Data analysis was performed using the Miles & Huberman analysis technique. The results of research on the implementation of blood-based biology learning at SMAN 06 Merangin show that (1) the lesson planning is carried out, namely: determining the application, recording conditions and student phone numbers, preparing online learning tools; (2) implementation of online learning, namely preliminary activities in the form of filling in attendance via Google Form, Google Classroom or Whatsapp and submitting learning objectives to Google Classroom or Whatsapp. The core activities are in the form of delivering material, question and answer sessions via Classroom or Whatsapp. Closing activities in the form of drawing conclusions and assignments; (3) evaluations of online learning, namely, assessment of knowledge seen from the results of assignments, discussion of questions, and online exams.

Begitu juga dengan SMAN 06 Merangin. Penelitian ini bertujuan untuk memperoleh gambaran pelaksanaan pembelajaran biologi secara daring di SMAN 06 Merangin. Subjek penelitian ini adalah guru biologi. Data dikumpulkan dengan wawancara. Analisis data dilakukan menggunakan teknik analisis Miles & Huberman. Hasil penelitian terhadap pelaksanaan pembelajaran biologi berbasis daring di SMAN 06 Merangin menunjukkan bahwa (1) Perencanaan pembelajaran yang dilakukan meliputi: menentukan aplikasi, pendataan kondisi dan nomor telepon siswa, menyiapkan perangkat pembelajaran daring; (2) pelaksanaan pembelajaran daring terdiri dari kegiatan pendahuluan berupa mengisi absensi melalui Google Form, Google Classroom  atau Whatsapp dan penyampaian tujuan pembelajaran pada Google Classroom atau Whatsapp. Kegiatan inti meliputi penyampaian materi, sesi tanya jawab melalui Classroom  atau Whatsapp. Kegiatan penutup berupa penarikan kesimpulan dan penugasan; (3) evaluasi pembelajaran daring meliputi, penilaian pengetahuan, keterampilan dan sikap.
