Judul: Komposisi Karkas dan Non Karkas Kelinci Lokal Jantan Muda dengan Pemberian Pakan Limbah Tauge
Abstrak: Kelinci memiliki potensi untuk dikembangkan sebagai salah satu ternak potong. Kelinci termasuk ternak yang menyukai segala jenis tumbuhan termasuk limbah pasar seperti limbah tauge. Limbah tauge mengandung 13.26% protein dan 64.5% TDN. Tujuan dari penelitian ini adalah untuk mengevaluasi komposisi karkas dan non karkas kelinci lokal jantan muda yang berumur 12 minggu dengan pemberian pakan mengandung limbah tauge. Peubah yang diamati adalah bobot potong, bobot tubuh kosong, bobot karkas panas dan dingin, bobot potongan komersial, bobot komposisi karkas, proporsi karkas dan potongan komersial, bobot dan persentase non karkas. Penelitian ini menggunakan 12 ekor kelinci lokal jantan dengan bobot badan awal sekitar 747 ± 104.543 g. Ternak dipelihara selama 12 minggu dan dipotong pada umur 6 bulan. Penelitian ini menggunakan rancangan acak lengkap (RAL). Terdapat tiga jenis perlakuan: 100% pakan komersil (P0), 70% pakan komersil+30% limbah tauge (P1), dan 50% pakan komersil+50% limbah tauge (P2). Data dianalisis dengan menggunakan ANCOVA dengan menggunakan bobot tubuh kosong dan karkas panas sebagai kovariabel. Penelitian ini menunjukkan dengan penambahan limbah tauge menyebabkan bobot non karkas, bobot dan persentase potongan komersial hindleg dan lambung lebih tinggi dibandingkan tanpa penambahan limbah tauge. Penambahan limbah tauge tidak mempengaruhi bobot potong, bobot tubuh kosong, dan bobot karkas. Sehingga dapat disimpulkan bahwa limbah tauge dapat diberikan dalam bentuk segar untuk penggemukan kelinci hingga 50% menggantikan pakan komersil

Judul: Komposisi Karkas dan Sifat Fisik Daging Kelinci Lokal Jantan Muda dengan Pemberian Pakan Mengandung Limbah Tauge
Abstrak: The waste of mung bean sprouts are recidual bean sprouts production consisting of greenpeal and bean sprout fraction of sieving result for human consumption. This research was conducted to measure carcass composition and meat physical characteristic of the young local male rabbitfattened with feed containing of sprout waste. The carcass composition measurement consisted of the slaughter weight, carcass weight, commercial cut weight, non carcass weight, the weight of carcass component (meat, fat, bone), the percentage of carcass proportion and commercial cut. The physical characteristics of meat which be measure were pH, water holding capacity, drip loss, and meat tenderness. This research used 12 young local male rabbits with age about 12 weekswith treatments of feed100% as control (P1), 85% P1 with 15% waste of bean sprouts (P2), 70% P1 with 30% waste of bean sprouts (P3), and 55% P1 with 45% the waste of bean sprouts (P4). The animals were raised for 8 weeks. The study showed that the provision of sprouts waste treatment did not significantly affect (P>0.05) on carcass characteristic. Result of all treatment on carcass composition tested also showed no significant differences (P>0.05). Weight and percentage of commercial rabbit cut were not significantly differences (P>0.05) in all the commercial cut (foreleg, rack, loin and hindleg). Distributions of carcass components (muscle, fat and bone) were not significantly (P>0.05) different each commercial cuts. The weight and percentage of non carcass showed that not significantly (P>0.05). The physical characteristis of rabbit meat showed that significantly (P<0.05) different in pH variable. It was conclude that bean sprout waste could be used as rabbit feed without decreasing carcass and meat quality.

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.
