Increasing competition encourages companies to seek pressing construction waste. The suppression efforts waste is very closely related to lean concepts which are <br /> <br /> <br /> developed and promoted by manufacturing industry (Toyota Production System). In line with this, in recent years the government plans to accelerate the construction of highways by giving concessions to investors who then lead to <br /> <br /> <br /> competition among investors, so investors are required to make some effort to develop the toll road industrial sector. In this case, this effort can be made by investors began to be directed to an effort to improve the performance of the toll road project to be as lean as possible. One of them is to improve supply chain performance of the toll road project or in other words make the supply chain become leaner. However, owners in an effort to improve supply chain performance of toll road projects are stuck with the fact that the implementation of <br /> <br /> <br /> toll road projects undertaken by contractors, including in creating and managing the project supply chain network that makes the owner can not directly control the project supply chain. So in this case, which can be done by a limited owner intervention activities of the supply chain project which is the contractor's supply chain of toll road project (Wirahadikusumah and Abduh, 2009), especially in controlling the projects supply chain network, namely the procurement activities and also on the implementation of activities which are both performed by the contractor. <br /> <br /> <br /> The forms of owners intervention to supply chain of this toll road project is divided into two models according Wiirahadikusumah and Abduh (2009), first is Nominated by Owner (NO) model and also Created by Owner (CO) model, which have different implementations each other according to owner characteristic. In this case the owner intervention of the supply chain project for CO models is <br /> <br /> <br /> greater than the owner intervention on the NO model. Given the differences in levels of intervention undertaken by the owner of the course will be very influential on efforts to increase the toll road project implementation performance, <br /> <br /> <br /> particularly in reducing waste that may occur and increase the value expected by the owner. Does the substantial of owner intervention can make the creation or implementation of supply chain networks become more lean construction or just the opposite. Therefore we need a study to examine the extent to which the effect of the owner intervention was associated with the implementation of lean concepts, in an effort to improve supply chain performance of toll road projects that lean, especially on the model of NO and CO, which can be known whether the increased levels of the owner intervention can support supply chain performance improvement efforts on the project procurement activities and also during construction performed by contractors or even discourage contracting activity. In this study, the owners intervention in the supply chain of toll road projects be reviewed towards the procurement and construction activities will be assessed against the concept of lean (lean thinking), using the perspective principles of lean production (conversion view, the flow view, and value view), so the specific owner interventions can be described as the procurement and execution of <br /> <br /> <br /> construction activities on each model of NO or CO is applied. Approach taken in this study is a qualitative approach with free guided interview method. The analysis technique will be used is the comparison technique. The comparison was made between a description of the application of lean concepts to owner intervention in the supply chain project (NO and CO models). That way, you will <br /> <br /> <br /> see whether the owner intervention is still adhered to the conventional system or had begun to be directed to the lean system, whereas previously conducted study of the effect of owner interventions assessed against the production perspective approach based on the lean concept (conversion view, the flow view, and value view), according with each classification. So in the end, this analysis process will <br /> <br /> <br /> lead to findings based on measurement results, namely in the form of intervention conducted less support, enough support, or very supportive of aspects of the production outlook based on lean principles. The results of this study indicate that greater levels of intervention owner does not <br /> <br /> <br /> necessarily have a positive influence in improving the performance of the highway project. In this case, owners need to limit their intervention activities provided so as not to inhibit the activities of contractors, and owners also need to mature enough planning in every interventions activity.
