Abstract

The industrial revolution and mass production directly increased human productivity and significantly impacted the environment. Amid these environmental problems, companies created environmentally friendly production strategies and prioritized economic factors (profit) and how they impact the social environment. This makes sustainable supply chain management in Sustainable Supplier Selection (SSS) increasingly in demand because it can affect the company's environmental performance. Companies that can improve their environmental and social performance will be able to increase their competitive advantage and impact, increasing revenue, market share, and a more positive green image of the company. There is no research on sustainable supplier selection in the sarong industry, especially in Indonesia. Therefore, research is needed on the sector because it dramatically affects environmental performance. One of the companies engaged in the sarong industry is XYZ company. This study aims to evaluate Supplier performance based on sustainable aspects (economic, environmental, social) using the cut-off point method for selecting sub-criteria, FAHP for assigning sub-criteria weights, and TOPSIS for ranking Suppliers based on predetermined sub-criteria. As a result of data processing, suppliers are ranked based on their preferences. As a result, Supplier 2 (S2) ranked first with a preference value of 0.9210, followed by Supplier 1 (S1) with a preference value of 0.7514, Supplier 3 (S3) with a preference value of 0.3166, and Supplier 4 (S4) with a preference value of 0.00019.

Abstract

In the current era of globalization, rapid advancements are driving nations to compete in strengthening their economies. Companies and industrial enterprises play a vital role as economic units actively contributing to national economic activities. Economic growth is closely associated with the output value of industries, which is significantly influenced by the number of workers. This study aims to examine the effect of the number of workers in micro-industries on the output value of micro-industries in Indonesia. The research employs two variables: the independent variable (X), representing the number of micro-industry workers, and the dependent variable (Y), representing the output value of micro-industries. A simple linear regression analysis was applied to measure the extent of the relationship between these variables. The results show a regression equation of Y = 217.512,365 + 46,669X with a coefficient of determination (R²) of 0,896, indicating that 89,6% of the variation in output value can be explained by the number of micro-industry workers. This suggests a strong influence of labor quantity on micro-industry output in Indonesia.

Abstract

This study's goal was to compare the usability of the websites for the Industrial Engineering and Chemical Engineering departments at a university. Since these sites are critical for new students seeking information, a user-friendly interface is essential for efficient and accurate information retrieval. To conduct the study, a user performance test was administered to 40 new students, all with less than a year of study. They were asked to complete three specific tasks: downloading a form, finding a "kaleidoscope" (a summary of activities), and locating information about oral exam registration. The researchers collected data on the time students took to complete the tasks (efficiency) and the number of errors they made. This data was t hen analyzed using a Two-Way ANOVA statistical method. The results showed significant differences in usability between the two websites, with a very strong interaction effect for both efficiency and error rates. The Industrial Engineering website was most efficient for downloading a form but proved to be the least efficient for finding the kaleidoscope. Conversely, the Chemical Engineering website was most efficient for finding the kaleidoscope but was the least efficient for form downloads. Regarding errors, finding the kaleidoscope and downloading a form presented the most significant challenges, while registering for the oral exam was the least error-prone task. These findings highlight the importance of making specific, tailored improvements to academic web design to enhance the user experience on these platforms.   Keywords – Usability; University Website; User Experience; Efficiency; Error Rates
