Abstract

This study aimed to develop Powtoon animated videos for STEM-integrated physics learning and assess their impact on student learning outcomes. The Research and Development (R&D) method, using the ADDIE model, was employed to systematically develop and evaluate the instructional media. The study involved five phases: analysis, design, development, implementation, and evaluation. During the analysis phase, needs were identified based on observations of students' difficulties in understanding abstract physics concepts and their disengagement from traditional teaching methods. The videos were developed to integrate scientific, technological, engineering, and mathematical (STEM) concepts, focusing on simple machines such as levers and pulleys. Expert validation was conducted to assess the quality of the videos, and revisions were made accordingly. The implementation phase involved a pretest-posttest control group design with eighth-grade students from SMP Negeri 2 Watumalang. The experimental group used the STEM-integrated Powtoon videos, while the control group received traditional instruction. Data were analyzed using a t-test and N-Gain to measure the improvement in student learning outcomes. Results showed a significant improvement in the experimental group’s post-test scores, with an average N-Gain of 66.95%, categorized as moderately effective. The control group had a lower average N-Gain of 49.22%, categorized as less effective. The findings demonstrate that the Powtoon videos not only enhanced students' conceptual understanding but also increased their motivation and engagement in physics learning. These results suggest that integrating STEM principles into instructional media, such as animated videos, is an effective strategy for improving learning outcomes in physics. The study recommends expanding the use of such multimedia approaches across other STEM-related subjects to foster critical thinking and problem-solving skills in students.

Abstract

Sampah plastik setiap hari meningkat seiring dengan kebutuhan serta penggunaan manusia. Penimbunan sampah plastik menjadi masalah yang dihadapi oleh masyarakat karena plastik tidak mudah diuraikan dan mengandung zat kimia sehingga menyebabkan pencemaran lingkungan. Penelitian ini bertujuan untuk mengetahui pengelolaan sampah di Wonosobo. Penelitian dilakukan di Desa Siwuran Kecamatan Garung Kabupaten Wonosobo, Jawa Tengah dengan menggunakan metode observasi dan wawancara. Pengumpulan data dari wawancara pemilik dan karyawan pengelolaan barang bekas dan observasi di lapangan untuk dianalisis secara sistematis. Hasil penelitian menunjukkan bahwa pengelolaan sampah di Desa Siwuran, Garung menggunakan metode 3R yaitu reduce atau mengurangi sampah plastik yang ada di daerah Wonosobo. hal ini dilakukan dengan cara menghancurkan sampah plastik menjadi serpihan plastik yang dijual ke pabrik Jakarta untuk dijadikan bahan baku ember (Recycle) dan dari hasil ember daur ulang tersebut dapat diperjualbelikan kembali kepada masyarakat untuk digunakan sesuai dengan kebutuhannya.
