The Government of West Nusa Tenggara (NTB) has officially launched the Metadata NTB Satu Data – NTB Satu Data Sectoral Data Collection Guidelines 2025, a strategic reference for subnational data collection and management. This milestone strengthens the implementation of Indonesia’s One Data Policy, as mandated by Presidential Regulation No. 39/2019 and Minister of Home Affairs Regulation No. 5/2024. Featuring 1,961 sectoral datasets complete with definitions, methodologies, standards, and reference codes, the publication ensures data credibility, transparency, and accountability. By providing reliable metadata, NTB supports evidence-based planning and budgeting, enhances accountability, and promotes inclusive and targeted public services. Developed by the NTB One Data Forum with support from the SKALA Program (Australia–Indonesia Partnership to Accelerate Basic Services), this metadata serves as a strong foundation for realizing NTB’s vision of becoming a Prosperous and Globally Connected Archipelagic Province. The book is only available in Bahasa Indonesia.
