Judul: Ichthyoacanthotoxins pada Beberapa Jenis Catfish: Clarias gariepinus (Clariidae), Pangasius hypophthalmus (Pangasidae), Plotosus canius (Plotosidae)
Abstrak: Ichthyoacanthotoxins are toxins released through the pectoral fins (horn) by venomous fish. Order Siluroidea like CLARIAS GARIEPINUS, PANGASIUS HYPOPHTHALMUS, and PLOTOSUS CANIUS generally have pectoral fins as a defense mechanism. The research was conducted from February 2014 through September 2014 to determine anatomical structure of the venom gland and the chemical composition (acanthotoxins) present in the pectoral and dorsal spine. The results of histological analysis showed that the anatomical structure pectoral and dorsal spine consists of pieces of muscle, adipose layer, blood vessels, and there is a venom gland at CLARIAS GARIEPINUS with a long shaft, which is 1612.48 μm. The results showed that the proximate analysis, protein content of PLOTOSUS CANIUS is higher than the protein content of CLARIAS GARIEPINUS and PANGASIUS HYPOPHTHALMUS, while the fat content of CLARIAS GARIEPINUS higher than the fat content of PANGASIUS HYPOPHTHALMUS and PLOTOSUS CANIUS.

Abstrak: The present study was conducted to isolte, culture and identificatify of bacteria and parasitic worm from gills and digestive tract of catfish. A group of 10 of catfish were used, each gills and digestive tract was collected. The parasitic worms were colored with Semichon’s Acetocarmine for permanent staining. Differentiations and characterizations of variants isolate were based on biochemical reactions and Gram staining technique. Parasitic worms that can be identified from gills were Dactylogyrus sp. and Pseudodactylogyrus sp. The laboratory result shows that the gills and digestive tract of catfish were predominantly contaminated with Aeromonas sp. and Staphylococcus epidermidis, followed by Streptococcus sp., Edwardsiella tarda, Escherichia coli, Basillus sp. dan Vibrio cholerae.

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.
