Judul: Patologi Infestasi Cacing Camallanus sp pada Ikan Manfish (Pterophyllum scalare) asal Raiser Cibinong
Abstrak: The aimed of this study is to describe the helminth infestation on diseased angelfish obtained from the forerunner of the Center of Ornamental Fish Business Services and Marketing at Cibinong (Raiser). The angelfish showed ulceration and hemorrhage on the skin near caudal fin with damaged of tail fin. Microscopic observations showed the most severe lesions found in intestine which was have transversal and longitudinal slices of helminthes larvae within the lumen also buried in mucosa. The morphology and size of the helminthes were observed within the Hematoxylin Eosin tissue section. The shapes and the sizes of larvae as compared studies of literatures lead to reveal nematode Camallanus sp as genus of helminthes found. Severe helminthes infestation within intestine causes indigestion and absorption of food which will further cause disturbances in other organs

Judul: Patologi infestasi cacing Camallanus sp pada ikan manfish (Pterophyllum scalare) asal Raiser Cibinong
Abstrak: Tujuan dari penelitian ini adalah untuk mendeskripsikan infestasi cacing yang menginfeksi ikan manfish yang diperoleh dari calon Balai Pelayanan Usaha dan Pemasaran Ikan Hias Cibinong (Raiser). Ikan manfish menunjukkan adanya ulserasi dan hemoragi pada kulit dekat ekor dan sirip ekor yang mengalami kerusakan. Pengamatan mikroskopis menunjukkan lesi utama pada usus ditemukannya potongan transversal dan longitudinal larva cacing pada lumen dan terbenam dalam mukosa usus. Morfologi dan ukuran cacing diamati dengan pewarnaan jaringan Hematoxilin Eosin. Bentuk dan ukuran larva cacing yang ditemukan berdasarkan studi literatur termasuk dalam kelas nematoda genus Camallanus sp. Infestasi cacing yang parah pada usus dapat mengganggu pencernaan dan penyerapan makanan sehingga merusak organ lain dalam tubuh.

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.
