Mangrove ecosystems are crucial for mitigating climate change by sequestering significant amounts of carbon, providing habitat for diverse species, and protecting coastal areas. Their sustainability is vital for global environmental balance and human welfare. Analysis using the Eidos system reveals the threats to mangrove forest health, considering both negative and positive factors and analyzing the strength and direction of each threat's influence. The Eidos system facilitated the development of a statistical model and cognitive system, demonstrating effectiveness in identifying and classifying degradation risks based on empirical data, allowing for early predictions at relatively low operational costs. These findings can be leveraged by coastal protection organizations worldwide, as the Eidos system is freely accessible online in multiple languages. The results have the potential to inform targeted mangrove conservation policies and enhance environmental protection initiatives in various regions.

This study investigates the implementation of the Case Method and Team-Based Project learning approaches within the context of the Geography Education Department's cultural and political geography courses at Universitas Negeri Medan. These methods, relevant to the Merdeka Belajar - Kampus Merdeka (MBKM) program, aim to enhance student skills through active, applied learning. Employing a qualitative descriptive approach, the research gathered data via questionnaires distributed through Google Forms to a sample of 67 students out of a total population of 454 from the 2019-2022 academic cohorts. Findings indicate that the duration required for the Case Method varies with the complexity of the cases, ranging from 15-30 minutes for simpler issues to over 60 minutes for more intricate problems. The Team-Based Project approach necessitates 7 to 8 meetings, including initial planning and subsequent implementation phases, monitored by lecturers through direct communication or digital platforms like LMS forums or Zoom channels. However, the study reveals inefficiencies in applying these learning methods within the department, attributed to the substantial workload imposed by the Indonesian National Qualifications Framework (KKNI) and a lack of student engagement in assignments. It suggests a comprehensive revision of IQF assignments towards more discussion-oriented and field-practical approaches to address these challenges.
