Abstract

Zamioculcas zamiifolia ialah tanaman hias yang bernilai ekonomi tinggi pada umumnya diperbanyak secara vegetatif melalui stek daun. Keberhasilan perbanyakan stek dipengaruhi oleh media tanam dan zat pengatur tumbuh (ZPT). Penelitian ini bertujuan untuk mengetahui pengaruh berbagai media tanam dan aplikasi auksin sintetik serta ekstrak bawang merah terhadap respon morfologis stek daun Zamioculcas zamiifolia. Penelitian dilaksanakan menggunakan Rancangan Acak Lengkap (RAL) faktorial yang terdiri atas dua faktor. Faktor pertama adalah media tanam, yaitu tanah (M1), pasir (M2), sekam bakar (M3), dan lumut (M4), sedangkan faktor kedua adalah aplikasi ZPT, yaitu auksin sintetik (Z1) dan ekstrak bawang merah (Z2). Parameter yang diamati meliputi ukuran umbi, jumlah akar, dan panjang akar. Data dianalisis menggunakan analisis ragam (ANOVA), dilanjutkan dengan uji Duncan Multiple Range Test (DMRT) pada taraf 5% apabila terdapat pengaruh nyata.Hasil penelitian menunjukkan bahwa media tanam memberikan pengaruh yang lebih baik terhadap pertumbuhan morfologis stek daun dibandingkan aplikasi ZPT. Secara deskriptif, media lumut yang dikombinasikan dengan auksin sintetik (M4Z1) menghasilkan ukuran umbi, jumlah akar, dan panjang akar tertinggi dibandingkan perlakuan lainnya.

Morphological Response of Zamioculcas zamiifolia Leaf Cuttings to Various Growing Media with the Application of Plant Growth Regulator. First Supervisor: Ir. Dwie Retna Surjaningsih, M.P. Second Supervisor: Surya Ari Widya, S. Agr., M.P. ABSTRACT Zamioculcas zamiifolia is an ornamental plant with high economic value that is commonly propagated vegetatively through leaf cuttings. The success of cutting propagation is influenced by the growing medium and the application of plant growth regulators (PGRs). This study aimed to determine the effects of different growing media and the application of synthetic auxin and shallot (Allium cepa L.) extract on the morphological response of Zamioculcas zamiifolia leaf cuttings. The experiment was conducted using a factorial Completely Randomized Design (CRD) consisting of two factors. The first factor was the growing medium, namely soil (M1), sand (M2), rice husk charcoal (M3), and moss (M4). The second factor was the application of plant growth regulators, namely synthetic auxin (Z1) and shallot extract (Z2). The observed parameters included tuber size, root number, and root length. The data were analyzed using analysis of variance (ANOVA), followed by Duncan's Multiple Range Test (DMRT) at the 5% significance level when significant differences were detected. The results showed that the growing medium had a greater effect on the morphological growth of leaf cuttings than the application of plant growth regulators. Descriptively, the moss growing medium combined with synthetic auxin (M4Z1) produced the largest tuber size, the highest number of roots, and the greatest root length compared to the other treatments. Key word : Zamioculcas zamiifolia, leaf cuttings, growing media, plant growth regulators, synthetic auxin, shallot extract.
