<![CDATA[Archives serve as sources of public information possessing administrative, legal, historical, and accountability value; consequently, the sustainability of their management is crucial for effective governance. Ensuring the continuity of public information relies not merely on storage but also on preservation practices capable of safeguarding archives against risks such as physical deterioration and information loss. Therefore, archival preservation should be viewed as a governance mechanism that supports the sustained availability, integrity, and accessibility of public information. This study aims to analyze the role of archival preservation as a governance mechanism in supporting the sustainability of public information at the Semarang City Archives and Library Agency. Employing a qualitative approach, the study utilizes primary data from interviews and questionnaires alongside secondary data from relevant literature and documents, which are then analyzed using a descriptive-qualitative method. The findings indicate that institutional readiness, supported by policies, human resources, facilities and infrastructure, and organizational backing, forms the foundation for archival preservation activities. Preventive and curative preservation measures are implemented in an integrated manner through storage environment control, digitization, fumigation, conservation, restoration, and documentation, thereby safeguarding archival integrity and maintaining the continuity of the information contained therein. The study concludes that archival preservation is a governance mechanism that not only protects archives as institutional memory but also reinforces the sustainability of public information through systematic, integrated management focused on accountability and the quality of public services.]]>
