<![CDATA[Kemampuan literasi numerasi siswa SMP masih rendah. Diperlukan media untuk memfasilitasi peningkatan literasi numerasi, misalnya dengan E-booklet berbasis matematika realistik. Penelitian ini bertujuan mendeskripsikan proses pengembangan dan validitas, serta kepraktisan efektivitas pengembangan E-Booklet berbasis matematika realistik terhadap kemampuan literasi matematis siswa. Model penelitian dan pengembangan dalam penelitian ini menggunakan model ADDIE (Analyze, Design, Development, Implementation, Evaluation). Penelitian dilakukan pada salah satu SMPN di Siliragung. Subjek penelitian dipilih dengan teknik purposive sampling. Data dikumpulkan melalui wawancara, kuesioner, dan tes. Analisis data menggunakan uji-t untuk mengetahui peningkatan kemampuan literasi matematis siswa. Hasil penelitian ini berupa e-booklet berbasis matematika realistik pada materi perbandingan dengan kriteria valid dengan rerata presentase validitas sebesar 93%. E-booklet ini dinyatakan praktis digunakan dalam proses pembelajaran dengan perolehan rerata kepraktisan sebesar 80% dan dinyatakan efektif dalam meningkatkan kemampuan literasi matematis siswa. E-booklet berbasis matematika realistik memenuhi kevalidan, kepraktisan dan keefektifan sehingga layak digunakan sebagai media pembelajaran. The numeracy literacy ability of junior high school students is still low. Media is needed to facilitate the improvement of numeracy literacy, for example with realistic mathematics-based E-booklets. This study aims to describe the development process and validity, as well as the practicality of the effectiveness of developing realistic mathematics-based E-Booklets on students' mathematical literacy abilities. The research and development model in this study uses the ADDIE model (Analyze, Design, Development, Implementation, Evaluation). The study was conducted at one of the junior high schools in Siliragung. The research subjects were selected using purposive sampling techniques. Data were collected through interviews, questionnaires, and tests. Data analysis used the t-test to determine the improvement of students' mathematical literacy abilities. The results of this study were in the form of realistic mathematics-based e-booklets on comparative material with valid criteria with an average validity percentage of 93%. This e-booklet was declared practical to use in the learning process with an average practicality of 80% and was declared effective in improving students' mathematical literacy abilities. Realistic mathematics-based e-booklets meet validity, practicality and effectiveness so they are suitable for use as learning media.]]>
