"The infrastructure of the transportation system plays an important and strategic part in the development of a country and serves to support economic progress by enabling the mobility of citizens and the distribution of goods from one region to another. However, communities have unequal access to the system and there are gaps in the regional infrastructure in Indonesia, leading to the requirement for a mapping of all 33 provincial capitals. In this study, we reviewed provisions for road, sea, air, and rail travel. The mapping result is expected to determine the pattern and the prioritization needed for future infrastructure development. A literature review was performed to establish assessment indicators for the mapping. The weighting of each indicator was based on a survey of stakeholders in transportation sectors, which was then analyzed using the Analytical Hierarchy Process. After weighting was completed, the infrastructure of each provincial capital was assessed to determine ratings from the highest to the lowest rank. Jakarta, Medan, Bandung, Surabaya, and Semarang obtained the highest rankings, while Manokwari, Serang, Mamuju, Ternate, and Palangkaraya were at the bottom. This result shows that provincial capitals in western Indonesia had better assessment results than those in the east. Therefore, improvements to the transportation infrastructure of the latter cities should be prioritized."

"Sunda Strait Bridge (SSB) is one of the mega-intifastructure projects offered by the Indonesian governrneni' and is expected to contribute to national economic growth by bridging cconofnic connectivity between two major islands in Indonesia. At tirst, SSB construction was ot`t`ered as a USS lt) Billion project in Etll 0 and revised into a USS 25 billion project with additional scope of work, i.e. industrial area development along the site, in 20li. Yet, it was still unattractive to private investors due to lacleing of technical and Hnancial feasibility. Thus, Value Engineering (VE) approach is used to increase and improve the project’s teasibility by generating innovative ideas. Innovation through additional 'ninctions lor Sunda Strait Bridge development is comprising of: 1) Development of renewable energy-based power plant by using tidal and wind power; 2) Integration of oil and gas pipelines; (3) Fiber optic pipelines; 4) Tourism Development in Sangiang Island which may be accessed by using either road bridge or hanging train; 5) Development of industrial area. The life cycle cost analysis by IRR and NPV approaches confirmed that Sunda Strait Bridge development with additional functions increased the intcmal late of return of the overall project up to 7.26% and had a positive NPV value."

"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 volurne of vehicles. Toll Road still becomes the main access to the airport and in peak hours. these high volunics of vehicles create congestion leading to time travei uncertainty. Soel"
