Judul: Perbandingan Profil Leukositogram Sapi Peranakan Ongole Sebelum dan Setelah Program Produksi Embrio
Abstrak: Profil leukositogram merupakan salah satu parameter yang dapat memberikan gambaran kondisi kesehatan suatu hewan. Perkembangan embrio pada fase awal kebuntingan sangat rentan dipengaruhi oleh kondisi kesehatan induk. Oleh karena itu, pemeliharaan kesehatan hewan dengan mengevaluasi profil leukositogram diharapkan mampu meningkatkan keberhasilan program produksi embrio terutama pada sapi Peranakan Ongole. Namun, kajian tentang profil leukositogram sapi Peranakan Ongole cukup terbatas. Tujuan dari penelitian ini adalah untuk mengetahui gambaran perbandingan profil leukositogram sapi peranakan ongole sebelum dan setelah perlakuan program produksi embrio. Diharapkan hasil dari penelitian ini dapat berguna dalam mengetahui nilai profil leukositogram pada sapi PO. Penelitian ini menggunakan sepuluh ekor sapi Peranakan Ongole yang diberi perlakuan program produksi embrio. Tidak terdapat hubungan antara program produksi embrio dengan profil leukositogram sapi PO. Berdasarkan pengamatan, gambaran profil leukositogram antara sebelum dan setelah perlakuan program produksi embrio secara keseluruhan tidak didapati perbedaan yang signifikan. Namun saat profil leukositogram diamati per individu, terdapat perubahan yang terlihat jelas pada tiap variabel meskipun secara keseluruhan nilai parameter masih berada pada rentang normal., Leukocytogram is one of those parameters that shows general representation of cattle health. Since embryo development in early pregnancy can easily interrupted in any changes, especially if it related to maternal exposure, maintaining maternal health in cattle is expected. Evaluating leukocytogram in embryo production program can be done to monitor cattle health. This procedure is proposed that the outcome probability of the programe of embryo production, especially for Ongole crossbreed cattle. However, the information about Ongole crossbreed cattle hematology are limited. Range value of leukocytogram in Ongole crossbreed cattle is expected to be known as the output of the experiment. This conducted study serves to evaluate the difference in leukocytogram value in Ongole crobreed cattle within embryo production program by using ten cattles as the samples. In general, there is no correlation between changes in leukocytogram profile and embryo production program. The overall result shows that there is no difference in leukocytogram changes after the treatment. However, some sample shows remarkable changes even though the value of leukocytogram still within normal range.

Judul: Erythrogram Profile of Ongole Cross Breeds in Before and After Superovulation
Abstrak: Superovulasi adalah pemberian hormon pada ternak betina donor sehingga menghasilkan beberapa oosit atau sel telur, dimana secara normal hanya dihasilkan satu oosit pada setiap estrus. Penelitian ini bertujuan untuk mengetahui profil eritrogram sapi peranakan ongole (PO) sebelum dan sesudah superovulasi. Sebanyak 10 ekor sapi PO dari Balai Embrio Ternak Cipelang (BET) digunakan dalam penelitian ini. Sampel darah diambil dari vena coccygeal sebelum dan sesudah superovulasi. Kegiatan dalam penelitian ini meliputi pemasangan implan untuk sinkronisasi estrus, superovulasi, inseminasi buatan dan produksi embrio. Informasi tentang efek superovulasi terhadap profil eritrogram masih sangat terbatas. Analisis eritrogram dapat menggambarkan status kesehatan hewan. Pemerikasaan eritrogram meliputi jumlah eritrosit atau sel darah merah (RBC), kadar hemoglobin (HGB), nilai hematokrit (HCT), indeks eritrosit (MCV, MCH, dan MCHC) serta RDWc. Darah utuh yang digunakan berisi antikoagulan EDTA dan dianalisis menggunakan mesin hitung otomatis (hematology analyzer). Hasil penelitian menunjukkan RBC, HGB, HCT, MCV, MCH, MCHC dan RDWc menunjukkan nilai yang masih dalam kisaran normal. Superovulasi tidak mempengaruhi profil eritrogram., Superovulation is a procedure of giving hormones to female livestock resulting several oocytes, that normally only one oocyte is produced at each estrus. This study aimed to know the erythrogram profile of Ongole Crossbreed (PO) cattle before and after superovulation. A total of 10 samples of PO cattle from the Balai Embrio Ternak Cipelang (BET) were used in this study. Blood samples were taken from coccygeal vein before and after superovulation. Embryo program activities include insertion of implants for synchronization of estrus, superovulation, artificial insemination and embryo production. Information about the effect of superovulation on the erythrogram profile is still very limited. Erythrogram analysis can describe the health status of the animal. Erythrogram examination include erythrocytes count or red blood cells (RBC), hemoglobin levels (HGB), hematocrit value (HCT), erythrocyte index (MCV, MCH, and MCHC) and RDWc. The whole blood contains the anticoagulant EDTA and were analysed using an automatic counting machine (hematology analyzer). The result showed RBC, HGB, HCT, MCV, MCH, MCHC and RDWc showed values that were still in the normal range. Superovulation do not affect on the erythrogram profiles

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.
