Judul: Analisis Kelayakan Pengembangan Usaha Beras Merah Organik (Studi Kasus; UD Sirtanio Banyuwangi, Jawa Timur)
Abstrak: Organic brown rice is a healthy rice with high natural fibre and eco-friendly. One of the organic brown rice producing area in East Java is Banyuwangi. UD Sirtanio is one of the organic brown rice company that established due to the information about high demand of organic brown rice in Banyuwangi and its surroundings. The purpose of this research is to analyze the feasibility of organic brown rice business development in UD Sirtanio through financial and non financial aspects with the switching value toward the mark-up of grain and decline of yield value. Leasing analysis has previously been done and the results show that the business development plan more profitable than current conditions. The business development plant in this research consists of two scenarios with different capital sources. Scenario I uses its own capital resources, while scenario II uses capital source combination of its own capital with bank loans capital. Based on the results of the analysis of the financial and non financial aspects can be concluded that organic brown rice business development in UD Sirtanio is feasible to be realized. From the business development of scenario I, the NPV earned is Rp2 924 093 674, Net B/C is 4.771, IRR is 54 percent, and the payback period for 2 years 9 months 28 days. While the business development of scenario II, the NPV earned is Rp1 498 919 714, Net B/C is 7.255, IRR is 94 percent, and the payback period for 2 years 17 days. In addition, this business is more sensitive toward the decline of yield value than the mark-up of grain, which is 0.705759509 for scenario I and 0.752592975 for scenario II.

Judul: Organic Rice Farming Business Development Strategy in Serdang Bedagai Regency
Abstrak: Provinsi Sumatera Utara memiliki lahan yang sangat subur untuk pertanaman padi serta cukup potensial untuk pengembangan pertanian organik. Produk beras organik sudah dikembangkan di Provinsi ini bahkan sudah mendapatkan sertifikasi dari Penjaminan Mutu Organik (PAMOR). Salah satu sentra padi organik yang dikembangkan di Provinsi Sumatera Utara adalah sentra padi organik di Kabupaten Serdang Bedagai, yaitu Kecamatan Perbaungan (di Desa Lubuk Bayas dan Desa Tanah Merah) dan di Kecamatan Teluk Mengkudu (di Desa Pematang Setrak). Pelaksanaan pengembangan padi organik di Kabupaten Serdang Bedagai ini cukup prospektif, namun belum didukung oleh penelitian mengenai agribisnis padi organik, terutama yang dikaitkan dengan aspek kewilayahan (spasial). Penelitian ini bertujuan untuk menyusun strategi pengembangan padi organik di Kabupaten Serdang Bedagai yang juga melihat pola spasialnya. Metode yang digunakan untuk menjawab tujuan tersebut mencakup identifikasi existing lokasi lahan sawah padi organik melalui citra satelit dan analisis ANN untuk melihat pola spasial antar subsistem agribisnis, kemudian analisis R/C rasio usahatani, dan analisis AWOT untuk mendapatkan prioritas strategi dalam upaya pengembangan usaha tani padi organik. Hasil penelitian menunjukkan bahwa luas lahan pertanian yang dikembangkan di Kabupaten Serdang Bedagai saat ini baru mencapai 13,31 ha. Adapun hasil analisis ANN menunjukkan bahwa pola sebaran lahan sawah dan subsistem agribisnis padi organik ada dua, yaitu dispersed (menyebar) dan clustered (mengelompok), dan lokasi antar subsistem jaraknya saling berdekatan. Kondisi ini sangat menguntungkan karena dapat memaksimalkan keuntungan dan meminimalkan cost baik dari produksi maupun transportasi karena antara lokasi bahan baku dan lokasi pasar saling berdekatan. Hal ini diperkuat dengan hasil analisis R/C rasio dari masing-masing desa pengembang padi organik, dimana R/C rasio untuk Desa Tanah Merah bernilai 1,36, Desa Lubuk Bayas bernilai 1,39, dan Desa Pematang Setrak bernilai 1,48 atau paling tinggi yang artinya lebih efisien dan menguntungkan dibandingkan dengan dua desa sebelumnya. Sementara itu, dari hasil analisis AWOT diperoleh tiga prioritas utama untuk strategi pengembangan padi organik, yaitu (1) mempertahankan kualitas melalui perbaikan kemasan dan sertifikasi beras untuk meningkatkan daya tarik konsumen untuk membeli, (2) melakukan pembinaan dan penyuluhan terhadap masyarakat atau petani mengenai konversi lahan dan manfaat beras organik, serta (3) memperluas jaringan dan jangkauan pasar., North Sumatra Province has fertile soil for rice cultivation and potential area for developing organic agriculture. Organic rice products have been developed in the province and have received certification from the Organic Quality Assurance (PAMOR). One spot of the organic rice centers in the province is Serdang Bedagai Regency, located in Perbaungan District (in Lubuk Bayas Village and Tanah Merah Village) and in Teluk Mengkudu District (in Pematang Setrak Village). Although implementing organic rice development in the Serdang Bedagai Regency is entirely prospective, however, it has not yet been supported by a research on organic rice agribusiness, especially those associated with regional (spatial) aspects. This study aims to develop a strategy for developing organic rice in the Serdang Bedagai Regency which also looks at the spatial pattern. The method to answer these objectives includes identifying existing organic rice paddy fields through satellite imagery and ANN analysis to see spatial patterns between agribusiness subsystems, then R/C ratio analysis of farming and AWOT analysis to obtain strategic priorities to develop

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.
