Authors - Melly Azwari, Abdurrahman Faris Indriya Himawan Abstract - Operational sustainability is a strategic imperative for ports, requiring efficiency, cargo integrity, environmental responsibility, and stakeholder trust. This study investigates how integrating halal and sustainable supply chain practices influences operational sustainability at Tanjung Priok Port, Indonesia, using the Triple Bottom Line perspective. Halal supply chain employs physical segregation, traceability via barcode/RFID, and segregated waste handling, while sustainable supply chain implements energy efficiency, emission reduction, and green logistics practices. A quantitative associative design was employed with 169 purposively sampled port logistics operations respondents. Data were analyzed using multiple linear regression. Results indicate that both halal supply chain (B = 0.248; t = 4.016; p < 0.001) and sustainable supply chain (B = 0.702; t = 10.281; p < 0.001) significantly and positively affect operational sustainability, with sustainable supply chain emerging as the dominant predictor. Jointly, the integration explains 60.5% of the variance (F = 129.567; p < 0.001). These findings offer practical insights for port managers seeking responsible, resilient, and integrated port operations.
