This study presents the development of an Android-based application, Sitekstagi, aimed at monitoring stunting determinants during the COVID-19 pandemic by centralizing questionnaire data collection. Utilizing the software development life cycle (SDLC) method, the application has been tested for usability and functionality, showing positive results in ease of use and performance. The application is intended for health workers to facilitate data collection and analysis, with future enhancements planned to incorporate artificial intelligence for stunting detection.
