Analysis of Organophosphate Pesticide Residues (Dimetoat and Chlorpiration) in Rice Plants in Deli Serdang Regency

Introduction

The use of pesticides in agriculture, particularly in the cultivation of rice plants in Deli Serdang Regency, is a common practice to control pests and ensure a high yield. However, the use of pesticides can have a significant impact on the environment and human health. One type of pesticide that is widely used is organophosphate compounds, such as dimetoat and chlorpirifos, which have high efficiency in controlling pests. However, the presence of pesticide residues in food products can pose a risk to human health and the environment. Therefore, it is essential to analyze the level of pesticide residues in rice plants to ensure the safety of food consumption.

Background

Pesticides are widely used in agriculture to control pests and diseases that can damage crops. However, the use of pesticides can have a negative impact on the environment and human health. Organophosphate compounds, such as dimetoat and chlorpirifos, are commonly used pesticides that can persist in the environment and contaminate soil, water, and air. The presence of pesticide residues in food products can pose a risk to human health, particularly if consumed in large quantities or over an extended period.

Methodology

A study was conducted to measure the content of dimetoat residues and chlorpirifos in rice plants in several villages in Deli Serdang Regency. The analysis was carried out using the gas chromatography method with a fested photometric detector. The results show that from the sample taken, there is a difference in residual levels between different locations.

Results

From the results of the analysis, it was found that in rice plants from Penara Village, Tanjung Morawa District, there was no detected residue content in Dimetoat or Chlorpiration. Conversely, in rice plants from Durian Village, Pantai Labu District, there are levels of dimetoat of 0.736 mg/kg, while chlorpirifos are not detected. In other villages such as Beringin Village, Beringin District, chlorpirifos levels are detected at 0.232 mg/kg, while in the time it is not detected. Likewise, in the village of Aras Kabu, Deli Serdang District, identified 0.292 mg/kg chlorpirifos, while Dimetoat was not found again.

Discussion

All levels of pesticide residues detected far below the maximum residue limit (BMR) set for rice. In other words, the results of this analysis show that rice plants originating from local are still safe for consumption by the community. However, although the analysis results show residues below the threshold, it is essential to keep paying attention to the use of pesticides wisely and according to the rules so that the negative impacts for consumers and the environment can be minimized.

Conclusion

From the point of view of health and the environment, the existence of pesticides, although within a safe limit, should be watched out for. Excessive consumption or exposure to pesticides in the long run still has the potential to cause a negative impact on human health. In addition, pesticide residues that pollute soil and water can have an impact on local ecosystems and the health of other organisms. Therefore, there is a need for awareness and education to farmers regarding the use of responsible pesticides and more environmentally friendly agricultural techniques.

Recommendations

Thus, although the results of the analysis show that rice products from Deli Serdang Regency are safe for consumption, precise prevention and education steps must be prioritized. This kind of research is important to be carried out on an ongoing basis to ensure that the use of pesticides does not interfere with public health and environmental sustainability.

Future Research Directions

Future research should focus on the following areas:

Monitoring pesticide residues in rice plants: Regular monitoring of pesticide residues in rice plants is essential to ensure the safety of food consumption.
Development of environmentally friendly agricultural techniques: The development of environmentally friendly agricultural techniques can help reduce the use of pesticides and minimize their impact on the environment.
Education and awareness: Education and awareness programs for farmers regarding the use of responsible pesticides and more environmentally friendly agricultural techniques are essential to promote sustainable agriculture practices.

Limitations of the Study

The study has several limitations, including:

Limited sample size: The study only analyzed a limited number of rice samples from several villages in Deli Serdang Regency.
Limited analytical methods: The study only used gas chromatography with a fested photometric detector to analyze pesticide residues.
Limited data on pesticide use: The study did not collect data on pesticide use in the study area, which can limit the interpretation of the results.

Conclusion

In conclusion, the study found that pesticide residues in rice plants from Deli Serdang Regency are generally below the maximum residue limit (BMR) set for rice. However, the presence of pesticide residues in food products can pose a risk to human health and the environment. Therefore, it is essential to continue monitoring pesticide residues in rice plants and promote sustainable agriculture practices to minimize the negative impacts of pesticide use.
