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: 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

Abstrak: Growth of films Ba0,5Sr0,5TiO3 (BST) 1 M has been done with variation of annealing in hold time 8 hours, 15 hours, 22 hours, and 29 hours at constant temperature 8500C, above Si (100) substrate p-type, by using the sol-gel process method which followed with spin coating process at 3000 rpm for 30 seconds. Optics spectroscopy shows that BST film solar cells with annealing hold time 8 hours, 15 hours, and 22 hours, works effectively in wavelength ≥ 700 nm absorption range. Yet for sample with annealing hold time about 29 hours effectively absorb in ≤ 700 nm wavelength range. It obtained BST film refractive index at range 2.0 to 7.0 to wavelength range ±370-870 nm. Band gap BST film value based on annealing hold time 8 hours, 15 hours, 22 hours, and 29 hours respectively 2.60 eV; 3.12 eV: 3.24 eV, and 2.66 eV. Electrical conductivity value which obtained, indicate that the BST film is classified as semiconductor material with conductivity order 10-5-10-4 S / cm. The result of I-V photovoltaic characterization shows the BST film potentially to be a solar cells device with efficiency according to the annealing hold time 8 hours, 15 hours, 22 hours, and 29 hours in a row are 2.68x10-5%, 3.51x10-5%, 4.53x10-5% and 3.22x10-5%
