Analysis of Riparian Vegetation in Watersheds (DAS) Percut: Challenges and Solutions

Introduction

Riparian ecosystems, which are found along the banks of rivers, play a vital role in maintaining environmental balance. Unfortunately, the existence of these ecosystems is threatened by various human activities. One of the main threats is the conversion of vegetation land into built areas, which causes the loss of riparian vegetation. The Percut River, which flows through Karo Regency, Deli Serdang Regency, and Medan City, has experienced pressure on its riparian vegetation. This study aims to analyze the distribution and characteristics of riparian vegetation along the Central Percut River to downstream, conducted in December 2021 to February 2022.

Methodology

This study uses Sentinel-2 image data to analyze the characteristics of riparian vegetation with the Normalized Difference Vegetation Index (NDVI) method, Normalized Difference Built-Up Index (NDBI), Normalized Difference Built-up Water (NDWI), and modified normalized Difference Water Index (MNDWI). In addition, this research also conducts an analysis of vegetation structures with measurements in the field of seedlings, stakes, poles, trees, and non-trees.

Results

The results showed that the use of the NDVI, NDBI, NDWI, and MNDWI indexes was not optimal to characterize riparian vegetation in the Percut River. This is due to the inadequate spatial resolution of the Sentinel-2 image to capture the details of riparian vegetation along the narrow river. Analysis of vegetation structure shows that the density of trees is higher than stakes, pillars, and seedlings. This condition indicates that the natural regeneration of riparian vegetation in the Percut River is not going well.

Why Natural Regeneration is not Optimal?

Several factors can be a cause of natural regeneration that is not optimal, including:

High levels of anthropogenic disorders: Human activity around the Percut River, such as the conversion of land functions, infrastructure development, and waste disposal, can damage the habitat and inhibit the vegetation regeneration process.
Mismatch of habitat conditions: Factors such as soil erosion, changes in water flow, and poor water quality can reduce the ability of plants to grow and develop.
Lack of parent plant population: This condition can be caused by logging of trees in the past, thereby reducing the number of seeds available for regeneration.

Solution to Preserve Riparian Vegetation

Based on the results of the study, interventions are needed to preserve riparian vegetation in the Percut River. Some solutions that can be applied include:

Planting Program: Tree planting with a species that is suitable for riparian can help speed up the regeneration process and increase vegetation diversity.
Sustainable watershed management: Comprehensive management of Percut Watershed (DAS), including efforts to control erosion, water conservation, and waste management, is very important to create habitat conditions that support vegetation regeneration.
Effective monitoring system development: Comprehensive monitoring system for monitoring changes in riparian vegetation and the factors that influence it can help in evaluating the effectiveness of conservation efforts and identifying problems that arise.
Increasing public awareness: Education and socialization to the public about the importance of maintaining riparian vegetation can encourage active participation in conservation efforts.

Conclusion

This study shows that riparian vegetation in the Percut River requires serious attention to ensure its sustainability. Increased tree density without optimal regeneration indicates the need for integrated planting and management interventions. The efforts made to preserve riparian vegetation in the Percut River will not only help maintain the ecological function of the river, but will also benefit the community, such as:

Improving water quality: Riparian vegetation acts as a natural filter that can clean water from pollutants.
Control of erosion: Roots of riparian plants can hold the soil and prevent erosion along the river banks.
Wildlife Habitat: Riparian vegetation provides habitat for various types of wildlife, such as birds, fish, and mammals.
Increased aesthetic value: Healthy and lush riparian vegetation increases the aesthetic value and natural beauty around the river.

Therefore, it is important to immediately take concrete steps to preserve riparian vegetation in the Percut River.

Recommendations

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

The government and local authorities should take immediate action to preserve riparian vegetation in the Percut River.
The development of a comprehensive management plan for Percut Watershed (DAS) is necessary to ensure the sustainability of riparian vegetation.
The public should be educated and socialized about the importance of maintaining riparian vegetation.
The development of an effective monitoring system is necessary to evaluate the effectiveness of conservation efforts and identify problems that arise.

Limitations of the Study

This study has several limitations, including:

The use of Sentinel-2 image data may not be optimal to capture the details of riparian vegetation along the narrow river.
The analysis of vegetation structure may not be comprehensive, as it only includes measurements of seedlings, stakes, poles, trees, and non-trees.
The study only focuses on the Percut River and may not be representative of other rivers in the region.

Future Research Directions

Future research should focus on:

Developing a more comprehensive management plan for Percut Watershed (DAS) to ensure the sustainability of riparian vegetation.
Conducting a more detailed analysis of vegetation structure, including measurements of other plant species and characteristics.
Evaluating the effectiveness of conservation efforts and identifying problems that arise through the development of an effective monitoring system.
