Mangan merupakan unsur yang secara alami dapat ditemukan di air, tanah, dan udara. Mangan adalah sebuah zat nutnsi esensial bagi manusia dan hewan. Asupan yang tidak mencukupi atau yang berlebihan dapat mcngakibatkan gangguan kesehatan Pajanan kronjk mangan pada dosis yang tinggi dapat mengakibatkan gangguan pada sistem sara Tujuan penelilian adalah mengetahui perkiraan resiko kesehatan akibat pemajanan mangau dari intake air yang dipcrolch dan sumur di wilayah pcnclitian. Penelitian ini dilakukan tcrhadap populasi di wilayah sekitar TPA Rawakucing, mencakup masyarakat yang bermukim di dalam kawasan TPA Rawakucing sebanyak 114 orang, dan di luar kawasan TPA yaitu 177 orang, Disain penelitian ini adalah crosseclionai dengan uji hipotesa. Hasil penelitian menunjukl-can rata-rata konsentrasi mangan dalam air sumur di wilayah sekitar TPA Rawakucing adalah 4.3 mg/I (SD=2.8873 mg/I). Scdangkan di luar TPA Rawakucing adalah 0,300 mg/l (SD=0.l888 mg/I). Konsentrasi mangan dalam air-air sumur yang ada di TPA tcrbukti secara bermakna berbeda dengan konsentrasi mangan pada air-air sumur di luar TPA (p<0.05). Rata-rata besaran risiko (RQ) gangguan kesehatan akibat mengkonsumsi air yang mengandung mangan pada masyarakat yang tinggai di TPA Rawakucing adalah 0.2347 dan rata-rata besaran risiko (RQ) gangguan keschatan masyarakat yang tinggat di luar TPA Rawakucing adalah 0.2955. Dan, ada pcrbedaan besar risiko gangguan kesehatan antara masyarakat yang tinggal di TPA dengan masyarakat yang tinggal di luar TPA (p<0_05) dcngan OR=8. |09 (95% CI = 2.668-24.650). Dari hasil penelitian ini terlihat ada kemungkinan kcberadaan TPA mempengaruhi kualitas air di Iingkungan sckitar TPA, khususnya Iogarn mangan yang mcmpengaruhi tingkat risiko. Unluk itu bagi Pcmcrintah Kota Tangerang perlu mempertimbangkan altematif sistem pengelolaan sampah di TPA Rawakucing, salah satunya dengan sistem pengeloiaan sanirary lamwll. Selain itu, perlu mempenimbangkan sistem pengelolaan air komunal yang dapal menghasilkan air yang memenuhi syarat untuk dikonsumsi. Bagi Dinas Kesehatan Kota Tangerang khususnya diharapkan mampu melakukan manajemen risiko tcrhadap masyarakat yang terbukti memiliki lisiko yang tinggi akan terkena toksisitas mangan di kemudian hari.
Manganese is a naturally-occurring element that can be found ubiquitously in the air, soil, and water. Manganese is an essential nutrient for humans and animals. Adverse health effects can be caused by inadequate intake or over exposure. Although manganese is an essential nutrient at low doses, chronic exposure to high doses may be harmful. Regardless, the nervous system has been determined to be the primary target organ with neurological effects generally observed. The objective ofthe study is to assess the health risk of manganese exposure from the well drinking water intake. This study was done in Final Disposal Site Rawalcucing area and out of this area . The number of subjects sampled were II4 and 117, respectively. Study design is cross-sectional with hypotesis test. The result showed that the average manganese concentration was 4.3 mg/l (SD#2.8873), 0.300 mg/l (SD=0.I888) respectively. The result was significant different statistically (p<0.05) tbr manganese concentration from two study area. The average RQ showed 0.2347 (SD=0_5095) for RQ in Disposal Site Area and 0.2955 (SD=0.2465) for RQ in out of Disposal Site Area. The result was significant different statistically (p<0.05) for RQ value, with OR=8. |09 (95% Cl = 2.668-24.650). It is recommended that The Government of Tangerang City should changed open dumping system in Disposal Site Rawakucing Area to sanirmy Ianajflll. Department of Health of Tangerang City especially, should be able to apply risk management to the community in the Disposal Site Rawakucing Area.
The existence of landfill can be a source of manganese (Mn) pollutants in the environment. Mn can cause toxic for kidney if excessive intake. The purpose of this study was to determine the relationship between Mn concentrations in ground water with kidney function disorders in the people living around the Cipayung Landfill. The research was a cross sectional study with 104 respondents which included Cipayung and Pasir Putih village. Kidney function disorders was determined by the level of proteinuria or hematuria determined by the semi-quantitative dipstick method. While the Mn measurements used SNI 6989.5: 2009. The results showed that Mn levels of ground water at 9 (13,6%) sampling points exceeded drinking water quality standards and 17 people (16.3%) showed changes in kidney function. Mn concentration were between 0.06 mg / L-0.84 mg /L. There was no relationship between Mn concentration in ground water with kidney function disorders. While risk factors for hypertension and obesity had a significant relationship with kidney function disorders (OR 4.20; 95%; CI: 1.27-13.84;
OR 3.64; 95%; CI: 1.10-12.07). The conclusions of this study is risk factors for hypertension and obesity have a significant relationship with kidney function disorders.

Water is an essential requirement that must be met for human survival. However,water services, especially in the area of Bekasi Well Batu Village, DistrictBantargebang mostly using wells for drinking water and other daily needs.Manganese and iron are essential nutrients needed by the body. However, whenconsumed in excessive amounts can be toxic. This research uses environmentalhealth risk analysis methods to estimate exposure levels of manganese and ironand acceptable health risks of drinking water in the adult population in thesettlements around landfills Bantargebang, Bekasi. In addition, this study alsotested the correlation between the manganese, iron, TDS, DHL, and so the pHfound a linear equation to predict the existence of manganese or iron. The studypopulation was the entire adult population living around the landfillBantargebang. The samples to determine inclusion criteria ie the population agedover 18 years and consume well water at least 2 months. Sampling by way of nonrandom sampling and quota sampling. Environmental samples is well water that isin the selected households as respondents. In addition, anthropometric datacollection is done in the form of intake rate, duration of exposure, and weight.Total intake of manganese and iron in the study population not meet nutritionaladequacy rate each ie 0.26 and 0.02 mg / l. From the calculation of risk estimatesshowed that the level of risk of manganese and iron around the landfillBantargebang not risky or safe. In addition, the correlation obtained from asignificant relationship between manganese with pH, DHL, and TDS (p <0.05)thus found a simple linear equation for each variable.
