Studies of Abundance of Sea Cucumbers in Seagrass Ecosystems on Unggh Island, Badiri District, Central Tapanuli Regency, North Sumatra Province

Introduction

Located in the Badiri District, Central Tapanuli Regency, North Sumatra Province, Unggh Island is renowned for its significant sea cucumber potential. Sea cucumbers, belonging to the echinodermata phylum, possess distinct characteristics, including soft thorny skin, cylindrical shapes, and slow movements. These marine creatures play a vital role in aquatic ecosystems, serving as deposit feeders, helping to decompose organic matter, and providing a source of food for marine predators.

In shallow waters, including seagrass ecosystems, sea cucumbers can be found thriving. This study aims to determine the abundance of sea cucumbers in the seagrass ecosystems of Unggh Island and analyze the conditions of the parameters in the ecosystem. The research method employed is a transect quadrant method, with a size of 5x5 meters, placed on a transect path along 100 meters, with a distance of 50 meters between the transect paths.

Methodology

The study was conducted at three observation points, each with unique coordinates:

• Station 1: 01º34'26,88 "LU and 098º45 '40.25" BT
• Station 2: 01º34'32.71 "LU and 098º45 '37.58" BT
• Station 3: 01º34'24.22 "LU and 098º45 '38.06" BT

The three types of sea cucumbers found in the seagrass ecosystems of Unggh Island are Actinopyga Aechinites, a. Miliaris, and Holothuria scabra. The observations reveal the density of sea cucumbers in each station: Station 1 has a density of 0.16 ind/m², station 2 with a density of 0.12 ind/m², and station 3 reaches a density of 0.4 ind/m². Overall, the density of sea cucumbers at the study site is 0.32 ind/m².

Results and Discussion

The abundance of sea cucumbers in the seagrass ecosystems of Unggreh Island indicates that this environment provides a fairly good condition for the growth and reproduction of sea cucumbers. Sea cucumbers play a crucial role in maintaining the balance of aquatic ecosystems through the filtering and decomposition process they perform. In addition, sea cucumbers are also one of the important components in the food chain, providing food for other sea predators.

The condition of a healthy seagrass ecosystem strongly supports the presence of sea cucumbers, considering seagrass functions as a habitat, shelter, as well as food sources for various marine life. Therefore, it is essential to maintain the health and sustainability of seagrass ecosystems, so that the population of sea cucumbers and other marine biota can be maintained.

Environmental Factors and Conservation Efforts

Environmental factors such as water quality, substrate, and the threat of pollution can also affect the abundance of sea cucumbers. Further research is needed to understand the dynamics of the sea cucumber population and how they interact with the surrounding ecosystem. Thus, efforts to conservation and management of sustainable biological resources can be carried out to maintain aquatic ecosystems, especially on Unggreh Island, as one of the regions with significant sea cucumber potential.

Conclusion

In conclusion, this study highlights the importance of sea cucumbers in seagrass ecosystems and the need to maintain a healthy and sustainable environment for their growth and reproduction. The findings of this study provide valuable insights into the abundance of sea cucumbers in the seagrass ecosystems of Unggh Island and emphasize the importance of conservation efforts to protect these marine creatures and their habitats.

Recommendations

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

• Further research is needed to understand the dynamics of the sea cucumber population and how they interact with the surrounding ecosystem.
• Conservation efforts should be implemented to protect the seagrass ecosystems and the sea cucumber population.
• Sustainable management practices should be adopted to maintain the health and sustainability of seagrass ecosystems.
• Education and awareness programs should be conducted to raise awareness about the importance of sea cucumbers and the need to protect their habitats.

Future Directions

Future studies should focus on the following areas:

• Investigating the impact of environmental factors on the abundance of sea cucumbers.
• Studying the dynamics of the sea cucumber population and their interaction with the surrounding ecosystem.
• Developing effective conservation and management strategies to protect the seagrass ecosystems and the sea cucumber population.
• Conducting education and awareness programs to raise awareness about the importance of sea cucumbers and the need to protect their habitats.

By addressing these research gaps and implementing effective conservation and management strategies, we can work towards maintaining the health and sustainability of seagrass ecosystems and protecting the sea cucumber population for future generations.
