Judul: Penampilan reproduksi kambing boer : Studi kasus di PT. Widodo Makmur Perkasa, Propinsi Lampung
Abstrak: Kegiatan lapangan untuk penulisan skripsi ini sebagai syarat menjadi Sarjana Kedokteran Hewan IPB dilakukan dalam bentuk studi kasus penampilan reproduksi kambing Boer yang dilaksanakan bulan November 2007 sampai Juli 2008 di PT. Widodo Makmur Perkasa, Propinsi Lampung. Studi kasus ini bertujuan untuk mengetahui manajemen reproduksi kambing Boer, berbagai masalah yang sering muncul dalam pemeliharaan kambing Boer, serta tingkat keberhasilan munculnya kebuntingan pada inseminasi buatan dan perkawinan alami pada kambing Boer. Studi kasus dilakukan berdasarkan metode survey deskriptif dengan pengumpulan data primer dan data pendukung lainnya. Data primer didapat dari hasil wawancara dengan para pekerja yang berwenang di PT. Widodo Makmur Perkasa dan pengamatan secara langsung di PT. Widodo Makmur Perkasa. Data lainnya diperoleh dari data yang dimiliki oleh PT. Widodo Makmur Perkasa, literatur, dan internet. Hasil studi menunjukkan bahwa nilai Conseption Rate (CR) secara kawin alam sebesar 91 % dan 80 % secara inseminai buatan. Nilai Service per Conseption (S/C) pada kambing Boer yang dikawinkan secara kawin alami sebesar 1,1 dan inseminasi buatan adalah 1,2. Data menunjukkan bahwa nilai S/C secara IB lebih tinggi dibandingkan dengan kawin alam. Calving Interval ( CI ) kambing Boer terjadi selama 8 bulan. Kelainan yang sering muncul dalam pemeliharaan kambing Boer yaitu anak lahir prematur, tidak mampu bertahan hidup karena kondisi badannya terlalu lemah akibat kelahiran yang abortus, dan patah tulang akibat transportasi.

Judul: Penampilan reproduksi kambing boer (Studi kasus di Pusat Bioteknologi JPHPT Keningau, Sabah, Malaysia)
Abstrak: The aim of this research was to study the management of Boer goat handling, to identify the impacts that often risen in Boer goat handling and search for solution and to determine the increased appearance of Boer goat reproduction for population. Population data that is obtained in 2008, 2009 and 2010 amounted to 108, 179 and 116 goats respectively. Birth data for the three years respectively was 19, 60 and 56 goatling with their mortality data by 4, 14 and 19 goats. The results of this study showed that the method of goat breeding is still used mating and artificial insemination (AI) was introduced in 2011. Reproductive problems that arise at the center is the goats who gave birth of goats, only first/second goatling would be nursed and the other goatling will be ignored. The highest case of disease that infected the goat was Strongylosis (29.5%), Meliodiosis (28.7%), Coccidiosis (22.4%) and Pasteurellosis (12.7%) respectively.

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.
