Abstract
CV Valasindo is furniture industry that produces a wide range of wood product.The production process in CV. Valasindo is devided in two areas, preparation of materials area and production area. This research is focused on work posture of the production area’s workers. The production area itself consists of work stations such as assembly, construction and finishing. The production area was chosen because on the production process in this area is still done manually by the operator. Additionally, on the production area is also still present a series of no ergonomic work posture, both on the work station construction, assembly and finishing. The purpose of this research is to identify a work posture on the production area and doing an improvement to lowers the risk of musculoskeletal injuries. Based on the results of the assessment work posture against 18 work stations at the production area, the seat assembly work station it is known that has the highest risk of musculoskeletal injuries with a score of REBA 9, OWAS 3 as well as score NBM 75. Based on work by posture assessment method of QEC, REBA, OWAS and reinforced with method NBM then the improvement will be focused on work station assembly seat. In this study, the improvements done by designing a working facility in the form of tables and chairs work. Based on the results of the design work facilities have been simulated and the result is the risk of musculoskeletal injuries that used to be high risk decrease to be low
Highlights
CV Valasindo is furniture industry that produces a wide range of wood product
This study focuses on the work postures performed by workers in the production process
The work stations that have the highest risk score based on the assessment by Rapid Entire Body Assessment (REBA) method, Ovako Work Postur Analysis System (OWAS) and reinforced with Nordic Body Map (NBM) methods that work station assembly seat so the focus of repairs will be done at the work station
Summary
Musculoskeletal disorder system are a complaint on the parts of the skeletal muscle felt by a person, ranging from very mild to sick complaints (Tarwaka, 2011). JITI, Vol 17 (2), Des 2018,117 - 124 manually by the operator In addition to this process there is a series of work postures that are not ergonomic either at work stations construction, assembly, and finishing. While at the work station assembly process is done with the posture of the body sitting on a chair, squatting on the floor and bending to take part to be assembled Awkward work posture such as working with excessive standing, squatting, bending, and vibration from machines and equipment used can lead to musculoskeletal complaints that can impact on declining work performance (Nugraha et al, 2013). Based on the existing problems the results of this study is expected to be used as a reference in improving the work posture of the operator especially in the production area to minimize the risk of musculoskeletal injuries
