Without standardized keys, databases suffer from duplicates, orphaned records, and slow queries. A well-formed string like the above ensures each entity is globally unique within a system.

| Component | Approach | Tools & Metrics | |-----------|----------|-----------------| | Household Survey | Stratified random sampling (n = 2 400 households). | Income, asset index, food‑security score (FCS), gender‑participation index. | | Energy Monitoring | Real‑time smart‑meter data loggers (5‑min intervals). | kWh per capita, outage frequency, battery depth‑of‑discharge. | | Water‑Resources Assessment | Hydro‑logic modeling + community water‑use diaries. | Daily per‑capita water availability (L), water‑stress days. | | Ecological Mapping | Drone‑based multispectral imagery + ground truthing. | Mangrove canopy cover, NDVI change, carbon stock (t CO₂ eq/ha). | | Capacity‑Building Evaluation | Pre‑/post‑training knowledge tests & longitudinal tracking. | % increase in technical skill scores, employment outcomes. | | Policy Audit | Document review + key‑informant interviews (KII) with regency officials. | Compliance matrix (15 clauses), implementation timelines. |

Data were triangulated using mixed‑methods analysis: quantitative regressions (fixed‑effects panel models) paired with qualitative thematic coding (NVivo 14). The research design adhered to the GII’s Ethical Review Board standards (approval #ERB‑2023‑018).

Add a final digit computed from the previous characters to prevent typos. For KBJ24092531… a modulo 10 checksum would yield a single extra digit.
