Microplastic Abundance in Lake Siuro, Medan Marelan: A Threat to Aquatic Ecosystems

Introduction

Microplastic has become a significant pollutant in aquatic ecosystems worldwide, posing a threat to the health of our planet. These tiny plastic particles are not only hazardous but also have hydrophobic properties and contain harmful chemicals, including persistent organic pollutants (POP). The presence of microplastic in waters can cause severe chemical pollution, affecting life in the water. One of the locations of concern is Lake Siuro, located in the coastal area of Medan, which is estimated to be a microplastic distribution channel to surrounding waters. This study aims to analyze the distribution of microplastics in water, sediments, and fish in Lake Siuro and provide recommendations for lake management to reduce microplastic impacts.

Background

Microplastic pollution has become a pressing issue globally, with its effects on aquatic ecosystems and human health being well-documented. The use of microbeads in personal care products, microfibers from clothing, and plastic debris from various sources have contributed to the accumulation of microplastics in our oceans and waterways. The consequences of microplastic pollution are far-reaching, from harming marine life to contaminating the food chain and ultimately affecting human health. In the context of Lake Siuro, the presence of microplastic pollution poses a significant threat to the lake's ecosystem and the surrounding communities that rely on it for their livelihood.

Methodology

A study was conducted between November 2021 and January 2022 to analyze the distribution of microplastics in water, sediments, and fish in Lake Siuro. Water samples were collected using a 90 g NaCl solution, and the microplastic testing process was carried out by visual separation using a microscope. For microplastic in sediment, the separation process involved several stages, including drying, volume reduction, separation based on density, filtration, and visual observation. Meanwhile, for fish, their digestive organs were taken and dissolved with 10 ml of saturated NaCl. The results showed that microplastic pollution in water ranged from 42 to 263 particles/m³, whereas in sediments 521 to 1481 particles/kg of dry sediment were found. In the digestive organs of the fish, the number of microplastics detected ranged from 0 to 6 individual particles.

Results

The results of the study indicate that microplastic pollution is a significant issue in Lake Siuro, with high concentrations of microplastics found in water, sediments, and fish. The presence of microplastics in the lake's ecosystem poses a threat to the health of aquatic life and the surrounding communities that rely on the lake for their livelihood. The high concentrations of microplastics in sediments and fish digestive organs suggest that microplastic pollution is not only limited to the water column but also affects the lake's sediment and biota.

SWOT Analysis

A SWOT analysis was conducted to identify the strengths, weaknesses, opportunities, and threats associated with microplastic pollution in Lake Siuro. The analysis revealed that the lake's ecosystem is vulnerable to microplastic pollution, with high concentrations of microplastics found in water, sediments, and fish. The study recommends using the WT (Weakness-Threat) strategy, which focuses on efforts to minimize weaknesses and handle existing threats. Proactive management steps are needed to reduce the impact of microplastic pollution, including increasing public awareness about the importance of maintaining the cleanliness of the lake and enforcing laws against pollution.

Conclusion

Facing microplastic problems in Lake Siuro requires collaboration between the government, the community, and scientists to ensure that the lake ecosystem remains healthy. Awareness of microplastic threats is not only limited to one location but must also be a concern throughout the world. Efforts to improve sustainable environments must be a priority, so that we can protect vital water resources for life. By educating the community and taking concrete actions in environmental management, we can not only reduce the impact of microplastic but also improve the quality of aquatic ecosystems as a whole. This is essential so that future generations can inherit a better and cleaner environment.

Recommendations

Based on the study's findings, the following recommendations are made:

Increase public awareness: Educate the community about the importance of maintaining the cleanliness of Lake Siuro and the impact of microplastic pollution on the lake's ecosystem.
Enforce laws against pollution: Strengthen laws and regulations against pollution, including microplastic pollution, to prevent further degradation of the lake's ecosystem.
Implement sustainable practices: Promote sustainable practices, such as reducing plastic use, increasing recycling, and implementing effective waste management systems, to reduce microplastic pollution.
Conduct regular monitoring: Conduct regular monitoring of microplastic pollution in Lake Siuro to track the effectiveness of management efforts and identify areas for improvement.
Collaborate with stakeholders: Collaborate with stakeholders, including government agencies, community groups, and scientists, to develop and implement effective management strategies for Lake Siuro.

By implementing these recommendations, we can reduce the impact of microplastic pollution in Lake Siuro and protect the lake's ecosystem for future generations.
