Judul: Kajian Patogenesis Infeksi Buatan Bakteri Edwardsiella Ictaluri Pada Ikan Lele (Clarias Sp.)
Abstrak: Edwardsiella ictaluri merupakan penyebab penyakit Enteric Septicemia of Catfish (ESC) termasuk hama dan penyakit ikan karantina (HPIK) golongan II yang memerlukan kewaspadaan tinggi untuk dicegah masuk dan tersebarnya penyakit ini di wilayah Republik Indonesia. Bakteri ini menimbulkan hole in the head disease. Ikan lele (Clarias sp.) merupakan salah satu komoditas air tawar yang penting, dalam rangka pemenuhan peningkatan gizi masyarakat Indonesia. Masalah yang sering dihadapi pada budidaya ikan lele adalah serangan penyakit yang disebabkan oleh parasit dan bakteri. Ikan lele merupakan salah satu inang target infeksi E. ictaluri. Upaya pencegahan penyebaran penyakit ini dapat dilakukan dengan tindakan karantina melalui tindakan pemeriksaan penyakit ikan terhadap ikan lele yang dilalulintaskan. Sampai saat ini, perubahan patologi ikan lele yang terinfeksi E. ictaluri isolat lokal secara detail belum diketahui,

Judul: Upaya Pengendalian Infeksi Bakteri Edwardsiella tarda pada Ikan Lele (Clarias sp.) Menggunakan Ekstrak Kunyit (Curcuma longa)
Abstrak: Production target of catfish in Indonesia was up to 35% for 2013 and can be reached by free bacteria infection production including from Edwardsiella tarda. Turmeric (Curcuma longa) has been tested as antibacteria, and so its effectivity to catfish must be tested. The objectives of this research was to test turmeric extract on feed as additive to E. tarda infection on catfish. This research were test some methods to extract turmeric and in vivo test with prevention, curative, and control treatment, also positive and negative control three times for each test then analized with RAL method. The best result was the extraction by decoction for 15 minutes with 7,42 mm of inhibition zone. The bacteria density result of Lethal Dosage 50 (LD50) on catfish was 106 cfu/mL. This bacteria had some clinical signs like swelling, hemoraghic, and body ulcer, also gastroentritis and gas captivy. The best result of the survival rate in vivo test was the curative treatment with 86,67%. Specific Growth Rate, Growth Rate, and Growth of Absolute Length parameters did not differ significantly for each treatments.

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.
