Life cycle cost analysis in system dynamic modeling on Indonesia's green toll road

Abstract

The increasing number of toll road construction projects certainly has a direct impact on environmental damage because it causes emissions, pollution, and congestion. The green road rating is a tool to measure the performance of green practices and the level of reforestation in toll road construction projects. However, the implementation of tools to identify the extent to which green concepts are applied in road construction projects is still lacking in Indonesia. Therefore, this study aims to examine the extent to which the implementation of green road tools contributes to the achievement of sustainability goals. This study aims to determine the green level of the toll road and identify the performance of each main category and subcategory related to areas of success and areas that need to be improved based on the points obtained. From these categories, it is then modeled with System Dynamics to determine the dependencies and the resulting life cycle costs. The tentative hypothesis is that improving road quality by implementing green roads on toll roads and modeling system dynamics can reduce life cycle costs. Therefore, the implementation of greener roads is needed in Indonesia for environmental sustainability and life cycle cost savings. Finally, policy recommendations are needed for improvement.
