Abstract

World economic growth is directly proportional to the increase in the building sector. The building sectoraccounts for 31% of global energy consumption. Humans also increasingly recognize the importance of thehealth aspects, convenience indoor quality, and user safety in the building. This study combines theconcepts of green building assessment and green ergonomics to produce a new framework called greenergonomic building. The green ergonomic building is a building condition that not only focuses on energyuse, indoor quality but also health, convenience, safety, and improving quality of human life in carryingout their activities in buildings. The development of a green ergonomics building assessment model wasdeveloped from literature studies and questionnaires distributed to respondents working in green buildingcertified office buildings. Data processing using the Principal Component Analysis. The results of dataprocessing, seven dimensions of proposals and indicators are obtained. These dimensions are the basiccomponents of indoor quality and security; waste management and safety; water efficiency managementand artificial lighting; suitability of furniture work area and material; application of sensory technologiesand health; the convenience of workspace; and mechanical ventilation and supporting facilities. Thesedimensions and their indicators are expected to be used as a valuation model to identify that buildings havemet the green ergonomic building assessment requirement.

Abstract

Campus open spaces play an important role in supporting social interaction and creating an integrated campus environment. Their provision is adjusted to the function and needs of students for outdoor spaces. This study aims to develop a method used to measure student preferences and activity patterns in utilizing campus open spaces. This study focuses on the development and validation of methods for measuring student preferences and activity patterns in campus open spaces through the design of a questionnaire as a measurement instrument, in order to obtain results that can represent the overall pattern of campus open space utilization. The data used in the design and preparation of this questionnaire are the factors and indicators that form campus open spaces, which have been identified in previous studies. Data were collected through the distribution of questionnaires, to be analyzed using statistical tests in the next stage. Statistical tests were conducted to test the correlation between the function of open spaces, factors, and indicators of campus open spaces with the landscape elements that form them. Through this statistical test, elements that have a significant correlation in creating campus open spaces that are in accordance with student preferences can be identified. The results of this study include the methods used for data collection that can later be used in statistical tests, in order to gain further insight into the preferences and patterns of campus open space utilization by students.

Abstract

This study aims to analyze the effectiveness of the AfterTreatment machine maintenance at PT XYZ using the Overall Equipment Effectiveness (OEE) and Six Big Losses methods. The AfterTreatment machine is a crucial part of the rayon fiber production process but has been experiencing a high level of downtime. The OEE method is used to measure machine effectiveness based on three key components: availability, performance efficiency, and quality. Data was collected from machine operations between September 2024 and February 2025. The results show that the average OEE value is 75.99%, which is below the world-class standard of 85%. The primary causes of low OEE are losses due to reduced speed, equipment failure, and idling & minor stoppages. By identifying the loss causes through the Six Big Losses and Fishbone Diagram methods, this research proposes improvements including preventive maintenance planning and enhanced operator training. The study concludes that machine effectiveness can be improved by minimizing major losses and optimizing maintenance strategies.
