Internal Communication in Risk Management of PT Aluminum Extrusion Indonesia's Occupational Health and Safety System

Occupational Health and Safety (OHS) is a critical element for sustaining productive human capital and ensuring organizational goals are met, particularly in high-risk industrial environments such as aluminum extrusion. Despite regulatory frameworks, including Indonesia’s Law No. 1 of 1970 on Occupational Safety, the prevalence of workplace accidents (KK) and occupational diseases (PAK) remains a significant challenge. This study investigates the crucial role of internal communication in the effective implementation of risk management within the OHS system at PT Aluminum Extrusion Indonesia. Utilizing a qualitative, descriptive case study approach, this research aims to analyze the current state of communication channels, information flow, and engagement levels between management and workers regarding risk identification, assessment, and control measures. Findings are categorized based on communication effectiveness in transmitting risk-related information, fostering a safety culture, and ensuring participatory risk mitigation. The discussion highlights how breakdowns in vertical and horizontal communication lines can undermine comprehensive risk management and proposes a model for optimizing internal communication structures to enhance OHS performance, ultimately contributing to a safer and more productive workforce. The results confirm that a clear, timely, and bidirectional internal communication strategy is indispensable for embedding risk awareness and promoting proactive safety behavior across all organizational levels
