Abstract

This study investigates energy efficiency challenges during laboratory activities. Inefficient energy use in the practicum phase remains a critical issue, prompting the exploration of innovative forecasting models. This research employs artificial neural network (ANN) models integrated with principal component analysis (PCA) to predict energy consumption and optimize usage. The findings reveal that PCA components, including eigenvalues, eigenvectors, and matrix covariance values, significantly influence the ANN model's performance in forecasting energy production. The ANN training achieved a high correlation coefficient (R=1) with a mean squared error (MSE) of 0.045931 after 200,000 epochs, demonstrating the model's robustness. While testing results showed a moderate correlation (R=0.46169), the models demonstrated potential for refinement and scalability. This integration of ANN and PCA models provides a reliable framework for accurately forecasting energy usage, offering an effective strategy to enhance energy efficiency in laboratory settings. By optimizing energy consumption, this approach has the potential to reduce operational costs and environmental impact. The strong performance metrics highlight the practical utility of these models in educational contexts, contributing to sustainable energy management and better resource allocation. Furthermore, the reduction in energy-related environmental impacts underscores the broader applicability of these models for fostering sustainable development in similar contexts.

Abstract

Developing a scale of interpersonal communication for Muslim students in Indonesia is very important because of the unique cultural and religious context that these students live in. Effective interpersonal communication is essential to fostering a supportive educational environment, improving peer relationships, and improving students' overall well-being. Currently there are no published research findings that specifically discuss measuring interpersonal communication among Muslim students in Indonesia. Therefore, this research aims to develop a valid and reliable Muslim Student Interpersonal Communication Scale (MSICS). MSICS was developed based on five aspects: openness, empathy, supportiveness, positivity, and equality. Content validity was assessed by two psychometric experts, and the results were analyzed using an inter-rater agreement model. Construct validity involved 432 Muslim junior high school students in Yogyakarta City, Indonesia, and the data was analyzed using the Rasch model. The results of the interrater agreement model analysis show that there is agreement between two psychometric experts regarding the acceptability of the statement items in the MSICS. Furthermore, the Rasch model analysis shows that the MSICS appears as a valid and reliable instrument for assessing the level of interpersonal communication among Muslim students in junior high schools in Indonesia with a variance explained by measures value of 26,7% (>20%), which means good enough to describe the measured data, and the reliability value is 0,91, which means very good. The results of this research can be used by counselors or guidance and counseling teachers to use MSICS as an instrument to measure Muslim students' interpersonal communication.

Abstract

In the 21st century, globalization and digital transformation have significantly altered human life patterns. Digital technology has become central to nearly all aspects of life, including the education sector in Indonesia. Technological skills and readiness to meet the demands of the job market have become increasingly critical. Vocational education, such as vocational high schools, aims to equip students with the competencies necessary to compete in the global market. However, challenges in enhancing the quality and relevance of education remain a significant issue. In fact, according to Indonesia’s Central Statistics Agency (BPS), the unemployment rate for vocational high school graduates reached 9.6% in 2023, the highest among all education levels, underscoring the urgent need for innovative approaches in vocational learning. One proposed solution is the development of flipbook-based learning media integrated with Augmented Reality (AR) to enhance student engagement and skills in the digital era. This study employed ADDIE (Analyse, Design, Development, Implementation, Evaluation). The results indicate that the VOCAR-FLIP model is significantly effective in improving students' learning outcomes, particularly in terms of academic achievement and conceptual understanding. These findings are expected to contribute meaningfully to the advancement of more innovative and effective educational technologies for future learning.

Abstract

The "health promoting universities" strategy has gained popularity and a presence in the higher education system, particularly in universities. It is imperative for higher education establishments to prioritize the promotion of health within their student body and academic community. By safeguarding and boosting students' wellbeing, a strategy centered on encouraging healthy lifestyles has the potential to boost the university's contribution to health improvement and offer significant value to the community. Universities have the power to improve health promotion through community service and to make policies in this area through research and teaching. In order to investigate student behavior in relation to the standard aspects of the healthpromoting lifestyle profile, this project will undertake an intervention study involving 150 students with the goal of promoting a healthy lifestyle. A pretest and post-test control group design was employed in this investigation. The health-promoting lifestyle standard profile II questionnaire was the research instrument, and descriptive statistics and inference were employed for analysis at the .05 significant level. The outcomes demonstrated a noteworthy impact on the implemented measures. This study's findings indicated that interventions in learning environments successfully raised student behavior linked to a healthy lifestyle and its components.
