Sistem Informasi Geografis Visualisasi Data Stunting pada Balita Berbasis Web di Desa Sumberwaru

Stunting is a chronic nutritional problem in toddlers that affects physical growth and cognitive development. In Sumberwaru Village, stunting data management is still done manually through Posyandu notebooks and written reports, which causes reporting delays and the risk of recording errors. This study aims to develop a web-based Geographic Information System (GIS) to visualize stunting data in toddlers to support more effective data management, monitoring, and spatial analysis. This study uses a Research and Development (R&D) approach with a Waterfall development model, consisting of needs analysis, system design, implementation, testing, and maintenance. The system was developed using JavaScript and MySQL and tested by 50 users consisting of Posyandu cadres, KPM officers, and village staff. Black-box testing showed that all main functions of the system operated successfully, while usability evaluation using a Likert-scale questionnaire produced an average score of 97.12%, indicating that the system is easy to use and useful for operational activities. The developed system enables faster and more structured management of toddler and stunting data and provides digital map visualization to identify areas with high stunting prevalence.
