It is seen from the fact that green open spaces have been replaced by the rise of hotels, malls, apartments, and other buildings. This research aims to analyze the implementation of Local Regulation of Yogyakarta City. The type of this research is empirical and normative legal research with the statute approach. By using a descriptive qualitative approach, the results show that the implementation of Local Regulation on Spatial Plans has not been effective yet. This is caused by unsynchronized substances such as the Regulations, miss communication, lack of law enforcement, and lack of cooperation among the officers.
