Climate change that has hit the world requires to make adaptation efforts so that agricultural productivity can be maintained. Alysicarpus vaginalis is one of the local variety forage that can grow in a various of environmental conditions. In this regard, a survey research has been carried out to study various types of local forages throughout Bali. The aim of the research is to obtain forages that have superior properties and can be developed in various regions in Bali. The survey sampling location refers to a map prepared specifically for that by overlaying a map of soil types, land use maps, and climate maps. Based on the results of the survey, several species of local forages that have superior characteristics have been found. One of them is Alysicarpus vaginalis plant as a forage superior, Alysicarpus vaginalis forage production as much as 46,302 kg DM ha-1 with 0.21% botanical composition. Keywords: Alysicarpus vaginalis, superior legumes, tropical forage

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

Provision of animal feed in accordance with quality standards and adequate quantities has become a strategic need to increase livestock productivity and accelerate the availability and fulfillment of foodstuffs from livestock. In this regard, a survey research has been designed to study some of the local fodder plants that have superior potential as animal feed. Fodder plants are classified as superior feed varieties if they have properties: easy to breed, high productivity as a producer of forage and / or seeds, has a fast regrowth, is resistant to defoliation, resistant to grazing, resistant to environmental stresses, and palatable for livestock. Based on the results of the survey, several species of local animal feed plants that have superior characteristics have been found. One of them is a phasey bean plant (Macroptilium lathyroides (L.) Urb.). Phasey bean as a superior animal feed plant (TPT) besides being suitable for the above characteristics also has grown naturally in an area in Bali so it needs to be tested for its feasibility to be distributed throughout Bali. Keywords: phasey bean, superior legumes, tropical forage

PERAN PEPOHONAN DALAM PENINGKATAN PRODUKSI TERNAK RUMINANSIA: PENDEKATAN ILMIAH I.M Mastika; A.W. Puger; I.K.M. Budiasa; M. Nuriyasa

Trees and shrubs plantation are very potential and important in producing sustainable green biomass, and have high protein content and high digestibility. Some of them are legume which are important in catching nitrogen from the air to enriched the soil nitrogen. Trees are also catching more sun energy radiation which is latter converted into animal feeds. Other roles of this plant is part of them such as leaves, fruits, barks and roots containing saponin/sapogenin or tannin which are useful as defaunating agent. It was well documented that rumen protozoa reduced ruminant productivity. From the reports available either in vitro or in vivo it was proved that saponin could to some extent reduced or depressed protozoa rumen population. Indonesia needs some experts effort to identify and recording those plants that could play roles as natural defaunating agent, as well as provide green biomass for ruminant. The overall conditions above will provide an ample opportunities for research for students or experties.

ABSTRACT Optimizing Integrated Farming System to Maximize Farmers’ Income This study aims to find out the optimal model of integrated farming system (SIMANTRI) development in farmers’ group of SIMANTRI 074, Jemberana Regency. Primary data by using survey method collected from 20 farmers of the group and secondary data gathered from any sources were used to specify parameters of the model. Linear programming analysis by using software BLPX88 is to solve constrained optimization problem in the model. A small farmer, which his farm size is 0.48 hectare, was optimal in allocating resources to conduct many farm activities under the SIMANTRI indicated byfrom optimal solution of the model which conforms to observed behavior. The maximum farmers’ income, generated from the optimizing process was Rp26,041,250 per annum. Key words: optimization, integrated farming system, income

Penelitian yang bertujuan untuk mengetahui pertumbuhan dan hasil hijauan Asystasia gangetica (L.) subsp. Micrantha yang dipupuk dengan limbah rumah potong hewan (RPH) terfermentasi, telah dilakukan di rumah kaca, Stasiun Penelitian Sesetan, Fakultas Peternakan, Universitas Udayana di Jalan Raya Sesetan Gang Markisa selama 8 minggu. Penelitian menggunakan rancangan acak lengkap (RAL) dengan empat perlakuan dan tujuh ulangan sehingga terdapat 28 unit percobaan. Perlakuan yang diberikan adalah dosis pupuk limbah rumah potong hewan terfermentasi yang terdiri atas : 0 ton ha-1, 10 ton ha-1, 20 ton ha-1 dan 30 ton ha-1. Variabel yang diamati yaitu variabel pertumbuhan, variabel hasil daan variabel karakteristik tumbuh. Hasil penelitian menunjukan bahwa pupuk limbah rumah potong hewan terfermentasi belum mampu meningkatkan pada variabel pertumbuhan, variabel hasil dan variabel karakteristik tumbuh. Perlakuan dosis 20 ton ha-1 pada tinggi tanaman menunjukan rataan paling tinggi sebesar 48,24 cm, perlakuan dosis 30 ton ha-1 pada berat kering total hijauan menunjukan rataan paling tinggi sebesar 4,89 g, dan perlakuan dosis 30 ton/ha pada nisbah berat kering total hijauan dengan berat kering akar menunjukan rataan paling tinggi sebesar 2,80 g. Disimpulkan bahwa pemberian limbah rumah potong hewan terfermentasi sebagai pupuk organik belum mampu meningkatkan pertumbuhan dan hasil tanaman Asystasia gangetica (L.) subsp. Micrantha. Kata kunci: limbah, fermentasi, Asystasia gangetica (L.) subsp. Micrantha, dosis, pupuk, pertumbuhan
