Fatigue during driving is the main contributing factor to road accidents. It is influenced by time on task (TOT) and time of day (TOD). Recent electroencephalogram (EEG) research on fatigue assessment has shown a promising result in explaining the fatigue phenomenon. However, different findings exist regarding the best EEG parameters related to fatigue. This study examined EEG changes according to the effect of TOT and TOD and determined the best parameters to distinguish fatigue status. To generate driver fatigue, prolonged driving in the morning and at night in a simulator was conducted. The EEG signal was collected from 28 male participants at frontal and occipital areas. The EEG power (brainwave) was determined from the first and last 5 minutes of the driving task and after a break of 30 minutes. The results of this study showed a general tendency of EEG power changing throughout the driving sessions. However, changes related to fatigue were only found for the night sessions, as confirmed by q power and the subjective fatigue measurement result. This study showed that TOT (as a factor that induces fatigue) was explained by q from the frontal area, whereas TOD was differentiated by a, q, q/b, (q+a)/b and (q+a)/(b+a).

Employees’ workload can be high when the existing manpower is limited and the list of jobs to do are long. For the employee, the workload may affect their job satisfaction and their performance in the long-term. Assessment of workload and its influence to job satisfaction was done at Sustainability and Operation Department of cultivates and harvests oil palms Company in Indonesia. The workload was measured using NASA-TLX that measure mental demand, physical demand, temporal demand, performance, effort, and frustration. While job satisfaction is measured using a questionnaire about superiors’ support, colleagues assistance, remuneration, and promotion. The assessment result showed that employee’s workload in these departments was identified as rather high. This is coming from commonly overtime exists and high domestic traveling frequency. Besides that, there is a correlation between workload and job satisfaction. There is two correlations model, positive and negative. The high workload can improve the job satisfaction, but otherwise, it can decrease job satisfaction. To reduce the workload, information system and database suggested for the company to reduce the employee difficulty in accessing data to finish their job that caused excessive overtime.

Studies on the driver's fatigue, must focus on at least two things: the time-of-day that affect by circadian factors, and time-on-task. This paper discusses the risk level of driver fatigue, which generally have to drive in a long duration or more than 4 hours. The risk of fatigue was assessed using Fatigue Likelihood Scoring (FLS) by Transport Canada. Based on interviews with 24 inter-city bus drivers, 18 of the 24 drivers have a very high risk of fatigue that characterized by FLS scores greater than 20, while the rest have a high risk driver that characterized by FLS value greater than 10. A high risk of chronic fatigue that experienced by most of drivers caused by working hours which is more than 36 hours in a week, the duration of the shift of greater than 8 hours a day, lack of time off, the amount hours of driving at night, and the amount of time off.

Fatigue is a common situation experienced by everyone, but until now a simple measuring tools universally accepted is not exist. Fatigue measurement instrument most widely used is an instrument-based questionnaire. This study used the Swedish Occupational Fatigue Index (SOFI) as one of the instrument to measure BRT driver’s fatigue. The aim is to evaluate physical mental, and shift work fatigue and provide an overview of fatigue levels experienced by the driver BRT on two different shifts. Hopefully it can be used for driver fatigue management by a company. The study was conducted for two different shifts (morning and afternoon), with a total participants are 30 drivers. Results showed that motivation level of shift 2-driver is lower after they finish their work compared to shift1-driver. In shift 1, generally available time to rest,socializing and hanging out with family is longer than available time for shift 2-driver. Perception of loss of energy after work is also higher in shift 2 compared to shift 1, especially the perception of feeling exhausted. Similar results were obtained in the physical aspect and the physical exertion and physical discomfort. Therefore we can conclude the work shift has affected fatigue level experienced by the driver's BRT, and shift rotation is suggested to help the driver to recuperate.

Subjective fatigue measurement instruments, based questionnaire, is a measure that is widely used for reasons of practicality and measurement results can be obtained quickly. For the purposes of measuring fatigue, there are a number of questionnaires commonly used abroad, but not a lot of literature with a case study in Indonesia that utilize this instrument. Of course, the reason for the use of the instrument is based on the expectation that the instrument has high validity and reliability, and if possible to have a high level of practicality as well. Asssment Fatigue Scale (FAS) is one of the suggested use as a measurement of worker fatigue. The instrument consists of a 10 item questionnaire with good reliability level. The discussion in this paper covers Measurement Scale Fatigue testing results via questionnaires measuring fatigue, adapted from the FAS in English and translated into Indonesian. DSS consists of 10 questions using 5 Likert scale, for the answer options are: never (1), sometimes (2), perceived a regular basis (3), is common (4), is always experienced (5). Relaibilitas test results using Cronbach alpha values obtained value of 0812, and can be improved if the item is question number 3 is removed. By implication, this questionnaire is good enough to use as a measuring instrument fatigue, but the level of proficiency in Indonesian language, in this CMS, needs to be repaired, especially for question number 5 and 3 if the level of validity and reliability to be improved, although the increase may not be too significant.

This research identified any kind of work condition and craftsman’s posture that trigger the pain and discomfort for craftsman of doormat in Pringapus, Semarang. Observation of the work condition is conducted including work facilities and their posture during sewing process. To identify their pain and discomfort, Nordic Musculoskeletal Questionnaire (NMQ) is used as reference. The result is used as an input for rapid upper limb assessment worksheet (RULA) to determine the level of the risk. RULA’s final score is indicated the conditions need further investigation and change may be needed. Based on the analysis using fishbone diagram, to overcome pain/discomfort in the area of the neck and the shoulder, high adjustment of table and seat is suggested, because the evidence shows they trigger the craftsmen’s bad posture. For pain/discomfort of back and waist, the seat should have good back support. Whereas for the hip, the craftsman suggested to use the seat with thick and wider sleeper, so they can sit comfortably. For foot problems, to relieve the pain for their free feet, it is suggested to use a bench that functions as foot rest; and for the sewing feet, it is suggested to give heels support so the sewers' heels can be free from strain while sewing.

2.64% is the largest defect percentage of aerosol can product of PT Multi Makmur Indah Industri. To improve the product quality, the study focused on the goal of reducing the percentage of defects using the Statistical Quality Control. After gaining control of the company, we can calculate the process capability in the aerosol can manufacture. The next step is identification of the defects causes that arise using the failure mode and effect analysis (FMEA) method to measure the defect causes risks and as an input in determining control recommendations. From the observations and data processing, it is recognized that the overall phase of the process has a process capability value above 99%. 80% of defects in the aerosol cans product occur during the process of can making, component making and printing. While the most risking defect cause is the destruction ofmachine B coating on the printing process (RPN = 245) and the quality of the welding wire on can manufacturing process (RPN = 160). Therefore, the solution to reduce the defect percentage is replacing the damaged coating machine B as well as upgrading the quality of the welding wire. Thus, it can reduce the losssale as much as 1.06% (Rp110,716,000) per month.
