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: Productivity, Body Condition Score And Glucose Semi Quantitative Urinalysis Study On Dairy Cow At Kunak Bogor Indonesia.
Abstrak: Penelitian ini bertujuan untuk mengetahui situasi yang berkenaan dengan produksi susu sapi yang belum mencukupi kebutuhan domestik dan cenderung mengalami penurunan produksi. Untuk itu studi tentang produktivitas, skor kondisi tubuh (BCS), dan analisis glukosa urin semi-kuantitatif dilakukan pada sapi-sapi perah di kawasan usaha peternakan KUNAK, Bogor Indonesia. Pengamatan dilakukan terhadap 30 ekor sapi perah yang meliputi sapi bunting (2 ekor), baru melahirkan (6 ekor), dan sapi tidak bunting (22 ekor). Berdasarkan hasil pengukuran BCS, tercatat bahwa sapi bunting berada pada nilai yang rendah (BCS =2,5, n=1) dibandingkan dengan nilai BCS standard (2.75-3.50). Sapi yang baru melahirkan berada pada nilai yang rendah (BCS= 2, n= 1; BCS = 2.2, n= 1, BCS=2.5, n= 4) dibandingkan dengan nilai BCS standar (3.00-3.25). Adapun nilai BCS sapi tidak bunting tergolong dalam kondisi normal. Reagen strip tes urinalisis semi kuantitatif dilakukan untuk memeriksa profil kelainan pada leukosit, nitrogen, urobilinogen, protein, pH, tekanan darah, keton, bilirubin, dan glukosa. Diketahui 1% glukosaria dari sampel urin dan diketahui sebagai kelainan yang sifatnya asimptomatik. Penelitian ini membuktikan bahwa semi kuantitatif urinalisis reagen strip tes dapat digunakan sebagai basis dalam manajemen harian pada peternakan sapi perah.

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.
