To overcome these problems then the sitting work attitude is changed based on the anthropometry of workers that refers to the principle of ergonomics. The study was conducted in March 2017. The design of this study used the treatment by subject design involving 10 samples. Intermediate intervals before treatment and after treatment were given washing out for two days. The study was conducted in home industry located at West Teuku Umar Street. The measured data were the workload seen from the work pulse, enhancement in musculoskeletal complaints recorded with Nordic Body Map questionnaire and work productivity.
