Palu City, a coastal city in Eastern Indonesia, holds significant potential for development due to its abundant natural resources. However, the 2018 earthquake and tsunami caused extensive damage to both land and marine environments, necessitating a strategic approach to environmental restoration and economic recovery. This study aims to guide coastal land use in Palu City by applying the Analytical Hierarchy Process (AHP) technique and Geographic Information System (GIS) technologies. Remote sensing and GIS tools are employed to analyze land cover and process spatial attribute data. The methodology includes field surveys, AHP analysis, and spatial integration using GIS. The results show that land use planning in Palu’s coastal areas should prioritize biophysical, economic, and social considerations. Key recommended uses include residential development, tourism, and trade zones. The study also highlights the importance of incorporating disaster vulnerability data into the planning process, given the city’s susceptibility to natural hazards. Careful mapping and land designation, informed by past disaster impacts, are essential to ensure sustainable resilient coastal development in Palu.
