Pengembangan Bahan Ajar Ekonomi Menggunakan Unity 3D dalam Bentuk Buku Saku Digital Berbasis Problem Based Learning

Bahan ajar merupakan sumber daya pendidikan untuk mentransfer pengetahuan, namun ketidakefektifan bahan ajar dapat menjadi penghambat dalam mencapai tujuan pembelajaran. Penelitian pengembangan buku saku digital berbasis Problem Based Learning (PBL) bertujuan untuk menjelaskan tingkat kelayakan; menganalisis efektivitas melalui hasil pembelajaran; serta mengetahui kepraktisan menggunakan buku saku digital dalam proses pembelajaran. Jenis penelitian adalah R&D (Penelitian dan Pengembangan) menggunakan model ADDIE oleh Dick & Carry. Prosedur penelitian terdiri dari lima tahap, analisis, desain, pengembangan, implementasi, dan evaluasi. Subjek penelitian adalah 20 siswa kelas XI IPA. Teknik pengumpulan data melalui wawancara, kuesioner, dan tes. Teknik analisis data melalui (1) analisis dan validasi ahli; (2) tanggapan kuesioner siswa; dan (3) perhitungan gain score. Hasil penelitian menunjukkan bahwa buku saku digital "sangat layak" digunakan dengan mendapatkan persentase skor kelayakan 83,77% dan kepraktisan 88%, serta mendapatkan gain score  0,64 dengan kriteria "sedang". Berdasarkan hasil ini, buku saku digital berbasis PBL dinyatakan sangat layak dan praktis untuk digunakan selama proses pembelajaran karena dapat meningkatkan hasil belajar.

Teaching materials are educational resources for transferring knowledge, but the ineffectiveness of teaching materials can be an inhibitors in achieving the learning objectives. The research on development digital pocket books based on Problem Based Learning (PBL) aimed to explain the level of feasibility; analyzed effectiveness through learning outcomes; as well as knowing the practicality of using digital pocket books in the learning process. Type of the research was a R&D (Research and Development) used the ADDIE model by Dick & Carry. The research procedure consisted of five stages, analysis, design, development, implementation, and evaluation. The research subjects were 20 students of class XI Science. Data collection techniques through interviews, questionnaires, and tests. Data analysis techniques are (1) expert analysis and validation; (2) student questionnaire responses; and (3) gain score calculation. The results showed that the digital pocket book "very feasible" was used by getting a percentage score of eligibility of 83.77% and practicality of 88%, as well as getting a gain score of 0.64 with the criteria of "moderate". Based on these results, PBL-based digital pocket books are declared very feasible and practical to use during the learning process because it can increase the learning outcomes.
