Abstract

The COVID-19 pandemic has impacted all aspects of life, including teaching and learning activities. Therefore, the entire community must be ready to do online learning, which will have different processes and results from normal learning. This study aims to determine the level of student satisfaction in online learning during the pandemic. This study uses attributes on Webqual 4.0 and processed using the integration of IPA and Kano. Based on the results of research conducted on 194 respondents, it was found that attributes US1 and IT4 were in the Beginning jewelry category, IT7 attributes were in the Defenseless Strategy point category, IT2 attributes were in the Fatal category, attributes IF1, IF2, IT3 was in the Major weapon category, attributes IF4, IF5 are included in the precious treasure category, and other attributes are included in the removed category because they have the Kano Indifferent category.

Abstract

This study evaluates the usability of three widely used 3D printing slicer software, Ultimaker Cura, IdeaMaker, and PrusaSlicer, at the Engineering Drawing Laboratory of UPN “Veteran” Yogyakarta. A mixed-methods approach was applied, combining the System Usability Scale (SUS) and the USE Questionnaire (Which Assesses Usefulness, Ease of Use, Ease of Learning, and Satisfaction), as well as direct observation of three UX dimensions: learnability, effectiveness, and efficiency. Nine respondents completed seven task scenarios, each with six repetitions. To compare the three software, statistical analysis was conducted using the Friedman test and Wilcoxon post-hoc comparisons. The results showed that Ultimaker Cura consistently achieved the highest SUS and USE scores and demonstrated significantly faster task completion times. The strong alignment between observed performance and user perception supports the validity of the blended evaluation method. This study concludes that Ultimaker Cura is the most user-friendly option for beginners and is well-suited for educational environments. This finding contributes to provide guidance in selecting software and teaching practices in educational laboratories, while also contributing to usability research.
