Abstract

This research aims to investigate the effect of using Spent Bleaching Earth (SBE) as a soil stabilizer in cement-stabilized soil. The study employs a 5% Portland Composite Cement (PCC) ratio based on the dry soil weight, with SBE as a stabilizing agent at ratios of 5%, 10%, 15%, and 20% of the Portland Composite Cement weight. Curing periods of 0 days, 7 days, and 14 days are used, with a focus on the expansion and shrinkage characteristics. The best results were obtained in a mixture with a 10% SBE variation as a soil stabilizer, under a 14-day curing period, with a plasticity index of 14.149%, Expansion (CBR Soaked) of 1.178, Expansion Pressure of 1,706 kg/cm2, and free expansion index of 13.333%. Test results indicate that mixtures with various amounts of SBE as a soil stabilizer in cement-treated soil and different curing periods can reduce soil expansion, as evidenced by decreasing values of plasticity index, Expansion (CBR Soaked), expansion pressure, and free expansion index. Therefore, it can be concluded that SBE as a soil stabilizer, along with prolonged curing, can reduce the soil's expansion and shrinkage characteristics.

Abstract

This study aims to explore the role of school principals in integrating technology into teaching and learning, the challenges encountered in the process, and the competencies required for principals to lead digital transformation. A qualitative method with a case study approach was employed in several schools in Indonesia. Data were collected through in-depth interviews with principals, teachers, and students, as well as document analysis related to school technology policies. The findings indicate that principals with a clear vision and adequate technological competence are able to foster the successful integration of technology in instruction. Key challenges include teachers’ resistance to change, limited resources and infrastructure, and the lack of ongoing professional development for teachers. Principals who address these barriers by providing sufficient support, continuous training, and cultivating a culture of innovation can accelerate schools’ digital transformation. Moreover, principals’ technological competencies play an important role in motivating and facilitating teachers to integrate technology. The study offers recommendations for principals to adopt transformational leadership and to place greater emphasis on teacher professional development and the enhancement of technological infrastructure. It is hoped that this research provides insights for education policymakers and school leaders to strengthen technology implementation in schools.

Abstract

This study aims to explore the strategies used by teachers to foster students’ interest in learning Arabic at SMP Muhammadiyah Plus Salatiga. The research employs a qualitative descriptive method with data collected through observation, interviews, and documentation. Three different learning strategies were implemented based on grade levels: roleplay activities in Grade VII, the talking stick method in Grade VIII, and the use of Kahoot as an evaluation tool in Grade IX. The findings reveal that each learning strategy effectively increases students' engagement and interest in learning Arabic. Roleplay helps students develop confidence and improve speaking skills by actively participating in simulated conversations. The talking stick method promotes focus and participation by encouraging spontaneous responses during class discussions. Meanwhile, Kahoot provides a modern and interactive evaluation platform that motivates students through its competitive and game-based format. Overall, this study highlights the importance of using varied and interactive teaching strategies to enhance students’ motivation and learning outcomes in Arabic language classes. The results also emphasize the teacher's role as a facilitator in creating a conducive and enjoyable learning environment.
