Abstract


ABSTRAK. Pertumbuhan dan kualitas Aglaonema dipengaruhi oleh beberapa faktor di antaranya media tanam dan aktivitas hormonal. Penggunaan media tanaman alternatif selain pakis dan hormon seperti sitokinin penting untuk diketahui. Tujuan penelitian ialah untuk mengetahui pengaruh kombinasi tiga komposisi media tumbuh sebagai media alternatif serta pemberian sitokinin terhadap pertumbuhan dan kualitas  Aglaonema Fit Langsit. Penelitian dilakukan di Rumah Kaca Fakultas Pertanian Universitas Padjadjaran mulai Bulan Mei sampai dengan Agustus 2008. Komposisi media tanam yang digunakan yaitu arang sekam, cocopeat, dan zeolit dengan perbandingan (2:2:1), (3:2:1), (4:2:1), dan sebagai kontrol digunakan pakis, humus, pasir malang, dan cocopeat (2:1:1:1) yang dikombinasikan dengan pemberian sitokinin dengan konsentrasi 0, 50, dan 100 µl/l yang disemprotkan pada daun setiap 2 minggu sekali. Hasil percobaan menunjukkan bahwa kombinasi arang sekam, cocopeat, dan zeolit (3:2:1) disertai sitokinin 50 µl/l memberikan pengaruh yang lebih baik dibandingkan perlakuan lainnya dalam memperpanjang dan memperlebar ukuran daun, sehingga dapat meningkatkan kualitas tanaman Aglaonema menjadi lebih rimbun dan kompak karena semakin meningkatnya ukuran daun.

ABSTRACT. Mubarok, S, Salimah, A, Farida, Rochayat, Y,  and Setiati, Y 2012. The Effect of Growing Media Compositions and Cytokinin Concentrations on the Growth of Aglaonema. The growth and quality of Aglaonema is affected by several factors such as growing media and hormones. The using of alternative growing media and hormones such as cytokinin are urgently needed to be identified. The aim of experiment was to find out the effect of the combination of three growing media composition as an alternative growing medium with cytokinin on the growth and quality of Aglaonema Fit Langsit. This experiment was conducted in Greenhouse at the Faculty of Agriculture, Padjadjaran University from May to August 2008. The compositions of growing media consisted of the mix of carbonated rice hulls, cocopeat, and zeolite at three combinations (2:2:1, 3:2:1, and 4:2:1) and a control consisted of the mix of fern, humus, malang sands, and cocopeat (2:1:1:1). They were combined with cytokinins of 0, 50, and 100 µl/l. The results showed that the composition of carbonated rice hulls, cocopeat, and zeolite (3:2:1) combined with 50 µl/l cytokinin gave a better result than other treatments in increasing leaves length and leaves width, so it increases the quality of Aglaonema become more dense and compact due to by increasing the leaf size.
