The rapid development of cyberspace has triggered the high spread of hoaxes related to public policies, which have the potential to undermine public trust in local government. This study aims to analyze the Government Public Relations (GPR) strategy of the Banjar City Public Relations Office in countering public policy disinformation in cyberspace. The research method used was descriptive qualitative with a case study approach. Data collection was conducted through in-depth interviews with public relations practitioners, observations of official social media platforms, and archival documentation of cyber issue reports and clarification scripts. The results indicate that the cyber issue monitoring strategy was implemented through a combination of macro digital channels (Instagram and Facebook), micro channels (a network of information agents within the citizen WhatsApp Group), and the official complaint channel "Banjar Saber Hoaks." Meanwhile, the communication strategy execution was divided into preventive and curative approaches. Preventively, the public relations office produced creative policy infographics and promoted digital literacy through the "Filter Before Sharing" movement. Critical disinformation was effectively addressed in less than 24 hours through the visual labeling of "HOAX," the development of fact-based counter-narratives, and simultaneous amplification using a one-gate communication system. Cross-agency bureaucratic hurdles were successfully mitigated through the appointment of liaison officers in each Regional Work Unit (SKPD) to expedite data validation. The study's conclusions confirm that the harmonization of proactive and responsive preventive and curative strategies effectively minimizes the destructive impact of hoaxes and maintains public trust at the local level.
