AN ANALYSIS OF QUALITY IMPROVEMENT THROUGH IMPLEMENTATION OF ISO 9001:2015 IN PROJECTS CONSTRUCTION

The construction requires good quality management in order to deliver project results that meet customer needs and meet the requirements already planned. The implementations of such ISO 9001:2015 will contribute to improve the quality of product which produced by the company. This study aims to determine the significance effect on the variable measure from the ISO 9001:2015 clausal on project construction management. The survey was conducted in four construction projects. The independent variables used in this study consisted of seven indicators, which are organization management (X4), Leadership (X5), Planning (X6), Support (X7), Operation (X8), Performance evaluation (X9), and Improvement (X10). The dependent variable is the quality of the project outcome (Y). The quality improvement correlation and the significance will tested by using multiple regression linear. The results from the analysis are the overall Mean Score, the quality score is 3.843, which is the highest score from the questionnaire spread among 35 respondent. Furthermore, the F test obtained 12,419, higher than shown in F table 2,39, which shown that the implementation of ISO 9001: 2015 simultaneously affected to the quality improvement on the construction project. The conclusion from the analysis was shown on the formulation: Y = -0.503 + 0.470X4 - 0.061X5 + 0.075X6 - 0.190X7 + 0.388X8 + 0.597X9 - 0.130X10. There are three clauses that affected to the quality significantly, ie: performance evaluation with score 0.597, organizational context 0.470, and operational 0.388. Meanwhile for the leadership, planning, support, and improvement, statistically have not affected significantly, as the p-value obtained is higher than 0.05. Furthermore, its need to ensure that all indicators should be well organized by the contractor in progress to reach quality improvement, review operational control, and evaluate progress, method, and final check for all projects, simultaneously.
