Judul: Keragaan asam lemak beberapa ikan pelagis dan demersal yang didaratkan di Palabuhanratu, Jawa Barat serta Muara Angke, Jakarta
Abstrak: Ikan-ikan pelagis dan demersal merupakan ikan ekonomis penting yang merupakan sumber protein hewani utama, tetapi sumber ini belum dapat dimanfaatkan secara optimal karena masih terbatasnya informasi mengenai kandungan nilai gizi dan komposisi lainnya pada sumberdaya perikanan. Penelitian ini bertujuan untuk mempelajari pengaruh habitat (dalam hal ini habitat pelagis dan demersal) dan faktor wilayah/lokasi (dalam hal ini Muara Angke, Jakarta dan Pelabuhanratu, Jawa Barat) terhadap kandungan asam lemak, khususnya asam lemak omega-3. Ikan-ikan pelagis yang diambil meliputi ikan kembung lelaki (Rastrelliger kanagurta), ikan tembang (Sardinella fimbriata), ikan selar (Caranx (Selaroides) leptoleptis), ikan tongkol (Euthynnus affinis), dan ikan kueh (Arropus atropus). Sedangkan ikan-ikan demersal yang diambil meliputi ikan bawal putih (Pampus argentus), ikan kakap merah (Lutjanus sanguineus), kakap (Lates calcarifer) dan ikan cucut (Carcharhinus falciformis). Pengamatan awal yang dilakukan meliputi analisis organoleptik, edible portion dan analisis makanan dalam perut ikan, sedangkan analisis kimiawi meliputi analisis proksimat (kadar air, abu, protein dan lemak) dan analisis keragaan asam lemak. Analisis keragaan asam lemak diperoleh dari hasil fraksinasi metil ester asam lemak dengan alat kromatografi gas sistem kolom kapiler. Penelitian ini dilakukan di Laboratorium Kimia Balai Bimbingan dan ...

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.
