Judul: Shigellosis pada kera berekor panjang
Abstrak: Tulisan ini bertujuan menguraikan penyakit shigel losis pada kera berekor panjang. Tulisan ini berupa hasil identifikasi yang penulislakukan dan tinjauan pustaka. - Penggunaan satwa primata bukan manusia pada saat se- karang makin berkembang, terutama dalam bidang riset bio .medik. Satwa primata yang banyak digunakan sebagai hewan percobaan adalah kera berekor panjang dan beruk ( Macaca nemestrina). Para peneliti memakainya dalam riset biomedik antara lain di bidang farmakologi, virologi dan imunologi, nutrisi, fisiologi dan sebagainya. Kera-kera yang diguna kan harus bebas dari segala penyakit yang dapat mempengaruh i percobaan/penelitian. Salah satu penyakit yang dapat mem pengaruhi baik hewan atau manusia adalah shigellosis. - - Shigellosis adalah suatu penyakit yang disebut juga sebagai disenteri dan dapat mengakibatkan penderita meng- alami diare, berak darah, dehidratasi, emasiasi dan kadang- kadang bisa terjadi prolapsus. Pada kasus yang berat pen derita dapat mati. Shigellosis disebabkan oleh bakteri ge- nus Shigella yang masuk ke dalam famili Enterobacteriaceae. Kera-kera yang baru ditangkap dari hutan umumnya tidak ada yang menunjukkan gejala shigellosis. Penyakit ini biasa- nya menyerang kera apabila kera tersebut dalam keadaan ..dst

Judul: Identification of Pseudomonas sp. and Shigella sp. from the Feces of Proboscis Monkeys (Nasalis larvatus), Endemic Primates of Borneo
Abstrak: Bakteri Shigella sp. dan Pseudomonas sp. merupakan bakteri patogen penyebab penyakit pencernaan paling umum pada hewan primata dan non human primate. Penelitian ini bertujuan mengisolasi dan mengidentifikasi bakteri patogen Pseudomonas sp. dan Shigella sp. yang terdapat pada feses Bekantan (Nasalis larvatus). Sampel yang digunakan adalah delapan sampel feses bekantan koleksi dari Laboratorium Bakteriologi, Divisi Mikrobiologi Medik, Sekolah Kedokteran Hewan dan Biomedis, Institut Pertanian Bogor. Isolasi dilakukan dengan metode cawan gores pada media MacConkey Agar (MCA) dan identifikasi dengan uji biokimia dan uji gula-gula mengacu pada Cowan and Steel’s Manual for the Identification of Medical Bacteria.Hasil isolasi dan identifikasi diperoleh tiga isolat yang memiliki karakteristik sesuai Shigella sp. dan satu isolat bakteri Pseudomonas sp., Shigella sp. and Pseudomonas sp. are the most common pathogenic bacteria that cause gastrointestinal diseases in primates and non-human primates. This study aims to isolate and identify the pathogenic bacteria, Pseudomonas sp. and Shigella sp., found in the feces of proboscis monkeys (Nasalis larvatus). A total of eight proboscis monkey feces samples were collected from the Bacteriology Laboratory, Medical Microbiology Division, School of Veterinary Medicine and Biomedical Medicine, Bogor Agricultural University. Bacteria in proboscis monkey feces were isolated by streak plate methode on MacConkey Agar (MCA) media and identification by biochemical test and sugar test, according to Cowan and Steel’s Manual for the Identification of Medical Bacteria. The test results confirmed that these bacteria accurately presented three isolates matching characteristics to Shigella sp. and one isolate of Pseudomonas sp.

Judul: Enhancement of photon absorbtion on BaxSr1-xTiO3 thin films semiconductor using photonic crystals.
Abstrak: In this research, has been conducted BaxSr1-xTiO3 (BST) thin films manufacturing for mole fraction x = 0.25, 0.35, 0.45, and 0.55; and concentration of 1 molar using chemical solution depositon (CSD) method. The materials, which are used in this research, are barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%], titanium isopropoxide [Ti(C12O4H28), 97.999%], gallium trioxide [Ga2O3], 2-methoxyethanol [H3COOCH2CH2OH, 99%] and 1 x 1 cm of transparent conductive oxide (TCO) glass as substrate. Two BST thin films are made that for BST thin films which are doped by 10% galium (BGST) as p-type layer and pure BST solution as n-type. BST solution is made by reacting barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%] and titanium isopropoxide [Ti(C12O4H28)] into 2-methoxyethanol solvent [H3COOCH2CH2OH, 99%] in accordance with mass gram for each x value. While, BGST solution is made in the same way as BST solution, plus adding gallium at 10% of the mass of BST. Once all materials are reacted, then vibrated using ultrasonic for 90 minutes, and followed by coating BGST / BST on the TCO substrate. Once the layer is formed, then annealed for 15 hours at temperature of 500 °C with increasing rate of 1.67 oC/minute. Characterizations of BST thin films with or without photonic crystals include the absorbance and transmittance in the visible light spectrum, as well as the electrical photoconductivity characterizations. From BST thin films without photonic crystals indicate that our thin films have light absorption area on almost the entire range of the visible light spectrum even to the infrared range with absorption value over than 67.6%, in addition, it can be seen that the maximum absorbance of BST thin films for all mole fractions lie in blue to green light spectrum region, 457 nm ≤ λ ≤ 570 nm and the minimum in yellow to red light spectrum region, 570 nm ≤ λ ≤ 678 nm. The largest absorbance is found at x = 0.25 with average absorbance value of 92.04% and maximum and minimum absorbance peaks at wavelength of 500.89 and 657.72 nm, respectively. At x = 0.35, average absorbance value decreased to 83.55% with maximum and minimum peaks at 505.73 and 613.68 nm, respectively. Then increased to 91.16% at x = 0.45 with maximum and minimum peaks at 506.04 and 618.56 nm, respectively. At x = 0.55, average absorbance value decreased to 80.12% with maximum and minimum peaks at 507.85 and 608.79 nm, respectively. Moreover, it can be seen that the addition of barium mole fraction leads to wider maximum absorbance or minimum transmittance peaks and narrower minimum absorbance or maximum transmittance peaks in the same range of the green and blue & red light spectrums, respectively. BST thin films with photonic crystals show increasing in absorption for all x values in the range of 3.04 into 13.33%. At x = 0.25, average absorbance percentage increased 3.96% from 92.4 into 95.68%, for x = 0.35 average percentage increased 7.07% into 89.45 from 83.55%. Furthermore, average absorbance of BST thin films at x = 0.45 increased 3.04% from 91.16 into 93.93% and x = 0.55 has
