Land Use Spatial Model for Building Based on Availability and Capacity of Land in Territory of Coastal City (Case Study: Palu City)

Abstract

The arrangement of coastal ecological space in the coastal city area aims to ensure the sustainability of the system, the availability of local natural resources, environmental health and the presence of the coastal ecosystems. The lack of discipline in the supervision and implementation of spatial regulations resulted in inconsistencies between urban spatial planning and land use facts. This study aims to see the inconsistency between spatial planning of the city with the real conditions in the field so it can be used as an evaluation material to optimize the planning of the urban space in the future. This study used satellite image interpretation, spatial analysis, and projection analysis using markov cellular automata, as well as consistency evaluation for spatial planning policy. The results show that there has been a significant increase of open spaces during 2001-2015 and physical development was relatively spreading irregularly and indicated the urban sprawl phenomenon. There has been an open area deficits for the green open space in 2015-2031, such as integrated maritime, ports, and warehousing zones. Several islands in Makassar City are predicted to have their built-up areas decreased, especially in Lanjukang Island, Langkai Island, Kodingareng Lompo Island, Bone Tambung Island, Kodingareng Keke Island and Samalona Island. Meanwhile, the increase of the built up area is predicted to occur in Lumu Island, Barrang Caddi Island, Barrang Lompo Island, Lae-lae Island, and Kayangan Island. The land cover is caused by the human activities. Many land conversions do not comply with the provision of percentage of green open space allocation in the integrated strategic areas, established in the spatial plan. Thus, have the potential of conflict in the spatial plan of marine and small islands in Makassar City.

Suburban Development: Spatial and Physical Transformation of Residence as a Determinant of Settlement Densification in Makassar City, Indonesia

“…The dynamics of land use change or built-up area cover in Makassar City increased by 13.92% from 7,849 ha in 2006 to 10,294 ha in 2016, or 80.37% of the total area of Makassar City in 2031 [14]. The growth of the residential area of Bumi Tamalanrea Permai and its surroundings from the 1989-1999 period occurred when builtup space reached 57.36 ha, or 21.65%, and increased to 114.49 ha, or 43.20%, in the 2000-2018 period, meaning that there was a growth in residential units; residence reached 171.85 ha, or 64.85%, for 29 years [15].…”
