Penelitian ini dilatar belakangi oleh rendahnya literasi energi siswa dan kurangnya keterlibatan siswa dalam proyek autentik yang mengintegrasikan sains, teknologi, rekayasa, dan matematika. tujuan penelitian ini adalah untuk mengetahui kevalidan, kepraktisan dan efektivitas lkpd berbasis project based learning terintegrasi stem (pjbl-stem) dalam meningkatkan literasi energi siswa. jenis penelitian ini adalah penelitian dan pengembangan (research and development) dengan model addie (analysis, design, development, implementation, evaluation). subjek penelitian terdiri dari 30 siswa kelas x-3 sma negeri unggul binaan bener meriah. instrumen pengumpulan data meliputi lembar validasi ahli, angket respon guru dan siswa, tes serta angket literasi energi, dan lembar observasi. hasil penelitian menunjukkan bahwa lkpd yang dikembangkan dinyatakan valid dengan skor rata-rata ahli sebesar 3,13. produk dinilai praktis dengan respon sangat positif dari siswa (84,66) dan guru (94,44), serta persentase keterlaksanaan aktivitas guru mencapai 80% (kategori baik). lkpd dinyatakan efektif meningkatkan literasi energi siswa, di mana domain pengetahuan mengalami peningkatan dengan n-gain 0,65 (sedang), domain sikap meningkat dari skor 59,72 menjadi 85,18, dan domain perilaku meningkat dari 67,20 menjadi 81,33. rekomendasi penelitian ini adalah agar guru mengadopsi lkpd berbasis pjbl-stem dengan menyesuaikan konteks peserta didik dan kondisi sekolah. penelitian selanjutnya disarankan memperkuat domain pengetahuan melalui studi kasus sosio-saintifik

This study was motivated by students' low energy literacy and their lack of engagement in authentic projects integrating science, technology, engineering, and mathematics (STEM). The study aimed to determine the validity, practicality, and effectiveness of STEM-integrated Project-Based Learning (PjBL-STEM) student worksheets in enhancing students' energy literacy. It employed a Research and Development (R&D) approach using the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The subjects were 30 students from class X-3 at SMA Negeri Unggul Binaan Bener Meriah. Data collection instruments included expert validation sheets, teacher and student response questionnaires, energy literacy tests and questionnaires, and observation sheets. The results indicated that the developed worksheets were valid, with an average expert score of 3.13. The product was deemed practical, eliciting very positive responses from students (84.66) and teachers (94.44), while the implementation rate of teacher activities reached 80% (categorized as good). The worksheets proved effective in improving students' energy literacy: the knowledge domain showed an N-gain of 0.65 (medium), the attitude domain score rose from 59.72 to 85.18, and the behavior domain score increased from 67.20 to 81.33. It is recommended that teachers adopt these PjBL-STEM-based worksheets while adapting them to the students' context and school conditions. Future research is advised to further strengthen the knowledge domain through socio-scientific case studies.Keywords: LKPD, PjBL-STEM, Energy Literacy.
