Cleaning workersare jobs that require physical strength especially if the work is carried out at a height, and it is not uncommon to complain about musculoskeletal discomfort in physical areas that feel uncomfortable when working in an un ergonomic position. From the observation results If observed posture when cleaning wokers work, body position tilted and bent with angles ranging from 20°-60°, neck bent with an angle of about 20 °, cleaning is done repeatedly by shifting the left hand and right hand with the angle of the upper arm > 90° raised for 10 minutes and forearm around 40°, this illustrates the condition of awkward posture cleaning wokers not ergonomic, posture that is not ergonomic will cause musculoskeletal disorder.The purpose of this researchis to measure the effect of stretching on mental workload in an effort to mental recovery. To achieve these objectives, first determine the type of glass cleaning activity outside the building at a height including: preparing tools, climbing stairs, cleaning glass, moving to other areas and cleaning tools, determining stretching movements, then conducting experiments in this case divided into 3 (three) treatment, first without stretching, giving stretching in the morning at 10 am for 6 minutes and stretching during the day at 2 pm for 6 minutes. Measurement of mental workload using the Subjective Workload Assessment Technique (SWAT) method, statistical processing by carrying out the covariance homogeneity test, Multivariate test and followed by the MANOVA test. The results of this researchthat stretching in addition to having a positive influence on the decline in mental workload, can also be used for mental recovery. Working at a height with a work posture that is not ergonomic, will increase the level of mental workload.
