Penelitian ini bertujuan untuk mengetahui kelayakan dan respon peserta didik terhadap lembar kerja peserta didik elektronik (e-lkpd) berbasis potensi lokal pada materi ekosistem. penelitian ini menggunakan model pengembangan addie (analysis, design, development, implementation, evaluation). subjek uji coba dalam penelitian ini yaitu siswa kelas x mia 1 sman 2 tarakan yang berjumlah 33 siswa. kelayakan e-lkpd dinilai berdasarkan hasil rata-rata penilaian ahli materi, ahli media, dan praktisi guru dengan presentase kelayakan sebesar 90,3% termasuk dalam kategori sangat layak. respon peserta didik diperoleh dari rata-rata penilaian respon peserta didik dalam uji skala besar dengan presentase 89,75% termasuk dalam kategori sangat menarik. berdasarkan hasil tersebut lembar kerja peserta didik elektronik (e-lkpd) materi ekosistem berbasis potensi lokal layak untuk digunakan dalam pembelajaran.

This research aimed to examine learner's feasibility and response to local potential based electronic learner's worksheet (e-lkpd) on ecosystem material. this research used addie (analysis, design, development, implementation, evaluation) development model. the research's experimental model was 33 students grade x mia 1 state senior high school 2 tarakan. e-lkpd feasibility was assessed based on average result of assessment by material experts, media experts, and practitioners/teachers with feasibility percentage 90.3y6, classified as very feasible. learner's response was obtained from average assessment on learners' response in a big scale test with percentage 89.7596, classified as very interesting. based on the result, local potential based electronic learners worksheet (e-lkpd) on ecosystem material was feasible for use in learning.
