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: Analisis Kelayakan Perencanaan Usaha Ikan Air Tawar di Mitra Fish Farm Kabupaten Bogor.
Abstrak: Usaha perikanan budidaya air tawar berkembang karena tingginya permintaan ikan. Teknologi kolam yang membantu penyediaan produksi adalah kolam air deras dan kolam tanah. Namun, tingginya biaya investasi awal pada pembuatan kolam maka perlu dikaji tingkat kelayakannya berdasarkan aspek non finansial dan aspek finansial. Penelitian ini bertujuan untuk menganalisis kelayakan pengembangan usaha kolam dan pakan buatan pada Mitra Fish Farm. Hasil analisis menyatakan bahwa budidaya ikan mas (skenario I) adalah skenario usaha terbaik diantara ketiga skenario. Hasil sensitivitas juga menyatakan bahwa penurunan jumlah produksi dan penurunan harga jual lebih sensitif dibandingkan dengan peningkatan harga pakan. Hasil ini juga mengindikasikan bahwa pakan alami dapat bertahan dari kenaikan harga hingga 280 persen

Judul: Approximation of the Median of Poisson Distribution Using the Relation of Poisson-Gamma Distribution
Abstrak: A major drawback of median is that median cannot usually be defined in closed form, even in the cases where their distribution functions are known. This study gives an approximation of the closed form for the median of the Poisson distribution by using the relation of Poisson-Gamma distribution. The approximation uses elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit Theorem. Furthermore, a closed form expression for the mean absolute deviation 􀜧|􀜰􀰒 􀵆 􀜯􀝁􀝀􁈺􀜰􀰒􁈻| is also studied. The median is relevant because of the fact that it minimizes the mean absolute deviation of a Poisson random variable (􀜰􀰒􁈻 by considering median as central tendency.
