Abstract

This research is motivated by issues that indicate the students' activities  at Senior High School 2 Palembang in biology education are still below the minimum criteria. The purpose of this study is to promoting students' learning activities in the topic of ecosystems by implemented of Social Emotional Learning (SEL). Method of this research is Classroom Action Research (CAR) design involving planning, action, observation, and reflection cycles during 2 cycles. In this research, the sample consists of students from class X.7. The data collected included observations of students' learning activities and documentation. The observation of learning activities covers several aspects, including visual activities, oral activities, writing activities, and mental activities. The results showed a significant increase in the percentage of students' average learning activity scores, from 37.1875% before the implementation (Pre-cycle) of Social Emotional Learning to 53.90625% after the implementation of Cycle I of Social Emotional Learning, and further increased to 77.5% after the implementation of Cycle II of Social Emotional Learning. Based on the results, it can be concluded that the implementation of Social Emotional Learning has significant potential in improving students' learning activities in the ecosystem subject.

Abstract

Wood fungi, frequently identified as the cause of Wood Rot Disease, produce enzymes that break down key components of plant cell walls, such as cellulose and lignin, allowing the fungi to act as pathogens. This study aims to identify wood fungi present in oil palm plants in Banyuasin, South Sumatra, and to test their growth abilities on various types of wood and enzyme activites (ligninase, cellulase, and hemicellulase). The research methods consist of isolation using an exploration method, morphological identification, and enzyme activities tests (cellulase, hemicellulase, and ligninase). Wood fungus isolation used Potato Dextrose Agar (PDA) media. Fungal morphology was identified macroscopically and microscopically. The data obtained from fungal morphology observations, fungal growth on wood, and enzyme activity were analyzed descriptively. A total of 11 isolates were obtained. Isolates A6, A7, and A11 showed high enzymatic activity, particularly in breaking down lignin, cellulose, and hemicellulose, which potentially causes BPB in oil palms. The cellulase enzyme activity, measured with CMC substrate, indicated that isolate A6 had the highest value (157.30 U/mL), followed by A8 (151.75 U/mL), while A10 had the lowest value (20.58 U/mL). Using Avicel substrate to measure hemicellulase, isolate A10 showed the highest value (108.67 U/mL). For ligninase measured with tannin substrate, isolate A4 had the highest activity (59.89 U/mL), and A10 had the lowest (2.42 U/mL).
