Design and implementation of Awas Guncang: A mobile app for future dissemination of InaEEWS

Indonesia is a country with a high level of seismic risk, making an effective Earthquake Early Warning System (EEWS) crucial. The Agency of Meteorology, Climatology, and Geophysics (BMKG) has been developing the Indonesia Earthquake Early Warning System (InaEEWS). This system requires a fast and reliable dissemination channel to reach the general public. This research aims to design and implement a mobile application named “Awas Guncang” as a future dissemination solution for InaEEWS. The application was developed using the Flutter framework. The notification delivery method relies on Firebase Cloud Messaging (FCM), a cross-platform push notification service, for real-time alert transmission, even when the application is terminated. This research yields a functional mobile application prototype capable of receiving, processing, and displaying earthquake early warning notifications following the designed workflow. The application is proven to deliver full-screen intent notification alerts based on specified Peak Ground Acceleration (PGA) thresholds, a measure of earthquake shaking intensity. Therefore, “Awas Guncang” demonstrates its potential as an effective and responsive platform for disseminating InaEEWS information, which can enhance public preparedness for earthquake disasters in Indonesia.
