CV Madyotomo is a printing company in Karanganyar,Central Java, that produces student worksheet books (LKS)through a series of manual and semi-mechanical productionprocesses. Production employees are routinely exposed torepetitive manual handling, such as lifting paper rolls,feeding printing machines, and stacking finished books,which increases the risk of work-related musculoskeletaldisorders whenworking postures are not properlymanaged.This study aims to assess the ergonomic risk level ofproduction employees at CV Madyotomo using the QuickExposure Check (QEC) method, which evaluates exposurebased on back, shoulder/arm, wrist/hand, and neck posturecombined with movement frequency, workload, and workduration. All 19 production employees across fiveworkstations were involved as respondents through a totalsampling technique, using paired observer and workerquestionnaires. The results show that no workstation fallsinto the safe category, with average exposure levelsrangingfrom 46.96% to 88.63%. The Goss and Stitching/Mullerworkstations recorded the highest exposure levels andrequire immediate corrective action, mainly due to manualpaper-roll handling and repetitive lifting during the bindingprocess. Ergonomic improvementrecommendationsincludethe provision of lifting aids, adjustment of work table andconveyor height, and administrative controls such as jobrotation and stretching programs to reduce exposure levelsand prevent musculoskeletal disorders among productionemployees.
