Abstrak
The characteristics of the traditional small drum carvers are done by sitting on the floor, work with a bent position for 8 hours and 6 days a week. This is what triggers the incidence of sore muscle that is felt especially in the lower back. Interventions by mattress and Mc Kenzie exercise can reduce erector spinae muscle tension and musculoskeletal complaints due to work processes. This study aims to prove that sitting on the floor with matress and Mc Kenzie exercise can decrease muscle tension, musculoskeletal complaints and increase productivity among the traditional small drum carvers in UD. Budi Luhur Gianyar. This study was a true experimental, with a treatment by subject design. The Period 1 subjects were treated by conventional working conditions. Period 2 subjects were treated by sitting with matress and Mc Kenzie exercise. Washing out period and adaptation has given between two stages. Tension of the erector spinae muscle was measured by Surface Electromyography (SEMG) instrument, musculoskeletal complaints was measured by Nordic Body Map and productivity based on input and time with output formula. Effect of intervention was analyzed by Wilcoxon test and T-paired test. The results of this study was decrease in erector spinae muscle tension by 21.39% (p<0.05), decreased musculoskeletal complaints by 29.52% (p<0.05) and productivity increase by 22.13% (p<0.05). It can be concluded that the application of matress and Mc Kenzie exercise can decrease muscle tension and musculoskeletal complaints and increase productivity among the traditional small drum carvers in UD. Budi Luhur Gianyar. So it suggested to apply it to the carvers of the industry drum to minimize muscle, tension musculoskeletal complaints due to the work of carving.
