Abstract

Purpose: This study aimed to measure the mental workload experienced by employees in the finance department and to analyze the effect of mental workload on employee performance. Design/methodology/approach: This study used the Subjective Workload Assessment Technique (SWAT) method to measure the mental workload faced by employees who must perform various activities in their work. Findings: The results of this study indicate that the time load factor (T) is the dominant factor affecting employee workload because employees are required in terms of time to perform each activity included in the work process quickly, precisely, and in large quantities every day. Mental workload has a direct and significant positive effect on employee performance. Research limitations/implications: Data collection was only conducted on employees of the Finance Department of PT Bumi Jasa Utama. Practical implications: Based on the results of this study, the company is expected to increase the number of employees in the finance department to streamline time and minimize the workload of each employee in the finance department. The company is also expected to improve service and service quality by considering employee comfort and performance. Originality/value: The condition of employees who are given a high workload and ongoing causes stress and anxiety, so it is necessary to measure mental workload and the effect of mental workload on employee performance.

Abstract

This study analyzes emission loads generated from plastic waste shredding activities around the Antang Landfill. The process involves the use of transportation vehicles, diesel engines, polypropylene sacks, and polyethylene terephthalate (PET) packaging from used cooking oil containers. Diesel combustion and transportation activities contribute to air pollution, while shredded plastic waste may release additional emissions into the environment. The research aims to evaluate the environmental impacts of plastic waste shredding and propose strategies for sustainable waste management. The Life Cycle Assessment (LCA) method was applied to assess environmental aspects and potential impacts through input–output inventory analysis. Data were processed using SimaPro software, with impact assessment conducted through categorization and normalization stages. The findings reveal three main impact categories: global warming, ozone layer depletion, and human toxicity. The collection stage contributes most to human toxicity (4.66E-5 and 2.48E-16), while the transportation stage produces the highest emissions from operational vehicles (8.12E-5 and 4.32E-16). During the shredding stage, diesel combustion contributes most to ozone layer depletion (1.02E-8) and human toxicity (2.52E-13). The plastic fragment handling stage shows significant impacts on ozone layer depletion (7.9E-9) and global warming (8.69E-13). Further research is recommended to develop emission reduction strategies that integrate cost efficiency and stakeholder participation.
