Penelitian ini bertujuan untuk mengetahui kelayakan booklet digital pada keanekaragaman belalang di hutan penelitian Universitas Borneo Tarakan sebagai bahan belajar di SMP Negeri 2 Tanjung Palas Utara. Jenis penelitian yang digunakan yaitu penelitian dan pengembangan dengan menggunakan prosedur penelitian Borg and Gall yang melalui lima tahap pengembangan (penelitian dan pengumpulan data, perencanaan, pengembangan produk awal, uji lapangan awal, dan revisi produk utama). Uji coba produk terbatas dilakukan di SMP Negeri 2 Tanjung Palas Utara pada kelas VII sebanyak 12 siswa. Instrumen pengumpulan data yang digunakan berupa lembar respons siswa dan lembar validasi. Data penelitian dianalisis melalui uji validasi produk dan respons siswa menggunakan kriteria penilaian skala likert. Uji validasi produk akan dilakukan oleh ahli materi, ahli media, dan praktisi guru.. Hasil pengembangan booklet digital keanekaragaman belalang memperoleh hasil validasi ahli materi 74% (baik), ahli media 69% (baik), praktisi guru IPA 80% (baik), dan respons siswa 91% (sangat baik). Berdasarkan hasil tersebut disimpulkan pengembangan booklet digital pada keanekaragaman belalang (ordo orthoptera) sebagai sumber belajar IPA yang telah dikembangkan memenuhi kriteria baik dan sangat baik sebagai sumber belajar siswa di SMP Negeri 2 Tanjung Palas Utara.

This study aims to determine the feasibility of using digital booklets on locust diversity as learning materials in the research forest of Borneo University Tarakan at SMP Negeri 2 Tanjung Palas Utara. The type of research used was research and development using Borg and Gall research procedures through five stages of development (research and data collection, planning, initial product development, initial field test, and main product revision). The limited product trial was conducted at SNIP Negeri 2 Tanjung Palas Utara in class VII with as many as 12 students. The data collection instruments used were student response sheets and validation sheets. Research data were analyzed through product validation tests and student responses using Likert scale assessment criteria. Material experts, media experts, and teacher practitioners will carry out product validation tests. The results of the development of digital booklets of grasshopper diversity obtained material expert validation results of 74% (good), media experts 69% (good), science teacher practitioners 80% (good), and student responses 91% (very good). Based on these results, it was concluded that developing digital booklets on locust diversity (order orthoptera) as a science learning material that has been developed meets the criteria of good and very good as a student learning resource at SNIP Negeri 2 Tanjung Palas Utara.
