Abstract

The increasing adoption of digital beauty technology through Virtual Try-On (VTO) platforms powered by artificial intelligence (AI), augmented reality (AR), and virtual reality (VR) necessitates a precise understanding of user preferences. This study aims to model user responses to VTO features using Item Response Theory (IRT), specifically the Graded Response Model (GRM) for ordinal-scale items and the Nominal Response Model (NRM) for non-ordinal categorical items. A total of 15 items were analyzed using GRM to assess users’ perceptions of AI accuracy, feature convenience, and visual satisfaction. Additionally, five non-ordinal items were modeled using NRM to capture explicit preferences for specific VTO functionalities, such as digital interaction and visual simulation. The results show that the average user preference score was 3.02 out of 5 (SD = 1.03), while the total preference score averaged 60 out of 100 (SD = 10.7), with response distributions approximately normal (skewness = 0.12; kurtosis = -0.24). The item information curves from the GRM indicated that several items contributed high information (above 2.0), effectively differentiating users within the −1 to +1 ability range. In the NRM analysis, the “real-time color visualization feature” exhibited the highest utility parameter (c = 1.98), indicating a strong user preference for this feature. The integration of GRM and NRM enables a more nuanced and flexible mapping of user preferences. This study presents a novel psychometric approach by combining GRM and NRM within a single VTO context to simultaneously capture both ordinal and nominal dimensions of user experience, which has not been extensively explored in prior research. These findings provide meaningful insights for the development of adaptive, personalized, and intelligent AI-based VTO systems to enhance the quality of user experience in digital beauty applications.

Abstract

Teachers at SD Inpres Bonto-Bontoa currently employ conventional teaching models, while students are more inclined towards technology-based instruction. Therefore, efforts are needed to bridge this gap through the implementation of training sessions. The objective of this community service is to provide training to elementary school teachers on the application of teaching methods using the Canva for Education application, aiming to make the teaching methods applied by teachers more engaging. The community service was carried out directly in the IT Room of SD Inpres Bonto-Bontoa, involving 20 teachers and attended by school supervisors, the principal, several professors, and assisted by students. The implementation of community service at SD Inpres Bonto-Bontoa, facilitated in the form of Canva For Education training, has had a positive impact on enhancing teachers' skills in developing teaching materials, serving as a crucial step in technology adaptation within the education environment.

Abstract

The purpose of this study was to analyze the needs of students and teachers in developing a learning media in the form of a trainer to support the sensor and transducer practicum process during the Covid-19 Pandemic. This type of research is quantitative research with descriptive statistical analysis techniques. Data were collected through questionnaires distributed online to 75 respondents, including productive electronic engineering and electrical engineering teachers at SMK Negeri 2 and SMK Negeri 10 Makassar and their students. In addition, there were also respondents from electronic engineering students at the two schools. This study indicates that facilities and infrastructure in schools are in the high category with a percentage of 64%. Learning conditions during the Covid-19 Pandemic based on data from respondents are in the medium category with a percentage of 67%. The level of need for IoT-based sensor trainer learning media to support distance learning at SMK Negeri 2 Makassar and SMK Negeri 10 Makassar is in the high category with a percentage of 72%. Based on this value, it can be concluded that practicum facilities are needed in the form of IoT-based sensors and transducer trainers that can be used as alternative learning during the Covid-19 Pandemic. It is hoped that the teachers can adjust learning tools according to pandemic conditions so that the implementation of the learning process can run smoothly.

Abstract

Background. Exploratory factor analysis can be used as a guideline for constructing instrument homogeneity. Purpose. Factor analysis is the queen of analytical methods because of its strength, flexibility and closeness to the nature of scientific aims and objectives. Method. Roughly speaking, an instrument whose items measure only one trait in general and can determine the indicators of a research variable. To determine the number of indicators based on eigenvalues greater than or equal to one, both in the initial factor analysis and in further analysis. Results. A statement item is declared eligible for inclusion in a factor if the item has a factor load greater than or equal to 0.30 on only one factor. Similarly, an indicator is declared feasible if its factor load is greater than or equal to 0.30. Conclusion. The item that has the highest factor load on a factor contributes the most to that factor, so that item is used as the basis for guidance in naming a factor as the name of the indicator.
