Abstrak: Javan porcupine (Hystrix javanica) is one of the Indonesian endangered species due to hunting by local communities for commercial purpose. One of alternative methods to preserve the species is domestication through ex-situ breeding. The objective of this study was to examine the influence of koi fish pellet added to the ration on Javan porcupine carcass characteristics. This experiment used eight Javan porcupines fattened for eight weeks. The result showed that weight and percentage of muscle was significantly different (P<0,05). This research also had found M. Cutaneus trunci on the anatomical structure under skin layers of Javan porcupine. The effect of the addition of koi fish pellet into feed gave a significant effect on the meat weight of Javan porcupine but did not give a significant effect on commercial pieces of the carcass

Judul: Pengaruh Penambahan Pelet Ikan Koi Ke Dalam Ransum Terhadap Performa Landak Jawa (Hystrix javanica)
Abstrak: Javan porcupine (Hystrix javanica) is one of the endengered species due to hunting by local communities for commercial purpose. An alternative methode to preserve the species is domestication through ex-situ breeding, and feeding is one important factor that contribute obviously successful domestication. The experiment was conducted to study the effect of koi fish pellet added into control feed on the performance of javan porcupine. The experiment used eight javan porcupines; four animals where given control feed (K0) consisting of forest jaat leaf, yam, taro belitung, tomato, siamesse banana and sweet corn, and the other animals were given control feed and koi fish pellet feed (K1). The data were analyzed descriptively and differences between treatment means were determined using T-test. The results showed that the addition of koi fish pellet into control ration increased significantly (P<0.05) total dry matter intake but daily gain, feed efficiency and final body weight of javan porcupine were not significantly affected by such addition.

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.
