Analysis of Vegetation Density in Land Cover Class in South Binjai District: Examining the Condition of the Green Open Space

Introduction

Changes in land cover in urban areas, such as in South Binjai District, have a significant impact on the existence of vegetation. The rapid development of the city requires spatial planning that pays attention to the needs of Green Open Space (RTH). This study aims to analyze the density of vegetation in various classes of land cover in South Binjai District in 2020. Analysis is carried out by utilizing Landsat 8 imagery and processing them using the * Normalize Difference Vegetation Index * (NDVI) method and guided classification.

The importance of vegetation in maintaining the quality of the environment and the balance of the ecosystem cannot be overstated. Vegetation plays a crucial role in absorbing carbon dioxide, producing oxygen, reducing air pollution, preventing soil erosion, and improving water quality. In South Binjai District, trees were found in various locations, such as mixed gardens, settlements, green lines, and river borders. However, it is necessary to add vegetation in several locations, especially the green line of roads, river borders, and outside oil palm plantations.

Methodology

This study utilizes Landsat 8 imagery to analyze the density of vegetation in various classes of land cover in South Binjai District. The * Normalize Difference Vegetation Index * (NDVI) method is used to process the imagery and guided classification is applied to identify the different classes of land cover. The results of the analysis are presented in the following sections.

Results

The results of the analysis showed that the area with the vegetation class was very tightly dominating in South Binjai District, reaching 55.56% or equivalent to 1,716.85 hectares. There are seven classes of land cover in South Binjai District, namely mixed gardens, oil palm plantations, settlements, rice fields, bushes, empty land, and water bodies. Of all these classes, oil palm plantations have the largest area with a very tight vegetation density class, which is 42.99% (1,328.50 hectares).

The Importance of Vegetation

The existence of vegetation is very important to maintain the quality of the environment and the balance of the ecosystem. Vegetation plays a role in absorbing carbon dioxide, produces oxygen, reduces air pollution, prevents soil erosion, and improving water quality. In South Binjai District, trees were found in various locations, such as mixed gardens, settlements, green lines, and river borders. However, it is necessary to add vegetation in several locations, especially the green line of roads, river borders, and outside oil palm plantations.

Recommendations and Conclusions

This study shows that although South Binjai District has an area with a high vegetation density, efforts are still needed to improve and expand vegetation in several locations. Recommendations that can be applied include:

*** Increasing Green Open Space (RTH): ** Expansion of green space along the road, river borders, and in residential areas can be done by planting trees in accordance with local conditions. *** Utilization of vacant land: ** Empty land can be maximized by planting trees or other plants to increase vegetation density. ** Socialization and education: ** It is important to socialize and educate the public about the importance of maintaining environmental sustainability and increasing awareness to plant trees.

In conclusion, the analysis of vegetation density in South Binjai District shows that there is good potential to improve the quality of the environment through the addition of vegetation. Increasing vegetation through planned and sustainable strategies will have a positive impact on the quality of life of the community and environmental sustainability.

Limitations and Future Research Directions

This study has several limitations, including the use of Landsat 8 imagery which may not provide high-resolution data. Future research directions include the use of high-resolution satellite imagery, such as Sentinel-2, to analyze the density of vegetation in South Binjai District. Additionally, the study can be expanded to include other urban areas in Indonesia to provide a more comprehensive understanding of the impact of vegetation on the environment.

Conclusion

In conclusion, this study provides an analysis of the density of vegetation in various classes of land cover in South Binjai District. The results show that there is a high potential for improving the quality of the environment through the addition of vegetation. Recommendations are provided to increase green open space, utilize vacant land, and socialize and educate the public about the importance of maintaining environmental sustainability. Future research directions include the use of high-resolution satellite imagery and expanding the study to other urban areas in Indonesia.
