Measurement of Supply Chain Management Performance on Toll Road Projects with Design and Build Contract Using SCOR and AHP Methods

Abstract

AbstractInfrastructure performance was a highlight in the World Economic Forum, thus encouraging countries worldwide, including Indonesia, to be motivated to accelerate the provision of infrastructure facilities. One of the infrastructures that continues to be improved is toll roads, and a design and build contract scheme is chosen, which in theory has the characteristics of a faster time in infrastructure provision. This project experienced delays caused by supply chain problems for the main materials, namely rebar and concrete. This study aims to measure the performance of supply chain management for rebar and concrete materials that cause project delays of 3.251%. The population in this study was 25 contractors who understood and were involved in the supply chain management process for rebar and concrete materials. This type of research is a descriptive causal study that uses a quantitative approach and uses SCOR and AHP as analytical tools. The results show that the supply chain management performance assessment for rebar and concrete materials is 64.36 out of a scale of 100. This indicates that the supply chain management performance in toll road construction projects is at an average level. This performance is much influenced by the scarcity of materials from suppliers at certain times and the design process that coincides with the construction period, causing long waiting times for adjusting the order quantity. Based on the AHP, it was found that the most dominant variables were Plan and Source. Thus, it can be concluded that the performance of delayed toll road construction projects is influenced by the performance of the rebar and concrete supply chain. For toll road projects with design and build contracts, the corrective steps must focus on Plan and Source so that the performance level increases and can avoid the risk of delays that are detrimental to service providers.
