Abstract

One of the risks in the workplace today is the risk of ergonomic hazards, apart from the risks of hazards that often occur such as risks of physical hazards and risks of hazards from the work environment. If the risk of physical hazards and the risk of environmental hazards already have many safety signs that are widely accepted, this is not the case with the risk of ergonomic hazards that do not yet have a validated and widely used safety sign. More fundamentally, awareness of the risks of ergonomic hazards is not fully understood by both workers and employer institutions. The method used in reviewing this paper is to enter the keywords safety sign, safety sign design, and ergonomic risk factors on google scholar and science direct.

Abstract

Concentration is essential in order to help to perceive and understand the object that is being focused. If students can concentrate, everything can be recorded properly in the brain's memory. If student concentration experiences obstacles in learning activities, there will be obstacles to achieve goals. This study aims to analyze the influence and relationship between concentration levels when listening to different audio stimuli. The methods that can be used quantitatively to see learning concentration are reaction time and memory recall methods for 30 students. The data obtained are processed using statistical tests, that is the T test and ANOVA test to test the differences in sample means from different variables and draw conclusions by finding different data groups. Based on the results of the T test, giving the three audio stimuli to men did not provide a significant average difference in reaction speed. Meanwhile, for female respondents, only the favorite song stimulus had a significant average difference. There is no significant difference in memory recall ability to audio stimulus. For the male respondents, the instrumental stimulus was the most effective stimulus, while for the female, the favorite song stimulus was the most effective.
