Emergencies can occur anytime, anywhere, and to anyone. The local government offers an application called "Panic Button" as a solution to these problems. This application aims to help people who experience or see emergency conditions so that they can be followed up by the authorities. However, this application has not been targeted at disability users. The procedure for using this application still has weaknesses that make it difficult for users with hearing loss, especially when an emergency event is confirmed. Normally, emergency event confirmation uses telephone calls to the incident reporter (user). This confirmation method is a big problem for those users with disabilities to be able to confirm the details of emergency events. In this research, a user interface re-design was carried out at the application interface to be able to accommodate the needs of users. The interaction re-design is built using the User-Centered Design (UCD) method to produce a design that matches the users characteristics and limitations. The resulting prototype was evaluated using the USE Questionnaire method and results in a usability value of 87% with a very good category after the 3rd iteration. These results indicate that the results of the re-design that have been done are quite easy to learn and use by users.
