Macrozoobentos Diversity in Sipoholon Hot Spring in Sipoholon District, North Tapanuli Regency: A Study on Ecosystem Resistance

Introduction

The Sipoholon Hot Spring, located in the Sipoholon District of North Tapanuli Regency, is a unique ecosystem that supports a diverse range of macrozoobenthos species. Macrozoobenthos, which refers to the large invertebrate animals that live in aquatic environments, play a crucial role in maintaining the health and balance of aquatic ecosystems. This study aims to investigate the diversity of macrozoobenthos in the Sipoholon Hot Spring and to identify the factors that influence their distribution and abundance.

Methodology

The study was conducted in March 2013, and four sampling stations were selected using the Purposive Random Sampling method. Sampling was carried out using the GrabB Eckman tool and Surber net, and species identification was performed in the Laboratory of Natural Resources and Environmental Resources, the Department of Biology, Faculty of Mathematics and Natural Sciences, University of North Sumatra.

Results

The results of the study showed that the macrozoobenthos in the Sipoholon Hot Spring were classified into three classes: crustaceans, gastropods, and insecta. A total of seven genera were identified, including Chironomus, Ephidra, Pedicia, Limnea, Pleucera, Hydrobiomorpha, and Ghompus. Chironomus was found to be the dominant species, with a density value of 190 individuals/m², relative density of 100%, and attendance of 80%.

Discussion

The results of the study indicate that the Sipoholon Hot Spring has a relatively low diversity of macrozoobenthos. The dominance of Chironomus and the low diversity of other species suggest that the ecosystem is under stress. The positive correlation between water temperature and macrozoobenthos diversity also suggests that temperature is an important factor that affects the diversity of macrozoobenthos in the Sipoholon Hot Spring.

Macrozoobentos Diversity Patterns

The diversity analysis showed that the highest diversity index was found at station 4 (12,971), while the lowest index was in station 1 and station 3 (1). The highest uniformity index was found at station 2 (15.93) and the lowest at station 1 and station 3 (1). The pattern of macrozoobenthos diversity in each station shows a unique group or group, and does not follow a normal pattern.

Temperature as a Main Influence Factor

Correlation analysis showed that water temperature has a positive correlation to macrozoobenthos diversity. The higher the water temperature, the lower the diversity of macrozoobentos. This suggests that temperature is an important factor that affects the diversity of macrozoobenthos in the Sipoholon Hot Spring.

The Importance of Macrozoobentos in Aquatic Ecosystem

Macrozoobentos plays an important role in water ecosystems as a food source for other animals, decomposing organic matter, and water quality indicators. The existence of various macrozoobentos shows that the water ecosystem is in good health.

Conclusion and Recommendations

This study shows that the Sipoholon Hot Spring has a relatively low diversity of macrozoobenthos. Chironomus dominance and positive correlation between water temperature and macrozoobenthos diversity indicate that water temperature is a major factor that affects macrozoobenthos diversity. It is essential to monitor and conservation efforts to maintain the diversity of macrozoobenthos at the Sipoholon Hot Spring, so that the ecosystem is maintained and beneficial to the community.

Future Research Directions

Future research should focus on investigating the impact of water temperature on macrozoobenthos diversity and the role of other environmental factors, such as pH and dissolved oxygen levels, on the distribution and abundance of macrozoobenthos species. Additionally, studies on the conservation and management of macrozoobenthos in the Sipoholon Hot Spring should be conducted to ensure the long-term sustainability of the ecosystem.

Limitations of the Study

This study has several limitations. Firstly, the sampling method used may not be representative of the entire ecosystem. Secondly, the study only focused on the diversity of macrozoobenthos and did not investigate other aspects of the ecosystem, such as the diversity of fish and other aquatic species. Finally, the study was conducted in a single location, and future research should be conducted in other locations to compare the results and identify any patterns or trends.

Conclusion

In conclusion, this study provides valuable insights into the diversity of macrozoobenthos in the Sipoholon Hot Spring and the factors that influence their distribution and abundance. The results of the study suggest that the Sipoholon Hot Spring has a relatively low diversity of macrozoobenthos, and that water temperature is an important factor that affects their diversity. The study highlights the importance of monitoring and conservation efforts to maintain the diversity of macrozoobenthos in the Sipoholon Hot Spring and to ensure the long-term sustainability of the ecosystem.
