Judul: Produksi antibodi anti axcretory secretory (E/S) dan anti whole worm extract (WWE) cacing Raillietina echinobothrida dengan dosis antigen bertingkat pada kelinci
Abstrak: Penelitian ini dilakukan untuk mempelajari pembentukan antibodi anti E/S dan antibodi anti WWE pada kelinci yang disuntik antigen Excretory/Secretory (E/S) dan antibodi anti Whole Worm Extract (WWE), dengan dosis bertingkat 200 µg/kg BB, 300 µg/kg BB 600 µg/kg BB serta minggu ke-9 pada dosis 200 µg/kg BB. Antibodi anti WWE terbentuk mulai minggu ke-5 pada dosis 300 µg/Kg dan 600 µg/Kg BB serta minggu ke-11 pada dosis 200 µg/kg BB. Antibodi anti E/S lebih cepat terbentuk daripada antibodi anti WWE. Kecepatan pembentukan antibodi dipengaruhi oleh dosis dan jenis antibodi. Terdapat reaksi silang antara antibodi anti E/S dengan antigen WWE dan antibodi WWE dengan antigen E/S.

Judul: Produksi Antibodi Poliklonal Antiekskretori/Sekretori (E/S) Fasciola gigantica Isolat Asal Domba Dan Kerbau Pada Kelinci
Abstrak: The research was designed to study method of polyclonal antibody (Ig G) anti-Excretory/Secretory (E/S) Fasciola gigantica production in rabbit. Two antigens of E/S Fasciola gigantica (E/S Fasciola gigantica from buffalo and E/S Fasciola gigantica sheep) were immunized to rabbit, at dose level 150 μg/animal. Freund’s adjuvant added to antigen with the equal volume (1:1). The first immunization was done intravenous (i.v) without adjuvant. Second immunization were gave subcutaneous (s.c) with combination of antigen-Freund’s adjuvant complete. The third until sixth immunizations were done subcutaneous (s.c) with combination of antigen-Freund’s adjuvant incomplete. Blood samples were collecting every one week after the third immunization. To evaluated antibody anti Excretory/Secretory (E/S) Fasciola gigantica development, the sera tested using Agar Gel Precipitation Test (AGPT). The result showed that the rabbit immunized by E/S protein of Fasciola gigantica from sheep, able to develop antibody faster (4 weeks post infection) than the rabbit which immunized by E/S protein of Fasciola gigantica from buffalo (12 weeks post infection). In the same time, cross reactivity between antigens appear from the antibody that produced from each rabbit.

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.
