Introduction

The Percut watershed, located in a region of great natural beauty, plays a vital role in the management of natural resources and the environment. In order to better understand and manage this watershed, a study was conducted to identify the type of land cover and evaluate the use of forest areas in the area using Sentinel-2 satellite imagery. This study aims to provide a comprehensive analysis of the Percut watershed, highlighting the importance of land cover classification and the use of remote sensing technology in understanding and managing the environment.

Background

The Percut watershed is a critical component of the river basin, providing essential ecosystem services such as water filtration, soil conservation, and habitat creation for various species. However, the condition of land cover in this watershed has a significant impact on the overall health of the ecosystem. In recent years, there has been a growing concern about the degradation of land cover in the Percut watershed, which has led to a decline in biodiversity and ecosystem sustainability. Therefore, it is essential to conduct a thorough analysis of the land cover in this watershed to identify the type of land cover and evaluate the use of forest areas.

Methodology

The study used Sentinel-2 satellite imagery to classify the land cover in the Percut watershed. The Sentinel-2 satellite is a high-resolution satellite that provides detailed images of the Earth's surface, making it an ideal tool for land cover classification. The study used a combination of supervised and unsupervised classification techniques to identify the different types of land cover in the watershed. The results of the classification were then evaluated using various accuracy metrics, including overall accuracy and Kappa accuracy.

Results

The results of the study indicate that the forest is the most dominant land cover in the Percut watershed, covering an area of 95,562.78 ha or 27.93% of the total area. The forest area that is still maintained is found in the natural reserve area of 4,779 ha. This shows that although there is a threat to land cover, there are still protected areas to maintain biodiversity and ecosystem sustainability.

Furthermore, the analysis shows that the slope class of more than 45% is dominated by forests with an area of 37,320.87 ha. This indicates the importance of forests in maintaining soil stability and reducing the risk of erosion in areas with steep slope. In addition, areas with elevation of more than 900 meters above sea level are also dominated by forests, covering an area of 30,488.93 ha. This height often becomes a habitat for various species of typical flora and fauna, so that the existence of forests in this region is very important to maintain the balance of ecosystems.

Discussion

The results of this study provide a clear picture of the condition of the ecosystem in the Percut watershed, as well as the challenges faced in its management. With accurate information, decision makers can design more effective and sustainable management strategies, including supervision of changes in land use, preservation of forest areas, and the development of policies that support environmental sustainability.

The study also highlights the importance of monitoring land cover routinely using remote sensing technology such as Citra Sentinel-2. This not only helps in understanding the current conditions but also in planning the actions needed for conservation and utilization of wise natural resources. Thus, the results of this study contribute positively to the management of the Percut and Welfare of the Community that depend on the ecosystem.

Conclusion

In conclusion, this study demonstrates the importance of land cover classification and the use of remote sensing technology in understanding and managing the environment. The results of this study provide a comprehensive analysis of the Percut watershed, highlighting the importance of forests in maintaining soil stability and reducing the risk of erosion. The study also emphasizes the need for routine monitoring of land cover using remote sensing technology to ensure the sustainability of the ecosystem.

Recommendations

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

Continued monitoring of land cover using remote sensing technology to ensure the sustainability of the ecosystem.
Preservation of forest areas to maintain biodiversity and ecosystem sustainability.
Development of policies that support environmental sustainability and the conservation of natural resources.
Supervision of changes in land use to ensure that land use changes do not have a negative impact on the ecosystem.

By implementing these recommendations, decision makers can design more effective and sustainable management strategies for the Percut watershed, ensuring the long-term sustainability of the ecosystem.
