Tujuan penelitian ini adalah untuk meningkatkan hasil belajar Biologi siswa keles VII A SMP Negeri 1 Prambanan tahun pelajaran 2019/ 2020 melalui model pembelajaran discovery learning. Penelitian tindakan kelas ini terdiri dari tiga siklus, setiap siklus terdiri tahapan perencanaan, pelaksanaan, observasi, dan refleksi. Subyek dalam penelitian ini adalah siswa kelas VII A SMP Negeri 1 Prambanan sebanyak 32 siswa. Teknik pengumpulan data yang digunakan yaitu tes untuk hasil belajar kognitif dan observasi untuk mengamati aktivitas belajar. Teknik analisis data yang digunakan adalah deskriptif komparatif. Pada penelitian ini indikator kinerjanya adalah 85% dan siswa dapat mencapai nilai KKM 70. Hasil penelitian menunjukkan bahwa setelah diterapkan model pembelajaran discovery learning persentase ketuntasan hasil belajar IPA biologi siswa meningkat. Pada siklus I sebanyak 65,62%, siklus II sebanyak 81,25% dan pada siklus III 93,75%. Sedangkan untuk persentase aktivitas belajar biologi siswa juga meningkat pada setiap siklus, pada siklus I sebesar 59,37%, pada siklus II sebesar 65,62% dan pada siklus III 81,25%. Berdasarkan hasil yang diperoleh, model pembelajaran discovery learning dapat meningkatkan aktifitas dan hasil belajar IPA biologi siswa kelas VII A SMP Negeri 1 Prambanan tahun pelajaran 2019/ 2020.

ABSTRACT The use of mobile devices with the Android operating system which are used as supporting media and supplements in improving learning outcomes combined with demonstration methods and discovery learning or demon-disco learning is needed to help students improve learning outcomes in hydroponic plant cultivation vocational competency subjects at SMK. Kristen Terang Bangsa, because the use of android-based applications can provide new experiences regarding the use of information and communication technology, as well as provide opportunities for students to be able to learn more independently. The concept chosen as a learning medium is to present material about understanding, introduction to parts, types, and quizzes containing questions about hydroponic cultivation of plants. This research uses the Research and Development (RnD) product development method, using 6 out of 10 research stages, namely potentials and problems, data collection, product design, design validation, design improvement, product testing. The result of this research is to produce learning media in the form of android-based applications. The validity value of the media expert is 2.6 which is declared feasible, while the validity value of the material expert is 3.6 which is declared feasible, and is able to increase the average value in the hydroponic plant cultivation vocational competency subject at the Terang Bangsa Christian Vocational School which Initially 67 (with 13 students who had not reached the KKM) to 80 (with 4 students who had not reached the KKM).
