Optimizing the Utilization of Roofs of Tourism Facilities to Improve Tsunami Disaster Mitigation in the Semawang Coastal Area, Bali

This study aims to optimize the use of the roof of tourism facility buildings on Semawang Beach, Bali, as a tsunami disaster evacuation zone. The background of this research is based on the high risk of tsunamis in the coastal areas of Bali, which requires effective mitigation strategies. The method used is a descriptive qualitative approach, analyzing tourism buildings with three or more floors. Data was obtained through mapping, interviews, and direct observation, which were then analyzed using montage techniques to describe the roof's potential as an evacuation site. The results showed that buildings such as the Prama Sanur and Fairmont Hotel could be modified to accommodate thousands of people in an emergency. The conclusions confirmed that optimizing the roof as an evacuation site improves safety and maintains the local architectural identity. The benefits of this research include providing practical solutions in disaster mitigation and contributing to the development of architectural planning policies that are integrated with safety aspects. This recommendation is expected to be implemented in various tourism areas in Indonesia, creating a safer environment for tourists and local communities. The research also contributes to the coastal architectural literature by offering innovative approaches to building design responsive to disaster threats without sacrificing local aesthetics and culture.
