Abstract: The process of making Batik Cap in Batik ‘Supriyarso’ exposed to workers complaints of musculoskeletal disorders (MSDs), particularly on neck, shoulder, back, arms, wrists and hips. The present study evaluates the ergonomic risks at the hand activity level by using The Postural Loading on The Upper Body Assessment (LUBA) method and The American Conference of Governmental Industrial Hygienists-Hand Activity Level (ACGIH HAL) method. The object of research is five workers with a range of 48-64 years of age who work in the cap printing process. Determination of work activities using the LUBA method there are 14 activities and the ACGIH HAL method is available 13 activities. The results of data processing are done using Shapiro-Wilk Test, Spearman Test, Mann Whitney Test within Statistical Product and Service Solutions (SPSS) Version 21.0. The ergonomic evaluation using LUBA method obtained a mean risk value of 3, showing the risk is need for immediate corrective action. Meanwhile, the ACGIH HAL method obtained a mean risk value of 1, showing the risk is acceptable and no corrective actions are needed. Based on the ACGIH HAL method, repetitive motions are influenced by work speed and work fatigue, exposing the risk of MSDs. The worker’s right hand has higher risk compared to the left hand. In conclusion, the results shows that recommendation, working methods should be revised and supporting tool can be utilized to reduce muscle fatigue caused by repetitive motions.
