Judul: Study of phenotypics and genetics diversity of some indonesian local goat sub populations and its strategies for sustainable use
Abstrak: The genetic resources of local goats are very important because it was well adapted to the local environment with low input management systems. Local goats are very potential for breeding stock program which suitable to the Indonesia local conditions. The study was carried out in order to describe the phenotypic and genetic of 6 sub-populations of Indonesian local goats based on the analysis of the morphometrics, mitochondrial DNA, Y Chromosome and GDF9 gene. The sampling was conducted in four of the Provinces in Indonesia, namely North Sumatra Province (Samosir goat n=42 in the Samosir District, Muara goat n=34 in the North Tapanuli district, Kacang goat n=217 in the Deli Serdang District), Central Java Province (Jawarandu goat n=94 in the Blora District); Province of South Sulawesi (Marica goat n=60 in the Maros District, Makassar City, Jeneponto District) and Nusa Tenggara Timur Province (Bengala goat n=96 in the Kupang area, Sikka District, Ende District). All of them were measured for morphometric and was bleeding to collect blood as DNA sources. The blood sample was preserve with absolute ethanol. DNA extracted was analyzed by PCR-RFLP methods for D-loop region, SRY gene and GDF gene on Indonesian local goat does.

Abstrak: This research was to study the morphological characteristic and estimating the genetic distance between local sheep in Indonesia with discriminant and canonical analyses. Observed sheep breeds were thirrtailed sheep from Jonggol (Bogor), Gamt sheep h m Ma~gawati (West Java) and fat-tailed sheq, h m Madura Island, Lndramayu (Central Java), Sumbawa Island, Rote Island, Kisar Island (Maluku) and Donggala Island. The number of sheep were randomly collected h m local farmers for 533 heads and h m unit of ranch was 285 heads. Body dimension studied were body weight, body length, wither height, chest width, chest depth, chest circumference, skull length, skull width, skull height, tail lenght, tail width, ear length and ear width.

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.
