PENGEMBANGAN MEDIA PEMBELAJARAN INTERAKTIF BERBASIS STEM MATERI ENERGI TERBARUKAN – PLTB UNTUK MELATIHKAN KETERAMPILAN KOLABORASI SISWA SMA
This study aims to develop an interactive STEM-based learning media on renewable energy, specifically Wind Power Plants (PLTB), to foster collaboration skills among high school students. The development model employed is ADDIE (Analysis, Design, Development, Implementation, Evaluation). Needs analysis revealed that most students possess digital devices, have adequate internet access, and show high interest in STEM approaches. The media was developed using Articulate Storyline 3, integrating text, images, videos, PLTB simulations, and collaborative projects. Expert validation results indicated a validity score of 93.48% (very valid), confirming that the media meets the feasibility criteria in terms of content accuracy, visual design, language use, and alignment with high school physics learning. Individual trials (one-to-one) achieved a practicality score of 94.34% (very practical), while small group trials reached 89.47% (very practical), demonstrating that the media is easy to use, visually engaging, and supportive of collaborative learning activities. The effectiveness of the media was also high, as shown by the improvement in learning outcomes from an average pre-test score of 74 to a post-test score of 92.33, with an N-Gain of 0.73 (high category). Furthermore, students’ collaboration skills increased from 84.6% to 88.9% (a 4.3% improvement). These findings confirm that the interactive STEM-based learning media on PLTB is not only effective in enhancing learning outcomes but also strengthens collaboration skills, particularly responsibility, compromise, and respect for ideas, as part of 21st-century skills.
