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 Cross Boer (Jawarandu-Boer) “Studi Kasus di PT. Widodo Makmur Perkasa, Propinsi Lampung”
Abstrak: This case study aimed at knowing the management and problems that often in the maintenance of the Cross Boer goat, identify the level of the precnancy in the natural breeding and artificial insemination, and to know the appearance of the Cross Boer goat reproduction. This study was carried on November 2007 until July 2008, based on the method survey descriptive with the primary data collection through the interview from several staff in PT Widodo Makmur Perkasa. The other data was collect from the available data in PT Widodo Makmur Perkasa. The data that was received afterwards was analysed qualitatively. The observation showed that level success of the Conseption Rate value (CR) or the level success of the reproduction by means of being natural breeding was higher (83%) compared with the Artificial Insemination method (70%). The Service per Conseption (S/C) of i natural breeding is 1,2 and the Artificial Insemination is 1,4. This data showed that S/C of Artificial Insemination is higher than Natural Breeding.

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.
