One Data Indonesia: A Retrospective Analysis of Data Interoperability in Declaring Regional Planning and Development

Regional development in Indonesia is key to improving people’s welfare and regional progress. However, many local government applications have not been integrated, leading to fragmented data and suboptimal planning analysis. The purpose of this research is to explore the implementation of the Electronic-Based Government System (EGBS/SPBE), and the challenges faced, as well as its impact on regional development planning. The novelty of this research lies in the in-depth analysis of how the One Data Indonesia regulation facilitates data interoperability and standardization at the regional level. The research methodology uses a qualitative approach through interviews, group discussions, and document analysis. The data analysis technique involved thematic coding to identify patterns and main themes. The results show that these regulations facilitate data interoperability and standardization, although technical and administrative challenges remain. Case studies in Central Java and Jember District show improved integration of sectoral data, such as education. The research concludes that the implementation of Satu Data Indonesia provides a solid foundation for improving the efficiency of public services, strengthening bureaucratic transparency, and supporting more accurate data-driven decision-making that can improve the effectiveness of SPBE and support sustainable and responsive regional development. This research provides important insights into the complexities of data integration in local government, as well as contributing to national efforts to improve data governance and public services.
