Professional Construction Workforce Commitment Model in Maintaining Project Performance in East Kalimantan

The impact of labor quality on project effectiveness is crucial, influenced by factors like leadership style, motivation, and work-life balance. Companies must consider the commitment model of professional construction workers to enhance project performance, especially in resource-scarce regions like East Kalimantan. Researchers aimed to identify this commitment model's role in East Kalimantan's projects. Using a mixed method with 250 respondents, including various stakeholders, the study found that authentic leadership positively affects worker commitment and project outcomes (accepted hypotheses H1, H2, H5, H7), while other hypotheses were rejected (H3, H4, H6). Data were collected via questionnaires and interviews, analyzed using SEM SmartPLS for quantitative data and qualitative methods for interview data.
