This study aims to analyze the mental workload with the experimental method when operating a lathe under two different conditions, namely by using cooling and without cooling. The material used as the specimen in this research is AISI 4140 material. Another important variable is the timing of the experiment in the morning and evening. This is related to the division of work shifts that often occurs in the manufacturing industry. The working time factor greatly affects work performance and vigilance at work. Based on the experimental results taken from 20 participants and processed with the NASA-TLX method, it shows that the mental workload in the lathe process with the addition of cooling is more significant than the lathe process without the addition of cooling, even though the data collection time is different. It is also directly proportional to the duration of the lathe process. So it can be concluded that the turning process is better to use cooling even on AISI 4140 Steel material because it does not require a high workload.

This reseach aimed to measure the mental workload of data entry processing tasks in the e-commerce industry based on mental workload value. It was to determine the factors influencing mental workload mainly induced by the data entry process. The experiments without work instruction and with two types of work instruction were conducted to diagnose the mental workload. The measurement of the initial mental workload condition of data entry employees was conducted in the laboratory. Then, the Electroencephalogram (EEG) measurement using sensors from Emotiv was performed every 30 minutes, and the data of EEG measurements (focus, engagement, and stress) were collected using the laptop. Meanwhile, pulse measurement (heart rate) was measured before and after the work. Raw National Aeronautics and Space Administration Task Load Index (NASA-TLX) and reaction time measurement were conducted after the work. Through these experiments, the researchers identify that mental effort and fatigue are the significant determinants of mental workload value in the data entry process of the e-commerce industry. In respect of the results of work performance analysis, it is recommended that the placement of work instruction should be near the employee. Then, the task demand (minimum completion target) should be adjusted according to each employee’s capacity.

Nurse is a profession that has a quite high workload. It can be seen from how often they should encounter situations which compel them to undergo precisely right decision in saving patients’ lives. Various environmental conditions increase the frustration rate of the nurses, such as noise of the crowds and medical equipment, as well as smell of medicines and wounds at once. Moreover, demands from the patients’ family make it even tougher for them. Therefore, this study aims to measure the mental workload of the nurses at Intensive Care Unit (ICU) and emergency unit (IGD) in the Hospital ZA based on their years of service. The study was conducted using the method of NASA-TLX (National Aeronautics and Space Administration – Task Load Index). It measured the workload in six dimensions: Mental Demand (MD), Physical Demand (PD), Temporal Demand (TD), Own Performance (P), Effort (EF), and Frustration Rate (FR). The results of the study show that the average value of the nurses’ workload at ICU and IGD is in the category very high (respectively 80 and 83) for the nurses with 0-3 years of service, and the most contributing factor for both the primary groups is the effort (EF).

Abstract              Workers’ workload in the work place can cause the difference of work performance. One of the effect is job stress on the workers. Job stress can caused by workload factor in the work place, one of the workload is mental workload. The purpose of this research was to analyze job stress on workers in PT. Kerta Rajasa Raya. This research was an observational descriptive research, using cross sectional approach. The sample of this research was 47 morning shift-workers in Circulator Loom Unit PT. Kerta Rajasa Raya. The technique of collecting sample was total sampling method. The collected data was mental workload assessment that use NASA-TLX questionnaire, fulfillment of job stress measurement that use questionnaire which adopted from International Stress Management Association (ISMA). Data analysis was using Spearman Correlation test. The result of the research shown that most workers has mental workload with medium category (53,2%) and job stress with medium category (76,6%). Correlation coefficient (r) between mental workload and job stress is 0,186. This shows that there was a very weak correlation between mental workload and job stress on workers in PT. Kerta Rajasa Raya. Based on this data, it can be concluded that mental workload is not factor that caused job stress. It is suggested for the related company to do some efforts to reduce the level of job stress by holding a routine exercise and recreation to the workers. Beside that, it is suggested to make a job rotation to the workers.

Some previous research using a new augmented reality map display called Mirror-in-the-Sky (MitS) showed that performance was worse and mental workload (MWL) greater with MitS relative to a track-up map for navigation and wayfinding tasks. The purpose of the current study was to determine—for both MitS and track-up map—how much performance improves and MWL decreases with practice in a simple navigation task. We conducted a three-session experiment in which twenty participants completed a route following task in a virtual environment. Task completion times and collisions decreased, subjective MWL decreased, and secondary task performance improved with practice. The NASA-TLX Global ratings and Detection Response Task Hit Rates showed a larger decrease in MWL with MitS than the track-up map. Additionally, means for performance and workload measures showed that differences between the MitS and track-up map decreased in the first session. In later sessions the differences between the MitS and track-up map were negligible. As such, with practice performance and MWL may be comparable to a traditional track-up map.
