Judul: Pertambahan bobot badan dan kondisi kesehatan monyet ekor panjang bunting di PT Bio Farma Persero
Abstrak: Monyet Ekor Panjang (Macaca fascicularis) adalah hewan yang memiliki kedekatan filogenetik dengan manusia sehingga sering dipergunakan dalam penelitian biomedis. Belum berhasilnya eradikasi poliomyelitis di dunia menyebabkan terjadinya peningkatan kebutuhan terhadap vaksin Polio. Pertambahan bobot badan (PBB) dan kondisi kesehatan M. fascicularis sebagai bahan baku dalam produksi vaksin Polio turut menentukan kualitas dan kuantitas vaksin yang dihasilkan. Penelitian ini bertujuan untuk mempelajari PBB dan kondisi kesehatan M. fascicularis bunting di penangkaran PT. Bio Farma (Persero). Sembilan ekor M. fascicularis bunting digunakan dalam penelitian ini. Pakan yang diberikan merupakan kombinasi dari monkey chow, jambu biji, pepaya, dan pisang kepok dengan formulasi tiga taraf kadar protein (17.19%, 12.91%. dan 8.60%). Masing-masing taraf kadar protein diberikan kepada tiga monyet. Tiga ekor M. fascicularis digunakan sebagai kontrol untuk masing-masing taraf. Pengaruh ketiga taraf pakan ini diolah dengan Analysis of Variance (ANOVA) menggunakan perangkat lunak Minitab. Obyek yang diberikan pakan dengan taraf protein tertinggi menunjukkan konsumsi protein tertinggi (16.28±0.62%) dengan efisiensi pakan tertinggi pula (94.72±3.60%). Hal ini berdampak terhadap total PBB yang tinggi (0.61 kg) serta rata-rata bobot fetus yang tinggi (0.35kg). Obyek kontrol menunjukkan pola konsumsi dan total PBB yang sama. Selain itu, kondisi kesehatan monyet diukur dengan parameter kadar total protein plasma dan hemoglobin. Kadar total protein plasma tertinggi pada obyek bunting dicapai oleh obyek dengan pakan bertaraf protein tertinggi. Hal ini berarti balıwa pakan perlakuan ini merupakan pakan yang paling efisien ditinjau dari ketersediaan protein yang siap dimetabolismekan di sel atau jaringan tubuh. Seluruh obyek penelitian mengalami penurunan kadar hemoglobin darah sebagai indikasi terjadinya anemia nutrisi selama kebuntingan, kecuali obyek bunting dengan perlakuan taraf protein 12.91%.

Judul: Profil Darah Monyet Ekor Panjang (Macaca Fascicularis) Yang Diberi Pakan Berenergi Tinggi Pada Periode Obesitas Empat Bulan Kedua
Abstrak: The aim of this research was to observe Macaque’s (Macaca fascicularis) blood and get information of the haematology. This research was done during four months with four times collected, at IndoAnilab, Taman Kencana, Bogor and were analysed in pathology and lipid laboratory of primate centre, Pusat Studi Satwa Primata (PSSP), Bogor. Macaca fascicularis were being fed with three kinds of diets. Two kinds were high energy diet with different composition, both with tallow but one with yolk egg and the other one with monkey chow. There were fifteen adult males M. fascicularis and every five monkeys got different maintenance. This research observed erythrocytes number (million/ml), haemoglobin concentration (g/dl), hematocrit value (%), Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH), Mean Corpuscular Haemoglobin Concentration (MCHC) the differentiations of leucocytes (eosinophil, neutrophil, basophil, lymphocyte and monocyte). The results of this research were high energy diet extremely significant (P<0.01) affected in erythrocytes number, haemoglobin concentration, hematocrit value, MCV and MCH. Periods nested in treatment extremely significant (P<0.01) affected in erythrocytes number, haemoglobin concentration, hematocrit value, MCHC and significant (P<0.05) affected in monocyte. Positive relationship was present between erythrocytes number, haemoglobin concentration and hematocrit value as well as MCV, MCH and MCHC. Negative relationship was present between lymphocyte and neutrophil. The highest influence showed in high energy diet with tallow and yolk egg. Keywords: haematology, high energy diet and long-tailed macaque (Macaca fascicularis)

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.
