This study examines the application of the Problem Based Learning model combined with the interactive learning media Articulate Storyline in the learning of Science on the subject of Harmony in Ecosystems in class V of SDN Tamansari 1. The background of this study is based on the low student learning outcomes caused by the dominance of the lecture method and the minimal use of interesting media, so that students are less actively involved in learning. The purpose of this study is to describe the application of the media and improve student learning outcomes. The study used the Classroom Action Research method which was carried out in two cycles, including the planning, implementation, observation, and reflection stages, with 17 students as subjects. The results showed a significant increase in student learning outcomes in each cycle, where the average class score increased from 50 in the pre-cycle to 71.17 in Cycle I, and reached 91.76 in Cycle II. The percentage of learning completion also increased from 17.65% to 76.47%, until finally reaching 100% in Cycle II. These findings indicate that the use of the Problem Based Learning model combined with Articulate Storyline can encourage student engagement and deepen conceptual understanding. Therefore, it can be concluded that the implementation of these learning models and media is effective in improving science students' learning outcomes.

The implementation of active learning models such as Problem-Based Learning (PBL) and Project-Based Learning (PjBL) at the junior high school level is often constrained by the complexity of instructional time management. This study aims to examine the role of the principal’s instructional leadership in addressing time management dilemmas in the implementation of active learning at SMP Negeri 6 Panyabungan. A qualitative approach with a descriptive method was employed in this study. Data were collected through non-participant observation and in-depth interviews with key informants, namely the school principal and an Islamic Religious Education (PAI) teacher selected as representatives of field conditions. The findings reveal three main results. First, teachers’ time management constraints are caused by weak control of learning activity transitions, noisy classroom conditions during group division, and low initial student learning readiness. Second, the principal implemented several concrete interventions, including the adoption of block scheduling, clinical supervision focused on classroom management, and the optimization of the Subject Teacher Forum (MGMP) or school learning community. Third, these interventions improved teachers’ instructional efficiency, strengthened classroom activity control, and created a more structured active learning process. However, sustainability challenges remain, particularly resistance from senior teachers who tend to prefer conventional teaching methods. This study concludes that adaptive and solution-oriented instructional leadership is a key factor in addressing the complexity of time management constraints in active learning implementation.

This study examines the integration of social activities and leadership values in shaping the character of students by the PIJAR Semarang Community as a form of community-based non-formal education. The background of this study stems from the increasing problems with student character, such as low empathy, responsibility, and self-confidence, as well as the increasing cases of violence and bullying in the educational environment. These conditions indicate that formal education has not been fully able to address the challenges of shaping student character. This study uses a qualitative approach with descriptive methods. The research was conducted at the PIJAR Semarang Community by involving community managers, volunteers, and students as research subjects. Data were collected through in-depth interviews, observation of activities, and documentation to obtain a comprehensive understanding of the character-building process. The results of the study show that the PIJAR Semarang Community integrates social activities and leadership values through academic and non-academic learning programs that are designed to be contextual and participatory. Social activities such as play-based learning, social action, field trips, art performances, and leadership training are the main media for instilling character values. The character values developed include responsibility, cooperation, empathy, discipline, and self-confidence. Leadership values are instilled through habit formation, volunteer role models, providing opportunities for participation, and the active involvement of students in every activity. This study also found several obstacles in the form of differences in student character, limited resources, and low self-confidence among some students in leadership. To overcome these obstacles, the PIJAR Semarang Community implemented intensive mentoring, motivation building, and adjustments to activities to make them more inclusive. Overall, this study confirms that the integration of social activities and leadership values in community-based non-formal education plays an important role in the holistic and sustainable character building of students.
