This study aims to analyze the industrial extension communication strategies employed within the Halal Certification Program for food-based Small and Medium Industries (IKM) in Balangan Regency. A qualitative approach with a case study design was adopted. Data were collected through in-depth interviews, observation, and documentation, and subsequently analyzed using the interactive model developed by Miles, Huberman, and Saldaña. The results indicate that the effectiveness of the communication strategy is determined by systematic communication planning, collaboration between industrial extension officers and Halal Product Process Facilitators (PPH), the formulation of adaptive messages, and the utilization of both interpersonal communication and digital media. These findings extend the application of John Middleton’s Communication Planning Theory by integrating VRIO and PESTEL analyses to explain extension communication strategies within the context of halal certification policy implementation. Keywords: Communication Strategy, Halal Certification, Industrial Extension, PESTEL, VRIO.
