Abstract
One of the cities that is experiencing growth with an increase in population and rapid changes in land use is the city of Surakarta better known as Solo which is located in central Java Province. The aim of this research is to analyze changes in the vegetation density index in the city of Surakarta in 2018-2022 and analyze the accuracy of Landsat 8 imagery to map the vegetation density index in the city of Surakarta in 2018-2022. The research method used in this research is a field survey using the NDVI (Normalized Difference Vegetation Index) transformation. The research results show that there are 5 classes of vegetation density index with a range of -0.28 to 0.76. The ANOVA test showed that changes in the vegetation density index were not significant with a significance of 0.196. Based on the accuracy tests that have been carried out, Landsat 8 can be used to map the vegetation density index with an overall accuracy of 83.3% and a kappa index of 0.79. The accuracy and suitability between the map and the field shows good results and accurate image processing.
