Abstract

The rapid development of digital technology in education demands innovative learning models that combine flexibility, interactivity, and collaboration to enhance student engagement and learning outcomes. This classroom action research aimed to analyze the effectiveness of a blended learning model integrated with the cooperative Teams Games Tournament (TGT) approach in improving students’ learning outcomes and active participation in Biology subjects. The study was conducted in two cycles involving 28 students of class XI H at SMAN 4 Palu during the 2024/2025 academic year. Data were collected through observation sheets and cognitive learning tests. The results showed a significant improvement in both teacher performance and student learning outcomes. The average teacher activity increased from 78.2% (Good) to 93.7% (Very Good), while students’ classical mastery rose from 53.57% to 79%, with the N-Gain improving from “Low” (0.29) to “Moderate” (0.49). Statistical analysis using the Wilcoxon Signed-Rank test confirmed a significant difference between pre-test and post-test scores (p < 0.001), with an effect size (r = -1.000) categorized as very large. Additionally, students’ active participation increased from “Fairly Active” to “Active” in most aspects. These findings indicate that integrating blended learning with the TGT model effectively enhances both cognitive achievement and engagement in Biology learning.

Abstract

This study aims to determine the effectiveness of aloe vera extract (Aloe vera L.) against Colletotrichum capsici fungus and determine the optimal concentration of aloe vera extract that effectively inhibits the growth  of Colletotrichum capsici fungus and is used as a learning medium. This study used a laboratory experiment method using a Complete Random Design (RAL) with 5 treatments and 4 replicates. The treatment consisted of a concentration of 0% as a negative control, a concentration of aloe vera extract of 25%, 50%, 75% and 100%. The observed parameter is the diameter of the formed inhibition zone. The results of the study used Variant Analysis (ANOVA) and continued with the smallest real difference (BNT) test. The results showed that the administration of aloe vera extract (Aloe vera L.) could inhibit the growth of Colletotrichum capsici fungus at a maximum concentration of 100%. The higher the concentration of aloe vera extract, the higher its ability to inhibit the growth of Colletotrichum capsici fungus. The results of this study are feasible to be implemented in the form of  a digital flipbook as a learning medium with a feasibility of 83.2%.
