Mount Semeru, as the highest active volcano on the island of Java, has the potential for eruptions that could endanger the safety of residents around it. One of the villages most affected was Supiturang Village, Pronojiwo District, Lumajang Regency. The development of a web-based information system for evacuation routes is very important to minimize risks and facilitate a more organized evacuation process. The aim of this project is to design and implement a WebGIS that provides information on effective evacuation routes and population movement simulations for the Supiturang Village community. The methodology used in this project includes collecting primary data through surveys and interviews with related parties such as the Supiturang Village Government, and acquiring other data from the institution's official website. The website design was created in accordance with the National Standards Agency's guideline specifications to ensure comfort and ease of use for users. Website development is carried out using HTML technology with GeoJSON geographic data format in accordance with international standards. The result of this project is an informative and interactive website that can be accessed by the public via a variety of devices. WebGIS provides complete evacuation route maps with navigation information to the main evacuation places, also showed population movement simulations that display effective and efficient disaster mitigation scenarios based on actual conditions. The system trial was carried out using the usability testing method, with the Supiturang Village community trying the product directly, assessing it, and providing feedback as a reference for product development. It is hoped that this WebGIS product with a main menu of digital maps of evacuation routes and simulations of population movements during evacuation will be able to become an effective tool in disaster mitigation efforts and increase community preparedness.
