Judul: Komposisi dan Distribusi Otot Kambing Kacang dan Kambing Peranakan Etawah yang Dipotong pada Bobot Sedang.
Abstrak: A total of 36 goats which consist of 26 kacang goats and 10 peranakan etawah goats were used to evaluate the muscle composition and distribution slaughtered in medium body weight (16.49 kg). Compositition of carcass in slaugter weight, carcass weight and a half weight carcass kacang goats were significantly different (P<0.01) than PE goats. The expensive muscle group (1+3+5) were 52.15% of carcasses muscle of kacang goats and 51.47% of carcassses muscle of peranakan etawah goats. The other muscle group 2, 4, 6, 7, 8 and 9 were 4.75, 12.02, 3.82, 3.20, 7.22 and 16.76% of kacang goats 5.34, 12.56, 4.07, 3.06, 7.11 and 16.42% peranakan etawah goats. The weight of group 1 (proximal thigh) on kacang goats was heavier than PE goats. Percentage of all weight in both breed goats have relatively equal proportions except group 2 that was percentage distal thigh muscle PE goats was larger than kacang goats at the medium slaughter weight.

Judul: Karakteristik Karkas dan Non Karkas Kambing Kacang dan Kambing Peranakan Etawah pada Bobot Potong 17 kg.
Abstrak: The objective of this research was to evaluate the characteristics of carcass and non carcass of 36 local goats which consists of 26 kacang goats and and 10 peranakan etawah (PE) goats of average slaughter weight at 17 kg. The data were analyzed using Analysis of Covariance (ANCOVA), with slaughter weight or left carcass weight as a covariable. The results showed that kacang goat had significantly higher (P<0.01) in slaughter weight, empty body weight, weight and percentage of carcass than PE goat (P<0.01). There were significantly different in the proportion of non carcass components such as head, skin, feet, blood, omental fat, heart, vesica urinaria, kidney and digestive tract. The result indicated that PE goat had significantly higher (P<0.01) in percentage of carcass bone and connective tissue and significantly lower in percentage of carcass fat than kacang goat (20.96% dan 2.8%). Generally, the kacang goat and PE goat slaughtered 17 kg of average body weight had carcass percentages of 41.02% and 34.31% and non carcass percentages of 33.81% dan 32.61%.

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.
