Siaga - Emergency App
About
Siaga was born from a personal experience of living in a new city, where safety became a growing concern. As a student who moved to Yogyakarta, I faced firsthand the rising threat of incidents such as "klitih" which is defined as a random, violent street attacks that left many people, including students, feeling unsafe.
This project was designed to provide an immediate, reliable solution for those in need of emergency services, such as the Police, Ambulance, and Firefighters. The app integrates live GPS location, video calls, and a panic button, aiming to minimize the time it takes to connect with authorities and send help.
My role focused on designing a UI that was intuitive and easily accessible, even in panic-inducing situations. The challenge was ensuring that users in high-stress conditions could navigate the app without confusion or delay, with features such as one-tap assistance and real-time tracking.

Challenge
The major challenge of Siaga’s design was creating an interface that was simple enough for users to operate during emergencies while incorporating complex features like GPS tracking, video calls, and live location sharing.
Understanding user behavior in stressful scenarios was critical to designing a solution that allowed users to quickly call for help with minimal navigation. Another challenge was integrating multiple services, like police and healthcare, into a unified system without overloading the user with too much information at once.
Responsibility
As the UI/UX designer, I led the creation of an emergency interface that could deliver simplicity, clarity, and speed. My responsibilities included designing wireframes and prototypes, focusing on user-friendly navigation and seamless integration of the app’s key features. I conducted usability tests with potential users to understand how they would interact with the app during crises and adjusted the design based on their feedback.

Process
User Behavior Research: We studied how users behave during emergencies, gathering insights on how they would interact with an app like Siaga under stress. This research informed my design decisions, ensuring that the layout and navigation were intuitive and fast.
Wireframing & Prototyping: I developed wireframes that minimized the steps needed to access critical features. The design featured large, easily recognizable buttons for emergency services, and all actions were streamlined to reduce any potential confusion or delays in navigation.
Usability Testing: To ensure the app was practical and effective, I conducted usability tests where users simulated emergency scenarios. This allowed me to refine the design based on real-world stress conditions, ensuring users could easily access GPS tracking, video calls, and other emergency functions.
Design Iteration: Based on testing feedback, I simplified the layout further, reducing cognitive load by using color coding for different services and providing clear, actionable buttons that users could access instantly.
Key Takeaways
The Siaga project taught me the importance of designing for extreme usability, particularly in high-pressure situations. Simplifying the interface while ensuring critical features were readily accessible was key to the project’s success. This project reinforced the idea that user-centered design, backed by real-world usability tests, is crucial for building systems that people will rely on in emergencies.
