Integration of the Spatial Planning of Land and Sea: Case Study on Coastal Bontang

Coastal management approach with a territorial approach is important for the sustainability of coastal management because at that level there is an incorporation of highly complex interaction of ecological, social and economic phenomena. Sustainable coastal utilization must look at two aspects of territoriality, namely the spatial aspects of land (terrestrial) and the spatial aspects of the Sea (coastal waters).  This study attempts to build a model of the zoning plan for Bontang City’s coastal areas by integrating the issues and potentials—ecological, social, and economic—on the land and in the coastal waters. The analytical tool used in this research is Geographic Information System (GIS) and a decision support tool of Marxan with Zone. Several previous studies had used Marxan with Zone, but their planning units covered only a maximum of three allocation zones of uses. This study is an effort to develop a planning unit of more than three planning zones. In addition, in this research, the input data used to run Marxan with Zone is based on the perspectives of stakeholders.
