Judul: Faktor-faktor yang berhubungan dengan peran unit pelaksana teknis dinas(UPTD) penyuluhan dan pos kesehatan hewan wilayah Cisarua, Kabupaten Bogor
Abstrak: One of a real action to develope the livestock farming is an extension for the farmers in the rural area.Technical Consultant and Husbandary Health Pos Service is one of the extension agency which can help the farmers to develop their farm by extension activity. The Technical Consultant and Husbandary Health Pos Service success is determined by hard work of extension agents and the farmers roles. From this side Technical Consultant and Husbandary Health Pos Service gets input to improve their performance so that the Technical Consultant and Husbandary Health Pos Service can improve their role in the farm development. The aims of the study are 1) to know the sheep farmer internal and external factors, 2) to know the extension agent internal and external factors, 3) to know the factors that correlate to the role of extension agency, 4) to analyze the internal and external farmer and extension agent in relationship to extension agency. This study was conducted from 7rd October until 21rd November 2005. The population of the study is all the sheep farmers and extension agent in subdistrict of Caringin. As many of 70 farmers were taken as sample using simple random sampling method and three extension agents as respondents. This study uses primary and secondary data. This study designed as a descriptive correlation survey. The internal and external farmers and extension agents relationship to extension agency were analyzed by Rank Spearman. Most of the farmers are 37-50 years old, graduated from elementary school, have 6-15 years of farming experience, have 0-0,49 ST of sheeps, 0-0.3 Ha land, farmers have the main occupation as farmer, has additional occupation as sheep farmer and the income of farmer is ranging from Rp. 450.000 to Rp. 800.000 per month. The extension agents are 38, 43, and 44 years old, graduate from Academy and have 11-19 years experience and also get Rp.925.000-1.400.000 income per month. The sheep farmer internal factors (age, education level, farming experience, farm land, income, occupation) have significant correlation to the agency role and intensity of extension, meanwhile the sheep farmer external factors (economic of scale, the market share and government policy) have no significant correlation to the agency role and intensity of extension.

Judul: Faktor-faktor yang Berhubunagn dengan Peran Unit Pelaksana Teknis Dinas (UPTD) Penyuluhan dan Pos Kesehatan Hewan Wilayah Cisarua Kabupaten Bogor
Abstrak: Salah satu tindakan nyata yang dilakukan untuk mengembangkan usaha ternak domba yaitu pembinaan bagi peternak di pedesaan. Unit Pelaksana Teknis Dinas (UPTD) Penyuluhan dan Pos Kesehatan Hewan merupakan salah satu lembaga penyuluhan yang dapat membantu peternak dalam mengembangkan usahanya melalui kegiatan penyuluhan. Keberhasilan UPTD Penyuluhan dan Pos Kesehatan Hewan dalam membina peternak tidak terlepas dari kerja keras para penyuluh dan peran serta aktif peternak. Dari dua sisi inilah UPTD Penyuluhan dan Pos Kesehatan Hewan mendapat masukan-masukan yang merupakan evaluasi untuk memperbaiki kinerjanya sehingga lembaga dapat lebih meningkatkan peran sertanya memajukan dunia peternakan. Penelitian ini bertujuan untuk 1) mengetahui faktor internal dan eksternal peternak domba, 2) mengetahui faktor internal dan eksternal penyuluh, 3) mengetahui faktor-faktor yang berhubungan dengan peran lembaga penyuluhan, 4) menganalisis hubungan faktor internal dan ekternal peternak dan penyuluh dengan kelembagaan penyuluhan. Penelitian ini berlangsung sejak tanggal 7 Oktober - 21 November 2005. Sampel diambil secara acak sederhana sebanyak 70 orang peternak dan tiga orang penyuluh sebagai responden. Penelitian didesain sebagai penelitian survei deskriptif korelasional. Data yang dikumpulkan terdiri dari data primer dan data sekunder. Analisis data meliputi analisis desktiptif dan korelasi Rank Spearman.

Judul: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
