Green Open Space Assessment Using Vegetation Index Analysis (Case study: North Bekasi District)

Abstract

Green open space, which is planned as an arrangement of plants, crops, and vegetation of plant species conditioning, protectors, cover soil, and the other completing the instrument, plays a special role in each area that is in every city's spatial planning and serves a variety of functions, including ecological, social, cultural, and aesthetic/architectural ones, to the best advantage of the general welfare. Bekasi City is one among the locations that is currently working to enhance the amount of green open space. Based on the Bekasi City Spatial Plan (2011–2031). Bekasi must offer 6710 acres of green open space. The purpose of this study is to examine the green open space accessible in the North Bekasi District to satisfy the objectives of the spatial plan Bekasi City, which requires each region to have green open space. Landsat 7 and Landsat 8 satellite images, administrative boundaries North Bekasi were used. The vegetation index and overlay are the analytical methods employed. According to the study's findings, the degree of vegetation distribution in North Bekasi district in 2020 has reduced for the high category with an area of 185,22 hectares, particularly in the western and northern portion of the areas. The proportion of existing green open space in Bekasi City has likewise reduced by 8% between 2010 and 2020, or 159,66 hectares. The vegetation index shows 83.33% accuracy has the similar distribution of green open space in North Bekasi District for NDVI and SAVI. The Bekasi district can assist in identifying green open spaces that have been constructed with the initial concept of green open space preparation for the district surrounding utilizing from the remote sensing satellite imagery.
