Judul: Potensi Rumah Potong Hewan Pemerintah Sebagai Penyedia Daging Sapi Di Wilayah Bogor.
Abstrak: Bogor is the one important city that have a high demand of meat in jabodetabek area. Bogor is divided to districts and the city which have population 5 202 097 and 1 019 013 resvectively. Capita consumption of meat are 3.65 grams day-1 and 22.08 grams day-1. This research was conducted by survey , then analyzed by descriptive and counted the location quotient ( LQ ). The LQ value of Bubulak slaughter house was 4.26 and Cibinong slaughter house was 3.11 which greater than one (LQ>1), this data showed a second slaughter house were the base of meat production in Bogor. The LQ value of Galuga slaughter house (0.62) and Jonggol slaughter house (0.74) less than one (LQ<1), that means both as a second slaughter house with non base meat production in the Bogor area. Meat production of each slaughter house of Bubulak, Cibinong, Galuga, and Jonggol distributed in Bogor area with each production are 5 250.99 kg day-1, 3 827.25 kg day-1, 765.45 kg day-1, and 918.54 kg day-1. The total daily demand of meat in Bogor District was 19 003.26 kg and the Bogor City was 22 369.48 kg. However, the meat production of government slaughter house distributed to Bogor area is 10 762.32 kg day-1. The government slaughter house could have self sufficient as the potential meat provider in Bogor with the value of slaughter is optimized of slaughter capacity.

Judul: Dampak Kenaikan Harga Daging Sapi terhadap Pola Konsumsi Pangan Sumber Protein Hewani di Kabupaten Bogor.
Abstrak: One kind of food which has important role in developing the food security and create human resources who has healthy quality is food animal proteins. The government is targeting food consumption of animal protein as much as 7.2 g/capita/ day in 2014. Food sources of animal protein can be derived from livestock or fishery products like ruminant meat, poultry, fish, eggs, and milk. This study aims to analyze the pattern of household consumption in Bogor Regency, analyze the level of demand elasticity, and perform simulations to analyze the impact of higher prices for meat. The data used comes from SUSENAS 2012 with 1125 households in Bogor Regency. The analytical method used was descriptive analysis and model of Almost Ideal Demand System (AIDS). The analysis showed that the type of ruminant meat consumption group was very inelastic and have a lower level of consumption than other animal protein foods. People in Bogor Regency consume more fish than ruminant meat. Increasing the prices of beef could make other public consumption for food source of animal proteins is down. Food protein consumption for the people of Bogor regency have met the target set by the government

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.
