Improved Performance of Toll Road Projects Based on System Dynamics Integrated Life Cycle Cost Analysis Green Retrofitting

Abstract

The increasing number of infrastructure development efforts, one of which is toll roads, of course has a coordinated impact on natural damage because it causes emissions, pollution, and environmental damage. Green road rankings can be an instrument for the degree of implementation of green infrastructure and the level of reforestation in toll road development efforts. Guidelines for green road ranking SE Minister of PUPR. Number: 04/SE/M/2018 is one of the efforts to encourage the implementation of sustainable construction in infrastructure implementation. Furthermore, these green road points can be implemented on existing toll roads and meet the sustainability criteria. This study aims in the innovation of Dynamic Model Implementation and Life Cycle Cost Analysis on Green Infrastructure-based Toll Road works which will result in Cost Efficiency and add value to Toll Roads. For data processing, we used SPSS (Statistical Package for the Social Sciences), a statistical analysis obtained from a questionnaire filled out by experts. From this process, we got the 10 best factors which are: 1. Authority to administer toll roads; 2. Reduction of air/dust pollution; 3. Greening; 4. Provision of access and public transportation facilities; 5. Recycle construction waste; 6. Renewable energy and application of innovation; 7. Renewable energy street lighting; 8. Modeling of dynamic systems; 9. Initial Retrofitting Costs; 10. Period of analysis. From the green retrofitting implementation scenarios, the optimistic scenario shows the highest rating score and the fastest return on investment in 3.92 years, with the toll road retrofitting cost of IDR 378,700,000,000.
