Abstract

Job Safety Analysis (JSA) is a method to identify and evaluate work steps and potential hazards to determine appropriate control measures. The ultimate goal of this research is to identify the potential for work accidents, assess the potential for work accidents, and provide risk control for existing work accidents. The results of this study found a variety of common hazards such as physical injury (puncture, scratch, pinch, fall), chemical hazards (dust inhalation, skin irritation), and mechanical hazards (slipping, falling material). In the concrete field, accident risks include being buried in soil, tripping over stones, slipping, inhaling dust, and being injured by work tools. While in the electrical field, the risks include being scratched by tools, falling from a height, being punctured by nails, and respiratory problems. The assessment of work accidents at PT Tunas Jaya in 2022 mostly shows a high risk of work accidents and repeatedly occurs. In addition, the factors affecting work accidents were analysed using the Job Safety Analysis (JSA) method. recommendations can be given to control the risk of work accidents in the next construction project at PT Tunas Jaya by updating the existing Standard Operating Procedures (SOP), adjusted to current field conditions.

Abstract

A scientific paper is a writing that follows scientific principles and research ethics, supported by reference citations. Mendeley facilitates reference management; however, many students are not yet accustomed to using it. This study aims to evaluate the use of Mendeley and identify areas for improvement. The research method employed usability testing with the System Usability Scale (SUS) instrument. Statistical testing was also conducted, involving 24 students from the Industrial Engineering Program at Udayana University. Participants completed five task scenarios related to Mendeley features. Data on system effectiveness and efficiency were collected during the trials. The results show that Mendeley achieved an SUS score of 72.1, indicating an acceptable usability level with a Grade C and a “good” adjective rating. System effectiveness reached 100%, with all participants completing all tasks. Efficiency evaluation showed a rate of 0.177 goals/second, meaning users could complete 0.177 tasks per second. Statistical analysis indicated no significant differences in SUS scores or system efficiency based on gender. Furthermore, there was no correlation between SUS scores and system efficiency. These findings suggest that usability ratings are not directly related to system efficiency.
