Stakeholders, including educators, students, and administrators, reported that participatory decision making fostered a sense of ownership and ensured the relevance of adopted technologies. The study also identifies key sustainability factors, including participatory decision making, long term community engagement, and contextual relevance, which are crucial for ensuring that educational technologies remain effective and beneficial over time. However, challenges such as resistance to change, lack of resources, and unequal access to technology were found to hinder the successful implementation of sustainable models. The research concludes with practical recommendations for educational institutions and policymakers to adopt community aligned models and ensure equitable access to technology. Future research directions are suggested to further explore the balance between institutional innovation and community driven learning, with a focus on long term outcomes and the adaptability of these models across different educational contexts.

This systematic literature review examines the implementation of Content and Language Integrated Learning (CLIL) in Indonesian senior high schools. Following PRISMA guidelines, nine studies published between 2021 and 2025 were analyzed to identify the benefits and challenges of this approach. The findings reveal that CLIL effectively enhances student engagement, motivation, and the integrated development of subject knowledge and English proficiency. However, implementation is often hindered by limited teacher readiness, insufficient collaboration between subject and language teachers, and a lack of appropriate assessment methods. Analysis using the 4Cs Framework shows that while Content and Communication are prioritized, Cognition and Culture receive less explicit attention. The study implies that successful CLIL sustainability requires continuous professional development and stronger institutional support within the Merdeka Curriculum. These results provide a strategic basis for educators and policymakers to optimize bilingual instruction in Indonesia.

The fundamental issue in sustainable tourism management that remains less than optimal can be seen from the limited involvement of local communities and the lack of integrated management of tourism potential in the Pura Maduwe Karang area. The purpose of this study is to analyze sustainable tourism management in the management of Pura Maduwe Karang. This research employs a qualitative approach with a case study method through observation, interviews, literature review, and documentation. The theoretical foundations used include the concepts of Sustainable Tourism, the Triple Bottom Line, and Tourism Impact Theory.The results show that the implementation of sustainable tourism management at Pura Maduwe Karang is still basic and has not been structured professionally. The socio-cultural aspect is relatively well preserved through customary roles and ceremonial activities; however, the economic aspect has not provided significant benefits for individuals in the local community, as contributions remain limited to collective interests of the traditional village. The environmental aspect is currently well maintained due to the temple’s sacred status but may decline if tourist numbers increase without proper management. The main constraints lie in the lack of promotion, facilities, and human resource capacity in management. This study emphasizes the importance of tourism management strategies that balance the dimensions of profit, people, and planet, and encourages collaboration among traditional villages, local governments, and communities to maintain the sustainability of the temple as both a cultural heritage site and a tourist destination.

Learning is the process of children getting to know knowledge that aims to increase knowledge as a basis for forming behavior. The learning process is carried out so that children experience behavioral changes and gain an overall improvement in knowledge, skills, and attitudes. Learning is very closely related to daily life, therefore it is important for children to learn continuously, one of which is through learning mathematics. Mathematics learning has a very important role in the sustainability of children's education because mathematics is one of the fundamental non-physical tools in the world of education and daily life. Through mathematics learning, children are trained to think logically, systematically, critically, and creatively in solving various problems. In addition, mathematics helps children solve calculation problems that are often encountered in daily activities, such as counting money, measuring length, time, and distance, and interpreting simple data. Mathematics learning also plays a role in developing the ability to reason and make appropriate decisions. Therefore, mathematics learning is a subject that must be followed because it has a great influence on thinking skills, learning independence, and children's readiness to face life challenges and scientific development in the future.

This study investigates the long-term impact of adaptive digital learning ecosystems on students' self-regulated learning (SRL) behaviors and academic persistence. Adaptive learning systems personalize the learning experience by adjusting content and feedback to meet individual students' needs, preferences, and performance. These systems enhance engagement, motivation, and learning outcomes through real-time adjustments and continuous feedback. The research aims to explore how adaptive learning systems influence SRL and academic persistence in university courses over time. Using a longitudinal quantitative design, the study tracks SRL behaviors and academic persistence at multiple points during the semester. Results show significant improvements in SRL behaviors such as goal setting, planning, self-monitoring, and reflection among students engaged with adaptive learning environments. These students exhibited greater autonomy, improved metacognitive awareness, and higher motivation. Additionally, students in adaptive systems demonstrated greater academic persistence, as indicated by more time spent on tasks, higher assignment completion rates, and sustained engagement. The findings suggest that adaptive learning platforms promote SRL and academic persistence by offering personalized, responsive learning experiences. Unlike static, non-adaptive environments, adaptive systems provide dynamic support, enhancing students' ability to regulate their learning and remain engaged despite challenges. The study concludes that adaptive learning systems are vital for long-term academic success, though further research is needed to assess the sustainability of these effects in various educational settings and among diverse student populations.
