Spatial Pattern Changing Analysis of Built-up Due to The New Era of Aerotropolis in Kulon Progo, D.I. Yogyakarta

Abstract

Built-up is artificial land use representing urban-oriented activities according to the sector developed in the aerotropolis, the development concept of city activity centered on the globally networked economy’s airport. The growth of unplanned built-up often caused environmental deterioration. Therefore, the impact of the emerging of a new growth center to the growth characteristic of the built-up requires to be analyzed. This research aimed to examine the growth and spatial distribution characteristics of built-up to mitigate the undesirable impact on the environment in the early phase of aerotropolis in Kulon Progo. The growth was analyzed using the spatial intersection of land use/land cover. The distribution orientation growth was carried out by weighted mean center and spatial standard deviational ellipse. The results demonstrate that annual growth of built-up increased from 55.35 ha per year in 2010-2015 to 69.83 ha per year in 2015-2020. Dryland agriculture was the most land use converted to built-up after aerotropolis era. The direction of built-up growth also shifted from northwest to southwest, and the distance between the airport and the mean center was getting closer. Therefore, land use planning policy need to refer to this pattern changing to preserve environmental sustainability while achieving economic growth.
