Dalam pembelajaran kimia dibutuhkan upaya untuk memperbaiki proses pembelajaran demi meningkatkan kemandirian dan kualitas hasil belajar peserta didik. Penelitian ini bertujuan untuk mengetahui tingkat kemandirian belajar dan kualitas hasil belajar peserta didik setelah penerapan model pembelajaran Blended Learning pada materi konsep mol. Penelitian studi quasi eksperimen ini menerapkan dua desain penelitian The One-Group Pretest-Posstest untuk kemandirian belajar dan The One-Group Posstest-Only untuk hasil belajar peserta didik. Populasi penelitian adalah seluruh siswa kelas X IPA 1 di SMAN 1 Gunung Meriah dengan mengambil subjek penelitian satu kelas eksperimen tanpa kelas kontrol atau kelas pembanding melalui teknik purposive sampling berdasarkan ciri-ciri tertentu yang sesuai dengan tujuan penelitian. Pengumpulan data dilakukan dengan menggunakan dua macam instrumen yaitu tes dan non-tes. Tes meliputi tes pemahaman materi konsep mol dan non-tes meliputi angket kemandirian belajar peserta didik. Untuk melihat adanya peningkatan kemandirian dan mengetahui kualitas hasil belajar peserta didik setelah penerapan model pembelajaran Blended Learning pada materi konsep mol digunakan uji persen dan uji N-gain. Berdasarkan hasil penelitian, diketahui bahwa kemandirian belajar peserta didik setelah penerapan model pembelajaran Blended Learning pada materi konsep mol lebih baik daripada sebelum penerapan model pembelajaran Blended Learning, meningkat sebesar 74,34% dengan kategori baik dari sebelumnya hanya sebesar 68,11% dengan kategori cukup, dilihat dari hasil analisis N-Gain termasuk kategori rendah. Persentase ketuntasan hasil belajar berdasarkan data postest peserta didik diperoleh sebesar 82,75% dengan kategori sangat tinggi. Hasil belajar peserta didik setelah penerapan model pembelajaran Blended Learning pada materi konsep mol diperoleh persentase sebesar 83,53% dengan kategori baik, dengan persentase perolehan nilai akhir yaitu 62,06% dari 29 siswa termasuk kategori baik, dan 37,93% dari 29 siswa termasuk kategori sangat baik.

In chemistry learning, efforts are needed to improve the learning process in order to increase the independence and quality of student learning outcomes. This study aims to determine the level of learning independence and the quality of student learning outcomes after the application of the Blended Learning learning model to the mole concept material. This quasi-experimental study applies two research designs, The One-Group Pretest-Posstest for independent learning and The One-Group Posttest-Only for student learning outcomes. The research population was all students of class X IPA 1 at SMAN 1 Gunung Meriah by taking the research subject of one experimental class without a control class or comparison class through purposive sampling technique based on certain characteristics according to the research objectives. Data was collected using two kinds of instruments, namely test and non-test. The test includes a test of understanding the mole concept material and non-test includes a student learning independence questionnaire. To see an increase in independence and determine the quality of student learning outcomes after the application of the Blended Learning learning model to the mole concept material, the percent test and the N-gain test were used. Based on the results of the study, it is known that the learning independence of students after the application of the Blended Learning learning model on the mole concept material is better than before the application of the Blended Learning learning model, increasing by 74.34% in the good category from the previous only 68.11% in the moderate category. , seen from the results of the analysis of N-Gain is in the low category. The percentage of complete learning outcomes based on student posttest data was obtained at 82.75% with a very high category. Student learning outcomes after the application of the Blended Learning learning model to the mole concept material obtained a percentage of 83.53% in the good category, with the percentage of final score acquisition being 62.06% of 29 students in the good category, and 37.93% of 29 students included in the very good category.
