Abstract

The COVID-19 pandemic impacted almost all countries and caused disruptions in education. Governments, including Indonesia, closed schools and campuses to mitigate the spread of COVID-19, leading to a transition to online learning. This lasted for two years and continued with hybrid learning. The abrupt change increased stress, especially for already stressed students. This study assessed stress levels during online learning at the Industrial Engineering Study Programme of Maranatha Christian University, Bandung. Stress was measured subjectively using the Perceived Stress Scale (PSS) and objectively using Galvanic Skin Response (GSR) and pulse sensors on thirty-two students. The PSS results classified the stress perception of most students as ‘normal’ or ‘moderate’. Meanwhile, the results of the GSR and pulse sensor measurements indicated that the students were stressed. Furthermore, a comparison of stress levels between synchronous and asynchronous learning and between mathematics and theory courses was conducted. According to the findings, there was a difference in the average heart rate values between synchronous and asynchronous learning. There was also a difference between mathematics and theory courses. With this research, it is necessary to pay attention to learning methods, materials, etc. need to be designed to reduce student stress and improve student performance.

Abstract

Optimal laundry room design is essential for efficiency and comfort in washing, drying and ironing clothes. This research identifies people's need for a functional and comfortable laundry room, along with increasingly busy lifestyles. Non-ergonomic designs can reduce efficiency and comfort. Therefore, this research aims to provide a design solution that suits the preferences of users in Indonesia. A total of  123 respondents participated in the survey, of which 100 met the inclusion criteria through purposive sampling. The design thinking and jobs-to-be-done approaches were applied to explore an in-depth understanding of user needs. The results show that all respondents (100%) agreed that the proposed laundry room design is comfortable, functional, and ergonomically suitable, particularly in the height arrangement of the washing machine, accessibility of the drying area, and ironing layout. Dry room integration was also identified as a significant need. Based on the analysis, the recommended minimum size for an ergonomic laundry room is 220 cm x 300 cm, which supports efficient workflow and user comfort. This study emphasizes the importance of a user centered and ergonomic approach in residential space design to enhance daily comfort and productivity.
