Introduction

Understanding the Importance of Polymesoda Erosa in Ecosystems and Economics

Polymesoda erosa, also known as the kepah, is an invertebrate animal that plays a vital role in maintaining the balance of ecosystems and contributing to the economy. Unfortunately, human activities and exploitation by the community and fishermen have threatened the population of kepah in their natural habitats. This study aims to investigate the population density, growth patterns, and distribution patterns of Polymesoda Erosa at Kuala Putri Beach, Pantai Cermin District, Serdang Regency, North Sumatra.

Methodology

Sampling Method and Study Area

This study employed the "purposive sampling" method, taking into account human activity around the study area. Three stations were selected: Station 1 (Activity Free Area), Station 2 (Tourism Area), and Station 3 (Sampan Stop area). Sampling was done randomly using a can of cans. At each station, two plots of 7x5 meters were made with a distance of 15 meters between the plots.

Data Collection and Analysis

The results of the study showed that the highest population density was found at Station 2 (7500 individuals/ha), while the lowest was at Station 1 (5500 individuals/ha). The pattern of growth in each station showed negative allometrics (B <3), indicating that the length increase was more dominant than the weight increase. This suggests that the kepah at that location experienced a faster long growth compared to its weight growth.

Distribution Pattern of Polymesoda Erosa

The pattern of distribution of kepah at each station had an ID <1 value, indicating that the kepah were scattered in groups. This grouping may be caused by factors such as the availability of food, water flow, or the presence of predators.

Discussion

Population Density and Human Activity

The results of this study provide an overview of the condition of the population of kepah at Kuala Putri Beach. A higher population density at Station 2, which is a tourism area, suggests that human activity can have a positive impact on the density of the kepah population. However, it is essential to note that this research was conducted in one location and for one period of time. To obtain more comprehensive results, further research needs to be done with a broader scope and a longer observation period.

Conservation Efforts

Given the important role of Polymesoda Erosa in ecosystems and the economy, conservation efforts need to be made to protect the population of kepah in Kuala Putri Beach. This includes implementing measures to reduce human impact on the environment, protecting the habitat of kepah, and promoting sustainable fishing practices.

Conclusion

This study provides valuable insights into the population density, growth patterns, and distribution patterns of Polymesoda Erosa at Kuala Putri Beach. The results highlight the importance of conservation efforts to protect the population of kepah and maintain the balance of ecosystems. Further research is needed to obtain more comprehensive results and to develop effective conservation strategies.

Recommendations

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

Conduct further research with a broader scope and a longer observation period to obtain more comprehensive results.
Implement conservation efforts to protect the population of kepah in Kuala Putri Beach.
Promote sustainable fishing practices and reduce human impact on the environment.
Protect the habitat of kepah and maintain the balance of ecosystems.

Limitations of the Study

This study has several limitations, including:

The study was conducted in one location and for one period of time.
The sample size was limited, and further research is needed to confirm the findings.
The study did not consider other factors that may affect the population density and growth patterns of Polymesoda Erosa.

Future Research Directions

Future research should focus on:

Conducting further studies with a broader scope and a longer observation period.
Investigating the impact of human activity on the population density and growth patterns of Polymesoda Erosa.
Developing effective conservation strategies to protect the population of kepah in Kuala Putri Beach.

Conclusion

In conclusion, this study provides valuable insights into the population density, growth patterns, and distribution patterns of Polymesoda Erosa at Kuala Putri Beach. The results highlight the importance of conservation efforts to protect the population of kepah and maintain the balance of ecosystems. Further research is needed to obtain more comprehensive results and to develop effective conservation strategies.
