Change and Prediction of Green Open Space Land Use in Depok City

Perubahan dan Prediksi Penggunaan Lahan Ruang Terbuka Hijau di Kota Depok

Abstract

Urban development tends to marginalize GOS (Green Open Space) as an urban ecological function. In the 1996-2000 period, Depok City placed the built-up area as the dominant land use and the land use that has the function of GOS was reduced by 87 ha. For planning and controlling land use change, information on changes and prediction of GOS needs to be known. This study aims to identify GOS land use in 2006, 2013 and 2019; to predict GOS in 2031 and to analyze the GOS needs. The analytical methods used include interpretation of GeoEye images, overlapping land use maps, land use prediction with CA-Markov and assessment of GOS needs. The results show that built-up area increased significantly by 3,579 ha in the 2006-2019 period, while GOS decreased by 167 ha. In 2019, GOS in the city of Depok has not been met the minimum requirement of 30% of the total area as mandated by the Spatial Planning Law no. 26 of 2007 and still requires 3,087 ha of RTH. This shortage will increase in the future because the prediction of GOS in 2031 decreases and this condition makes the need for GOS in Depok City increase to 3,139 ha.
