Abstract

Penerapan Biogas kotoran ternak merupakan salah satu upaya mitigasi terhadap perubahan iklim. Di Bali saat in iterdapat 791 unit biogas dengan volume antara 3 sampai 11m3 perunit biogas. Pemerintah Provinsi Bali mengucurkan dana 10 milya rpertahun untuk mendorong pembangunan dan pemanfaatan biogas. Limbah biogas dikenal sebagai slurry yang selanjutnya dikelola sehingga menghasilkan bioslurry. Penelitian pemanfaatan pupuk bioslurry untuk meningkatkan karakteristik tumbuhdan produksi pasture campuran telah dilaksanakan pada lahan kering di Desa Sebudi Kabupaten Karangasem Provinsi Bali. Hasil penelitian menunjukkan bahwa terjadi peningkatan karakteristik tumbuh tanaman antara lain tinggi tanaman, luas daun spesifik, nisbah daun dengan batang tanaman, serta meningkatnya pemberian pupuk bioslury dapat meningkatkan produksi hijauan total rumput panikum atau paspalum yang ditanam bersama legume. Berat kering oven total hijauan rumput paspalum yang ditanam bersama rumput panikum dan legume Centrocema yang dipupuk dengan pupuk bioslurry yakni masing-masing sebesar 4,75 dan 4,36 tonha-1. Penggunaan pupuk organik akan menghasilkan kualitas hijauan yang semakin baik apabila diterapkan pada kombinasi penanaman rumput panikum, paspalum bersama leguminosa. Kata kunci: pasture campuran, pupuk bioslurry, produksi dan karakteristik tumbuh, lahan kering

Abstract

Sesuai amanat sustainable development goals (SDG’s) usaha peternakan wajib mengarusutamakan kaedah-kaedah pembangunan berkelanjutan yang ramah lingkungan. Peningkatan permintaan akan daging sapi harus diimbangi dengan peningkatan produktivitas sapi untuk memenuhi ketersediaan populasi dan kualitas daging sapi. Kualitas ternak sapi yang dihasilkan sangat tergantung kepada ketersediaan dan kualitas hijauan yang dimakan ternak. Ketersediaan berbagai limbah pertanian dan industri mendorong upaya pengolahan limbah menjadi pakan ternak ruminansia. Limbah yang diolah langsung diberikan kepada ternak ruminansia sebagai pakan alternatif. Limbah biasanya dapat megandung bahan berbahaya, zat anti nutrisi, dan memerlukan biaya yang lebih tinggi untuk mengolahnya. Untuk mengakomodasi kearifan budaya, memelihara harmonisasi spiritualitas bagi petani/peternak, dan menerapkan prinsip-prinsip animal welfare, selayaknya ternak ruminansia seperti sapi bali mendapatkan makanan yang baik yang berasal dari tanaman pakan ternak dengan kualitas yang baik. Dengan demikian limbah harus diolah menjadi pupuk yang berkualitas tinggi sehingga dapat menyediakan hijauan berkualitas bagi ternak sapi bali. Output yang berkualitas menuntut input yang berkualitas juga. Kata kunci: limbah, animal welfare, hijauan berkualitas

Abstract

Waste of Aloevera is one of the agriculture wastes which have highly potential for Bali cattle feed supplement, so that research in order to learn the effect of supplementation of Aloevera as High Quality Feed Supplement (HQFS) is needed. Twenty male Bali cattle were used in this experiment, which weight range between 191 – 232 kg. Feed for cattle consisted of rice straw, concentrate and feed supplement in form of Hight Quality Feed Supplement (HQFS) which mixed from sea grass and waste of aleovera. Randomized Block Design was applied in this experiment with 4 repetitions. Treatment A was ad lib of rice straw + 2 kg of concentrate, Treatment B was ad lib of rice straw + 2 kg of concentrate + 150 g HQFS, Treatment C was ad lib of rice straw + 2.5 kg of concentrate + 150 g HQFS, Treatment D was ad lib of rice straw + 3 kg of concentrate + 150 g HQFS and Treatment E was ad lib of rice straw + 3 kg of concentrate. Results of this experiment showed that supplementation of HQFS tended to decrease feed consumption and methan production, meanwhile supplementation of HQFS could increase diets efficiency and therefore increased the growth of cattle. HQFS supplementation gave more effective response at lower quality diets meanwhile in good quality diets gave no positive effect.

Abstract

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

Abstract

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
