<![CDATA[Abstract. The rapid development of social media has encouraged organizations to adapt their communication strategies to become more creative, interactive, and strategic. PT Kereta Api Indonesia (KAI), as Indonesia's national railway company, utilizes digital platforms, particularly Instagram through its official account @keretaapikita, as a Public Relations medium to build a positive corporate image and strengthen relationships with the public. This study aims to analyze the Public Relations strategies implemented by PT KAI's Multimedia Team in the planning, production, and evaluation of Instagram content, as well as to identify the supporting and inhibiting factors affecting these strategies. This research employs a qualitative method with a case study approach based on the constructivist paradigm. Data were collected through in-depth interviews, observations, documentation, and digital data exploration. The data were analyzed using thematic analysis to understand the meanings and interpretations of the communication actors. This study is grounded in the New Media Theory and Communication Management Theory, including the Four-Step Public Relations Process model proposed by Cutlip, Center, and Broom. The findings indicate that the Public Relations strategy is implemented systematically through content planning, production, and evaluation. The resulting content has successfully fostered two-way communication and strengthened the company's positive corporate image. However, several challenges were identified, including limited production time and the dynamic nature of public issues. Overall, the strategy is considered effective in supporting digital communication and contributing to sustainable organizational development. Abstrak.
