PENGEMBANGAN BUKU PENGAYAAN INTERAKTIF MATA PELAJARAN BAHASA INDONESIA MATERI TEKS BIOGRAFI UNTUK SISWA SMA/MA KELAS X

Many of the enrichment books currently available are still not in line with the Merdeka Curriculum. This situation has become an obstacle to improving the effectiveness of Indonesian language learning, especially in the subject of biographical texts and the achievement of learning outcomes for 10th grade high school/MA students.
This study aims to describe the development and feasibility of supplementary textbooks. The research employs the Research and Development (R&D) method using the Reflective, Recursive Design and Development (R2D2) model. The development process consists of three stages: 1) define, 2) design and development, and 3) disseminate. The research results show that 1) the define stage involved needs analysis through literature review. 2) the design and development stage included planning and feasibility assessment of the product by language education lecturers, linguistics lecturers, Indonesian language teachers, and 10th-grade high school/madrasah students. The feasibility results of the supplementary book showed average scores: graphics 0.88 (very good), language 0.89 (very good), content 0.89 (very good), utilization 0.88 (very good), and features 0.89 (very good).
This means that the supplementary book developed is suitable for use as an additional learning resource in biography text instruction. With a supplementary book that aligns with students' needs and is supported by interactive features and media, it is hoped that the learning process for the Indonesian language subject will become more effective, engaging, and capable of enhancing students' understanding and learning outcomes regarding biography texts.
