This research aims to explore strategies to improve the productivity of loading and unloading activities at PT. Terminal Petikemas Nilam Surabaya through the implementation of the Electronic Rubber Tyred Gantry (E-RTG) system. Although the E-RTG system has not yet been implemented at PT. Terminal Petikemas Nilam Surabaya, its application is considered a potential solution to support efforts in enhancing loading and unloading productivity. E-RTG is a container handling equipment that utilizes sensor technology and battery-powered electricity as a replacement for conventional fuel. This study employs a qualitative approach with data collection techniques including interviews with RTG operators and the HSSE team, as well as documentation. The data analysis method used is SWOT analysis to identify the strengths, weaknesses, opportunities, and threats associated with the E-RTG system. The research findings indicate that the implementation of E-RTG has the potential to significantly improve loading and unloading productivity. To ensure successful implementation, PT. Terminal Petikemas Nilam requires several strategies such as infrastructure development, human resource training, seeking investment, and updating the port's digital security systems. With proper strategic planning, the implementation of E-RTG is expected to assist PT. Terminal Petikemas Nilam in future adoption efforts and contribute to increasing the productivity of loading and unloading operations at Terminal Petikemas Nilam Surabaya.
