Relevant teaching materials according to achievement competence can support the learning process well so that learning objectives can be achieved. Digital textbooks with a spatial approach create effective learning activities. The use of maps and pictures in teaching materials with a spatial approach will attract more students' interest. The purpose of this research is to produce a digital Geography textbook with a spatial approach to the earth's material as living space. The research procedure uses the Borg and Gall model with seven paths, namely needs analysis, planning, product draft development, product validation, initial product revision, product testing, and final product refinement. The test subjects were students of class XI SMA Negeri 4 Blitar. Development research instrument in the form of a Likert scale questionnaire. Data analysis techniques with quantitative descriptive obtained from the results of filling out the questionnaire. The results of the feasibility test by the material validator were 78.3 percent (enough), the media validator was 100 percent (very feasible), the language validator was 89.6 percent (very feasible). The test results on students obtained a percentage of 89.6 percent (very decent) and teachers got a percentage of 87.4 percent (very decent). Thus, digital textbooks are declared very feasible to be implemented in Geography learning activities. Bahan ajar yang relevan sesuai kompetensi pencapaian dapat mendukung proses pembelajaran dengan baik sehingga tujuan pembelajaran bisa tercapai. Buku ajar digital dengan pendekatan spasial menciptakan kegiatan pembelajaran yang efektif. Penggunaan peta dan gambar dalam bahan ajar dengan pendekatan spasial akan lebih menarik bagi siswa. Tujuan penelitian ini untuk menghasilkan buku ajar Geografi digital dengan pendekatan spasial materi Bumi sebagai ruang kehidupan. Prosedur penelitian menggunakan model Borg dan Gall dengan tujuh alur yaitu analisis kebutuhan, perencanaan, pengembangan draf produk, validasi produk, revisi produk awal, uji coba produk, dan penyempurnaan produk akhir. Subjek uji coba siswa kelas XI SMA Negeri 4 Blitar. Instrumen penelitian pengembangan berupa angket skala likert. Teknik analisis data dengan deskriptif kuantitatif diperoleh dari hasil pengisian angket. Hasil uji kelayakan oleh validator materi 78,3 persen (layak), validator media 100 persen (sangat layak), validator bahasa 89,6 persen (sangat layak). Hasil uji coba terhadap siswa memperoleh persentase 89,6 persen (sangat layak) dan guru memperoleh persentase 87,4 persen (sangat layak). Dengan demikian buku ajar digital dinyatakan sangat layak diimplementasikan dalam kegiatan pembelajaran Geografi. |
