Abstract

Background, The prospect of oil palm plantations is currently rising significantly to become a favourite business. However, the work activities of TBS loading-unloading workers are still performed without paying attention to ergonomic aspects and have the potential for MSDs. Aim: To map the potential MSDs of TBS loading-unloading workers, serving as a basis for improving the work system. Methods: The inclusion sample of TBS loading-unloading workers was observed and interviewed using the NBM questionnaire to diagnose potential MSDs resulting from MMH work activities. Ergo-MMH was applied to provide recommendations for improving work system design based on the AT and SHIP approaches. Results: The primary causes of MSDs are unnatural working attitudes and excessive muscle tension resulting from work systems that are not designed per the limitations of workers. Twelve body parts are directly involved in MMH activities. Conclusions, Possible MSDs on the back, left and right shoulders, right and left upper arms, right forearm, left and right wrists, left and right hands, and upper and lower neck. Implication, Ergo-MMH-based mapping of potential MSDs in manual material handling activities of TBS loading-unloading workers for the academic world; research, theory development, and education. For society, public awareness, community development, and social support. For the nation and state, work safety, economic growth, and public health. For the international community, international collaboration, standards development, and technology development

Abstract

Background: Computers are the main devices that support the efficiency and effectiveness of work in modern office environments, including MSMEs in South Sumatra Province. However, long-term use of computers with unergonomic sitting postures can increase the risk of Work-Related Musculoskeletal Disorders (WMSDs) in workers. The results of preliminary observations showed that the percentage of variation in WMSD complaints was between 13%-42% of the total work-related diseases related to computers. Aim: This study aims to identify muscle complaints experienced by workers, analyze the risk of working posture using ergonomic methods, and provide suggestions for improvements to minimize the risk of musculoskeletal disorders. Methods: This study uses the Rapid Office Strain Assessment (ROSA) method to assess the risk of computerized and sitting activity-based work postures. In addition, Nordic Body Map was used to map the location of muscle complaints in respondents. The study was conducted on 20 workers in four MSMEs in South Sumatra Province who worked with high computer intensity. Results: The analysis showed that all four respondents had a high level of occupational posture risk based on the ROSA score. A total of 36 muscle complaints were reported, with the most complaints located in the lower neck, waist, and buttocks. The main factors causing complaints include prolonged static sitting positions and inadequate adjustment of work facilities. Conclusions: The work posture of MSME workers in South Sumatra Province indicates a level of ergonomic risks that requires serious attention. Interventions such as improving work facilities and training in correct work posture are highly recommended. Implementation. These findings affirm the importance of applying ergonomic principles in computer-based work environments to prevent WMSDs, improve work comfort, and support the productivity of government sector workers.

Abstract

The increasing demand for ergonomic and flexible wheelchairs in Indonesia highlights the need for innovation that meets both user needs and national standards. Most wheelchairs circulating in the domestic market are low-cost imported products that do not comply with the ISO 7176 series SNI 09-4663-1998 medical device standard, leading to concerns over safety and quality assurance. This study aims to design an ergo-flexibility wheelchair prototype based on stakeholder technical requirements while identifying gaps in the existing standards to improve product competitiveness and user protection. The research integrates the Zachman Framework according to the FACTS stages with the Nigel Cross seven-step design method. Data were collected through observation, in-depth interviews, and participatory ergonomics focus group discussions. The data analysis employed the Inter-Rater Reliability (IRR) method to determine stakeholder agreement levels. The findings identified seven key technical parameters, stability, maneuverability, mobility, dimensions, strength, durability, and product information, that are essential for wheelchair standardization. The mapping analysis revealed that the current SNI standard primarily emphasizes product strength through drop testing, while other ergonomic and safety factors remain unaddressed. From the evaluation of three design alternatives, Alternative 2 was selected, featuring aluminum material, dimensions of 1000 mm (L), 620 mm (W), and 910 mm (H), a foldable transport design, semi-manual manufacturing, and a weight of 12 kg with an 80 kg load capacity. Prototype testing using a roll machine and static load confirmed its structural reliability and ergonomic performance. The research contributes to advancing national wheelchair standards by integrating stakeholder-driven design parameters, promoting local innovation, and enhancing the competitiveness of Indonesian medical devices.

Abstract

The increasingly intense competition, the number of customer choice options and the more selective customers in choosing medical equipment products require PT SPU as one of the Indonesian National Medical Device (Alkes) industry engaged in the production process of medical devices and rehabilitation to always improve a better work system. To improve product quality PT SPU has implemented the SNI ISO 9001: 2008 Quality Management System which contains standard requirements used to measure the organisation's ability to meet customer requirements and appropriate regulations. The purpose of this research is to identify and assess how much influence each component of the work system has on the satisfaction of customers, employees and leaders. The method used is Macro Ergonomics. The magnitude of the contribution of the work assessment process of SNI ISO 9001: 2008 implementation to the influence of significant macro ergonomic aspects on organisational conditions (52.45%), physical environment (37.37%), production processes (12.53%), infrastructure (9.69%), production process services (5.90%), and R&D activities (2.82%).(3) Proposed recommendations for improving organisational conditions by confirming the roles and responsibilities of each person so that there are no undisciplined employees between sections, improving communication. Physical work environment by rearranging the place and rejuvenating production process support tools that are not ergonomic and have been damaged, redesigning a conducive and comfortable work environment. Production process improvements including employees actively communicating with each other and development of standard operating procedures (SOPs) with legacy competencies through knowledge transfer. Improvements to Facilities and Infrastructure by adding air conditioning, such as blower/exhaust ventilators, and sufficient room ventilation. Improvements to R&D: by facilitating employee exchanges for R&D activities, training, technical guidance, and experience exchange; increasing access to cooperation with government and private organisations.

Abstract

Manual wheelchairs remain widely used in Indonesian health-care facilities, yet their design often does not fully accommodate local anthropometric characteristics and work patterns. The SM-8018 patient wheelchair used at PT SPU is operated by caregivers, exposing both patients and caregivers to potential ergonomic risks. This study aims to evaluate and redesign the SM-8018 wheelchair using an integrated Ergo-Total Function Deployment (ETFD) and House of Ergonomics (HoE) approach within a Total Ergonomics framework. A pre–post experimental design was applied involving 32 adult users and caregivers with at least six months of experience using or pushing the SM-8018. Data collection included anthropometric measurements, musculoskeletal complaints using the Nordic Body Map (NBM), subjective fatigue using the Japan Association of Industrial Health (JAIH) questionnaire, boredom scores, satisfaction using the Minnesota Satisfaction Questionnaire (MSQ) and voice of customers (VoC). VoC and ergonomic findings were mapped into a HoE matrix to derive priority design specifications through ETFD. Results showed notable mismatches between user anthropometry and key wheelchair dimensions, particularly seat depth and width, backrest and headrest height and angle, and push-handle height, which were associated with high levels of discomfort in the lower back, buttocks, shoulders and upper arms and with considerable fatigue. The ETFD–HoE analysis identified four primary redesign priorities: adjustment of push-handle height, optimisation of backrest and headrest geometry, refinement of seat dimensions and improvement of front-wheel stability. Pre–post comparisons indicated that musculoskeletal complaints and fatigue remained relatively high and in some cases increased, whereas boredom and satisfaction tended to change in a more favourable direction. These findings suggest that the first iteration of the SM-8018 redesign, although guided by Total Ergonomics principles, requires further refinement and system-level support. Nonetheless, the study demonstrates the feasibility of integrating ETFD, HoE and Total Ergonomics to systematically guide the improvement of low-cost hospital wheelchairs in the Indonesian context.
