Abstract

The implementation of material procurement supply chain management is very much needed by the construction industry to improve project performance. Supply chains can contribute to reduced costs, improve efficiency and improve the delivery of a material's final results promptly on time. So that it is expected to achieve the project objectives in accordance with the cost, quality and time. that had been planned. This research aims to determine the influence of the implementation of supply chain management of material procurement to the performance of construction projects and the biggest challenges in implementing supply chain management of material procurement. The analysis methods used in this study are descriptive methods and regression methods with quantitative approaches. Data collection techniques using a questionnaire and using a Likert scale. The number of respondents as many as 28 people selected from project employees with purposive sampling method. The results showed that the application of material procurement supply chain management characteristics had a positive and significant effect on the performance of construction projects by 39%. As well as the biggest factors that become challenges in implementing supply chain management of material procurement, namely the uncertainty of demand with an average of 2,797 and the smallest factor that becomes a challenge in implementing supply chain management of material procurement, namely internal uncertainty factor with an average of 2,202. Thus, from the results of the research, it is expected that the project can play a more active role in implementing supply chain management of material procurement to improve the performance of construction projects.

Abstract

A problem that often occurs in construction projects is the delay in the implementation process. Various factors cause the delay, but in developing countries such as Indonesia, the dominant delay occurs because the implementing contractor causes it for unforgivable reasons (non-excusable delay). This study aims to determine the influence of the non-excusable delay parameter and the relationship between these factors. The research is quantitative with data collection techniques in the form of unstructured interviews, field observations, and surveys using research questionnaires with the number of respondents obtained as many as 33 people consisting of the owner, construction management consultant, quantity surveyor consultant, and ends with confirmation of the results. Research on the implementing contractor. Data analysis was performed using multiple linear regression analysis. The test results of multiple linear regression analysis show that the non-excusable delay factor can significantly affect the completion of construction projects. The influence of each element is 0.434 units for the lack of contractor competence, 0.067 units for inappropriate implementation planning, and -0.097 for inefficient field management units. And simultaneously, these three factors can significantly increase the project delay value index.
