Ammonia Analysis (NH3) Salisilate Method Using Hach Spectrophotometer Dr. 3900 in Wastewater in UPTD Laboratory of the Environment and Forestry Service (DLHK) of North Sumatra Province

Introduction

The quality of water in the UPTD Laboratory of the North Sumatra Province Environment and Forestry Service is a crucial aspect that needs to be monitored and maintained. The investigation was conducted to determine whether the water quality meets the provisions of the Waste Water Quality Standards as stipulated in the Regulation of the Minister of Environment of the Republic of Indonesia Number 68 of 2016. In this analysis, the parameter used is ammonia level (NH3). The method applied is the Salisilate method using the Hach Dr. 3900 Spectrophotometer device.

The importance of monitoring ammonia levels in wastewater cannot be overstated. Ammonia is a toxic substance that can have a serious impact on aquatic ecosystems. It can be toxic to aquatic organisms, affect the fish reproductive system, and damage the balance of aquatic ecosystems. Therefore, it is essential to examine the levels of ammonia in wastewater to ensure that the water quality meets the applicable standards.

Methodology

The analysis was conducted using the Salisilate method, which is a widely used method for determining ammonia levels in wastewater. The Hach Dr. 3900 Spectrophotometer device was used to measure the absorbance of the sample. The device is equipped with a spectrophotometer that can measure the absorbance of the sample at a specific wavelength.

The samples used in this analysis were obtained from the UPTD Laboratory of the North Sumatra Province Environment and Forestry Service. The samples were labeled with a unique code, and the ammonia levels were measured using the Salisilate method.

Results

The results of the analysis are presented in the following table:

Sample Code	NH3 Level (mg/L)
D/LC/01/24	0.99
E/LC/01/24	2.52
F/LC/01/24	2.66
H/LC/01/24	2.32

Based on the provisions in the Minister of Environment Regulation No. 68 of 2016, the maximum limit of ammonia levels for wastewater is 2 mg/l. From the data above, it appears that two samples, namely E/LC/01/24 and F/LC/01/24, exceed the specified threshold. This indicates that the water quality in both samples does not meet applicable standards and has the potential to have a negative impact on the environment if not handled properly.

Analysis and Implications of Results

The results of the analysis showing two samples exceeding the normal limit must be a major concern for related parties, such as the Department of Environment and Forestry. The high levels of ammonia in the wastewater can have a serious impact on aquatic ecosystems. Ammonia that is dissolved in water can be toxic to aquatic organisms, affect the fish reproductive system, and damage the balance of aquatic ecosystems.

Therefore, it is essential to take steps to deal with this condition. Improving the process of waste treatment, more efficient filtering, and the application of better technology to reduce NH3 levels before being discharged into the environment are some of the steps that can be taken. Periodic monitoring is also very important to ensure that wastewater quality standards are maintained and prevent further pollution.

Conclusion

The results of this analysis not only provide an overview of water quality in the UPTD Laboratory of DLHK North Sumatra Province, but also highlighted the importance of preventive measures and appropriate handling of the waste produced. Knowledge gained from this study can be used to formulate more effective policies in the management of wastewater in the future, as well as protect the aquatic ecosystem from sustainable pollution.

Recommendations

Based on the results of this analysis, the following recommendations are made:

Improve the process of waste treatment: The process of waste treatment should be improved to reduce the levels of ammonia in the wastewater.
More efficient filtering: More efficient filtering systems should be installed to reduce the levels of ammonia in the wastewater.
Application of better technology: Better technology should be applied to reduce NH3 levels before being discharged into the environment.
Periodic monitoring: Periodic monitoring should be conducted to ensure that wastewater quality standards are maintained and prevent further pollution.

By implementing these recommendations, the water quality in the UPTD Laboratory of DLHK North Sumatra Province can be improved, and the aquatic ecosystem can be protected from sustainable pollution.

Future Research Directions

Future research directions include:

Investigating the impact of ammonia on aquatic ecosystems: Further research is needed to investigate the impact of ammonia on aquatic ecosystems.
Developing more effective policies: More effective policies should be developed to manage wastewater and protect the aquatic ecosystem.
Improving waste treatment technology: Improving waste treatment technology is essential to reduce the levels of ammonia in the wastewater.

By conducting further research in these areas, the knowledge gained from this study can be used to formulate more effective policies in the management of wastewater in the future, as well as protect the aquatic ecosystem from sustainable pollution.
