Judul: Analisis Kelayakan Usaha Budidaya Ikan Cupang (Betta splendens) pada Usaha Bapak A. Arifin di Jakarta Pusat
Abstrak: Siamese fighting fish (Betta splendens) is commodities seed in Central Jakarta has an important role in the national economy. One of the most recognized fish farmers around the region is Mr. A. Arifin. The opportunity to meet the demands of Siamese fighting fish resellers has created a motivation to expand the business scale. The main purposes of this research are to analyze the feasibility of Mr. A. Arifin’s siamese fighting fish aquaculture business expansion through financial and nonfinancial aspects. The data processing was done by using both qualitative and quantitative method. Based on the analysis of financial and nonfinancial aspects, it can be concluded that the implementation of siamese fighting fish (Betta splendens) Mr. A. Arifin’s business expansion is feasible. The result of an analysis nonfinancial aspects seen from market aspects, the technical aspects, management aspects, legal aspects, social aspects, and enviromental aspects. The result of an analysis financial aspects seen from investment assessment criteria namely NPV, Net B/C, IRR, and PP. This business obtain NPV Rp 1 507 208 771.00, Net B/C 8. 684, IRR 88 percent, and long return on investment 2 years 4 months 3 days.

Judul: Analisis kelayakan pengembangan usaha ikan hias air tawar pada arifin fish farm, Desa Ciluar, Kecamatan Bogor Utara,Kota Bogor
Abstrak: Perikanan merupakan salah satu sektor ekonomi yang mempunyai potensi dan peranan penting bagi perekonomian Indonesia. Pembangunan perikanan merupakan bagian integral dari pembangunan nasional. Peranan sektor perikanan dalam pembangunan nasional terutama bisa dilihat dari fungsinya sebagai penyedia bahan baku pendorong agroindustri, peningkatan devisa melalui penyediaan ekspor hasil perikanan, penyedia kesempatan kerja, peningkatan pendapatan nelayan atau petani ikan dan pembangunan daerah, serta peningkatan kelestarian sumberdaya perikanan dan lingkungan hidup. Perikanan dan kelautan Indonesia memiliki potensi pembangunan ekonomi dan termasuk prospek bisnis yang cukup besar, sehingga dapat dijadikan sebagai sektor andalan untuk mengatasi krisis ekonomi. Salah satu pembudidaya ikan hias air tawar adalah Arifin Fish Farm yang terletak di Desa Ciluar, Kecamatan Bogor Utara, Kota Bogor. Usaha ini dimulai pada bulan Juni tahun 1997 yang bertempat di Bandung, dan pada awal tahun 1998 Arifin Fish Farm berpindah lokasi ke Kota Bogor untuk memudahkan dapat transportasi. Jenis ikan hias yang diproduksi Arifin Fish Farm antara lain Black Ghost (Apteronotus albifrons), Ctenopoma acutirostre, dan Patin (Pangasius sutchi). Alat analisis yang digunakan dalam penelitian ini menggunakan analisis cashflow, yaitu dengan NPV, Net B/C dan IRR. Alat analisis yang kedua menggunakan analisis sensitivitas (switching value).

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.
