<![CDATA[The Family Planning - Integrated Health Service Post (Posyandu) plays an important role in providing primary health services at the community level in Indonesia, especially in monitoring maternal and child health. However, traditional management and performance evaluation of Posyandu often faces challenges such as limited data accuracy, inefficient reporting, and a lack of integrated monitoring tools. This research aims to develop a Geographic Information System (GIS)-based application to improve the mapping and performance assessment of Posyandu. In contrast to previous GIS health mapping systems, this study makes a unique contribution by integrating automated performance classification based on Posyandu success indicators as well as real-time analytics to support more responsive decision-making. This research uses the Research and Development (R&D) method with the Waterfall approach. The resulting application integrates performance dashboard features, GIS-based location mapping, and data management modules. Blackbox Testing and User Acceptance Test (UAT) are conducted to ensure the functionality and reliability of the system. The functional test results through 10 black box test scenarios show a 100% success rate, while the UAT results achieve an average score of 100% confirming the usability of the system. The app allows cadres to manage data efficiently and provide transparent information to the health office. This study concludes that this GIS-based application significantly improves data management and performance visualization, thereby strengthening the role of Posyandu in public health services.]]>
