STEM-Based Learning in the Utilization of Ketapang Waste as an Alternative Energy Source and Processed Food in Science Subject Class 9 State of Junior High School 3 Blitar

Abstract

STEM Learning is a concrete step toward preparing the next generation of leaders. This is because there are structured and systematic steps in STEM learning that lead students to problem-solving, implementing innovations and strategies, learning to be self-reliant and independent, learning how to live in teamwork that requires collaboration, and providing opportunities for educators to apply methodologies, approaches, models, and learning media that value and trigger student learning. The assumption is that learning is no longer teacher-centered, but rather student-centered so that students are more engaged in the process.February-August for the 2021/2022 school year, the one group design quasi-experimental study method was used at State of Junior High School 3 Blitar. The population in this study was class 9A, which was chosen by purposeful sampling as the experimental class. The average is calculated using the N-Gain test. This demonstrates a shift in learning outcomes. The results of several tests are used to demonstrate the usefulness of learning media advances. The obtained values were t-count = -5.781, t-table = 0.05, and df = 29 is = 2.05. The mean value of the pre-test data and the average post-test data were substantially different because of the t-count (-5.781) t-table (-2.05). This difference indicates that the media used greatly affects student learning outcomes.
