Abstract

In facing the increasingly complex challenges of the port industry, it is important to understand the contribution of technology and green practices in improving efficiency and sustainable operational performance. This study aims to examine the effect of IoT-based Service Management System (X1), Cloud ERP (X2), and Green Operation Management (X3) on Sustainable Operational Performance (Y), with Operational Efficiency (Z) as a mediating variable at Lamong Bay Terminal. Data were collected through questionnaires distributed to workers who have implemented IoT, Cloud ERP, and green operations management practices. Data analysis used the Structural Equation Modeling-Partial Least Squares (SEM-PLS) method to evaluate the relationship between variables. The results showed that IoT, Cloud ERP, and Green Operation Management have a positive influence on operational efficiency with coefficient values of 0.299; 0.166; and 0.099, respectively. Operational efficiency also contributes positively to the sustainability of operational performance with a coefficient value of 0.263. These findings suggest that the implementation of modern technology and environmentally friendly practices can support improved operational efficiency and sustainability. These results provide strategic insights for Teluk Lamong Terminal to optimize operational efficiency and sustainable performance

Abstract

The rapid increase in Ro-Ro (Roll-On/Roll-Off) vessel and vehicle traffic at Tanjung Perak Port, Surabaya, has exposed critical inefficiencies in port operations, particularly at key berths such as Jamrud Utara and Jamrud Selatan. These inefficiencies manifest as prolonged queuing times for Ro-Ro vessels and land-based vehicle congestion, leading to delays in cargo handling and increased operational costs. This study aims to evaluate the operational performance of Ro-Ro terminals based on queue time indicators for both Ro-Ro vessels and vehicles. Employing a quantitative descriptive approach, the research integrates the M/M/c queuing model and Fishbone Diagram analysis to identify systemic causes of operational delays and overcapacity. The study reveals that berth utilization rates exceed 75%, indicating saturation, while limited buffer zones and disorganized traffic flow exacerbate vehicle queues. As a case study, the findings offer data-driven insights and practical recommendations, including schedule optimization, dedicated traffic lanes, and infrastructural upgrades to mitigate congestion. The proposed framework not only enhances service efficiency at the port but also contributes to broader logistics performance in Eastern Indonesia. By combining classical queuing theory with root cause analysis, this research introduces a methodological synergy that can be replicated across other Ro-Ro terminals facing similar challenges. The findings underscore the urgent need for integrated port traffic management and infrastructural adaptability in response to growing maritime logistics demands.
