Introduction

Mangrove forests play a vital role in maintaining coastal ecosystems, serving as a natural defense against coastal erosion and providing a habitat for a diverse range of marine life. However, the sustainability of these ecosystems is threatened by the accumulation of heavy metals, such as copper (Cu) and lead (Pb), which can have devastating effects on the health of mangrove trees and surrounding ecosystems. This study aims to investigate the accumulation of Cu and Pb on the Rhizophora mucronata tree in two different locations: the Fishing Village of Medan Labuhan District and the Fittle Jaring Village, Secanggang District.

Background

Mangrove forests are found in tropical and subtropical regions around the world, with Indonesia being home to some of the most extensive and diverse mangrove forests. The Rhizophora mucronata tree is a common species found in mangrove forests, known for its ability to thrive in saline and brackish environments. However, the accumulation of heavy metals in these ecosystems can have serious consequences, including the disruption of physiological processes, such as photosynthesis and growth, and the accumulation of toxins in the food chain.

Methodology

This study was conducted by taking samples from both locations and analyzing the content of heavy metals Cu and Pb in the laboratory of the Faculty of Pharmacy, University of North Sumatra, using the atomic absorption spectrophotometer method (AAS). The results show that the heavy metal content of Cu in bark and leaves in the village of nets is finely higher than the fishing villages. Conversely, the CU content in the roots is higher in fishing villages. Meanwhile, the heavy metal content of Pb on bark and roots in the village of the fine net is higher than the fishing villages. Conversely, the Pb content in the leaves is higher in fishing villages.

Results

The results of this study indicate that R. mucronata is able to accumulate heavy metals Cu and Pb, although its ability to accumulate Pb is lower than Cu. The difference in heavy metal content in both locations is likely caused by environmental factors such as the level of pollution, water flow, and human activity around the study site.

Discussion

The accumulation of heavy metals in high amounts can have a negative impact on the health of mangrove trees and surrounding ecosystems. Heavy metals can interfere with the physiological processes of plants, such as photosynthesis and growth, and can accumulate in the food chain, so that it can threaten human health. The results of this study highlight the importance of understanding the ability of R. mucronata in absorbing heavy metals and their effects on mangrove ecosystems.

Conclusion

This research is an important basis for understanding the ability R. mucronata in absorbing heavy metals and their effects on mangrove ecosystems. The results of this study can be used to:

Apply a sustainable mangrove forest management strategy, with a focus on prevention and reduction of heavy metal pollution.
Encourage further research on the ability of mangrove plants in absorbing heavy metals, to develop effective bioremediation technology.
Increase public awareness about the importance of preserving mangrove forests, as an effort to protect coastal ecosystems and human health.

Recommendation

Through joint efforts, we can maintain the sustainability of mangrove forests and minimize the risk of heavy metal pollution, so that future generations can enjoy the benefits.

Future Research Directions

Further research is needed to investigate the ability of R. mucronata in absorbing heavy metals and their effects on mangrove ecosystems. This can include:

Investigating the effects of heavy metal pollution on mangrove tree growth and productivity.
Developing effective bioremediation technology to remove heavy metals from mangrove ecosystems.
Increasing public awareness about the importance of preserving mangrove forests.

Conclusion

In conclusion, this study highlights the importance of understanding the ability of R. mucronata in absorbing heavy metals and their effects on mangrove ecosystems. The results of this study can be used to inform the development of sustainable mangrove forest management strategies and to encourage further research on the ability of mangrove plants in absorbing heavy metals.
