Abstract

Flipped classroom merupakan pendekatan pembelajaran di mana isi materi dan keterampilan yang biasanya diajarkan selama sesi kelas disampaikan di luar kelas. Penelitian ini bertujuan untuk mengevaluasi peningkatan hasil belajar mahasiswa dengan menggunakan model pembelajaran flipped classroom pada materi stokiometri dalam kuliah kimia dasar. Metode penelitian yang digunakan adalah penelitian kuantitatif dengan metode eksperimen dan desain one-group pretest-posttest. Sampel penelitian terdiri dari 35 mahasiswa kelas A di program studi pendidikan matematika Universitas Negeri Manado (Unima). Data dikumpulkan melalui tes hasil belajar dengan memberikan pretest sebelum proses perkuliahan dan posttest setelah proses perkuliahan dilaksanakan. Hasil penelitian menunjukkan bahwa rata-rata hasil belajar mahasiswa pada pretest adalah 49,33, sedangkan pada posttest meningkat menjadi 87,33. Pengujian N-Gain score menunjukkan skor sebesar 77%, yang masuk dalam kategori efektif dan tinggi. Berdasarkan temuan tersebut, dapat disimpulkan bahwa penerapan model flipped classroom secara efektif dan signifikan meningkatkan hasil belajar mahasiswa pada materi stokiometri dalam kuliah kimia dasar di program studi pendidikan matematika Unima.

Abstract

Background/problems: Biodiesel from animal fats is vulnerable to metal-catalyzed oxidation that degrades fuel quality because of the unsaturated fatty acid content. This study investigates the oxidative stability and physicochemical changes of chicken fat and its biodiesel upon FeCl₃-catalyzed oxidation. Methods: Chicken fat was transesterified to produce biodiesel; chicken fat (CF) and chicken-fat biodiesel (CF-BD) were then subjected to an FeCl₃ oxidative condition. Acid value (AV), iodine value (IV), peroxide value (PV), kinematic viscosity at 40 °C, and density were determined using standard titrimetric and physical methods; FTIR assessed spectral changes. ANOVA compared group means. Findings: Oxidation significantly increased AV and PV for both matrices, with a marked PV rise in CF-BD (6.17 ± 0.29 to 88.17 ± 5.35 meq/kg), and decreased IV (CF-BD 84.3 ± 4.51 to 48.7 ± 4.32 g I₂/100 g). Viscosity and density increased modestly. Visually, CF-BD shifted from clear yellow-green to brown and turbid with sediment, consistent with polymer formation and methyl-ester degradation. FTIR showed attenuation/shift of ester carbonyl and aliphatic bands. Conclusion: FeCl₃-induced oxidation measurably deteriorates CF-BD quality, breaching key limits in ASTM/SNI for acid value and viscosity. Impact: Results underscore the need to control trace metals and apply antioxidant/metal-deactivator strategies in storage and distribution, and validate the FeCl₃ assay as a practical accelerated-degradation model for stability and additive screening.
