Riski Rahmat focused on enhancing data integrity within the Diah082/izin repository by establishing a Single Source of Truth for the IP address list. Over the course of one month, Riski corrected and updated IP address entries, normalized timestamps, and removed incomplete data to ensure reliable configuration management and data management. The work involved disciplined Git-based collaboration and careful data cleansing, resulting in a more consistent and auditable logging source. Although no new features were added, the targeted bug fix reduced data drift across dependent systems and improved monitoring accuracy, demonstrating a methodical approach to maintaining high-quality operational data.
