Di dalam perusahaan produksi rokok ini terdapat sebuah mesin laser perforator. Setelah pemasangan mesin laser perforator 50 timbul masalah yang berhubungan dengan gangguan muskuloskeletal. Saat dilakukan wawancara, operator mengeluhkan adanya nyeri punggung bawah  karena penanganan material dilakukan secara manual. Setelah dilakukan analisis dengan metode OWAS pada dua kegiatan bongkar muat ditemukan masalah yang berhubungan dengan gangguan muskuloskeletal. Dari hasil analisis ditemukan bahwa aktivitas pemuatan (loading) dikategorikan sebagai tindakan korektif 3 artinya postur tubuh berpengaruh sangat merugikan pada sistem muskuloskeletal, sedangkan kegiatan pembongkaran (unloading) termasuk tindakan korektif 2 yang tidak berpengaruh nyata terhadap sistem muskuloskeletal. Selain itu, analisis gaya tekan dilakukan hanya untuk aktivitas pembebanan terhadap gaya tekan total yang bekerja pada L5/ S1. Gaya tekan untuk aktivitas pembebanan adalah 7.186,22 Newton atau lebih dari dua kali lipat dari batas aman maksimum 3.400 Newton. Perbaikan dilakukan dengan menggunakan metode QFD. Sebagai solusinya adalah dibuat troli. Troli tersebut mampu mereduksi gaya tekan total pada aktivitas pembebanan menjadi 3.180,52 Newton dan berhasil mengubah menjadi kategori tindakan korektif 1. Abstract[REDUCTION OF MUSCULOSCELETAL DISORDERS RISK ON LASER PERFORATOR MACHINES AREA IN CIGARETTE COMPANIES USING QFD AND OWAS] Inside this cigarette production company, there is a laser perforator machine. After the installation of the laser perforator machine 50, problems related to musculoskeletal disorders arise. During the interview, the operator complained about low back pain due to manual handling of the material. After analyzing the OWAS method on two loading and unloading activities, problems were found related to musculoskeletal disorders. It was found that the loading activity was categorized as 3 meaning that posture had a very detrimental effect on the musculoskeletal system. Meanwhile, unloading activities included category 2 which had no significant effect on the musculoskeletal system. In addition, the biomechanical analysis was carried out only for the loading activity against the total compressive force acting on L5 / S1. The compressive force for loading activity is 7,186.22 Newton or more than twice the maximum safe limit of 3,400 Newton. Repairs were made using the QFD method. The solution is to make the moving trolley. The moving trolley is able to reduce the total compressive force on the loading activity to 3,180.52 Newton and also, reduce the level to category 1.Keywords: biomechanics; musculoskeletal disorders; Ovako Working Posture Analysis System; OWAS; Quality Function Deployment; QFD; Trolley

Sweet Whey Powder

In this 4.0 industrial era, some material handlings are still conducted manually by human. One example is in the warehouse area of CV Cita Nasional, a milk processing factory in Kopeng, Central Java. Workers are repetitively unloading a 25 kg sack of sweet whey powder from truck to warehouse area. Therefore, this study was carried out to investigate the musculoskeletal disorders risks on that workers manual handling activity. The OVAKO Working Posture Analysis System (OWAS) was chosen to be applied in the evaluation steps. For each activity in the unloading process, OWAS score category of 3 (improvements are necessary as soon as possible) were resulted on lifting, 2 (improvements are necessary in the long-term future) on carrying, and 3 on lowering the load. Consequently, a trolley was then designed to minimize the risks. The trolley was designed based on Indonesian anthropometry dimensions. Applying this proposed tool, lifting and lowering activities were then categorized in OWAS score of 2, whilst carrying was resulted in OWAS score of 1 (improvements are not necessary). This applied study was valuable in order to minimize the musculoskeletal disorders risks on such manual material handling activity, not only in the current workplace, but also in similar situation of industries.

A preliminary survey showed that oyster mushroom farmers in Lempake Samarinda experienced pain in several body segments, especially at their waist. It may be attributable to the working condition that requires non-ergonomic postures such as frequent awkward posture in sitting or standing position. Therefore, this paper aims to assess the working posture in oyster mushroom farmers. Ovako Working Posture Analysis System (OWAS) method was applied to measure the risk level of farmers' working posture. A total of ten activities were observed from the oyster mushroom cultivations' process in four cultivations in Lempake, Samarinda, Indonesia. Each activity was assessed using the OWAS category based on the position of the back, arms, legs, and load. The result showed that 10% of farmers' working posture was classified in the 4th risk level category, categorized as highly dangerous for the musculoskeletal system, so direct improvement was needed. Furthermore, 10% of working postures were classified in the 3rd risk level category, and 60% of working posture was in the 2nd risk level category, which is categorized as dangerous for the musculoskeletal system and could cause significant tension so that improvement in the future as needed. On the other hand, 20% of working posture was classified in the 1st category which was safe for the musculoskeletal system

Abstract: Modern design of dental equipment does not totally prevent the profession from experiencing low back pain (LBP). This study was aimed to determine the prevalence of LBP, to analyze risk factors associated with LBP, and to analyze risk factor for LBP among dentists in North Sulawesi. This was a quantitative and analytical study with a cross sectional design. Samples were determined by using the purposive sampling method, namely 148 dentists who met the inclusion criteria. Data were collected by using the Ovako Working Posture Analysis System (OWAS) questionnaire to assess the posture of the dentists during treatment by adding individual and occupational characteristics. Further data were analyzed univariately, bivariately, and multivariately by using the SPSS program. The results showed that the prevalence of dentists who experienced LBP was 41,2%. In addition, work position (p=0.043, correlation coefficient Ф=0.166), and the number of patients in a day (p=0.025, r=0.190) had a significant correlation with NPB. In conclusion, work position is the most influential factor of LBP among dentists in North Sulawesi (OR=2.085, CI=95%). It is expected that all dentists should avoid working positions that could harm their musculoskeletal systems.Keywords: low back pain, dentist  Abstrak: Perubahan desain peralatan kedokteran gigi yang semakin mutakhir tidak menjadikan profesi dokter gigi terbebas dari keluhan nyeri punggung bawah (NPB).

This study aimed to systematically compare three representative observational methods for assessing musculoskeletal loadings and their association with musculoskeletal disorders (MSDs): Ovako Working Posture Analysis System (OWAS), Rapid Upper Limb Assessment (RULA), and Rapid Entire Body Assessment (REBA). The comparison was based on a literature review without time limitations and was conducted on various factors related to observational methods. The comparisons showed that although it has a significant limitation of comprising only two classifications for the leg postures, (1) the RULA is the most frequently used method among the three techniques; (2) many studies adopted the RULA even in evaluation of unstable lower limb postures; (3) the RULA assessed postural loads as higher risk levels in most studies reviewed in this research; (4) the intra- and inter-reliabilities for the RULA were not low; and (5) the risk levels assessed by the RULA were more significantly associated with postural load criteria such as discomfort, MHTs and % capable at the trunk, and MSDs.
