The Development of Teaching Materials on Digital Library "PUSDIGTI" to Improve Students Beginning Reading Abilities and Independent Character on 1st Grade Primary School

ABSTRAK

Penelitian ini bertujuan untuk mengembangkan dan menguji kelayakan bahan ajar berbasis perpustakaan digital PUSDIGTI dalam meningkatkan kemampuan membaca permulaan dan membentuk karakter mandiri siswa kelas 1 sekolah dasar. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan model ADDIE (Analysis, Design, Development, Implementation, Evaluation). Subjek penelitian adalah 51 siswa kelas 1 SDN Sidokare 3, Sidoarjo, pada semester ganjil tahun ajaran 2025/2026. Desain penelitian menggunakan one group pretest-posttest dengan instrumen berupa lembar validasi, angket respon guru dan siswa, serta tes membaca permulaan. Hasil penelitian menunjukkan bahwa: (1) Validitas bahan ajar memperoleh persentase rata-rata 96,4% dari hasil penilaian ahli materi, media, dan Bahasa dengan kategori sangat valid, sehingga layak digunakan dalam pembelajaran; (2) Kepraktisan memperoleh rata-rata 87,5% dari guru dan 84,6% dari siswa dengan kategori sangat praktis, menandakan bahan ajar mudah digunakan dan sesuai kebutuhan pembelajaran; (3) Keefektifan bahan ajar terbukti melalui peningkatan skor rata-rata pretest 26,10 menjadi 79,51 pada posttest dengan N-Gain rata-rata 0,70 (kategori tinggi). Uji Wilcoxon Signed Ranks Test menunjukkan perbedaan signifikan (sig. 0,000 < 0,05) antara hasil pretest dan posttest. Selain itu, observasi menunjukkan adanya peningkatan karakter mandiri siswa, khususnya dalam inisiatif, percaya diri, dan kemampuan menyelesaikan tugas secara mandiri. Kesimpulannya, bahan ajar berbasis perpustakaan digital PUSDIGTI dinyatakan valid, praktis, dan efektif untuk meningkatkan kemampuan membaca permulaan sekaligus menumbuhkan karakter mandiri siswa kelas 1 sekolah dasar. Penelitian ini memberikan kontribusi pada pengembangan media pembelajaran digital yang selaras dengan kebutuhan literasi awal di sekolah dasar.

ABSTRACT

This study aims to develop and test the feasibility of PUSDIGTI digital library-based teaching materials to improve the early reading skills and develop the independent character of first-grade elementary school students. The research method used was Research and Development (R&D) with the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model. The research subjects were 51 first-grade students of SDN Sidokare 3, Sidoarjo, in the odd semester of the 2025/2026 academic year. The research design used a one-group pretest-posttest approach with instruments in the form of a validation sheet, teacher and student response questionnaires, and an early reading test. The results showed that: (1) The validity of the teaching materials obtained an average percentage of 96.4% from the assessment of material, media, and language experts, placing it in the very valid category and making it suitable for use in learning; (2) The practicality obtained an average of 87.5% from teachers and 84.6% from students in the very practical category, indicating the teaching materials are easy to use and meet learning needs; (3) The effectiveness of the teaching materials was proven through an increase in the average pretest score from 26.10 to 79.51 in the posttest, with an average N-Gain of 0.70 (high category). The Wilcoxon Signed Ranks Test showed a significant difference (sig. 0.000 < 0.05) between the pretest and posttest results. Additionally, observations showed an increase in students' independent character, particularly in initiative, self-confidence, and the ability to complete tasks independently. In conclusion, the PUSDIGTI digital library-based teaching materials are declared valid, practical, and effective for improving early reading skills while fostering the independent character of first-grade elementary school students. This research contributes to the development of digital learning media that aligns with the early literacy needs in elementary schools.
