Judul: Potential Area Producing Feed Supporting the Development of Cattle Population in Tanah Laut Regency
Abstrak: Forage has very important role as a ruminant feed that can not be replaced by the concentrate. Almost 90% of ruminant ratio comes from forage. There is a continuing conversion of forage producing areas into other uses resulting in the reduction of forage availability 30 %. Remote Sensing (RS) technology and Geographical Information System (GIS) can be used in agricultural mapping to manage natural resources in certain. This study aimed to identify the potential of areas producing feed and determine its availability in supporting the development of cattle population in Tanah Laut Regency. The showed 72,902 ha of the area including pasture (6,324 ha) maize field (25,622 ha), paddy field (40,956 ha) has potential to produce forage of 234,404 tons dry matter per year. One sub district in the regency was classified as moderate CCI area. The RS technology and GIS can be used to calculate feed availability development of cattle population. Tanah Laut regency has a potential capacity to accommodate more cattle population.

Judul: Potensi Pengembangan Sapi Potong di Kabupaten Sijunjung Propinsi Sumatera Barat
Abstrak: Agricultural land in Sijunjung District that has not been optimally utilized could be used for the development of beef cattle farm. The development should conform land suitability as a reference to determine beef cattle development to achieve the government's target of meat self-sufficiency in 2010. This study aims to foresee the potential of land in Sijunjung District for development of beef cattle using a combined 2006 Landsat images, LREP maps and other supporting data through, financial analysis, and the desired rearing cattle the local community. The results indicate that the potential lands for the development were about 120,063 ha or 38.35% of the existing land area, which consists of mixed garden (100,359 ha), 3,247 ha of abandoned land, 11,027 ha of paddy fields and 5,428 ha of bush. Actualy, land carrying capacity is 55,518 Animal Unit, and the potential carrying capacity is 134,722 Animal Unit. The results of the NPV analysis for all farming schemes were positive, with B/C Ratio> 1, and the IRR> outweighed the applicable interest rate. Assessment using AHP showed that the caging system was preferable (0.650) than shepherd-based farming (0.350) with a value of inconsistency about 0.05.

Judul: Pengaruh kecepatan putar atomiser dan laju aliran terhadap karakteristik butiran pada atomiser piringan berputar
Abstrak: Penelitian ini didasarkan pada pentingnya karakteristik butiran dalam mempengaruhi mutu penyemprotan. Tujuan dari penelitian ini adalah mendapatkan pola hubungan antara kecepatan putar atomiser dan laju aliran semprotan dengan VMD butiran. Untuk pengamatan ini digunakan dua jenis piringan atomiser yaitu piringan terbuka dan piringan dengan penutup. Penyemprotan pada masing-masing piringan dilakukan dengan tiga tingkat laju aliran dan empat tingkat kecepatan putaran atomizer. Pola hubungan antar faktor dianalisa menggunakan analisis regresi berganda. Type piringan yang digunakan sangat mempengaruhi keragaman VMD butiran. Dengan menggunakan piringan terbuka didapatkan semprotan dengan VMD butiran yang lebih kecil dibanding jika menggunakan piringan tertutup. Tingkat keseragaman yang diperoleh relatif lebih baik dibanding pada piringan tertutup. Pada masing-masing piringan penyemprotan dengan beberapa tingkat kecepatan atomizer berbeda nyata pada selang kepercayaan 95%. Hubungan VMD butiran dengan kecepatan putaran atomizer menunjukkan korelasi negatif dengan tingkat penurunan yang semakin mengecil. Terhadap tingkat keseragaman butiran faktor N menghasilkan nilai ..dst
