Plankton Diversity in Sei Nipah Waters, Sei Nagalawan Village, Perbaungan District: A Study on the Abundance and Relationship with Physical and Chemical Parameters

Introduction

Located in Perbaungan District, Serdang Bedagai Regency, Sei Nipah waters are a vital component of the surrounding community, serving as a residence for residents of Sei Nagalawan Village, a hub for fisheries activities, and a popular tourist destination. However, the increasing human activities in the area have the potential to impact the diversity of plankton and water quality. This study aims to explore the abundance of plankton, diversity of types, and the relationship between physical and chemical parameters and plankton diversity in Sei Nipah waters.

Background

Sei Nipah waters are a complex ecosystem that supports a diverse range of aquatic life, including phytoplankton and zooplankton. Phytoplankton are microscopic plant-like organisms that form the base of the aquatic food web, while zooplankton are small animal-like organisms that feed on phytoplankton. The diversity of plankton in Sei Nipah waters is influenced by various physical and chemical factors, including temperature, salinity, pH, dissolved oxygen (DO), and nutrient levels.

Methodology

This study was conducted between September and October 2020, with three observations made every two weeks. At each observation station, plankton samples were taken three times at different times, namely at 08.00, 12.00, and 16.00 WIB. Measurement of water quality was carried out at three station points with an in-situ method for parameters such as temperature, salinity, pH, DO, and brightness, as well as the ex-situ method to measure total nitrogen and phosphate.

Results

The results of this study showed that the diversity of phytoplankton in each station was in the medium category, while the diversity of zooplankton was low. The relationship between temperature, brightness, DO, pH, and salinity to phytoplankton diversity shows a very strong and unidirectional relationship. Conversely, the relationship between the speed of current and total nitrogen to the diversity of phytoplankton is detected weak and not in the same direction. For phosphate, there is a strong relationship but not in the same direction with phytoplankton diversity.

On the other hand, for zooplankton, the relationship of temperature and brightness shows a weak but unidirectional relationship, while the relationship of current and phosphate to the diversity of zooplankton is strong and unidirectional. DO quality also shows a relationship that is in line with the diversity of zooplankton, while pH and salinity show a connection that is not in the same direction. Total nitrogen affects the diversity of zooplankton with relatively strong relationships but also not in the same direction.

Discussion

The results of this study suggest that the diversity of plankton in Sei Nipah waters is influenced by a number of physical and chemical factors. The strong and unidirectional relationship between temperature, brightness, DO, pH, and salinity to phytoplankton diversity indicates that these factors play a crucial role in shaping the phytoplankton community in the area. Conversely, the weak and not in the same direction relationship between the speed of current and total nitrogen to the diversity of phytoplankton suggests that these factors have a limited impact on phytoplankton diversity.

For zooplankton, the weak but unidirectional relationship between temperature and brightness suggests that these factors have a limited impact on zooplankton diversity. However, the strong and unidirectional relationship between current and phosphate to the diversity of zooplankton indicates that these factors play a crucial role in shaping the zooplankton community in the area.

Conclusion

In conclusion, this study highlights the importance of understanding the relationship between physical and chemical parameters and plankton diversity in Sei Nipah waters. The results of this study suggest that the diversity of plankton in the area is influenced by a number of physical and chemical factors, including temperature, salinity, pH, DO, and nutrient levels. The findings of this study have important implications for the management of Sei Nipah waters and the preservation of aquatic ecosystems.

Recommendations

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

Monitoring of water quality: Regular monitoring of water quality is essential to understand the impact of human activities on the diversity of plankton in Sei Nipah waters.
Conservation of aquatic ecosystems: Efforts should be made to conserve and protect the aquatic ecosystems in Sei Nipah waters, including the preservation of phytoplankton and zooplankton communities.
Sustainable management of natural resources: The sustainable management of natural resources in Sei Nipah waters is essential to maintain the balance of ecosystems and water quality.
Community awareness: The community should be aware of the importance of preserving the aquatic environment as part of the sustainability of their lives.

Future Research Directions

This study provides a foundation for future research on the diversity of plankton in Sei Nipah waters. Future studies should focus on:

Long-term monitoring: Long-term monitoring of water quality and plankton diversity is essential to understand the impact of human activities on the aquatic ecosystems in Sei Nipah waters.
Impact of climate change: The impact of climate change on the diversity of plankton in Sei Nipah waters should be investigated.
Effect of human activities: The effect of human activities, including fisheries and tourism, on the diversity of plankton in Sei Nipah waters should be investigated.

By understanding the relationship between physical and chemical parameters and plankton diversity in Sei Nipah waters, this study provides valuable information for related parties in making decisions and management of water resources in this region. The community is also expected to be more aware of the importance of preserving the aquatic environment as part of the sustainability of their lives.
Frequently Asked Questions (FAQs) about Plankton Diversity in Sei Nipah Waters

Q: What is plankton diversity, and why is it important?

A: Plankton diversity refers to the variety of plankton species present in a given body of water. Plankton are small, usually microscopic, organisms that drift in the water column, and they play a crucial role in the aquatic food web. Understanding plankton diversity is essential for maintaining the health and balance of aquatic ecosystems.

Q: What are the main factors that influence plankton diversity in Sei Nipah waters?

A: The main factors that influence plankton diversity in Sei Nipah waters include temperature, salinity, pH, dissolved oxygen (DO), and nutrient levels. These factors can impact the growth, survival, and distribution of plankton species.
