Judul: Komponen Karkas dan Sifat Fisik Daging Sapi PO dan Kerbau Rawa yang Digemukkan Menggunakan Ransum yang Disuplementasi Campuran Garam Karboksilat Kering
Abstrak: Peranakan Ongole cattle and buffalo are meat producing ruminants commonly found in Indonesia. The study was aimed to examine the carcass yield and meat quality from local cattle and buffalo fattened on feedlot ration supplemented by protected lemuru fish oil in the form of dried carboxylate salt mixture (DCM). They were fattened for approximately 2,5 month. The experiment used six swamp buffalo and eight Peranakan Ongole cattle. The data was analyzed by factorial design with two factor treatment. The first factor was species (cattle and buffalo) and the second factor was ration (supplemented and non supplemented ration with dried carboxylate salt). The result showed that they were no interaction between species and ration on carcass productivity and meat quality characteristics. Carcass productivity and meat quality characteristics were not influenced by ration treatment’s factor. However, bone, tenderness, meat color and fat color were significantly influenced (P<0,05) by species. Buffalo carcass contained less bone compare to Peranakan Ongole carcass. The meat from buffalo was significantly more tender, darker in color, and the fat was lighter in color compare to beef.

Abstrak: Buffalo is a potential meat producing animal. There is an increasing demand of buffalo meat in Indonesian. The study was aimed to examine the fatty acids composition and chemical characteristic of meat from cattle and buffalo fatten on feedlot ration supplemented by protected lemuru fish oil in the form of dried carboxylate salt mixture (DCM). The research used six swamp buffalo and eight Ongole grade cattle. They were assigned to 2x2 factorial model with two animal species (cattle and buffalo) and two level ration (suplemented and not supplemented ration with dried carboxylate salt).The results of this study showed that swamp buffalo and Peranakan Ongole cattle fatten on feedlot ration using protected lemuru fish oil in the form of DCM, produced meat with similar chemical characteristic. Meanwhile, they were significant interaction between ruminant species and ration on fatty acid composition. In buffaloes the addition of the protected lemuru fish oil could significantly decreased (p<0,05) the saturated fatty acid but significantly (p<0,05) increased the unsaturated fatty acid in meat. However, this was not the case for cattle.

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.
