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: Performance Determinants of Agricultural Extension in the City Tidore Islands North Maluku province
Abstrak: The role of agricultural extension agent from 1978 until the 1980's showed an important role in the development of national economy. In the 1990's the perceived role of the instructor began to decline, both in quantity and quality (performance level). The condition is occurring nationwide, including in the City Tidore Islands North Maluku province. Therefore we need a study that aims to analyze the factors thought to affect the performance of extension workers and formulating appropriate counseling strategies based on the implementation of the determinants of performance extension. Data collection conducted in mid-May through June 2011 thousands through census methods. The study population was defined as many as 56 people 67 people from the extension of existing civil servants. The results showed a correlation factor of age, period of employment, training, instructor perceptions of the tasks / jobs, media utilization, reward systems, active community participation, support supervision monitoring, planning, implementation, and evaluation of extension programs, applying principles of adult learning, and communication skills real contact with the performance of agricultural extension. The analysis showed a factor of training, perceptions of job/task, use of the media, community participation, and implementation of extension programs have real impact on the performance of agricultural extension. The average performance of extension agents were the category of being, where the extension is not optimal in planning, implementing and evaluating activities properly instructed. This is caused by a lack of creativity, initiative, and the ability of trainers to build cooperation and communication with the target extension. The implementation of agricultural extension that is not optimal in the City Tidore Islands affected several determinants of performance of extension, namely: (1) lack of competence in aspects of the implementation of extension programs. (2) lack of extension agents utilize the available media, (3) perception of extension agents to the task / job, (4) the intensity of training, and (5) active participation of the community.

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.
