Abstract

Mitosis cell division is an important process in plant growth and occurs actively in meristematic tissues, one of which is the root tip of shallots (Allium cepa). Mitotic activity can be influenced by the growing medium used, especially media containing nutrients and growth regulators. This study aimed to examine the process of mitotic cell division in shallot root tips soaked in three different media, namely plain water, rice washing water, and young coconut water. The research was conducted using an experimental method with a descriptive approach. Shallots were soaked for approximately 48 hours until roots were formed, then the root tips were prepared using the squash method and observed under a light microscope. The observed parameters included the stages of mitosis and root growth. The results showed that the plain water medium only exhibited prophase and telophase stages with low mitotic activity. The rice washing water medium showed telophase and cytokinesis stages with moderate mitotic activity. Meanwhile, the young coconut water medium exhibited more complete mitotic stages, namely prophase, telophase, and cytokinesis, and produced the most optimal root growth. These findings indicate that the type of soaking medium affects mitotic activity in shallot roots, with young coconut water being the most effective medium in supporting cell division.

Abstract

Keanekaragaman tumbuhan berbunga di kawasan Universitas Negeri Medan (UNIMED) cukup tinggi dan memiliki peranan penting bagi lingkungan kampus maupun sebagai sumber belajar mahasiswa. Namun, kajian mengenai identifikasi tumbuhan famili Malvaceae dan Orchidaceae di kawasan UNIMED masih terbatas sehingga penelitian ini dilakukan untuk mengetahui jenis-jenis tumbuhan dari kedua famili tersebut beserta karakteristik morfologinya. Penelitian ini bertujuan untuk menganalisis keanekaragaman spesies tumbuhan famili Malvaceae dan Orchidaceae yang terdapat di lingkungan Universitas Negeri Medan. Metode penelitian yang digunakan adalah metode deskriptif kualitatif melalui observasi langsung dan dokumentasi. Identifikasi tumbuhan dilakukan berdasarkan ciri morfologi dengan bantuan aplikasi PlantNet dan referensi pendukung lainnya. Hasil penelitian menunjukkan bahwa ditemukan tiga spesies dari famili Malvaceae yaitu Hibiscus rosa-sinensis, Sida rhombifolia, dan Durio zibethinus, serta tiga spesies dari famili Orchidaceae yaitu Arachnis flos-aeris, Dendrobium crumenatum, dan Vanda Douglas. Setiap spesies memiliki ciri morfologi dan habitat yang berbeda sesuai dengan karakteristik familinya masing-masing. Keberadaan tumbuhan tersebut menunjukkan bahwa kawasan UNIMED memiliki keanekaragaman tumbuhan berbunga yang cukup baik dan berpotensi sebagai media pembelajaran botani serta pelestarian lingkungan kampus. Penelitian selanjutnya diharapkan dapat mengkaji lebih banyak famili tumbuhan dengan wilayah pengamatan yang lebih luas agar data keanekaragaman tumbuhan di kawasan kampus semakin lengkap.
