Soekarno-Hatta Airport is the main gateway for international flights, particularly to Greater Jakarta. Currently, it serves more than 44 million passengers per year, which causes accessibility problems due to the high volume of vehicles. A toll road still remains the main access to the airport, and in peak hours there is congestion and time-travel uncertainty. Soekarno-Hatta International Airport Rail Link (SHIARL) is an alternative mass-transportation project to provide accessibility and mobility for people and goods to the airport. So far, the project is still unable to attract private investors due to a lack of technical and financial feasibility. This research aims to develop a conceptual design of SHIARL by using the value-engineering approach for a comprehensive study to realize this project. This research used quantitative and qualitative methods through questionnaire surveys distributed to various stakeholders related to the project, and focus group discussion (FGD). The results identified additional functions for innovation through the integration of Mass Rapid Transit (MRT), flood control, telecommunications, and development in the downtown area of the station. These functions were then analyzed by using life-cycle cost analysis to show the value for money of the project.
