Jurnal Biologi ISSN 3026-7390 combines two crucial aspects of the biology world.Biology education and the practical application of biological science. The journal plays a vital role in supporting the integration of biological science with practical contexts across various fields. This journal aims to bridge the gap between research and practice, providing information, ideas, and opinions, in addition to critical examinations of advances in biology research, teaching, and learning. Through the coverage of policy and curriculum developments, the latest results of research into the teaching, learning and assessment of biology are brought to the fore. Journal of Biology provides an opportunity for researchers, educators, and biology education practitioners to contribute to the development of theory and practice in biology education and bridge the gap between research and teaching

Abstract

Penelitian ini bertujuan untuk mengetahui peningkatan hasil belajar siswa melalui penerapan model pembelajaran Problem Based Learning (PBL) pada materi biologi kelas XF di SMAN 3 Pamekasan. Penelitian tindakan kelas ini di laksanakan terdiri dari dua siklus dengan subjek kelas XF SMAN 3 Pameasan. Penelitian ini di fokuskan pada hasil belajar siswa,data ini di peroleh melalui tes. Hasil penelitian pada siklus I menujukkan 71.43% dan mengalami peningkatan yang signifikan melalui siklus 2 yaitu 88.57% dari 35 siswa. Hal ini menunjukkan bahwa terjadi peningkatan dari pratindakan sebesar 2,86%, peningkatan ini menunujukan adanya kemajuan pemahaman siswa mengenai materi biologi. Penelitian tindakan kelas dengan penerapan model pembelajaran Problem Based Learning (PBL) bisa di katakan berhasil dalam meningkatkan hasil belajar siswa di karenakan ada peningkatan yang signifikan dari siklus 1 ke siklus 2 terjadi peningkatan sebesar 17.14%.

Abstract

This study sought to understand the impact of an alcoholic extract of Artemisia annua on kidney function in experimental diabetic rats. For this study, fifty adult male albino rats were randomly assigned to one of five groups: G1 received unrestricted access to food and water. G2: To induce diabetes, a single intravenous injection of STZ (60 mg/kg) is administered. The third group undergoes insulin subcutaneous injections for four weeks after each STZ injection. The fourth group takes Artemisia annua extract orally (by gavage) at a dose of 75 mg/kg for four weeks following each STZ injection. The fifth group takes insulin subcutaneously (by gavage) and Artemisia annua extracts orally (70 mg/kg) for four weeks following each STZ injection. We took blood samples from the orbital sinus to estimate creatinine, urea, uric acid, SOD, GPX, and CAT in the serum. We extracted the kidneys for histopathological investigation after slaughtering the animals. The current results demonstrated a significant reduction in all kidney functions, including creatinine and urea, as well as uric acid, following treatment with insulin, Artemisia annua extract, or a combination of insulin and extract. According to these results, the amount of SOD in G3, G4, and G5 is significantly higher than in G1 and G2. However, there were no significant differences between the groups in the amounts of GPX and CAT. The histopathological results of the kidney in groups G1 and G4 revealed a normal histological appearance. Kidneys of G2 exhibit glomerular atrophy and interstitial hemorrhage. G3 displayed tubular epithelial degeneration, necrosis, mesangial cell hyperplasia, glomerular atrophy, and inflammatory cell infiltration. The kidney of G5 displays blood vessel dilatation, congestion, glomerular atrophy, and acute swelling of epithelial cells. In conclusion, the alcoholic extract of Artemisia annua reduces the kidney function in experimental diabetic rats and can alleviate the histological damage of diabetes on renal tissue.
