Abstract: This study aims to analyze the influence of leadership style, organizational culture, and work motivation on organizational commitment among library staff of public senior high schools (SMA Negeri) in Jambi Province, both… h directly and indirectly. The research employed a quantitative approach with a cluster sampling technique across three regions Jambi City, Tanjung Jabung Timur Regency, and Merangin Regencywith a total of 132 respondents, 97 of whom were included in the analytical sample. Data were processed using SmartPLS 3.0 through structural model testing (inner model) to examine causal relationships among variables.The results indicate that leadership style does not have a significant direct effect on work motivation, whereas organizational culture shows a strong and significant direct effect on the work motivation of library staff. Additionally, leadership style and organizational culture jointly have a significant impact on work motivation. Regarding organizational commitment, the findings reveal that leadership style, organizational culture, and work motivation each have a positive and significant direct effect. Further results show that both leadership style and organizational culture exert significant indirect effects on organizational commitment through work motivation, suggesting that work motivation functions as a mediating variable in these relationships. Overall, this study concludes that organizational culture is the most dominant factor influencing both work motivation and organizational commitment, while work motivation strengthens the relationship between leadership and cultural factors and the commitment of library staff. Therefore, efforts to enhance organizational commitment among library personnel in public senior high schools in Jambi Province should focus on cultivating a positive organizational culture, improving effective leadership practices, and providing continuous motivational support.

Implementasi Algoritma K-Means Clustering untuk Mengelompokkan Siswa Berdasarkan Nilai sebagai Evaluasi Pembelajaran

Jihan Aulia Putri Fahdrina, Eva Lestari, Dila Sari
Abstract: Academic achievement is a measure of students' learning outcomes, encompassing aspects of knowledge and skills. Academic performance serves as a crucial indicator in evaluating students' learning progress. MAS Al-Wasliyah… h Petatal is committed to providing quality education but still faces limitations in applying technology to evaluate student learning. The current evaluation process relies on teachers' subjective assessments, which restricts the information about students' progress. Therefore, the implementation of machine learning is proposed as a solution to enhance objectivity in student learning evaluation through more effective data processing. The method used is the K-Means Clustering algorithm, which can group or classify data based on specific patterns. This study aims to evaluate the extent to which machine learning can process student learning evaluation data through the analysis results obtained from the clustering process, which are then used as benchmarks to improve the evaluation system and provide feedback for students needing improvement in their academic performance. The data used comprises students' grades from the odd semester of the 2024/2025 academic year, with a total of 210 data points. The clustering results produced three clusters: the "good" cluster with 60 students, the "average" cluster with 99 students, and the "low" cluster with 51 students.

Analisis Bibliometrik: Gaya Kepemimpinan dalam Penguatan Budaya Sekolah di Sekolah Islam

Robby Haryanto, Rugaiyah, Kamaludin
Abstract: Research on leadership styles and the strengthening of school culture in Islamic schools has become increasingly significant in response to the growing demand for educational quality grounded in religious values. School… principals play a strategic role in developing an adaptive, collaborative, and character-oriented organizational culture that supports students’ holistic development. This study focuses on publication trends, thematic cluster structures, and the tendencies of leadership style implementation in strengthening Islamic school culture based on bibliometric analysis. The study employed a descriptive quantitative approach using bibliometric analysis of 397 Scopus-indexed documents published between 2019-2025. Data collection was conducted using Publish or Perish, while data visualization analysis was performed using VOSviewer through keyword co-occurrence techniques. The findings reveal that school culture and distributed leadership emerged as the most dominant themes and occupied central positions within the bibliometric network. The shift in research paradigms indicates a transition from structural approaches toward participatory, collaborative, and contextual approaches in modern educational leadership. Another finding demonstrates that the concepts of Islamic school and Islamic leadership have not yet appeared prominently in international research networks, thereby indicating a significant research gap regarding the integration of Islamic values into school culture and educational leadership practices. This study concludes that the strengthening of school culture is influenced not only by the administrative capabilities of school principals, but also by their ability to foster collaboration, social relations, innovation, and the continuous internalization of moral values. The novelty of this research lies in the use of bibliometric analysis to systematically map the relationship between leadership styles and Islamic school culture, while also offering a perspective on integrating the values of amanah, shura, and exemplary conduct into modern collaborative leadership models.
