Abstract

A thin film is a material with optical properties highly dependent on the dielectric constant, refractive index, and gap energy. This research aims to identify and analyze research trends in thin-layer synthesis as electronic devices. This research is qualitative. The data used in this research was obtained from documents indexed by Google Scholar from 2014-2023 using Publish or Perish and Dimension.ai. Research procedures use PRISMA guidelines. The data identified and analyzed included the type of publication, author on thin layer synthesis, source of publication, and the title of research on thin layer synthesis that was widely cited. The data analysis method uses bibliometric analysis assisted by VOSviewer software. The results of the study show that the research trend in thin-layer synthesis has experienced a fluctuating increase from 2014 to 2020. The journal containing the most thin-layer synthesis articles is ECS Meeting Abstracts with 676. The results of the density mapping analysis show that the theme that is rarely researched is organic semiconductors, organic thin film transistors, and green synthesis.

Abstract

This research aims to develop a physics e-book discovery learning model containing Al-Qur’an values to improve students' problem-solving skills and spiritual attitudes. This research is included in the Research and Development type. This research refers to the 4D research and development model which consists of four development stages, there are define, design, develop, and disseminate. The resulting product development went through several test stages including validity and reliability testing, limited testing, and extensive testing. The validity test results show that the product is in the very valid category. In limited trials, it was seen that the product developed provided students with practical use in the classroom learning process. In extensive trials, it appears that the product being developed has a positive influence in improving students' spiritual attitudes and problem-solving skills. This is demonstrated based on the results of the effectiveness tests that have been carried out. Spiritual attitude is in the medium category, while problem-solving skills are in the high category. This research concludes that the development of a physics e-book discovery learning model containing Al-Qur’an values is able to improve students' problem-solving skills and spiritual attitudes.

Abstract

The transformation of education in the digital era requires prospective teacher students to possess competencies in utilizing innovative learning technologies that are relevant to the needs of 21st-century education. This academic community service activity aimed to strengthen the competencies of students in the Undergraduate Physics Education Study Program, Faculty of Teacher Training and Education, University of Mataram, through the implementation of a guest lecture themed Artificial Intelligence (AI), Augmented Reality (AR), and STEM in physics learning. The activity was conducted on April 28, 2026, in a hybrid format involving two guest speakers. The implementation method consisted of three stages: preparation, implementation, and evaluation. The evaluation was conducted through a Google Form-based questionnaire distributed to participants to measure their responses regarding material content, speakers, implementation, benefits, and the impact of the activity on students’ level of understanding. A total of 131 participants attended the activity, consisting of students from various semesters and alumni. The results showed that the majority of participants gave positive responses regarding the relevance of the materials, the competence of the speakers, the quality of implementation, and the benefits of the activity in improving learning motivation, academic insight, technological literacy, and readiness as prospective physics teachers in the digital era. In addition, participants perceived that the materials on AI, AR, and STEM integration provided contextual and applicable learning experiences. This activity was proven effective in strengthening the competencies of Physics Education students and contributing to the achievement of the Sustainable Development Goals (SDGs), particularly in quality education, while also supporting the implementation of the Impactful Campus program in higher education.

Abstract

The study aims to determine the influence of teacher personality competence on teacher performance, the influence of motivation on teacher performance, the influence of the work environment on teacher performance, and the combined influence of teacher personality competence, motivation, and work environment on teacher performance in Cluster 2. The study adopts a quantitative approach using a survey research method and an experimental research design. Data collection is conducted using a questionnaire technique. The population of this study consists of all teachers in Cluster 2, totaling 45 individuals. The sample is selected using the census of saturation sampling method, resulting in a sample size equal to the population, which is 45 individuals. Data collection is performed through questionnares, and data analysis includes descriptive analysis, multiple linear regression analysis, t-test, and F-test. The findings of this study indicate that teacher personality competence has significant influence on teacher performance in Cluster 2, as the significance value (t) is 0,000, which is smaller than α= 0,005, with a regression coefficient of 0,332. The work environment has a significant influence on teacher performance in Cluster 2, as the significance value (t) is 0,000, which is smaller than α= 0,005, with a regression coefficient of 0,223. Furthermore, the combined influence of teacher personality competence, motivation, and work environment significantly affect teacher performance in Cluster 2.
