Judul: Characteristics of Estrus and Gestation Success of  Garut Female Lamb Fed Concentrate Diets with Different Protein Content
Abstrak: Penelitian ini bertujuan menganalisis pengaruh konsentrat terstandar yang ditingkatkan kandungan protein kasarnya (PK) terhadap karakteristik estrus dan keberhasilan kebuntingan calon induk domba garut. Penelitian ini menggunakan 20 ekor domba Garut dara dengan rataan bobot badan 36,37 ± 4,04 kg dan ditempatkan di kandang kelompok. Penelitian ini menggunakan rancangan acak kelompok (RAK) dengan 2 perlakuan dan 5 kelompok. Ransum kontrol = rumput + konsentrat komersial (60:40) dengan PK 11% dan ransum perlakuan = rumput + konsentrat terstandar (60:40) dengan PK 14%. Variabel yang diamati meliputi karakteristik estrus, kebuntingan pertama setelah pemberian perlakuan, jumlah fetus, persentase kebuntingan, dan korelasi body condition score (BCS) dengan jumlah fetus. Data yang diperoleh dianalisis dengan independent sample T-Test. Hasil penelitian menunjukkan bahwa penggunaan konsentrat terstandar nyata menurunkan (P<0,05) suhu vulva, namun cenderung meningkatkan (P<0,1) lendir vulva. Warna dan bentuk vulva relatif sama antar perlakuan. Terdapat korelasi positif antara BCS dan jumlah fetus. Pemberian konsentrat terstandar dapat meningkatkan persentase keberhasilan kebuntingan dari 70% menjadi 90%., This research aimed to analyze the effect of standardized concentrates that are increased in crude protein (CP) content on characteristics of estrus and success of the gestation of Garut female lamb. This study used 20 female lamb with an average body weight of 36.37 ± 4.04 kg and placed in group cages. This study used a randomized block design (RBD) with 2 treatments and 5 groups. Control ration = grass + commercial concentrate (60:40) with 11% CP and treatment ration = grass + standardized concentrate (60:40) with 14% CP. Variables observed included estrus characteristics, first gestation after treatment, number of fetuses, percentage of gestation, and correlation of body condition score (BCS) to the number of fetuses. The data obtained were analyzed with an independent sample T-Test. The results showed that the use of standardized concentrate significantly decreased (P<0.05) vulval temperature, but tended to increase (P<0.1) vulval mucus. Vulvar color and shape were relatively similar between treatments. There was a positive correlation between BCS and number of fetuses. Providing standardized concentrate can increase the percentage of successful gestation from 70% to 90%.

Judul: Profil Hematologi dan Metabolit Darah Domba Garut Bunting yang Diberi Konsentrat dengan Kandungan Protein Berbeda
Abstrak: PATMALIA. Profil Hematologi dan Metabolit Darah Domba Garut Bunting yang Diberi Konsentrat dengan Kandungan Protein Berbeda. Dibimbing oleh SRI SUHARTI dan LILIS KHOTIJAH Penelitian ini bertujuan untuk menganalisis pengaruh pemberian konsentrat dengan kandungan protein yang berbeda terhadap profil hematologi dan metabolit darah domba bunting. Penelitian ini menggunakan 20 ekor domba garut bunting berumur 1-2 tahun (bobot badan awal 36,365 ± 4,176 kg) dan 4 ekor Domba Dorper. Perlakuan yang digunakan adalah ransum kontrol = rumput Brachiaria humidicola + konsentrat komersial (60:40) dengan PK 11% dan ransum perlakuan = rumput Brachiaria humidicola + konsentrat terstandar (60:40) dengan PK 14%. Variabel yang diukur adalah hematologi (eritrosit, leukosit, hemoglobin, hematokrit, dan diferensiasi leukosit) dan metabolit darah (glukosa, trigliserida, total protein, albumin, blood urea nitrogen (BUN) dan kolesterol). Data dianalisis menggunakan independent simple T-test. Hasil penelitian menunjukkan bahwa penggunaan konsentrat terstandar nyata meningkatkan (P<0,05) kadar hemoglobin, hematokrit, total protein dan albumin darah domba bunting. Dapat disimpulkan bahwa penggunan ransum dengan protein kasar 14% dapat memperbaiki kadar hemoglobin dan hematokrit domba bunting awal., PATMALIA. Blood Hematology Profile and Metabolites of Pregnant Ewes Fed Concentrates with Different Protein Levels. Supervised by SRI SUHARTI and LILIS KHOTIJAH This research aims to analyze the effect of feeding concentrates with different protein levels on the blood hematology profile and metabolites of pregnant sheep. This research used of 20 ewes aged 1-2 years (initial body weight 36.365 ± 4.176 kg) and 4 male Dorper sheep. The treatments used were control ration = Brachiaria humidicola grass + commercial concentrate (60:40) with 11% crude protein (CP) and treatment ration = Brachiaria humidicola grass + standardized concentrate (60:40) with 14% crude protein. The variables measured were hematology (erythrocytes, leukocytes, hemoglobin, hematocrit, and leukocyte differentiation) and blood metabolites (glucose, triglycerides, total protein, albumin, blood urea nitrogen (BUN) and cholesterol). Data were analyzed using independent simple T-test. The results showed that the use of higher level of CP significantly increased (P<0.05) hemoglobin, hematocrit, total protein and albumin levels of pregnant sheep. It can be concluded that the use of rations with 14% crude protein can improve hemoglobin and hematocrit levels of early pregnant sheep.

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.
