Understanding the Importance of Coastal Monitoring

Changes in coastline due to erosion and accretion are complex problems that have the potential to cause various environmental and social consequences. Coastal zone management is very important to maintain the stability and sustainability of the beach. In this context, coastline monitoring uses the latest technology, such as drones, is an effective alternative. This study was focused on Mutiara Beach in Serdang Bedagai Regency, which aims to identify changes in coastlines between 2018 and 2020.

Coastal monitoring is a crucial aspect of protecting coastal ecosystems and ensuring the sustainability of the coastal zone. The threat to the coastline will increase due to the increasingly apparent climate change. Therefore, it is essential to have effective monitoring systems in place to identify and mitigate the effects of erosion and accretion. Drone technology allows data collection that is more efficient and accurate than conventional methods. With the right monitoring, the authorities can formulate effective policies to overcome the problem of erosion and accretion.

The Role of Drone Technology in Environmental Research

The use of drones in environmental studies brings many benefits. First, drones can access areas that are difficult to reach at a lower cost and faster time. This is particularly useful in coastal areas where the terrain can be challenging and inaccessible. Second, this technology provides a broader and detailed perspective through air shooting and topographic maps that can be analyzed further. Finally, the ability to carry out regular monitoring allows the identification of changes in real-time, which is very crucial in environmental management efforts.

Drone technology has revolutionized the way we collect and analyze data in environmental research. The use of drones has enabled researchers to collect high-resolution images and data that can be used to monitor changes in coastlines, track the movement of wildlife, and study the effects of climate change. The benefits of drone technology in environmental research are numerous, and it is an essential tool for researchers and policymakers who want to understand and mitigate the effects of environmental changes.

Methodology Used in the Study

In this study, the orthofoto data used came from Mutiara Beach in 2018 to 2020. The coastline digitization process was carried out using QGIS software. Furthermore, the analysis was carried out with the Digital Shoreline Analysis System (DSAS) on ArcGIS to get accurate data about coastline movements. This method allows more precise and detailed measurements of the level of progress and setbacks of coastlines.

The use of QGIS software and DSAS on ArcGIS enabled the researchers to accurately digitize the coastline and analyze the changes in coastline movements. The orthofoto data provided a detailed and accurate representation of the coastline, which was essential for the analysis. The use of DSAS on ArcGIS allowed the researchers to analyze the changes in coastline movements and identify the areas that were most affected by erosion and accretion.

Results of the Analysis

The results of the analysis showed that in 2018-2019, Mutiara Beach experienced the progress of the largest coastline along 43.453 meters that occurred in segment 1. In the following year, 2019-2020, the progress of the largest coastline was recorded at 35,624 meters in segment 1, while the maximum setback was 7.989 meters in segment 4. Erosion during this period reached 2,241,169 m², and the accretion reached 5,951,186 m².

The results of the analysis showed that the coastline of Mutiara Beach experienced significant changes between 2018 and 2020. The progress of the coastline was recorded in segment 1, while the maximum setback was recorded in segment 4. The erosion and accretion rates were also significant, with erosion reaching 2,241,169 m² and accretion reaching 5,951,186 m².

Conclusion

From the total analysis conducted between 2018 and 2020, the overall coastline progress was 76,457 meters with the largest progress rate reaching 29,195 meters per year that occurred in segment 1. On the other hand, the setback of the coastline reached 15,516 meters with a rate of 5,911 meters per year In segment 4. During this period, total accretion was recorded at 8,829,489 m² and erosion of 6,527,217 m².

The results of this study are expected to contribute to better coastal zone management policies, as well as preserve the coastal environment for future generations. The use of drone technology in coastal monitoring has shown to be an effective alternative to conventional methods. The benefits of drone technology in environmental research are numerous, and it is an essential tool for researchers and policymakers who want to understand and mitigate the effects of environmental changes.
