Air Tawar Barat Village is located in North Padang District, Padang City which is directly adjacent to the Indian Ocean in the west, so there is a risk of a tsunami disaster. The current evacuation route, which is one of the efforts to overcome the tsunami disaster, seems to be still ineffective to use because the distance that must be covered is 3-5 km in less than 30 minutes. This study aims to determine the direction of an effective evacuation route and then make a comparison with the evacuation route that has been determined by the Government. The method used is Network Analyst. The results of this study obtained 3 alternatives to make evacuation more effective. The alternative is to make access roads around Jalan Gajah to go to P-TES in the UNP area. Alternative 2 is to make P-TES in the parking lot of the Air Tawar Health Center so that people around the river mouth can evacuate faster because they are closer. Alternative 3, the community around the North Padang Police Sector can evacuate by heading to P-TES on Jalan Polonia, Air Tawar Timur Village to stay away from the beach. The three alternatives make the evacuation time to 10 minutes by heading to 26 P-TES. In addition, the evacuation map as a result of the analysis is more effective because the route has a route that is more likely to be taken by the community compared to the government evacuation map.
