Construction services are activities to create buildings that function as support or infrastructure for socio-economic activities for national development. In its implementation, there was a construction failure, which resulted in the project being late and experiencing additional costs. In the period July 2017 – August 2020 there were more than 34 incidents of construction failure that occurred in Indonesia. Of these various incidents, the cause is mostly due to human factors, one of which is the leadership factor. Therefore, research is needed regarding what factors influence the leadership system to reduce the failure rate of construction. The purpose of this study is to find leadership system variables and indicators that affect the failure rate of construction in national private construction implementing service companies. The analysis was carried out on 148 respondents who work in the national private construction services sector. The research method used is quantitative methods with a research instrument in the form of a questionnaire and analyzed with the help of SmartPLS. Of the 11 leadership variables from the literature study and expert input, it was found that only the stakeholder involvement variable with 7 indicators had a direct effect on construction failure.

Construction failure is still a major issue in the construction world, especially in Indonesia. There were so many construction failures in Indonesia hence the Indonesian government suspended all infrastructure projects and gave sanctions to the companies. This research was conducted at several state-owned construction companies in Indonesia. There were 7 main variables to be examined in this research, i.e. National Culture, Professional Culture, Policy, Organization Culture, Quality Management System, Quality Culture, and Construction Failure. The quality culture variables are divided into 3 i.e. Leadership, Communication, and Maturity. This research was designed through 3 stages i.e. archive analysis, respondent survey, and expert validation. The respondent survey was conducted by distributing a closed questionnaire to 150 respondents. Structural Equation Modeling (SEM) was used to analyze the relationship of the variables. Then the results were validated by experts in the field of construction quality management with more than 25 years of work experience. The analysis shows that National Culture, Policy, and Quality Management System variables significantly influence quality culture namely the Leadership system but Professional Culture and Organization Culture variables don't influence quality culture namely the Leadership system. Quality Culture variable is represented by Leadership significantly influence to Failure Construction. This research can serve as a basis for the development of a quality culture strategy to reduce construction failures. [ABSTRACT FROM AUTHOR]
