This study aims to identify the highest dimensions, levels, and relationship between mental workload and work stress among sewing department employees across three activities, namely thumb sewing (A), hand body sewing (B), and velcro and logo sewing (C) at PT XYZ, using a quantitative method with NASA-TLX and HSE-WRSS instruments involving 20 respondents per activity. Results showed that Temporal Demand was consistently the highest mental workload dimension across all activities with average scores of 77.5, 71.5, and 70.5. The Control dimension recorded the highest work stress in Activities A (4.58) and B (4.61), while the Role dimension was highest in Activity C (4.33). Mental workload levels in Activities A and B were classified as high with scores of 63.47 and 61.18, while Activity C was moderate with 59.40. Work stress across all activities was classified as moderate with scores of 139.15, 132.40, and 137.80. A significant and positive relationship between mental workload and work stress was confirmed through simple linear regression in Activity A (Sig. 0.023; R²=0.254) and Spearman Rho correlation in Activities B (r=0.734) and C (r=0.741), both categorized as strong.670 Teknik Industri2026-05-26UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS SAINS DAN TEKNOLOGIThesis
