Perancangan stasiun kerja instruktur laboratorium desain produk dan inovasi menggunakan metode ergonomic function deployment

The Product Design and Innovation Laboratory (Desprin), Faculty of Technology, Institute of Technology is a necessary facility in an effort to support the implementation of an educational process that implements a competency-based curriculum. This study aims to produce an ergonomic instructor workstation design in the laboratory by applying the Ergonomic Function Deployment (EFD), 12 ergonomic principles, and anthropometric data with the 5-95th percentile with selecting concepts from several concepts that have been designed. The final result of this research is a workstation design in the form of a drawing table, computer desk, and instructor chair designed using Solidworks 2018 software. The drawing table can be folded when not in use and attached to a computer table so that user movement is more effective and the selected chair is able to work synergistically with the two tables.

Emergency Physicians’ Workstation Design: An Observational Study of Interruptions and Perception of Collaboration During Shift-End Handoffs

Background: Frequent external interruptions and lack of collaboration among team members are known to be common barriers in end-of-shift handoffs between physicians in the emergency department. In spite of being the primary location for this crucial and cognitively demanding task, workstations are not designed to limit barriers and support handoffs. Objective: The purpose of this study is to examine handoff characteristics, actual and perceived interruptions, and perceived collaboration among emergency physicians performing end-of-shift handoffs in physician workstations with varying levels of enclosures—(a) open-plan workstation, (b) enclosed workstation, and (c) semi-open workstation. Method: Handoff and interruption characteristics were captured through in-person observations of 60 handoffs using an iPad-based tool. Additionally, physicians participating in the handoffs responded to a survey pertaining to their perception of interruptions and collaboration with clinicians during each phase. Other organizational and demographic data were obtained from the hospital database, surveys, and observations. Results: Physicians working in the open workstation experienced a significantly higher number of interruptions/hour (18.08 int/hr) as compared to the semi-open (13.62 int/hr) and enclosed workstations (11.41 int/hr). Most physicians perceived that they were interrupted in the semi-open and open workstations. In addition, majority of physicians in the enclosed pod perceived high collaboration with clinicians involved in and present in the workstation during handoff. Conclusion: This correlational study showed positive outcomes experienced by physician working in the enclosed workstation as compared to the open and semi-open workstations.

Models for Estimating the Hearing Threshold of Quarry Workers at High Frequencies

It is widely known that quarry industry has great importance in developing countries, such as Nigeria. There is paucity of information regarding effects of noise experienced by quarry workers during their working time. Therefore, this study investigated the influence of age of workers, years of exposure of workers and noise level of the machine used in quarry on hearing threshold. A factorial design of experiment was employed for the investigation. Two hundred and four quarry workers volunteered for this study from four quarries in South western Nigeria. Emitted noise, which quarry workers were exposed to during machinery operation, was measured with a digital sound level meter and workers hearing threshold was measured in an audiogram sound proofing testing booth at standard conditions. Predicted models were established from experimental design to determine main and interactions effects towards the response (hearing threshold). These were statistically analysed using analysis of variance (ANOVA). All terms of the models were significant at p<0.05. The best fitted model was at 4kHz (R2 = 0.639, p<0.05). The magnitudes of the main effect of the factors are in ascending order of noise level >years of exposure>age. The analysis of the experimental response indicated that there is no interaction of any factors on the hearing threshold. It can be concluded that age, years of exposure and noise level have main effects at various capacities at different frequency to predict the hearing threshold of the quarry workers. This work determined the factors and the predicted model to spell out safe hearing threshold of quarry workers that fitted for the job at a particular noisy workstation as well as ensuring comfortable, safe and effective workstation design.

Personality and Workstation Type Predict Task Focus and Happiness in the Workplace

Employee personality traits have long been studied in the context of workplace outcomes, and drawbacks of certain workstation types have become regularly debated in the last decade. However, very little is known at the intersection of these two areas of interest. This study of 231 federal office workers explored how personality levels interacted with workstation type (open bench seating, cubicle, private office) on-task focus and happiness. Momentary assessment and global, one-time survey methods were used to capture a more ecologically valid understanding of such interactions. While global ratings of task focus were higher for those in private offices than those in cubicles and open bench seating, there were no differences between workstation types in momentary assessments of focus. Several personality trait-workstation type interactions were found, including support for the idea that certain affordances of open bench seating are more beneficial to momentary focus and happiness for employees high in extraversion, while detrimental to momentary focus for those high on neuroticism. Taken together, these findings suggest that a consideration of individual differences is critical to advance the workstation design conversation in order to best support the most valuable asset of an organization: the employee. Concern for the employee is especially important in the current context of the global pandemic that is driving a rapid evolution in approaches to both short and long-term strategies for workplace design and policy.
