Tujuan penelitian ini adalah untuk mengetahui risiko ergonomi pekerjaan tenun ulos yang dilakukan dan hubungannya dengan keluhan MSDs pada pekerjaan tenun ulos di Kelurahan Martimbang dan Kelurahan Kebun Sayur Kota Pematang Siantar. Penelitian ini merupakan penelitian observasional. Penelitian ini dilakukan pada 42 orang pekerja tenun ulos. Tingkat risiko ergonomi per bagian tubuh terkait postur, beban, durasi dan frekuensi menggunakan REBA serta tingkat keluhan MSDs per bagian tubuh yang dirasakan oleh pekerja menggunakan kuesioner Nordic Body Map. Hasil analisis risiko ergonomi dengan metode REBA terhadap tahapan pekerjaan tenun ulos memiliki tingkat risiko ergonomi paling tinggi pada tahap menarik kayu. Hasil kuesioner Nordic Body Map, paling banyak merasakan keluhan MSDs pada pinggang belakang (79%), bahu kanan (71%), bahu kiri (62%), pantat (62%), lengan atas kanan (50%) dan betis kanan (50%). Distribusi keluhan MSDs berdasarkan umur paling banyak pada pekerja umur 30 s/d 45 tahun, berdasarkan jenis kelamin paling banyak pada perempuan, berdasarkan masa kerja paling banyak pada pekerja dengan masa kerja lebih dari 10 tahun dan berdasarkan kebiasaan olah raga paling banyak pada pekerja yang tidak terbiasa berolah raga.
The pupose of this study was to determine the risk of weaver ulos who carried out the work ergonomics and its relationship with symptons of MSDs in Martimbang and Kebusn Sayur Village Pematang Siantar City. This was an observational study. The population amounting to 42 people. The level of ergonomics risk related to the body posture, weight, duration and frequency using REBA tool, and the level of MSDs complaints that is felt by workers per part of the body using Nordic Body Map questionnaire. Ergonomics risk analysis results using the method of REBA according to the stages of weaving ulos that pull timber is the highest one. Nordic Body Map Questionnaire results about MSDs complaints were many who complained on the waist (79%), right shoulder (71%), left shoulder (62%), bottom (62%), right upper arm (50%) and right calf (50%). Distribution of MSDs based on age mostly occur on workers aged 30 until 45 years, based on sex mostly occur on female workers, based on working experience mostly occur on workers which has been worked for more than 10 years and based on sport habit mostly occur on workers whish have no habit of working out sports.
Complaints of musculoskeletal disorders (MSDs) in general can occur due to contraction or excessive loading of muscles or bones. One example of an activity that can trigger the incidence of musculoskeletal disorders (MSDs) is manual material handling work. Manual material handling work is still commonly found in the work done at CV Bengkel Otomotif. This study focuses on looking at the relationship between physical and individual variables with complaints of musculoskeletal disorders (MSDs) in CV Bengkel Otomotif workers. This research is a cross-sectional study with quick exposure check and nordic body map instruments. Of the 60 workers who became respondents to the study, it was found that 38 workers (63.3%) had complaints. The part of the body that experienced the most complaints was the waist (25 workers). The results showed that there was a relationship between the variable body mass index (p value = 0.004), and exercise habits (p value = 0.004) with complaints of musculoskeletal disorders (MSDs).
Working process in section Bagging Off has the risk of MSDs to workers. Thisstudy describe the risk level of ergonomic which potentially causingmusculoskeletal disorders to workers and an overview of complaint subjectivemusculoskeletal disorders on workers at PT. JAPFA Comfeed Indonesia UnitTangerang. The design of this study is cross sectional using REBA and RULA toassess the ergonomic risk level at each stage of working process and Nordic BodyMap (NBM) to know where the complaints on workers. Based on REBAassessment on working process of palleting showed very high risk level, RULAassessment on working process of sewing showed very high risk level and REBAassessment on working process of bagging showed high risk level and mediumrisk level. NBM assessment showed there is 20 workers have complaint in waist,8 workers have complain in under waist and 7 workers have complaint in upperneck and right shoulder. This level of risk can be reduced by providing AdjustablePallet Stand to working process of palleting, redesign workplace on workingprocess of sewing and providing chair which is suitable to workers on workingprocess of bagging. Besides that, workers have to stretch the muscles beforeworking, in the middle of working and after working, and then working with thecorrect posture.
