The vulnerability is a sequence of conditions that determine whether a hazard will lead to disaster or not. Small islands easily affected by climate change, which promotes extreme waves, sea level rise, rob floods, and other disasters. The limited area of the small islands requires integrated and sustainable management. Harapan and Kelapa Islands are some of the vulnerable islands that susceptible to climate change. The problem in this research is the lack of spatial arrangement of small islands region based on climate change adaptation. This study aims to create a model of land use for spatial arrangement of small islands, especially the land area in terms of changes in land use. The methods used in this study were analysis of land use change, analysis of climate change impacts on social, economic, and environmental conditions, and predict future land use scenarios using spatial modeling. The results showed that with increasing population growth, rising sea levels, rising temperatures and salinity, and erratic rainfall patterns, land requirements for settlements increased. The conclusion of this study is the additional area in Harapan and Kelapa islands should restrict, so the mitigation and adaptation due to the impact of climate change can be done well and the risk of disasters becomes small.
