Penelitian ini bertujuan untuk mengembangkan lembar kegiatan peserta didik (lkpd) berbasis sains technology engineering and mathematics (stem) pada materi virus. subjek dalam penelitian ini adalah ahli materi, ahli media, guru bidang studi kimia dan siswa kelas ix man 4 aceh timur. pengumpulan data dilakukan dengan instrumen berupa lembar penilaian validasi ahli materi, ahli media, penilaian guru dan tanggapan/respon siswa. analisis data menggunakan analisis deskriptif kuantitatif dan kualitatif. jenis penelitian dan pengembangan pada lkpd berbasis stem mengacu pada model addie yaitu melalui tahap analysis, development, desain, implementation, dan evaluation karena pada model ini setiap tahap dilakukan revisi hingga didapatkan produk lkpd yang lebih baik. bentuk pengembangan lkpd kimia berbasis stem dengan pengembangan pada aspek materi, media, dan respon peserta didik. kelayakan bahan ajar kimia stem yang dinilai oleh para ahli media termasuk dalam kriteria layak (80%) dan ahli substansi materi juga termasuk dalam kriteria layak (90%) dan respon peserta didik juga termasuk menarik (92%). dengan demikian dapat disimpulkan bahwa bahan ajar berbasis stem dapat digunakan dalam proses pembelajaran hidrokarbon untuk kelas ix di man 4 aceh timur.

This study aims to develop Student Activity Sheets (LKPD) based on Science, Technology, Engineering, and Mathematics (STEM) on Virus material. The subjects in this study were material experts, media experts, teachers of chemistry studies and class IX students of MAN 4 Aceh Timur. Data collection was carried out with instruments in the form of material expert validation assessment sheets, media experts, teacher assessments and student responses. Data analysis used quantitative and qualitative descriptive analysis. The type of research and development on STEM-based LKPD refers to the ADDIE model, namely through the Analysis, Development, Design, Implementation, and Evaluation stages because in this model each stage is revised until a better LKPD product is obtained. The form of developing STEM-based chemistry LKPD with development on aspects of material, media, and student responses. The feasibility of STEM chemistry teaching materials assessed by media experts was included in the appropriate criteria (80%) and material substance experts were also included in the appropriate criteria (90%) and the student responses were also interesting (92%). Thus, it can be concluded that STEM-based teaching materials can be used in the hydrocarbon learning process for class IX at MAN 4 Aceh Timur.
