The distribution of green open space in Jember City area based on image landsat 8-OLI

Green open space has an important role in the ecological balance of urban areas with a minimum area that must be approved by 30%. Jember City Region consists of Sumbersari, Kaliwates, and Patrang Sub-Districts which are designated as Regional Activity Centers with four main functions. The distribution of green open space in Jember City can be known quickly and accurately by using remote sensing imagery. The purpose of this study is to study and analyze the distribution of green open space in the city of Jember specifically in the Sub-Districts of Kaliwates, Sumbersari, and Patrang whether it has met the minimum requirement of green open space construction of 30% of the total area. The analysis carried out with the help of Landsat 8-OLI imagery recording 10 June 2018. The method used is the NDVI classification. The results showed that classification of land use using vegetation index is good because it can minimize errors. The total area of determined vegetation green space based on NDVI classification is 23.70 km(2) or around 24.5% of the total area.
