The Work Posture Evaluation at Assembly Work Station in MSEs of Silver Jewelry Handicraft with the REBA Method

The objective of this work was to evaluate farming machines adapted to forestry work and to verify if their characteristics meet the safety, ergonomics and working conditions necessary to maintain the health and safety of the operators. Thus, three farming tractors were selected, with a closed cabin and a minimum power of 73.5 kW, a widely used specification in the forestry sector. The following ergonomic parameters were considered: acess to the cab, cab dimensions, visibility, seat, controls and operation, work posture, cabin air conditioning, noise, lighting and maintenance aspects. The evaluations were based on the guidelines contained in the “Ergonomic Guidelines for Forest Machines” of the Swedish Forestry Research Institute, developed for forestry machines. The results showed that all the evaluated machines presented ergonomic standards below those indicated in all evaluated aspects, particularly related to access to the work station and difficulties during mechanical maintenance, besides the necessity of adopting forced postures during the working day due to operator’s seats. It was concluded that the farming machines adapted for work in forest processes presented significant gaps in relation to the ergonomic aspects, which represents high and imminent risks of development of occupational diseases in their operators, as well as the predisposition to work accidents.

Pekerjaan manual masih banyak ditemui pada berbagai aktivitas kerja. Pekerjaan manual yang dikerjakan secara berulang (repetitive) dengan gerakan kerja monoton dan waktu kerja yang lama berpotensi menimbulkan kelelahan kerja. Pada gerak monoton repetitive terjadi pembebanan otot yang terus menerus. Postur kerja yang salah membuat kelelahan menjadi lebih cepat terjadi. Postur kerja yang tidak baik ini seringkali diakibatkan oleh desain fasilitas kerja yang kurang memperhatikan kesesuaian dengan penggunanya. Pada pekerja laundry aktivitas menyetrika pakaian merupakan kerja repetitive monoton yang kurang didukung fasilitas yang sesuai. Postur kerja dengan berdiri dan terjadi twist serta seringkali membungkuk. Operator setrika harus melakukan kegiatan setrika selama lebih dari 8 jam. Penelitian bertujuan melakukan redesain pada stasiun kerja setrika agar diperoleh postur kerja yang baik. Perancangan stasiun kerja menggunakan software Jack 8.2. Stasiun kerja yang terdiri dari meja dan kursi dirancang dengan memperhatikan antropometri dan kebutuhan gerak operator. Evaluasi desain dilakukan dengan mengevaluasi postur kerja dengan menggunakan analisis biomekanik, menggunakan analisis toolkit yang meliputi analisisi SSP, LBA, RULA, dan OWAS. Dari hasil evaluasi, dihasilkan postur usulan yang diberikan adalah, pekerja duduk pada kursi dengan posisi tubuh tegap, arah kepala sejajar dengan arah objek yang dikenai pekerjaan, dan pekerja dihindarkan dari posisi kerja membungkuk dan twist. Abstract(The Design of Working Station and Working Posture Using Biomechanic Analysis to Reduce Static Load and Musculoskeletal Disorder).The work that is done manually is usually done repeatedly with monotonous movements and long working hours. If the muscle’s working too hard, the muscle will be found damage and fatigue. The right working posture can improve the worker’s ability to finish the job. Wrong posture is often caused by the facility design that unsuitable to operator. In the laundry workers ironing clothes activity is monotonous and repetitive work which is lacking in appropriate facilities. Work posture by standing up, often bent and twist. Ironing operator do their activities for more than 8 hours. The research aims to redesign the work station in order to obtain a good working posture.

Musculoskeletal disorders (MSDs) are diseases in the human muscular tissue system in the back, wrist, knees and shoulders caused by incorrect postur during work activities. This study was conducted to determine the level of risk MSDs on operator work activities at the cast house work station. Activities under study are activities; surface repair tap hole, checking temperature iron, and take iron sample. These activities are carried out repeatedly, incorrect work posture and the presence of heat from work environment factors that affect the whole body. This makes the operator complain of pain in parts of the body at risk of developing musculoskeletal complaints. This study was an observational study using the Rapid Entire Body Assessment method and the Nordic Body Map instrumen. The result of the Nordic Body Map instrumen for 20 operators at the cast house work station showed that there were 21 complaints against operator. Based on the measurement of cast house operators the surface repair activity of tap holes has a “high” risk value for MSDs (REBA Score 9), checking temperature iron activities have a “low” risk value for MSDs. Proposed improvement to prevent is to improve the procedur in the surface repair activities of tap holes, where when the process of sticking the dough is done in front of the tap hole is changed by attaching it to the mud gun nozzle tip. After the proposed improvement, the result of the Nordic Body Map instrumen showed no complaints and the measurement of the tap hole had a “low” risk value for the occurrence of MSDs (REBA Score 3).
