“…Most musculoskeletal disorders begin with discomfort and stress experienced by workers. The Nordic Musculoskeletal Questionnaire and Cornell Musculoskeletal Discomfort Questionnaire are examples of tools based on this method [45,46]. The advantage of this method is that no technical equipment is needed, making it relatively inexpensive and easy, with the data and input directly from the subject [47].…”

Work-related musculoskeletal disorders (WMSDs) are among the most common disorders in any work sector and industry. Ergonomic risk assessment can reduce the risk of WMSDs. Motion capture that can provide accurate and real-time quantitative data has been widely used as a tool for ergonomic risk assessment. However, most ergonomic risk assessments that use motion capture still depend on the traditional ergonomic risk assessment method, focusing on qualitative data. Therefore, this article aims to provide a view on the ergonomic risk assessment and apply current motion capture technology to understand classical mechanics of physics that include velocity, acceleration, force, and momentum in ergonomic risk assessment. This review suggests that using motion capture technologies with kinetic and kinematic variables, such as velocity, acceleration, and force, can help avoid inconsistency and develop more reliable results in ergonomic risk assessment. Most studies related to the physical measurement conducted with motion capture prefer to use non-optical motion capture because it is a low-cost system and simple experimental setup. However, the present review reveals that optical motion capture can provide more accurate data.

“…Manual and repetitive work in hot environmental conditions is one of the factors that has the potential to increase physical workload and the occurrence of work accidents so that it can cause occupational diseases (musculoskeletal complaints and fatigue) [7], [16], [17]. The temperature conditions of the hot work environment are often referred to as heat stress on workers.…”

The production process of making gamelan in Tihingan Village still uses the traditional way, namely using prapen with an open flame both for the melting process and in the formation process. This causes the workload of craftsmen to be quite heavy due to exposure to radiant heat and dust. The results of microclimate measurement of the work environment obtained an average dry temperature of 33.2oC, an average wet temperature of 24oC. The average ball temperature was 33oC, WBGT 26.3oC and the mean humidity (RH) was 59.0%. The average light intensity at work reaches 319.2 lux. The average temperature of the furnace at low heat is 340oC and during the combustion process it reaches 860 oC. The results of measurements of air quality in the workplace include levels of NO2 17.00 µg /m3 (increased by 112.50%), SO2 5.33 µg/m3 (increased by 45.23%), CO 407.16 µg/m3 (increased by 217, 99%), oxidants (Ox) 61.00 µg/m3 (increased by 1.67%) and dust 48.50 µg/m3 (increased by 125.58%). The mean pulse of the nguwad workers reached 125.81±1.35 beats/minutes (including heavy workload). This causes the productivity of craftsmen to be low due to the increase in musculoskeletal disorders and craftsmen fatigue. To overcome this condition, the workings of the craftsmen need to be improved immediately through the application of appropriate technology in the form of furnace repair so that the flames and dust produced can be removed from the workplace, then exposure to hot air and combustion dust will no longer expose the craftsmen.

“…Salah satu jenis pekerjaan yang terjadi adalah masih terdapatnya kegiatan pemindahan material menggunakan tenaga manusia, walaupun terdapat beberapa kegiatan yang menggunakan mesin sebagai alat bantu. Aktivitas pemindahan bahan secara manual (Manual Material Handling/MMH) mempunyai kelebihan karena kegiatan ini dapat dilakukan pada ruang terbatas, kelemahan pada aktivitas ini adalah sangat mengandalkan kekuatan fisik pekerja untuk mengangkat barang, MMH apabila tidak dilakukan secara ergonomis akan menimbulkan kecelakaan kerja dalam industri, yang disebut "Over Exertion-Lifting and Carying" [1] yaitu kerusakan jaringan tubuh yang disebabkan oleh beban angkat yang berlebihan. Banyak nya aktivitas produksi yang dilakukan secara manual dapat menyebabkan keluhan muskuloskeletal yaitu gangguan kronis pada otot, tendon, dan saraf yang disebabkan oleh pengguna tenaga secara berulang (repetitive), gerakan secara cepat, beban yang tinggi, tekanan, dan postur tubuh yang janggal [2] Penelitian ini dilakukan pada 4 departemen yang masih melakukan MMH.…”

PT. Cresco Indonesia is one of the companies that concerned in the Japanese slipper sandals industry in West Java, which was established in 1989. In order to responses to demanding costumer, PT. Cresco Indonesia applies â€˜make to orderâ€™ strategy, so the production process will be carried out if there are any orders from consumers. The company has 13 departments. Based on observations has known that there are 4 departments that have a potential to cause an accidents work, they are the happo department, the shiage department, the quality control department and the packing department. The beginning measurements of RULA and REBA out of four departments show the results of high risk action levels. To improve the situation, work system improvements must be made. This study intends to improve the body's posture and work system currently, so that the design of tools for the movement of baskets in the shiage and quality control departments, grouping and labeling in baskets in the happo department as well as improve the order of the process of lifting goods in the packing department. Work system improvement is carried out using biomechanics theory. The final result of the design shows the value of RULA and REBA of operators is low risk, minimizes the value of defects in the happo department, reduces the activities of finding baskets in the happo department, minimizes the time of movement from the shiage department to the quality control department, improves the way of lifting goods in the packing department and fix up the posture of the operators
