Abstract

Excessive consumption of sopi in the long term can cause various chronic diseases such as kidney failure. This study aims to determine the potential of African leaf ethanol extract in repairing sopi-induced kidney damage in white rats. The experimental design used was a completely randomized design (CRD) with five treatments. The sample was 18 mice. Groups of mice K (-), K (+), P1, P2 and P3 were induced with 1.28 ml of sopi/animal. K (+) mice were given Furosemide as a comparison. Groups P1, P2 and P3 were given ethanol extract of African leaves at doses of 1.28, 2.56 and 5.12 ml/head/day respectively. The results obtained were analyzed using analysis of variance (ANOVA) then followed by the Tukey HSD post hoc test. The results of the study showed that there was an effect of reducing creatinine levels and improving kidney damage in white mice due to administration of African leaf ethanol extract, where the effective dose was 2.56ml/head/day. So it can be concluded that the ethanol extract of African leaves at a dose of 2.56 ml/head/day has the potential to reduce creatinine levels and repair sopi-induced kidney damage in white rats, the results of which are also the same as those shown by the drug Furosemide. However, giving higher doses will be toxic to the body.

Abstract

Student learning outcomes are still a challenge in higher education, especially in a learning system that is still teacher-centered and lack interactivity. Therefore, it is necessary to improve the quality of learning through more responsive and flexible approaches, such as blended learning. This study aims to analyze the effect of implementing blended learning on the learning outcomes of biology students in the Faculty of Mathematics and Natural Sciences (FMIPA) at the University of Makassar (UNM). This study employed a quasi-experimental design with random sampling. The study population consisted of all Biology Department students at FMIPA UNM enrolled in the Cell and Molecular Biology course. The sample comprised 75 students divided into three classes: two experimental classes and one control class. The assessment instrument used was a learning outcome test in the form of multiple-choice questions. Data analysis was conducted descriptively and inferentially using a one-way ANOVA test. The results showed that Experimental Class 1, which implemented blended learning, achieved a higher average learning outcome score compared to Experimental Class 2 and the control class. The ANOVA test indicated a significant difference between the groups (p < 0.05). Thus, blended learning has a significant effect on student learning outcomes.
