Judul: Clinical Profiles and Hematological Studies of Timor Deer (Rusa timorensis) in Bogor Development Center of Deer Captive Breeding Technology
Abstrak: Rusa timor (Rusa timorensis) merupakan jenis rusa asli dengan persebaran terluas di Indonesia. Informasi terkait gambaran klinis dan profil hematologi rusa timor di Indonesia khususnya di penangkaran masih terbatas. Penelitian ini bertujuan mempelajari gambaran klinis dan profil hematologi rusa timor yang ditangkarkan di Pusat Pengembangan Teknologi Penangkaran Rusa Bogor. Penelitian ini menggunakan 10 ekor rusa timor yang terdiri dari 5 ekor rusa jantan dan 5 ekor rusa betina. Hasil pemeriksaan profil klinis berupa suhu tubuh, frekuensi denyut jantung, dan frekuensi respirasi menunjukkan terdapat perbedaan antar jenis kelamin yang mana rusa betina menunjukkan nilai gambaran klinis yang lebih tinggi dibandingkan dengan rusa jantan. Hasil pemeriksaan hematologi menunjukkan nilai parameter hematologi rusa betina cenderung lebih tinggi dibandingkan dengan rusa jantan. Evaluasi sediaan ulas darah menunjukkan gambaran eritrosit berbentuk normal dan bentuk abnormal berupa poikilositosis dan anisositosis. Gambaran leukosit rusa timor memperlihatkan leukosit yang sama dengan leukosit mamalia pada umumnya. Hasil pengukuran morfometri sel darah menunjukkan terdapat perbedaan signifikan antar jenis kelamin pada morfometri eritrosit namun tidak didapati pada hasil pengukuran morfometri leukosit., Timor deer (Rusa timorensis) is a native deer species with the widest distribution in Indonesia. Information about clinical and hematological profiles of timor deer in Indonesia especially in captivity is still limited. The objective of this research was to study the clinical and hematological profiles of timor deer in Bogor Development Center of Deer Captive Breeding Technology. This research used ten timor deers that consist of five timor stags and five timor hinds. The results of clinical profiles such as body temperature, heart rate, and respiration rate showed differences between sex which clinical profiles of timor hinds were higher than timor stags. The results of hematological profiles showed the hematological values of timor hinds were tend to be higher compared with the timor stags. Evaluation of blood smear showed normal erythrocytes and abnormal forms such as poikilocytosis and anisocytosis. The leukocytes of timor deer showed the same morphology as common mammalian leukocytes’ morphology. The results of blood cell morphometry measurements showed significant differences between sex in erythrocytes’ morphometry but not in leukocytes.

Judul: Welfare Management and Health Status of Deer at Captivity Hutan Penelitian Dramaga, Bogor
Abstrak: Keberadaan rusa timor (Rusa timorensis), rusa sambar (Cervus unicolor), dan rusa bawean (Axis kuhlii) di alam perlu dipertahankan. Salah satu lembaga yang mendukung kegiatan konservasi eksitu tersebut adalah Penangkaran Rusa Hutan Penelitian Dramaga, Bogor. Penelitian ini dilakukan dengan menilai penerapan manajemen kesejahteraan satwa dan status kesehatan satwa. Data kesejahteraan rusa diperoleh melalui observasi lapang, wawancara dan pengisian kuisioner. Status kesehatan rusa berdasarkan kejadian infeksi cacing saluran pencernaan (helminthosis) diperoleh dengan melakukan pengambilan sampel feses, kemudian dianalisis secara mikroskopis melalui metode McMaster, flotasi sederhana dan saringan bertingat modifikasi. Hasil penelitian menunjukkan bahwa pengelolaan kesejahteraan rusa di penangkaran rusa Hutan Penelitian Dramaga tergolong “baik” dengan skor tingkat kesejahteraan satwa mencapai 73,03. Telur cacing parasit yang ditemukan yaitu Trichuris, Strongyloides dan Trematoda yang menginfeksi rusa, dengan derajat infeksi TTGT tergolong dalam kategori rendah., The existence of timor deer (Rusa timorensis), sambar deer (Cervus unicolor), and bawean deer (Axis kuhlii) in the wild needs to be preserve. One of the responsible institutions in ex-site conservation activities is deer captivity of Dramaga Research Forest, Bogor. The study was conducted to assess the implementation of animal welfare and animal health status. Data of deer walfare management was obtained by field observations, interview, and filling the questionnaire. Deer health status based on the gastrointestinal endoparasites infection (helminthosis) was obtained by collected faecal sample, then it was analyze with microscopic evaluation by McMaster, simple flotation and modification of sedimentation technique. The study shows that deer welfare management in deer captivity of Dramaga Research Forest was classified as a “good” with a score of animal walefare’s level up to 73,03. All animals were parasitized by Trichuris, Strongyloides, and Trematode with low infection intencity level EPG.

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.
