A multimedia system for best-first search evacuation routes in tsunami mitigation emergencies on Sanur Beach, Bali, Indonesia.

The article focuses on the development of a multimedia system using the best-first search algorithm to optimize tsunami evacuation routes at Sanur Beach, Bali, Indonesia, a popular tourist destination vulnerable to tsunamis. The study identifies five major crowd locations and maps evacuation routes to three zones: High-Risk, Low-Risk, and Safe Zones, with estimated evacuation times ranging from 10 to 27 minutes to Low-Risk Zones and 25 to 60 minutes to Safe Zones. The system integrates real-time GPS navigation, emergency alerts linked to Indonesia's official tsunami warning network, and accessibility features for vulnerable populations. While evacuation times at most locations meet international benchmarks, some areas require improved infrastructure or additional assembly points to enhance safety. This approach aims to improve public preparedness and evacuation efficiency for both residents and tourists in tsunami-prone coastal areas.
