Background: Tidal flooding is a significant problem in the coastal areas of Semarang City, due to climate change and environmental pollution issues. Method: The research method involved direct observation and interviews with homeowners to collect primary data, as well as scoring analysis based on four main indicators. This study used a structural indicator-based scoring analysis approach to assess the physical vulnerability of houses to tidal flooding. Findings: Tambakrejo area, which is a coastal area, also experiences periodic inundation due to sea level rise. The physical vulnerability of houses in this area is influenced by various factors, such as building materials, building age, floor height, and building height. The results show that most houses in Tambakrejo have a moderate level of vulnerability, with building materials and age as the main causes. Houses with wooden materials and more than 20 years old are more vulnerable to damage from inundation, while multi-storey houses and those with higher floors have better resilience. Conclusion: The study highlights that building materials and age are key factors affecting the physical vulnerability of houses to tidal flooding in Tambakrejo, Semarang City, and suggests consideration of structural indicators in flood risk mitigation. Novelty/ originality of this article: The novelty of this study lies in using a structural indicator-based scoring analysis to assess the physical vulnerability of houses to tidal flooding in Tambakrejo, highlighting building materials, age, and floor height as key factors.
