Abstract

Daun alpukat (Persea americana Mill) merupakan tanaman yang sudah sejak lama dikenal masyarakat Indonesia serta digunakan sebagai obat tradisional untuk mengobati berbagai macam penyakit. Salah satunya adalah sebagai antimikroba. Penelitian ini bertujuan untuk mengetahui aktivitas antimikroba dan konsentrasi efektif dari ekstrak daun alpukat. Pengujian daun alpukat ini menggunakan metode disc diffusion dengan mengamati Konsentrasi Hambat. Bakteri yang diujikan adalah P. acnes dan P. ovale. Konsentrasi yang digunakan yakni 25%, 50%, 75%, dan 100%. Hasil penelitian menunjukkan adanya potensi antimikroba pada semua ekstrak daun alpukat yang ditunjukkan dengan adanya zona bening di sekitar paper disk. Zona bening terbesar adalah 19,52 mm dan 17,60 mm diperoleh dari ekstrak daun alpukat dengan konsentrasi 100% pada isolat P. acnes dan P. ovale.

Abstract

Progressive Tests are structured, longitudinal formative assessments used globally to evaluate knowledge retention and cognitive development in medical education. While they are increasingly integrated into curricula, limited empirical data exists regarding their predictive validity within Indonesian private medical institutions. Evaluating their impact on academic performance is essential to refine assessment strategies and promote effective learning. This study investigates the influence of Progressive Test scores on the academic performance of medical students at the Faculty of Medicine, Dentistry, and Health Sciences (FKKGIK), Universitas Prima Indonesia during the 2024 academic year. A quantitative, cross-sectional study was conducted using academic records from 160 randomly selected preclinical students. Progressive Test scores were used as the independent variable, while Cumulative Grade Point Average (CGPA) represented the dependent variable. Pearson’s correlation analysis was conducted using SPSS version 27, with a significance level of p < 0.05. The average Progressive Test score was 40.58 (SD ±10.2), and the mean CGPA was 3.30 (SD ±0.28). A strong, positive, and statistically significant correlation was found between Progressive Test scores and CGPA (r = 0.757, R² = 0.573, p < 0.001). These findings indicate that Progressive Test performance significantly predicts academic achievement, explaining 57.3% of the variance in CGPA. Progressive Tests demonstrate strong predictive value for student performance and serve as an effective tool for curriculum monitoring and early academic intervention. Institutionalizing their use in Indonesian medical schools is recommended. Future multicenter and longitudinal studies are suggested to broaden applicability and assess additional influencing factors.
