Indonesia, as an archipelagic country with the longest coastline in the world, holds significant potential in social, cultural, economic, and environmental aspects. However, Indonesia's coastal areas are highly vulnerable to natural disasters, especially tsunamis, due to its geographic location at the convergence of four major tectonic plates, which increases the risk of earthquakes that can trigger tsunamis. Despite the high risk, coastal areas remain strategically important. Current tsunami vulnerability assessment methods do not comprehensively consider coastal physical aspects and are not fully integrated into spatial planning documents. This study aims to develop a more comprehensive tsunami vulnerability assessment model and integrate it into spatial planning documents to enhance disaster mitigation efforts in Indonesian coastal areas, particularly around Yogyakarta International Airport. This research focuses on the Aerotropolis area in Kulon Progo Regency, which is one of Indonesia's National Strategic Projects. The analysis covers various aspects affecting tsunami vulnerability, including physical, building/infrastructure, economic, social, and environmental aspects. The study employs a vulnerability assessment model with variables and indicators identified through literature review. Data used include spatial data, field observations, and spatial planning documents. Data normalization is performed by classifying data into three vulnerability categories (low, medium, and high) with a scale of 1-3. The research findings indicate that: (1) the physical aspect shows that low vulnerability category dominates the area, indicating less vulnerable physical characteristics; (2) the building/infrastructure aspect shows that most of the area has buildings and infrastructure that are not highly vulnerable; (3) the economic aspect shows that the high vulnerability category dominates the area, indicating that areas with significant economic activity are highly vulnerable; (4) the social aspect shows that the non-vulnerable category dominates the area, but there are areas with high population and tourist density; (5) the environmental aspect shows that theiv high vulnerability category dominates the area, highlighting the importance of vegetation as natural protection. The integration of tsunami vulnerability assessment into the Rencana Detail Tata Ruang (RDTR) still needs improvement to reduce disaster risk in the Aerotropolis area of Kulon Progo Regency. This research provides a foundation for developing a more comprehensive vulnerability assessment model and better integration into spatial planning to enhance tsunami disaster mitigation efforts in Indonesia.
