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.
