Abstract

Fatigue is a feeling of weariness or lack of energy that does not decrease when a person rests. The main reason of occupational accidents caused by humans is stress and fatigue. This study aims to analyze the differences of reaction time and fatigue stage between morning shift workers and night shift workers of coal mining department operators in PT. Kaltim Prima Coal. This research was an analytic observational research with cross sectional approach and purposive sampling technique. Data taken from 30 workers of morning shift and 30 workers of night shift who fulfill the inclusion criteria. The results showed that the average reaction time of morning shift workers was 0.81 seconds and 0.89 seconds for night shift workers. The results of questionnaire showed amount of very tired worker category, tired, and less tired on the morning shift workers for each category were 7, 21, and 2, while the night shift workers for each category were 3, 25, and 2. Results of unpaired t-test for reaction time showed no significant difference (p = 0.2) and the results of the Kolmogorov-Smirnov test for fatigue stage showed no significant difference (p = 0.952) between the morning shift workers and night shift workers of mining coal department operators in PT. Kaltim Prima Coal. Keywords: Reaction time, fatigue stage, shift workers

Abstract

Orthostatic hypotension is a common problem in the elderly. High incidence of orthostatic hypotension in elderly associated with decreased baroreceptor sensitivity and declining elasticity and muscle strength inferior. This study aims to determine the differences in reaction time in the elderly with and without orthostatic hypotension in Panti Sosial Tresna Werdha “Budi Sejahtera” Banjarbaru and Martapura. This study was an observational study with cross sectional analytical and decision-purposive sampling technique. Data will be tested for normality prior to the Kolmogorov-Smirnov test for normality. Data analysis using unpaired t test. The results of the study the average reaction time of 30 elderly people with orthostatic hypotension is 2.069 seconds and 30 elderly people without orthostatic hypotension is 1.775 seconds. The results of the Kolmogorov-Smirnov normality test p =0.919 indicates the data are normally. The results of the analysis of the unpaired t test p =0.022 (p <0.05) indicate that there are significant differences. The results that the reaction time in the elderly with orthostatic hypotension longer than without orthostatic hypotension in Panti Sosial Tresna Werdha “Budi Sejahtera” Banjarbaru and Martapura. Keywords: orthostatic hypotension, the elderly, reaction time
