Abstract
This study aims to determine how big the level of musculoskeletal complaints is, the fatigue and increase productivity of batik maker after body posture changes in coloring (dyeing) hand drawn batik cloth uses a machine in standing body posture. This study used Nordic Body Map musculoskeletal measurements and subjective fatigue, the research method used the experimental design of the same subject, namely the design that is variable observation carried out several times, the control subject also applied as the experimental subject. The results of processing data on 20 batik makers were concluded that the percentage of pain in the coloring activity (manual dyeing) by squatting and stooping body posture with a mean was about 65.18 ± 6.45%. The percentage of pain in the machine dyeing activity for standing posture was 50.73 ± 71.73%. The average difference between the level of musculoskeletal complaints on batik staining with squatting/stooping body posture compared to the staining of the standing body posture was 16.80 or a decrease of 19.34%. The results of subjective fatigue questionnaire obtained a decrease in fatigue of manual dyeing activity with dipping machines, namely an activity attenuation decrease from 90% to 62%, attenuation of motivation from 88% to 58%, physical attenuation from 78% to 64%. The average difference between the degree of fatigue in batik staining and stooping body posture compared to the staining of the body posture is 25, 25 or there is a decrease in fatigue of 26.69%. The work posture improvement of standing position on batik dyeing machine that is designed using 3 roll (cylinders) which has a driving power of 0.190 HP, with the working concept of a sheet of fabric wrapped around a cylinder with a 72.5 rpm rotation, frame material made of elbow iron painted and cylinders made of data a the PVC pipe to avoid corrosion could actually increase work productivity by 0, 0190 or 29.19%.
