Judul: Analisis Kelayakan Pengembangan Usaha Ikan Hias Air Tawar pada Aquarium Jaya, Desa Curug Jaya, Kecamatan Bojongsari, Depok, Jawa Barat
Abstrak: Aquarium Jaya merupakan pembudidaya ikan hias jenis tetra terbesar di Desa Curug Jaya Kecamatan Bojongsari, Depok, Jawa Barat yang akan melakukan pengembangan usaha. Hasil analisis kelayakan pada penelitian ini terdiri dari kelayakan non finansial, kelayakan finansial, dan analisis sensitivitas. Berdasarkan hasil analisis aspek non finansial yang mencakup aspek pasar, aspek teknis, aspek manajemen, aspek hukum, aspek sosial, dan aspek lingkungan usaha pengembangan Aquarium Jaya layak untuk dijalankan. Hal ini dikarenakan masih terdapat permintaan yang belum terpenuhi dan usaha ini memberikan dampak positif bagi warga sekitar. Hasil dari analisis finansial pengembangan diperoleh nilai NPV sebesar Rp2.162.665.131,00. IRR sebesar 99 persen. Net B/C yang diperoleh dari rencana pengembangan sebesar 6, dan payback periode selama 2,12 tahun. Hasil analisis sensitivitas pada rencana pengembangan usaha Aquarium Jaya pada kondisi kenaikan harga pakan sebesar 35 persen menghasilkan NPV sebesar Rp 1.944.442.278,00, Net B/C 5, IRR sebesar 87 persen, dan PP 2,21 tahun. Kondisi penurunan produksi sebesar 30 persen menghasilkan NPV sebesar Rp 674.577.976,00, Net B/C 2, IRR 31 persen, dan PP 3,61tahun.

Judul: Analisis kelayakan pengembangan usaha ikan hias air tawar Iwan Wahana Fish Farm Kota Bekasi
Abstrak: Ornamental fish is one of the new commodity that still require more intensive development efforts in Indonesia. Iwan Wahana Fish Farm as a business entity engaged in the field of cultivation of freshwater ornamental fish have not been able to meet the demand against the increasing every year, so it will be done to expand the scale of business development. The purpose of this research is to analyze the feasibility of the development of freshwater ornamental fish Iwan Wahana Fish Farm in Bekasi based on market aspects, technical aspects, and financial aspects. The analysis tool used are the TOWS analysis, EOQ method, NPV, Net B / C, IRR, Payback Period, and Switching Value Sensitivity analysis supported by Microsoft Office Excel software. As a result, market aspects and technical aspects of business development declared eligible to run. On the financial aspects of business development at Iwan WahanaFish Farm feasible with NPV of Rp 377 989 000; Net B / C of 2.29; IRR of 46% and payback period for 1.5 years. The results of the sensitivity analysis calculation of switching values obtained maximum changes decrease the survival rate of freshwater ornamental fish by 48.98%, the maximum change in market demand decline of 24.82%, and the maximum change for the increase in raw material costs amounted to 51.55%.

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.
