| dc.description.abstract | Analysis of Iron (Fe) and Manganese (Mn) Levels in Drinking Water at UPT. Laboratorium Kesehatan Provinsi Sumatera Utara with Atomic Absorption Spectrophotometry. Examination of the levels of analysis of iron (Fe) and manganese (Mn) levels in drinking water using an Atomic Absorption Spectrophotometer (AAS) with the addition of 0.5 mL of nitric acid (HNO3). From the results of the analysis of iron (Fe) levels, iron levels were obtained (Fe) in sample code 0275 is 0.012 mg/L, sample code 0276 is 0.016 mg/L, sample code 0286 is 0.007 mg/L, sample code 0287 is 0.002 mg/L, sample code 0288 is 0.000 mg/L, sample code 0290 is 0.017 mg/L, and in sample code 0291 it is 0.386 mg/L. From the results of the analysis of manganese (Mn) levels in drinking water that has been carried out at UPT. The North Sumatra Province Health Laboratory obtained levels of manganese (Mn)) in sample code 0275 of 0.003 mg/L, sample code of 0276 of 0.000 mg/L, sample code of 0286 of 0.009 mg/L, sample code of 0287 of 0.002 mg/L, code sample 0288 was 0.001 mg/L, sample code 0290 was 0.003 mg/L, and sample code 0291 was 0.191 mg/L. Based on the data obtained from the analysis of iron (Fe) and manganese (Mn) levels in drinking water, it meets the water quality standards set by the Minister of Health of the Republic of Indonesia No.492/MENKES/PER/IV/2010. | en_US |
