<![CDATA[The learning process in secondary schools is still often confronted with constraints due to the dominance of lecture methods and conventional textbooks, which make students tend to be passive in learning. This development research aims to produce Student Learning Activities Guide (SLAG) teaching materials for Grade VII students at SMP Kalam Kudus Sorong City that are valid, effective, and engaging. The development procedure adapted the Borg and Gall model modified by Sugiyono into nine main stages, including potential and problem analysis, data collection, product design, design validation, design revision, product testing, product revision, main testing, and final revision. Data collection instruments consisted of interview sheets, questionnaires, learning achievement tests, and observation sheets. Data analysis techniques utilized qualitative descriptive analysis and quantitative descriptive statistics. The results showed that the SLAG teaching material obtained a validity percentage of 93.98% (very valid), an effectiveness percentage of 91.85% (very effective) with 100% classical completeness, and an attractiveness percentage of 91.02% (very attractive). In conclusion, SLAG teaching materials are highly feasible and effective for improving student activity and learning outcomes at SMP Kalam Kudus Sorong City. ABSTRAK Proses pembelajaran di sekolah menengah masih sering dihadapkan pada kendala dominasi metode ceramah dan penggunaan buku teks konvensional yang membuat siswa cenderung pasif dalam belajar. Penelitian pengembangan ini bertujuan untuk menghasilkan bahan ajar Student Learning Activities Guide (SLAG) untuk siswa kelas VII SMP Kalam Kudus Kota Sorong yang valid, efektif, dan menarik. Prosedur pengembangan mengadaptasi model Borg dan Gall yang dimodifikasi Sugiyono hingga sembilan tahapan utama, meliputi analisis potensi dan masalah, pengumpulan data, desain produk, validasi desain, revisi desain, uji coba produk, revisi produk, uji coba pemakaian, dan revisi akhir. Instrumen pengumpulan data terdiri atas lembar wawancara, angket, tes hasil belajar, dan observasi. Teknik analisis data menggunakan analisis deskriptif kualitatif dan statistik deskriptif kuantitatif. Hasil penelitian menunjukkan bahwa bahan ajar SLAG memperoleh persentase kevalidan sebesar 93,98% (sangat valid), persentase keefektifan sebesar 91,85% (sangat efektif) dengan ketuntasan klasikal 100%, serta persentase kemenarikan sebesar 91,02% (sangat menarik). Kesimpulannya, bahan ajar SLAG sangat layak dan efektif digunakan untuk meningkatkan keaktifan serta hasil belajar siswa dalam pembelajaran di SMP Kalam Kudus Kota Sorong. ]]>
