This cross-sectional research study aims to determine the factors that cause musculoskeletal disorders, especially focusing on crane operator workers at PT Terminal Petikemas Belawan. The sample for this research is 63 crane operators who have at least 2 segments of complaints experienced by workers with the results of the SNI 9011-2021 assessment level of medium and high risk. Data on complaints of musculoskeletal disorders were collected using the GOTR-AK complaint survey questionnaire by SNI 9011: 2021, assessment of work posture using SNI 9011: 2021 Measuring and evaluating the potential for ergonomic abuse in work templates, exercise (whole body vibration) using the Humlan vibration meter, physical activity using a questionnaire PAL (physical activity level), and fatigue using a reaction timer measurement tool. Then, the data were analyzed using the SPSS version 29 application with the Spearman test to see correlations and multiple regression to see the effect of work and individual factors as a cause of musculoskeletal disorders in crane operators. The results showed a strong correlation between work posture and complaints of musculoskeletal disorders (p <0.01), correlation of individual age factors with complaints of musculoskeletal disorders (p <0.01), physical activity (p <0.01), fatigue (p <0 .01) and smoking behavior (p < 0.01). The results of multiple linear regression tests show that work posture is 7 times more dominant in affecting musculoskeletal disorders complaints in crane operators and age has a 3 times greater risk of experiencing musculoskeletal disorders complaints or every year the age of crane operators increases as a factor causing musculoskeletal disorders in crane operators at PT Terminal Petikemas Belawan
