Judul: Studi Kasus Proteinuria pada Sapi Perah di Kawasan Usaha Peternakan Cibungbulang, Bogor.
Abstrak: This research aims to study the proteinuria in dairy cows in Region Livestock enterprises (Kunak) Cibungbulang, Bogor, as a guarantee of health status to fulfill the needs of fresh milk in Indonesia. A total of 30 dairy cows were examined using semi-quantitative test strips, three cows that are not pregnant have proteinuria accompanied by increased frequency of pulsus. A total of three dairy cows proteinuria, one of whom suffered pyuria, hematuria, and glucosuria. Results were analyzed using a table of diagnosing disorders prerenal, renal, and Postrenal, dairy cows are thought to potentially suffer from glomerulonephritis, glomerulosclerosis, interstitial nephritis or urolithiasis. This study provides justification for the effective use of semi-quantitative urine test strips.

Judul: Pyuria  and  health  index  on  dairy  cattle  freisien  holstein at  farm  area  Cibungbulang  Bogor
Abstrak: Pendekatan manajemen kesehatan ternak adalah aspek penting untuk menjamin produktivitas susu sapi perah di kawasan usaha peternakan sapi perah cibungbulang bogor. Pendekatan ini dapat dilakukan dengan mengevaluasi indeks kesehatan hewan dan teknik uji urinalisis semikuantitattif secara praktis. Hasil evaluasi indeks kesehatan adalah 5 dari 30 ekor sapi dalam kondisi normal, 6 ekor sapi menunjukkan peningkatan frekuensi pernafasan, 7 ekor sapi menunjukkan peningkatan frekuensi pulsus, 12 ekor sapi mengalami peningkatan frekuensi pulsus dan frekuensi pernafasan. Hasil dari uji urin striptest semikuantitatif adalah 2 dari 30 sapi perah yang di uji mengalami pyuria. Satu ekor sapi positif pyuria mengalami peningkatan frekuensi jantung, frekuensi pernafasan dan suhu tubuh. Satu ekor sapi yang lain berada pada kondisi estrus., Herd health management approach is important aspect to insure milk productivity of dairy cattle at the dairy cattle farm area at Cibungbulang Bogor. This approach can be done by evaluating the animal health index as well as the result of semiquantitative urinalysis. The result of health index evaluation measuring by pulse and breath frequency refilled 5 of 30 cattle in normal condition, 6 cattle had increased breath frequency, 7 cattle had increased pulse frequency, and 12 cattle had increased pulse and breath frequency. The result of semiquantitative urine striptest showed that 2 of 30 cattle had pyuria. One of them had increased in temperature, pulse and breath frequency indicating of urinary tract infection. Another cattle possible in estrus condition.

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.
