Research on job performance has been conducted in various contexts, such as in the education, agricultural, and banking sector. However, knowledge on this issue in other contexts, particularly the construction sector, is still limited. Therefore, this study was conducted in the context of state-owned construction companies, known collectively as BUMN Karya, to address this gap. BUMN Karya has a pivotal role in Indonesia’s economic growth. This study examined the effects of organizational factors (human resource management practices, transformational leadership) and individual factor (organizational citizenship behavior, work motivation) on job performance. This study also examined the effect of human resource management practices, transformational leadership, and organizational citizenship behavior on work motivation. In addition, this study examined the role of work motivation as a mediator between human resources management practices, transformational leadership, organizational citizenship behavior, and job performance. The research data were collected through survey from 776 employees of BUMN Karya. The data were analyzed with regression analysis to test the direct relationships between the variables. Hierarchical regression analysis was carried out to test the mediation hypotheses. The results showed the significant relationship between organizational citizenship behavior and work motivation and between organizational citizenship behavior and job performance. In addition, the current study revealed a significant relationship between work motivation and job performance. Finally, this study found work motivation as a mediator between organizational citizenship behaviour and job performance.

This study aimed to examine the factors that influence employee performance such as human capital practices, transformational leadership and organizational citizenship behaviour (OCB). This study uses a census approach, where all members of the population are made as respondents with a total of 233 employees in human capital department of state’s owned construction companies. Analysis approach in this research is descriptive statistical analysis and analysis of structural equation modelling (SEM). The results of this study found that there was a positive and significant impact of human capital practices on employee performance, transformational leadership on employee performance, and organizational citizenship behaviour (OCB) on employee performance. These results indicated that the better human capital practices, transformational leadership and organizational citizenship behaviour (OCB) of the company will increase and improve employee performance better. We do suggest for the future research to use the mediator such as work motivation between the factors that impact employee performance such as human capital practices, transformational leadership and organizational citizenship behaviour (OCB) and employee performance.
