Judul: Kandungan Mineral Baby Fish Ikan Mas (Cyprinus carpio) pada Berbagai Umur Panen
Abstrak: Baby fish merupakan ikan yang masih dalam tahap juvenile. Ikan mas balita menjadi tren saat ini khususnya di daerah Jawa Barat yang diolah dalam bentuk ikan balita goreng. Penelitian ini bertujuan untuk menentukan kadar mineral (Ca, Na, Mg, Fe, Cu, Zn) dan profil jaringan baby fish ikan mas (Cyprinus carpio) pada umur panen tiga, lima, dan tujuh minggu. Analisis mineral menggunakan Atomic Absorption Spectrophotometer (AAS). Mineral kalsium dan magnesium mengalami kenaikan yang signifikan seiring dengan bertambahnya umur panen, sedangkan natrium dan tembaga mengalami penurunan yang juga signifikan (P<0,05). Hasil analisis mineral besi dan seng menunjukkan angka yang fluktuatif. Histologi baby fish ikan mas cenderung mengalami peningkatan jumlah dan ukuran myomer pada umur tujuh minggu, dan myomer relatif lebih kompak.

Judul: Profil Asam Amino Baby Fish Ikan Mas (Cyprinus carpio) pada Berbagai Umur Panen
Abstrak: Baby fish is a term for fish fingerlings or for small-sized fish. Processed baby fish, which is fried, is very popular in West Java. This study was aimed to determine the difference of amino acid profile and the tissues description of baby common carp at various harvest time. The selected harvest time is three, five, and seven weeks. The amino acid profile was determined by HPLC. The total amino acids content of baby common carp increased with the increasing of the harvest time. The total dry basis amino acids content of baby common carp at the harvest time of three, five, and seven weeks, in a row, were 45.69%, 46.58%, and 60.46%. The highest amino acid content of baby fish in every harvest time was glutamate, while the lowest amino acid content was histidine and methionine. The myomer of baby common carp histologically developed with the increasing of the harvest time. The number of mucus-secreting cells and nutrition-absorbent cells in baby common carp’s intestinal also increased in the older baby common carp.

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.
