Judul: Supplementation of Amino Acids and Sugar on Physiological Response and Performance of Thin Tailed Sheep Post Transportation
Abstrak: Pengangkutan ternak merupakan kegiatan yang dapat menimbulkan stres pada ternak yang ditunjukkan dengan perubahan fisiologis, penurunan bobot badan, dan masa pemulihan. Penelitian ini bertujuan untuk mengevaluasi pengaruh pemberian asam amino dan gula terhadap respon fisiologis, penurunan bobot badan dan waktu pemulihan domba setelah pengangkutan. Penelitian ini dilaksanakan di Laboratorium Lapangan Produksi Ternak Ruminansia Kecil Blok B Fakultas Peternakan Institut Pertanian Bogor. Penelitian menggunakan 8 domba jantan ekor tipis dengan rataan bobot badan 19,46 ± 3,77 kg berumur ± 1 tahun. Penelitian ini menggunakan uji-T dengan perlakuan; P0 = Kontrol (tanpa asam amino dan gula), P1 = pemberian 12 g/ekor asam amino dan 25 g/ekor gula, dengan empat ulangan tiap perlakuan. Transportasi dilakukan selama 8 jam. Hasil respon fisiologis menunjukkan bahwa suplementasi asam amino dan gula berbeda nyata terhadap suhu rektal (P<0,05) mampu mempertahankan suhu rektal pada kisaran normal sedangkan untuk penyusutan bobot badan dan waktu pemulihan tidak berbeda nyata (P>0,05). Penambahan asam amino dan gula mampu menahan cekaman panas dan dapat mempertahankan suhu rektal domba pada kondisi normal selama transportasi.

Judul: Behaviour of Lokal Sheep of Post Transportation with Aditional Feeding of Amino Acid and Sugar
Abstrak: Proses Transportasi ternak merupakan salah satu hal penting dalam sistem usaha perternakan domba. Tujuan dari penelitian ini adalah untuk mengkaji pengaruh pemberian gula dan asam amino terhadap tingkah laku domba lokal pasca transportasi. Tingkah laku yang diamati adalah perilaku makan, minum, resting, berdiri dan lokomosi dengan menggunakan teknik scan sampling dengan interval 1 menit selama 54 jam dan one zero time record. Penelitian ini menggunakan 8 ekor domba lokal yang dipelihara selama 22 hari. Data dianalisis menggunakan uji T untuk membandingkan P0 = Kontrol (Tanpa transportasi, gula dan asam amino) dan P1: dengan transportasi, gula dan asam amino. Hasil penelitian pada frekuensi dan durasi tingkah minum, berdiri, lokomosi dan frekuensi resting serta durasi makan ialah tidak berbeda nyata (P>0,05) antar perlakuan, namun pada frekuensi resting dan durasi resting menunjukan hasil yang berbeda sangat nyata (P<0,01). Pengamatan frekuensi dan durasi pada tingkah laku domba lokal yang paling sering dilakukan adalah resting dan paling sedikit ialah tingkah laku minum. Kata kunci : domba lokal, tingkah laku , transportasi, gula, asam amino, The process of livestock transportation is one of the important things in the sheep farming business system. The purpose of this study was to examine the effect of sugar and amino acids on the behavior of local sheep after transportation. The observed behavior was eating, drinking, resting, standing and locomotion behavior using scan sampling technique with 1 minute intervals for 54 hours and one zero time record. This study used 8 local sheep which were reared for 22 days. Data were analyzed using T test to compare P0 = Control (Without transport, sugars and amino acids) and P1: with transport, sugars and amino acids. The results of the study on the frequency and duration of drinking, standing, locomotion and resting frequency and duration of eating were not significantly different (P>0.05) between treatments, but the resting frequency and resting duration showed very significant differences (P<0, 01). The most frequent observation of the frequency and duration of the behavior of local sheep is resting and the least is drinking behavior.

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.
