Judul: Kajian biaya manfaat program pengendalian dan pemberantasan brucellosis di Kabupaten Belu dan Kabupaten Kupang Provinsi Nusa Tenggara Timur
Abstrak: Belu district and Kupang district are endemic brucellosis area in East Nusa Tenggara Province. The present study evaluated of brucellosis control and eradication program in those districts using Cost Benefit Analysis. Brucellosis prevalence in Belu district 14,5% and Kupang district 2%. Two brucellosis control alternative programs were analyzed for Belu district: Program A was continuation of the present program (vaccination with average 57% coverage). Program B was intensive vaccination (80% coverage). Both programs were given positive NPV, B/C ratio > 1 and IRR which is higher than discount rate 15% and 20%, but implementation of Program B is more feasible (economic feasibility) than Program A while NPV and B/C ratio of Program B higher than Program A. Program B was also feasible from epidemiology aspect than Program A, because Program B will produce herd immunity that can reduce brucellosis prevalence. In Kupang district, two brucellosis alternative strategies were analyzed: Program A was continuation of the present program and Program B was intensive slaughtering of reactors for 6 years. Implementations of both programs were given positive NPV, B/C ratio > 1 and IRR which is higher than discount rate 15% and 20%. NPV of Program B was greater than Program A, but B/C ratio and IRR of Program A was greater than Program B, because of that, Program A was more economic feasibility than Program B. But, we chosen program which given greater beneficial both financial and non financial, and then by combine economy and epidemiology aspects, Program B was more suitable for Kupang district.

Judul: Kajian Strategi Pencegahan dan Pengendalian Bruselosis di Kalimantan
Abstrak: The strategy of prevention and control of brucellosis has been implemented in Kalimantan and this province of Indonesia has been declare free of brucellosis in 2009. Cattle movement from brucellosis infected areas to Kalimantan poses a high risk of entry and spreading of brucellosis in this island. The purpose of this study is to analyse the strategy of prevention and control of brucellosis in Kalimantan. The study used a descriptive analysis including human resources, policy environment (fund and infrastructure) and policy system. The result of this study proves that AQA has been able to implement, monitor and control animal movement in Kalimantan in preventing new cases of brucellosis. Each AQA involved in sending and receiving cattle has adequate qualified human resources with sufficient knowledge and attitude related with brucellosis although the majority they never have additional training about brucellosis. Most of AQA already have enough funds and infrastructure to implement the strategy. Policy system in controlling cattle movement in relation with prevention of brucellosis has been implemented, but is not fully executed according to OIE. A total of 14 District veterinary services in this study that have a function to control brucellosis does not have enough veterinarian and para-veterinarian to implementing the strategy to control brucellosis in their area. In general, the district veterinary officer have sufficient knowledge and good attitude toward brucellosis, although the majority they never have additional training about brucellosis. Most of district veterinary services do not have funds and infrastructure related with strategy control of brucellosis. And also most of district veterinary services do not implemented yet the strategy of control of brucellosis which is based on the ministry of Agriculture and OIE.

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.
