Introduction: Worker performance is influenced by individual characteristics, workload and work climate, with work stress often being a factor that reduces performance.
Methods: This cross-sectional study of 148 production workers at PT Maruki International Indonesia (May–July 2025) examined the effects of age, gender, physical and mental workload, and work climate on performance, with work stress as a mediator. Data collected using performance questionnaires, NASA-TLX, heat stress monitors, pulse oximeters, and salivary α-amylase tests were analyzed through SPSS (univariate–bivariate) and AMOS path analysis to assess direct and mediating effects.
Results: The results at the 95 % confidence level or CI =0.05 show that age has a significant effect (p=0.320>0.05), but a significant positive effect on performance (p=0.000 <0.05). Gender has a significant effect on job stress (p=0.038 <0.05) and performance (p=0.004 >0.05). Physical workload has no significant effect on work stress (p=0.810>0.05) and performance (p=0.330>0.05). Mental workload has a significant effect on work stress (p=0.000 <0.05) but not significant on performance (p=0.258 >0.05). Work climate has no significant effect on work stress (p=0.636>0.05) and performance (p=0.613>0.05). Job stress itself has a significant positive effect on performance (p=0.000 <0.05). Job stress mediates the relationship of age to performance (indirect effect=0.027), physical workload to performance (indirect effect=0.009), and work climate to performance (indirect effect=-0.018).
Conclusions: worker performance is directly influenced by age, gender and job stress and indirectly by age, physical workload and work climate through job stress.
