Asystasia gangetica is a native plant that has the potential as a superior forage. The potential superiority of A. gangetica is not widely known by farmers in Bali. A study has been carried out with the aim to determine the growth and growth characteristics of A. gangetica as a forage. A completely randomized design with 5 levels of urea fertilizer treatment and 4 replications was carried out at Sesetan Denpasar research station. The results showed that the plant growth indicated by the variable number of branches, number of leaves, and shoot root ratio gave the highest yield on the level of urea fertilizer 50 kg ha-1. Variable characteristics of plant growth such as Leaf Area Ratio, Leaf stem ratio, and plant length, have the same tendency, although they do not show significant differences. Observing the growth and growth characteristics of plants, it can be concluded that the use of urea fertilizer as much as 50 kg ha-1 provides the best growth and application of urea fertilizer exceeding 50 kg ha-1 will adversely affect the growth of A. gangetica. Keywords: A. gangetica, urea, growth, growth characteristics

Nowadays, availability of forage for cattle and other animal protein resources getting less and less due to land changing functions. This will lead to increase in land price, decrease in animal productivities the will end on sustainability of the animal husbandry business. In Bali, farmers applied a Three Strata Forage System to provide forage along dry and rainy seasons. This study purpose was to find out forage production from four types but similar size of land (1 ha) which applied in that system, that were Type A (rectangle: 200 m x 50 m), Type B (L Form: 4 x (50 x 50 m), Type C (rectangle: 125 m x 80 m) and Type D (squares: 100 m x 100 m). This simulation showed that the forage production of the land was 14.533,805 ton DM/year for type A and B; 14.301,434 ton DM/year for Type C : and 14.276,171 ton/DM/year for Type D. It can be concluded that the land in similar size but differ in shape or type produce different quantity of forages. And addition forage production and carrying capacity were estimated below of recommended the three strata forage system. Keywords: Forages, production, three strata forage system

Indonesia merupakan negara kepulauan yang memiliki garis pantai yang panjang dan berpotensi apabila dikelola dengan baik seperti untuk penyediaan pakan ternak. Memelihara ternak merupakan alternatif diversifikasi usaha untuk meningkatkan taraf hidup nelayan pada saat tidak melaut. Tujuan penelitian untuk mengetahui produktivitas hijauan tanaman kerandang pada berbagai media tanah. Rancangan percobaan adalah split plot pola faktorial dengan faktor utama media tanam dan dosis pupuk limbah kopi. Perlakuan yang diuji adalah tanah, pasir kali dan pasir pantai, media tersebut diberi pupuk dengan dosis 0%, 5%, 10%, dan 15% yang diulang tiga kali. Parameter yang diamati produktivitas hijauan setiap 60 hari, pertumbuhan tanaman setiap minggu setelah panen. Hasil penelitian menunjukkan bahwa produktivitas hijauan berat kering tertinggi pada media pasir kali 25,9 gram per panen pada dosis pemupukan 15%, kemudian diikuti pada media tanah 18,8 gram/tanaman/panen pada dosis 10%. Produksi terendah pada media pasir pantai 16,6 gram/tanaman/panen pada dosis 5%. Rataan produksi hijauan yang diberikan pupuk dibandingkan dengan perlakuan kontrol (0%) meningkatkan produksi 92,99%. Produksi hijauan tiap panen terjadi penurunan setelah pemotongan ke empat, sedangkan pada media pasir pantai pada awal produksi hijauan tertinggi kemudian panen berikutnya menunurun sampai panen kelima. Hasil penelitian ini disimpulkan bahwa tanaman kerandang dapat ditingkatkan produktivitasnya dengan pemberian pupuk organik dan setelah empat kali pemanenan perlu pemberian pupuk untuk mendapatkan hasil stabil.
