Abstract

The development of the era where everything is instantaneous and fast as it is today must be supported by the development of increasingly sophisticated information technology. One of the functions of this technological development is to obtain accurate and fast information. But in fact, there are still companies / organizations that have not used computer technology as a work aid, such as the Bromo Rajawali Convection which still uses the manual method of writing employee data, namely data storage still using books. Therefore, the design of an employee data management information system is carried out that can help companies control the production data of each tailor employee. The method used in this research is the Waterfall method. It is called a waterfall because the steps that are passed must wait for the completion of the previous stage and run sequentially, for example the design stage must wait for the completion of the previous stage, namely the requirements stage [1]. The Waterfall method consists of 5 stages, namely Analysis, Design, Coding, Testing and Maintenance. The purpose of this study is to design an information system that can make it easier for companies to write down employee production data accurately. From the design results, there are two factors that support the running of the system, namely administration and production data, the input form available on the system that has been designed, namely the login input form and the employee data input form, while the output form contains complete data related to employee personal data and employee production data. With the creation of a management information system in writing data on employee production, the Rajawali Bromo Convection can accelerate the search for more accurate data in the future, and applications made later by the company can be used properly as one of the employee production data systems

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

Appropriate Technology (AT) is widely applied in the agricultural sector to improve post-harvest productivity, including the use of corn shellers. However, many existing corn shellers have not fully considered usability and ergonomic aspects, which may lead to inefficiency, errors, and increased cognitive and physical workload for users. This study aims to evaluate the usability of a corn sheller and identify physiological parameters that indicate usability levels. An experimental method was employed involving two groups of participants, namely novice users and experienced users. Usability evaluation was conducted using the System Usability Scale (SUS), user performance indicators (task completion rate, task completion time, and error rate), and physiological measurements in the form of body temperature changes before and after task execution. The results showed that experienced users achieved a higher average SUS score (88.50, excellent usability) compared to novice users (58.50, marginal usability). Experienced users completed tasks faster, achieved a 100% task completion rate, and made fewer errors. Novice users required longer completion times, showed higher error rates, and experienced greater increases in body temperature. The findings indicate that usability is strongly influenced by user experience and cognitive factors. Body temperature changes can be used as an objective physiological indicator of usability and workload. Improvements in system learnability and user guidance are recommended to enhance usability for novice users.
