Mangrove fruit (Rhizophora mucronata Lamk.) has a good bioactive and antioxidant compound. Mangrove fruits are usually extracted with methanol solvent and thus it’s necessary to investigate the influence of different solvents on their antioxidant activity. The purpose of this research was to study the effect of solvent polarity on the antioxidant activity of mangrove fruit extract. The solvent used was n-hexane (nonpolar), ethyl acetate (semi-polar), and methanol (polar). Antioxidant activity was measured by the DPPH method. The polarity of the solvents significantly affected the IC50 values of mangrove fruit extract. IC50 values from n-hexane, ethyl acetate, and methanol extracts were 354,83 ppm, 120,19 ppm, and 58,61 ppm respectively. The crude extract (methanol) can inhibit fat oxidation and achieve the best peroxide number of 3.00 mEq/kg oil, which was lowered at a concentration of 31.25 ppm. Methanol extract and Ethyl acetate contained bioactive compounds such as alkaloids, steroids, flavonoids, phenols hydroquinone, and, tannins. N-hexane extract had steroids. The best solvent to produce the highest antioxidant activity and inhibit peroxide was methanol. Keywords: Bioactive compound, mangrove fruit, polarity Abstrak Buah Bakau (Rhizophora mucronata Lamk.) memiliki komponen bioaktif dan aktivitas antioksidan yang baik. Umumnya buah bakau diekstrak dengan menggunakan metanol, sehingga perlu dilakukan penelitian untuk mengetahui pengaruh perbedaan pelarut terhadap aktivitas antioksidan buah bakau. Tujuan dari penelitian ini adalah untuk menentukan aktivitas antioksidan dari buah bakau dengan metode DPPH yang diekstraksi dengan tiga macam pelarut berbeda yaitu, n-heksana (nonpolar), etil asetat (semi polar) dan metanol (polar). Nilai IC50 ekstrak kasar buah bakau dipengaruhi secara signifikan oleh tingkat kepolaran pelarut. Nilai IC50 dari ekstrak kasar n-heksana sebesar 354,83 ppm, ekstrak kasar etil asetat sebesar 120,19 ppm dan ekstrak kasar metanol sebesar 58,61 ppm. Ekstrak kasar (metanol) dapat menghambat oksidasi lemak dan menghasilkan nilai bilangan peroksida terbaik sebesar 3,00 Meq/Kg minyak yang dapat diturunkan pada konsentrasi 31,25 ppm. Ekstrak kasar metanol dan etil asetat mengandung komponen bioaktif alkaloid, steroid, flavonoid, fenol hidrokuinon dan tannin. Ekstrak kasar n-heksana mengandung komponen bioaktif yaitu steroid. Pelarut terbaik yang dapat menghasilkan aktivitas antioksidan tertinggi serta dapat menghambat bilangan peroksida terbaik adalah metanol. Kata kunci: komponen bioaktif, Buah bakau, kepolaran.

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.
