Abstract

Pembelajaran biologi SMA memerlukan rujukan visual yang menghubungkan teori jaringan otot dengan preparat mikroskopis. Penelitian ini bertujuan mendeskripsikan karakteristik mikroskopis otot rangka, jantung, dan polos serta merumuskan strategi identifikasinya. Menggunakan pendekatan deskriptif kualitatif, pengamatan dilakukan pada preparat awetan mamalia menggunakan mikroskop cahaya pada perbesaran 100 x dan 400 x. Hasil pengamatan menunjukkan ciri khas masing-masing jaringan: otot rangka (nukleus perifer dan lurik), otot jantung (nukleus sentral dan diskus interkalaris), serta otot polos (sel berbentuk gelendong, nukleus sentral, tanpa lurik). Strategi identifikasi dirumuskan dalam tiga tahap: pengaturan pencahayaan/fokus, pengamatan bertahap dari rendah ke tinggi, dan verifikasi morfologi serentak. Penelitian ini menghasilkan acuan visual yang bermanfaat untuk pembelajaran, dengan saran pengujian lebih lanjut di kelas.
