Macrozoobentos Diversity in the Downstream of Sungai Bah Tongguran: A Water Quality Indicator

Introduction

Sungai Bah Tongguran, a river flowing through Tanah Jawa District, Simalungun Regency, North Sumatra, is home to a diverse range of macrozoobentos, which play a crucial role as bioindicators in assessing the quality of the aquatic environment. Macrozoobenthos are aquatic animals that inhabit the riverbed and are sensitive to changes in water quality. In this study, we examined the diversity of macrozoobentos in the downstream of the Bah Tongguran River to determine its potential as a water quality indicator.

Background

Macrozoobenthos are an essential component of aquatic ecosystems, serving as a food source for various aquatic animals and playing a vital role in maintaining the balance of the ecosystem. However, their presence and diversity can be affected by changes in water quality, making them useful indicators of environmental health. In the context of Sungai Bah Tongguran, the diversity of macrozoobentos can provide valuable insights into the water quality of the river.

Methodology

The study was conducted between July and September 2016, using a purposive sampling method to select sampling points based on certain considerations. Macrozoobentos samples were collected using Surber Net nets and identified in the PSDAL Laboratory of the Biology Department, Faculty of Mathematics and Natural Sciences, University of North Sumatra, Medan. The diversity of macrozoobentos was calculated using the Diversity Index (H') method.

Results

The results of the study showed that the diversity of macrozoobenthos in the Bah Tongguran River was quite high, with three phylum, five classes, eight orders, 13 families, and 14 genus macrozoobentos identified. The highest macrozoobenthos diversity was found in station III with a value of 1.89, while the lowest diversity was in station I with a value of 1.46. These results suggest that the diversity of macrozoobentos in the Bah Tongguran River is influenced by the physical and chemical conditions of the water in each location.

Discussion

The differences in macrozoobentos diversity in each station can be associated with factors such as the level of dissolved oxygen, pH, temperature, and content of organic matter. These factors can affect the type and amount of macrozoobenthos that live in a waters. The macrozoobentos found in the Bah Tongguran River can be grouped into several categories based on their tolerance of pollution:

Intolerant Organisms: These organisms are very sensitive to pollution and can only live in waters with good quality. Their existence shows good water quality.
Tolerant Organisms: These organisms can live in waters with moderate pollution rates.
Organism Pollution Indicator: These organisms can only live in polluted waters.

Conclusion

The results of this study indicate that the Bah Tongguran River has a relatively good water quality. High macrozoobenthos diversity shows that rivers can still support the lives of various types of organisms. However, it is necessary to monitor and conservation efforts on an ongoing basis to maintain the quality of river water and sustainability of biodiversity in it.

Importance of Maintaining Water Quality

Maintaining the quality of the Bah Tongguran River water is crucial for several reasons:

Source of Clean Water: Sungai Bah Tongguran is a source of clean water for the surrounding community.
Habitat for Aquatic Biota: The river becomes a habitat for various types of fish, shrimp, and other aquatic animals.
Supporting Economic Activities: River Supports Fisheries and Tourism Activities.

By maintaining the quality of the Bah Tongguran River water, we can ensure environmental sustainability and the welfare of the surrounding community.

Recommendations

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

Regular Monitoring: Regular monitoring of water quality and macrozoobentos diversity should be conducted to ensure that the river remains healthy and sustainable.
Conservation Efforts: Conservation efforts should be implemented to protect the river and its surrounding ecosystem.
Community Engagement: Community engagement and education should be conducted to raise awareness about the importance of maintaining the quality of the Bah Tongguran River water.

By implementing these recommendations, we can ensure the long-term sustainability of the Bah Tongguran River and its ecosystem.
