Rural development has become a strategic pillar in Indonesia’s national agenda following the enactment of Village Law No. 6 of 2014, which empowers villages to manage resources and finances independently. Despite the significant increase in village fund allocations, challenges such as limited administrative capacity, lack of transparency, and data fragmentation persist, particularly in regions like Glumpang Baro Sub-District. This study developed a Geographic Information System (GIS) designed to map and monitor infrastructure projects funded by the village fund program. The system was constructed using the waterfall development model, employing PHP as the main programming language, MySQL as the database management system, and Google Maps API for spatial visualization. Data were collected through observation, documentation, and literature analysis to ensure system relevance and accuracy. The resulting web-based GIS enables centralized storage, real-time access, and transparent reporting of development activities for both administrators and the public. Empirical evaluation shows substantial efficiency improvements: operational costs decreased by 86%, data entry time by 80%, and workforce requirements by 40% compared to the previous manual approach. Beyond technical functionality, the system fosters participatory governance, accountability, and informed decision-making, providing a scalable model for digital transformation in local development management.
