Judul: Performa Body Condition Score dan Bobot Badan pada Kelompok Ternak Domba Garut di BPPTD Margawati Garut.
Abstrak: Garut sheep is an indigenous species of Sunda’s land biodiversity which has uniques biological character such as rich carcass. However there is lack of information concerning their performance based on body condition score and body weight on garut sheep. For this challenge, we performed body condition score (BCS) and body weights measurement on 80 animals. The result show that BCS of male sheeps were increased followed by ages and body weights; such as 2 (18,22±1,45 kg) for male lambs, 2 (27,88±3,52 kg) for adolescent males and 3 (45,91±3,84 kg) for rams. BCS of female sheeps were increased followed by ages and body weights; 2,1 (20,71±6,47 kg) for female lambs, 2,5 (26,99±2,14 kg) for null para, and 2,6 (35,05±2,14 kg) for gestating animals, except lactating animals (2,1) and flushing animals (1,9). The phenomenon of mild decreasing BCS on flushing animals could be a biological character or a pathological state of garut sheep. In conclusion, increasing BCS of male and female sheeps followed by ages and body weights and the phenomenon of mild decreasing BCS on lactating and flushing animal suggested that further clinical nutritional improvement should be performed.

Abstrak: The level of productivity of sheep is closely linked to the health condition. In order to increased the health condition of Garut’s sheep we perform clinical evaluation based on physiological state. This study was conducted to assess the health of hoof, body condition scores (BCS) and its relation to body temperature as a parameter Garut’s sheep body temperature. This study used redomizing stall animals that consist of 10 male lambs, 10 male adolescents, 10 studs, 10 female lambs, 10 nolly-para females, 10 gestations, 10 flushing animals, and 10 lactating animals. Data analysis was performed using descriptive statistic. The result showed that the health of hoof tend to be related to the body temperature. The animal with high in normal ranging of temperature were found highly among studs that characterized by crack and long hoof. Other result showed that the score of BCS was tend to be related cenversely to the body temperature. In female sheep, the animals with low in normal ranges of temperature were found more in gestation animals (approcimately BCS 3, 39.4 ºC), and followed by flushing animals (approcimately BCS 3, 38.1 ºC) and lactating animals (approcimately BCS 2, 37.8 ºC). In male sheep animals (approcimately BCS 2.5, 41.0 ºC), and followed by male lambs (approcimately BCS 2.1, 39.8 ºC) and female lambs (approcimately BCS 1.5, 39.7 ºC).

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.
