river.","PeriodicalId":196624,"journal":{"name":"ALKIMIA : Jurnal Ilmu Kimia dan Terapan","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134147035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research has been carried out on the analysis of the content of Fe (II) in sewage water around TPA II in the sub-district of the glorious work of Palembang 2 with a UV-Vis spectrophotometry method. This study was conducted to determine the iron content of leachate water around the final disposal site using the UV-Vis spectrophotometry method. The results of the characterization of leachate with UV-Vis spectrophotometry showed the highest iron metal content at point 4 to 4 at 2.767 mg / I with an average content of 0.7308 mg/I which exceeded the quality standard of water quality in accordance with Government Regulation No.82 of 2001 that the iron content allowed in class I water quality quality standards is 0.3 mg / I.
