Abstract


Climate change through increased intensity and frequency of rainfall in the oceans that cause sea level rise so that the impact on the water surface in the river. This condition has an impact on fishery cultivation in coastal areas, especially the people of Sidoarjo regency increasingly affected by climate change, especially the physical parameters in coastal areas. Sidoarjo region is divided into 5 sub-development areas of one of the 5 sub-regional development units (SSWP V) which is a coastal area with aquaculture fisheries aquaculture economic center. By using physical parameter indicators through secondary data such as area, historical flood, elevation, rainfall, mangrove, early warning system (EWS), pond area close to the river and water supply system and analyzed by AHP method then displayed in spatial map (GIS). Finally identified 4 villages with the highest physical vulnerability of Sidoarjo Regency to the impact of climate change that is Kalanganyar Village, Kupang, Tambak Kalisogo and Permisan.
