The urban forest is a green area in urban areas overgrown with woody vegetation and provides physiological, sociological, economic, and aesthetic benefits for urban communities. Unfortunately, urban forest change is still happening everywhere, especially in Jabodetabek Megacity until now, and is a problem because the arrangement of cities is more in favor of economic interests. This is considered to be the main cause of runoff, flooding, and erosion which in turn causes reduced air supply and increased air pollution which can change the microclimate of urban areas. Research is needed to detect how many changes in urban forests in Jabodetabek Megacity are so that the changes can be controlled
