Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh motivasi belajar dan kemampuan komunikasi terhadap hasil belajar siswa dalam pembelajaran berbasis proyek dengan pendekatan STEM (PJBL-STEM) pada topik “Rumah Impian Hemat Energi”. Penelitian menggunakan pendekatan mixed-method dengan desain sequential explanatory. Data kuantitatif dikumpulkan dari 83 siswa kelas IX melalui angket motivasi belajar dan kemampuan komunikasi, serta nilai hasil belajar proyek. Data kualitatif diperoleh dari observasi pembelajaran, analisis dokumen modul ajar, dan refleksi siswa. Hasil analisis regresi linier berganda menunjukkan bahwa motivasi belajar (sig. = 0,804) dan kemampuan komunikasi (sig. = 0,949) tidak berpengaruh signifikan terhadap hasil belajar PJBL-STEM. Temuan kualitatif mengungkap bahwa meskipun motivasi dan komunikasi siswa cukup baik, hasil belajar lebih dipengaruhi oleh faktor lain seperti kompleksitas proyek, scaffolding guru, dan keterampilan berpikir kritis. Implikasi penelitian ini menekankan perlunya pendekatan pembelajaran yang lebih terintegrasi dan holistik dalam implementasi PJBL-STEM.

Abstract

This study aims to describe the implementation of a STEM-based teaching module  Project Based Learning (PjBL) through a project to build a Mini Hydroelectric Power Plant (PLTAM) from used materials and to analyze students' learning experiences in science learning. The study used a qualitative descriptive approach with a descriptive study design conducted at SMPN 1 Cilengkrang. The research procedure included the stages of problem orientation, project planning, prototyping, testing, and reflection. Data collection was carried out through observation, interviews, documentation, and analysis of student projects. Data analysis was carried out using the interactive model of Miles, Huberman, and Saldaña which includes data reduction, data presentation, and conclusion drawing, and its validity was tested through triangulation of sources and techniques. The results showed that the implementation of the STEM-PjBL teaching module took place systematically through five project stages. Project activities encouraged active student involvement, collaborative work, and the integration of elements of science, technology, engineering, and mathematics. Students demonstrated a better understanding of the principles of converting water energy into electrical energy. The use of used materials increased students' creativity and environmental awareness. The questionnaire data showed a very positive response, with an average score above 4.2 and a percentage of agree/strongly agree reaching 83.3%-100%. The implementation of the STEM-PjBL teaching module through the hydropower project using recycled materials was able to create more contextual, meaningful, and student-centered science learning, and is worthy of being used as an innovative alternative in renewable energy learning in junior high schools.
