Abstract

Ginger (Zingiber officinale) is the main biopharmaceutical export commodity of Indonesia. However, its productivity and quality are low because it is not cultivated using optimal techniques. This study aimed to examine the effect of magnesium (Mg) fertilizer on the growth, rhizome yield, and essential oil content of two ginger varieties in the organic field. The two factors tested were the rate of Mg fertilizer application (0, 50, 100, and 150 kg MgOha-1) and the variety of ginger (elephant ginger [Zingiber officinale var. officinarum] and red ginger [Zingiber officinale var. rubrum]). The variables measured were plant height, number of leaves, number of tillers, rhizome weight, and essential oil content. Mg fertilizer application rate and ginger variety significantly affected growth, yield, and essential oil content. No interaction effects were found between the two factors. Mg fertilizer applied at 150 kg MgOha-1 resulted in the highest rhizome yield and essential oil content, with an increase of 21.74% and 15.38%, respectively, compared to the control (0 kg MgOha-1). The yield of elephant ginger was 29.41% higher than that of red ginger, whereas the essential oil content of the red ginger was 16.67% higher than that of the elephant ginger.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian tepung daun salam (Syzygium polyanthum Walp) dalam ransum yang disuplementasi dengan larutan Effective Microorganisms-4 (EM-4) melalui air minum terhadap karkas itik bali jantan. Penelitian ini menggunakan rancangan acak kelompok (RAK) dengan tujuh perlakuan dan tiga kelompok. Perlakuannya adalah sebagai berikut ransum tanpa kotoran itik, sekam padi, daun salam dan tanpa larutan EM-4 (A), ransum mengandung kotoran itik (B), perlakuan B + daun salam (C), ransum mengandung sekam padi (D), perlakuan D + daun salam (E), ransum mengandung serbuk gergaji kayu (F), perlakuan F + daun salam (G), perlakuan B, C, D, E, F, dan G mendapatkan larutan EM-4. Setiap kelompok berisi tiga ekor itik. Variabel yang diamati bobot potong, bobot karkas, persentase karkas dan komposisi fisik karkas. Dari hasil penelitian ini dapat disimpulkan bahwa pemberian tepung daun salam dalam ransum yang disuplementasi larutan EM-4 melalui air minum dapat memperbaiki karkas itik bali jantan.
