Determination Of Mn (Manganese) Levels In Raw Water And Reservoir Water By Spectrophotometry In PDAM Tirtanadi Medan
Introduction
In an effort to ensure the quality of water supplied by PDAM Tirtanadi Medan, research was conducted to determine the level of manganese (Mn) in raw water and reservoir water. The study aimed to analyze the manganese content in water using a spectrophotometer of DR 5000 and indicator 1- (2-Piridil Azo) -2-Naftol (PAN). This method is able to form an orange color, indicating the presence of manganese content in water. The results of this study will provide valuable information on the level of manganese in the water provided by PDAM Tirtanadi Medan and ensure that it does not exceed the safe limit specified.
Methodology
The research was conducted using a spectrophotometer of DR 5000, which is a reliable and accurate instrument for determining the level of manganese in water. The indicator used was 1- (2-Piridil Azo) -2-Naftol (PAN), which is able to form an orange color when manganese is present in the water. The method used involves adding the indicator to the water sample and measuring the absorbance of the resulting solution using the spectrophotometer. The absorbance values were then used to calculate the level of manganese in the water.
Results
The results of the analysis show that the level of manganese in raw water ranges from 0.000 mg/l to 0.174 mg/l. Specifically, the values obtained from raw water samples are 0.045 mg/L, 0.056 mg/L, 0.000 mg/L, 0.174 mg/L, and 0.081 mg/L. Meanwhile, manganese content in reservoir water is lower, with a value of 0.008 mg/l, 0.017 mg/l, 0.005 mg/l, 0.017 mg/l, and 0.004 mg/l.
Analysis of Manganese Levels in Water
Based on the regulations on drinking water quality, safe levels of manganese for human consumption should not exceed 0.1 mg/l, while for the maximum fresh water is 0.5 mg/l. In this study, the level of manganese in both types of water tested turned out to be below the specified threshold. This shows that the water quality supplied by PDAM Tirtanadi Medan is still in the good category and is safe for consumption.
Manganese in low concentration is an element needed by the body, but in high quantities can cause various health problems. Therefore, it is important to carry out periodic monitoring of manganese levels in water to prevent pollution that can have an impact on public health.
Importance of Monitoring Water Quality
With the use of spectrophotometric technology, PDAM Tirtanadi Medan can increase efficiency in determining water quality. It also makes it possible to detect other contaminants more accurately. By maintaining water quality, PDAM Tirtanadi contributes to maintaining the health of the community and the environment.
Conclusion
Research conducted at PDAM Tirtanadi Medan shows that manganese content in raw water and reservoir water is within safe limits according to applicable standards. The importance of monitoring water quality routinely needs to be remembered to ensure the supply of clean water and is safe for the community. This effort will not only help in maintaining public health, but also increases public confidence in PDAM services.
Recommendations
Based on the results of this study, it is recommended that PDAM Tirtanadi Medan continues to monitor the level of manganese in raw water and reservoir water regularly. This will ensure that the water quality supplied by PDAM Tirtanadi Medan remains safe for consumption. Additionally, it is recommended that PDAM Tirtanadi Medan considers implementing measures to reduce the level of manganese in raw water and reservoir water, if necessary.
Limitations of the Study
This study has several limitations. Firstly, the study only analyzed the level of manganese in raw water and reservoir water, and did not consider other contaminants that may be present in the water. Secondly, the study only used a spectrophotometer of DR 5000, which may not be able to detect all types of manganese. Finally, the study only analyzed a limited number of water samples, which may not be representative of the overall water quality.
Future Research Directions
Future research should aim to analyze the level of manganese in raw water and reservoir water using more advanced methods, such as atomic absorption spectroscopy (AAS) or inductively coupled plasma mass spectrometry (ICP-MS). Additionally, future research should consider analyzing other contaminants that may be present in the water, such as heavy metals or pesticides. Finally, future research should aim to develop more effective measures to reduce the level of manganese in raw water and reservoir water.
Conclusion
In conclusion, this study shows that the level of manganese in raw water and reservoir water is within safe limits according to applicable standards. The importance of monitoring water quality routinely needs to be remembered to ensure the supply of clean water and is safe for the community. This effort will not only help in maintaining public health, but also increases public confidence in PDAM services.
