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: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
