The biology teacher of grade X has used an assessment based on the Independent Curriculum which consists of diagnostic, formative, and summative assessments. The conclusion of this study is that the implementation of the independent learning curriculum with a scientific approach on the material of environmental change and preservation in grade X of SMA Negeri 1 Batang Kuis for the 2024/2025 academic year at the planning stage is categorized as good, the overall implementation stage is categorized as good, and the assessment stage is categorized as good. Abstrak. Penelitian ini bertujuan untuk mengetahui implementasi kurikulum merdeka belajar dengan scientific approach pada materi perubahan dan pelestarian lingkungan hidup di kelas X SMA Negeri 1 Batang Kuis T.P 2024/2025. Desain penelitian yang digunakan yaitu deskriptif kuantitatif dengan metode survei. Teknik pengumpulan data penelitian ini dengan menggunakan lembar analisis modul ajar, lembar observasi, kuesioner peserta didik, dan tambahan berupa wawancara. Data dianalisis dengan menggunakan rumus persentase. Hasil penelitian menunjukkan bahwa perencanaan pembelajaran yang disusun guru memiliki kesesuaian dengan komponen kurikulum merdeka dengan kategori baik, dan menjabarkan langkah kegiatan scientific approach. Sementara implementasi kurikulum merdeka dengan scientific approach pada pembelajaran biologi dalam kategori baik, yang terdiri dari kegiatan awal dengan kategori baik, kegiatan inti dengan kategori baik, dan kegiatan akhir dengan kategori baik. Sedangkan penerapan Scientific Approach (5M) dalam kategori baik, meliputi tahapan mengamati dengan kategori baik, tahap menanya dalam kategori kurang, tahap mengumpulkan data dalam kategori cukup, tahap mengasosiasikan dalam kategori sangat baik, dan mengkomunikasikan dengan kategori sangat baik. Guru biologi kelas X telah menggunakan penilaian berdasarkan Kurikulum Merdeka yang terdiri dari asesmen diagnostik, formatif, dan sumatif dengan baik. Namun, guru jarang menggunakan rubrik penilaian sebagai pedoman dalam melakukan penilaian. Dapat disimpulkan bahwa implementasi kurikulum merdeka dengan Scientific Approach di kelas X SMA Negeri 1 Batang Kuis terlaksana dengan baik]]>
