Abstract

Penelitian ini bertujuan untuk mengembangkan, menguji kelayakan, dan menguji keefektifan bahan ajar e-book berbasis lingkungan pada muatan pembelajaran IPA Kelas IV SD Negeri 1 Mojowetan. Jenis penelitian ini Research and Development (R&D) yang diadaptasi oleh Sugiyono. Teknik pengumpulan data menggunakan teknik tes (pretest dan posttest) dan non tes (wawancara, observasi, dokumen). Hasil penelitian menunjukkan: (1) bahan ajar e-book berbasis lingkungan berbentuk elektronik memuat sampul, petunjuk penggunaan, KD, indikator, tujuan pembelajaran, materi gaya dan pengaruhnya terhadap gerak; (2) media ini sangat layak digunakan dengan bukti persentase oleh ahli materi 89% dan ahli media 100%; (3) berdasarkan uji t diperoleh nilai  (thitung> ttabel) sebesar (18,8414 > 2,023) sehingga disimpulkan bahan ajar e-book berbasis lingkungan efektif dan uji N-gain data pretest dan posttest diperoleh 0,66 dengan kategori sedang.
