Abstract

The problem that occurs in the cleaning service staff at PT KAI is that besides cleaning the station area, they also have to do other work, such as cleaning trains, filling water in train toilets which should have its own officers. There are still many train passengers who dispose of their waste improperly, thereby increasing the workload of cleaning service officers. Another problem is the lack of division of tasks in each element of work. The number of officers in each shift is also not the same, a minimum of 2 and a maximum of 8 people. The number of officers on the morning and evening shifts is 6 to 8 people, while the night shift is 2 to 3 people. The cleaning service staff works for 8 hours per shift with no break time, resulting in complaints of fatigue of the cleaning service staff. This study aims to analyze the physical and mental workload on the cleaning service staff at PT. KAI Daop VI Yogyakarta using work sampling and NASA-TLX methods. Based on the results of this study it was known that the physical workload of staff on the morning shift was 88.6% (=7.1 hours) and on shift 1 it was 93% (=7.4 hours) for 8 productive working hours. The mental workload of staff on shift 1 was 73.3% and 75.0% on shift 2. This indicated that the cleaning service staff workload was classified as heavy and there was a need to improve the work system. This condition indicates that the cleaning service staff workload is heavy and needs to improve the work system.

Abstract

Many schools and campuses in Indonesia are built without considering the predetermined room temperature standards, so they are far from comfortable. Based on SNI 03-6572-2001, the optimal comfort category in Indonesia is 22.8°C-25.8°C. This study aims to determine the effect of temperature and humidity in the classroom on student fatigue and performance. The research was conducted using observation methods, questionnaires, and literature studies. The research was conducted at the UST Integrated Laboratory with 30 students as respondents living in the Special Region of Yogyakarta. The sample of students working on academic potential test questions by setting a specific temperature level, then filling out a subjective fatigue questionnaire. Data processing is done by correlation analysis and regression analysis. The results showed that the variables of temperature and humidity had a negative correlation with the fatigue variable with a deficient category and simultaneously had no significant effect. In comparison, the temperature and humidity variables do not correlate to the performance variables and simultaneously have no significant effect.

Abstract

Work fatigue is a state of the body that has decreased performance. One of the causes of work fatigue is the condition of a noisy work environment. The high noise factor can cause work fatigue which affects the decrease in the level of concentration when doing work. The research objective was to determine the effect of noise intensity on work fatigue and student performance. The experiment was carried out on 30 students as respondents who were in the Industrial Engineering Laboratory of the Universitas Sarjanawiyata Tamansiswa. Students are asked to work on Academic Potential Test questions in 3 different noise intensity variables which are divided into 3 sessions. The first session had a noise intensity of 63.3 dB, the second session 84.4 dB and the third session 91.6 dB. The data obtained were analyzed by Simple Linear Regression and Correlation Test. The results of the study stated that the variable effect of noise on work fatigue obtained a significance value of 0.021. The significance value of 0.021 is less than 0.05 which means that there is a significant effect of noise on student work fatigue. Then in the variable effect of noise on student performance, a significance value of 0.012 is obtained. The significance value of 0.012 is less than 0.05 which means that there is a significant effect of noise on student performance. For the correlation test, the Pearson correlation values were 0.999 and -1.000, which means that the strength of the relationship between the two variables has a perfect correlation.
