Beach Profile Modeling For Estimated Beach Border Estimates In The Cermin Beach Area

by ADMIN 85 views

Introduction

Pantai Mutiara, a popular tourist destination located in Serdang Bedagai Regency, North Sumatra, is a charming beach that directly faces the Malacca Strait. However, this beach is not just a place of recreation; it is also a meeting point between the sea and land that experiences constant changes in its form, size, and material. These changes are generally caused by natural factors and, in recent years, the phenomenon of sea level increases that cause erosion. In this final project, the authors examine the potential increase in sea level and its impact on the setbacks of the coastline and the width of the coastal border.

Understanding Coastal Profile Modeling

Coastal profile modeling is a crucial tool in analyzing the setback of the coastline. The method applied in this study is the Bruun schematic, which serves to predict coastal erosion based on sea level rise. This method is essential in understanding how coastal profile modeling can be used to analyze the setback of the coastline and its impact on the width of the coastal border.

The Impact of Sea Level Rise on Pantai Mutiara

Based on the data obtained, the maximum erosion on Mutiara beach has reached 6,058 meters when the coastline has set a setback of 0.288 meters. Meanwhile, at a 1,684 meter coastline, there was a maximum erosion of 7,454 meters. This finding shows that Pantai Mutiara has a very high level of vulnerability to erosion caused by an increase in sea level. The data also suggests that the beach is expected to experience a setback of around 8.74 meters if the increase in sea levels occurs at a rate of 0.0015 meters per year. However, in the worst scenario with an increase in sea level of 0.0086 meters per year, this beach can experience setbacks of up to 50.14 meters.

The Importance of Coastal Protection Structures

Seeing the impact of rising sea levels and coastal erosion, it is essential for the government and the community to pay attention to the right mitigation steps. One step that can be taken is the construction of coastal protection structures, such as seawalls or planting coastal vegetation, which can help reduce the impact of erosion. In addition, education to the community about the importance of maintaining the coastal ecosystem is also very necessary so that the continuity of Mutiara Beach as a tourist attraction is maintained.

Conclusion

With this research, it is expected to provide deeper insight into the importance of coastal profile modeling in predicting the impact of climate change and sea level rise. Awareness of this issue can help the community and the government in planning the actions needed to protect Mutiara Beach and the surrounding environment, as well as improving the quality of life of the people who depend on coastal resources.

Recommendations

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

  • The government and the community should pay attention to the right mitigation steps to reduce the impact of coastal erosion.
  • Coastal protection structures, such as seawalls or planting coastal vegetation, should be constructed to help reduce the impact of erosion.
  • Education to the community about the importance of maintaining the coastal ecosystem is also very necessary.
  • Further research should be conducted to provide more accurate predictions of the impact of sea level rise on coastal areas.

Limitations of the Study

This study has several limitations, including:

  • The data used in this study is limited to the period of 2010-2020.
  • The study only focuses on the impact of sea level rise on Pantai Mutiara and does not consider other factors that may contribute to coastal erosion.
  • The study assumes that the increase in sea level will occur at a constant rate, which may not be the case in reality.

Future Research Directions

Based on the findings of this study, the following future research directions are suggested:

  • Conducting further research to provide more accurate predictions of the impact of sea level rise on coastal areas.
  • Investigating the impact of other factors that may contribute to coastal erosion, such as human activities and climate change.
  • Developing more effective coastal protection structures to help reduce the impact of erosion.
