Toward Sustainability: Green Road Construction in Indonesia

摘要

Road construction projects can affect directly to the degradation of the environment for causing emission, pollution, and congestion. Green road rating is the tool to measure the performance of green practices and the level of greenness on road construction projects. However, the implementation of the tool to identify how far the green concepts applied in road construction projects still lack in Indonesia. Thus, this research aims to review the extent of the implementation of green road tool in its contribution to the achievement of sustainability goals. The objectives of this research are to determine the level of the greenness of roads by clustering 12 roads and to identify the performance of each main category and subcategory related to the areas of success and the areas in need of improvement based on points obtained. Two methods used in this research are the descriptive method and cluster analysis. The research shows that the level of the greenness of 12 roads is a good adoption of green practices, in which 3 roads are awarded gold stars, and 9 roads are awarded silver stars. In addition, main categories of environment, construction, and material are more implemented than transportation and pavement among the road clusters. While the performance of subcategories namely ecological protection, economic and accessibility are more successful than resource efficiency, safety and environmental quality related to pavement and construction activities. Hence, the implementation of the green road in Indonesia has contributed more to the achievement of natural goals than human goals. Ultimately, policy recommendation is needed for improvement.
