Abstract
This study was conducted at the Intelligence and Security Directorate (Intelkam) of the Riau Regional Police (Polda Riau), located in Pekanbaru City, Riau Province, involving a population of 128 personnel. The sample was determined using the simple random sampling technique. Based on the Krejcie and Morgan (1970) formula, the sample size was adjusted to meet the requirements of the analysis. Data were analyzed using the Structural Equation Modeling (SEM) approach based on Partial Least Squares (PLS). The hypothesis testing results indicated that the High Performance Work System (HPWS) had a positive and significant effect on thriving at work (β = 0.309; p = 0.008) and psychological capital (β = 0.468; p < 0.001). Furthermore, psychological capital had a positive and significant effect on thriving at work (β = 0.508; p < 0.001). In addition, psychological capital was found to significantly mediate the relationship between HPWS and thriving at work (β = 0.237; p < 0.001). Overall, the findings indicate that the implementation of HPWS not only exerts a direct effect on enhancing thriving at work but also indirectly promotes thriving at work through the strengthening of psychological capital as the underlying psychological mechanism among personnel of the Intelligence and Security Directorate of the Riau Regional Police..
