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.

The identity of the city is formed of understanding and meaning (image) of something that exists or ever existed/attached in the city or the introduction of physical and non-physical objects that are formed in time to time. The city's identity is one of an essential goal to improve the environmental conditions in the future. This study aims to reveal the identity of the Donggala city based on aspects of forming integrated urban identity as a uniqueness overview and its hallmark. The study emphasizes on the descriptive and explanation design through qualitative and quantitative approach conducted by using survey methods. The results showed that there are five aspects of identity-forming of the integrated city: the geographical aspects, historical aspects, accessories aspects, humanist aspects, and the strategic aspects. The best identity in representing Donggala city based on those five aspects is dominated by the disclosure of the identity as the city tourism which emphasis on marine and historical tourism.
