Judul: Susceptibility of Candida albicans which Isolated from Poultry Abattoirs and Traditional Markets to Antifungal Agents of Ketoconazole, Itraconazole and Griseofulvin.
Abstrak: Kandidiasis, yang disebabkan oleh Candida albicans, merupakan salah satu penyakit mikosis terpenting dalam peternakan unggas. Seiring dengan berkembangnya teknologi pakan ternak, banyak faktor yang ikut mempengaruhi kesehatan unggas. Penggunaan anticendawan untuk pengobatan kandidiasis akan mempengaruhi resistensi anticendawan terhadap Candida albicans. Penelitian ini bertujuan untuk mengetahui kepekaan C. albicans, yang diisolasi dari tembolok, usus dan air, terhadap anticendawan ketokonazol, itrakonazol, dan griseofulvin. Penelitian ini juga menunjukkan bahwa C. albicansmasih peka terhadap pemberian anticendawan ketokonazol, itrakonazol, dan griseofulvin kecuali isolat C. albicans yang berasal dari potongan usus TPU Jambu Raya terhadap ketokonazol serta isolat C. albicans yang berasal dari potongan usus dan tembolok RPH Bubulak terhadap itrakonazol. Tidak terdapat perbedaan nyata (p>0,05) dalam kepekaan anticendawan antara C. albicans yang diisolasi dari contoh dengan referensi, kecuali griseofulvin yang lebih peka. Ketokonazol lebih efektif membunuh isolat C. albicans dibandingkan itrakonazol dan griseofulvin.

Judul: Keragaman Kepekaan Candida albicans yang Diisolasi dari Lokasi Peternakan Sapi Perah terhadap Beberapa Anticendawan
Abstrak: Candida albicans is a yeast species which often able to infect an animal, including dairy cow. Candida infections frequently leads to mycotic abortion and mastitis in dairy cow. Mycotic mastitis in dairy farm will be triggerred by various predisposing factors, such as using antibiotics and immunosuppressants for long period. The resistance activity of C. albicans against antifungal will be rised a serious problem at dairy farms. This research aims were determined the habitat where C. albicans can be able to survive in the dairy farms location. The isolated C. albicans were evaluated to antifungals sensitivity. This study showed that C. albicans was isolated from all milk samples. The all isolated C. albicans still remain sensitive to ketoconazole and griseofulvin, except C. albicans, which isolated from milk sample of Cipanas farm, were resistant to fluconazole, and C. albicans, which isolated from milk sample of Cisarua farm and vaginal swab sample of Kebon Pedes farm, were resistant to itraconazole, respectively. The research showed that antifungal ketoconazole more effective to inhibit the C. albicans growth than itraconazole, fluconazole, and griseofulvin.

Judul: Utilization of terra/MODIS L1B data for analysis of horizontal wind profile in the troposphere
Abstrak: This study was concerned with horizontal wind derived from data collected with the Moderate-resolution Imaging Spectroradiometer (MODIS) on board the NASA’s Earth Observation System (EOS)-Terra satellite. The aim of this study is to develop a method for the estimation of horizontal wind movement in the troposphere based on Navier-Stokes equation. The method was applied to a calibrated and geolocated Terra/MODIS L1B 1 km data set. The data inputs to estimate surface temperature are retrieved from TIR (Thermal Infrared) bands 31 (10.780 μm to 11.280 μm) and 32 (11.770 μm to 12.270 μm). The obtained surface temperatures were later used to approximate geopotential height on a constant-pressure surface by using the modified Poisson equation. The main assumptions used are the hydrostatic equilibrium, ideal gas law, constant lapse rate and constant acceleration of gravity. Based on the distribution of geopotential height, the pressure gradient force is measured by the gradient of geopotential on an isobaric coordinate to present the horizontal wind profile. For certain topographic areas especially in the mountain ranges, there was a disadvantage of using pressure as a vertical coordinate which lead to inaccuracy. In spite of that, Terra/MODIS L1B data with 1 km spatial resolution can be used to estimate the horizontal wind movement in the troposphere.
