Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan biaya pakan hijauan dan tenaga kerja terhadap nilai produksi ternak sapi di Kabupaten Bolaang Mongondow Selatan dan mengetahui efiensi ekonomi penggunaan hijauan pakan terhadap nilai produksi ternak sapi di Kabupaten Bolaang Mongondow Selatan. Penelitian dilakukan dengan menggunakan metode survey terhadap peternak sapi. Sampel wilayah dipilih secara purposive berdasarkan jumlah populasi ternak sapi terbanyak dan terpilih Kecamatan Pinolosian. Sampel desa dipilih secara purposive dengan kriteria jumlah populasi ternak sapi terbanyak yaitu desa Pinolosian. Selanjutnya dari populasi Peternak sapi yang berpengalaman minimal 2 tahun dipilih secara acak sebanyak 30 peternak. Analisis data menggunakan fungsi produksi Cobb–Douglas untuk melihat pengaruh biaya hijauan pakan dan factor produksi tenaga kerja terhadap nilai produksi ternak sapi. Selanjutnya analisis efisiensi ekonomi dengan membandingkan Nilai Produk Marginal (NPM) dengan Biaya Faktor Marginal (BFM) hijauan dan tenaga kerja. Penggunaan hijauan pakan dikatakan efisien jika memenuhi syarat NPM = BFM, jika NPM>BFM belum efisien dan NPM<BFM tidak efisien. Hasil penelitian menunjukkan rata-rata kenaikan nilai Produksi ternak sapi (NPM )yang dimilik ipeternak dalam setahun Rp.7.965.377 biaya factor marginal hijauan pakan sebesar Rp3.360.725 dan biaya faktor marginal tenaga kerja sebesar Rp. 1.894.885. Pakan hijauan memberikan pengaruh nyata terhadap nilai produksi ternak sapi dengan koefisien 0,688 (P <.05) sedangkan faktor tenaga kerja member pengaruh nyata terhadap nilai produksi ternak sapi dengan koefisien 0,127 (P<.05) Perbandingan nilai produk marginal dan biaya pakan hijauan sebesar1,630 yang berarti penggunaan pakan hijauan belum optimal. Penggunaan tenaga kerja pada usaha ternak sapi belum optimal dengan perbandingan nilai produk marginal dan biaya pakan sebesar 1,847. Hasil penelitian menunjukkan bahwa dari sisi pakan hijauan maka nilai produksi ternak sapi di Kabupaten Bolaang Mongondow Selatan masih dapat ditingkatkan karena penggunaan pakan hijauan belum optimal. Kata kunci: ternak sapi, hijauan pakan, optimal

Lamtoro, a legume tree plant with high protein content that has a wide range of environmental adaptation to dry stress, but relatively limited to acid stress. Mutation of lamtoro through 40 Gy gamma ray irradiation on callus culture produces lamtoro callus candidates adapted with pH 3.4. Aim of the study was to measure the morphological characteristics of adapted lamtoro cv Tarramba pH 3.4 that produced by 40Gy gamma ray irradiation based on differences of cytokinins in tissue culture. The study used complete randomized design with three treatments of different sources of cytokines i.e. kinetin, BAP and TDZ with 10 replications. The results showed that 0.5 ppm TDZ was the best treatment in callus diameter, and produced crumbly callus texture, but showed callus color response that tended to be light green.

The objectives of this study were to evaluate the West Timor savanna productive at different season. The location of this study is in the station of Lili field, Assessment Institute for Agricultural Technology Naibonat Kupang, with 40 hectare of savannah for pasture, held in one year. The data collected are botanical composition, production, feed intake in savannah and forage quality also the carrying capacity. The data analyzed descriptively. The amount of goat used for measurement of feed intake in savannah is 10 does. The result showed that the averages of forage fluctuation available is between 0.61-4,33 ton/hectare. The lowest point of production is happened in the edge of dry season (October) that is 0.61 ton/hectare. Then it increases in early of rainy (December) and reaches the highest point in the early of dry season (April). From this point, then it decreases and reach the lowest point in October, so, the forage production in nature was increases in December. The composition rate of CP is very varied, that is 2.71-9.48%. The composition of CP in nature grass has no significant difference with the composition in other locations of Timor, that is 2.26 % in the ends of dry season and become 8-10% in the rainy. Most of forage on the pasture is nature grass that is upper 90% and relative less of leguminous plants. The lack proportion of leguminous plants in nature savannah result in the less of forage quality, especially during the dry season there is no legume proportion and the quality of nature grass become very low.

Livestock development is part of the development of the agricultural sector which has strategic value in meeting the food, especially animal protein is increasing. Agricultural development today has changed from a predominantly supply of carbohydrate to impartial toward providing animal protein. It is also associated with increased per capita income of the people in Indonesia. Cattle is one of the largest providers of animal protein and are ruminants that consume forage such as grass, legume and also leaves from trees. Forage available in the field also depends on the season. The study was conducted in the village of Belanga, Susut, Bangli District, using 13 types of forage in the location. Preparation of rations based on a combination of food resource availability based on the nutritional needs of cattle so that productivity is maintained. The combination of local forage composition from November to April TDN and protein content reached 57.03% and 12.68%, while in May to October TDN and protein reached 57.03% and 12.67%.Key words: forages availability, forage composition, and bali cattle produktivity

Grasses are known as part of palm plantation ecology and has benefits as source of ruminant feed. Besides, it is believed to have ability as Carbon Storage. However, to what extent the grass can be capable as Carbon Storage and what are the species that can be best fitted as Carbon Storage are still questionable especially for those that are grown on plantation. Thus, investigation was carried out to identify tropical grasses grown under palm plantation coverage that can be functioned as Carbon Storage as well as to determine its nutrition contents. Due to having many traditional plantations, Pauh District of Sarolangon Jambi was opted as observation area. From there, samples were taken randomly from plots and sub-plots that were pre-created. Grass samples are grouped into three groups; leave, stem and root, and taken to laboratory for analysis. Among those that were observed, Panicum brevifolium, Axonopus compressus, Centotheca longilamina, Centotheca longilamina ohwi and Schleria sumatrensis were shown their capability as carbon storage. However, those are carbon storage capable have slightly different in carbon and nitrogen contents, Acid Detergent Fiber (ADF) and Neutral Detergent Fiber (NDF) analysis and almost the same in fiber fractions.
