Judul: Studi Difusi Inovasi System of Rice Intensification (SRI) di Kabupaten Tasikmalaya (Kasus di Dusun Muhara Desa Banjarsari Kecamatan Sukaresik Provinsi Jawa Barat)
Abstrak: So far, research on most of the SRI innovation emphasizes the technology aspect. Meanwhile, research regarding the introduction of agricultural innovations to the farmers in Indonesia more emphasis on adoption of innovation at the level of individual farmers. This study aimed to determine (1) SRI innovation distribution maps in Tasikmalaya District in the Muhara Hamlet especially, since introducted until the research conducted, (2) SRI innovation diffusion process, particularly innovativeness, the pattern of adopter categories that occurred in the community and the rate of paddy SRI innovation adoption and the factors that influence it, and (3) whether there is any problem in implementing innovative programs SRI in Tasikmalaya District, particularly in the hamlet of cases and the factors influencing it. This study found that the majority of those classified as low in productivity, income level, the rate of introduction of SRI innovation from the mass media, the level of participation of farmers following the extension, nonformal education level and household level stratum of farmers, while classified as medium in terms of level complexity, triability level, observability level, the level of adherence to conventional cultivation farmers, farmers 'level of integration, the level of diversity of SRI innovation counseling methods, the level of formal education, communication and behavior patterns as well as high in SRI type of innovation decision making, the level of farmer’s needs for innovation SRI and adoption rate of SRI innovation. SRI has been running from 2006, in Hamlet Muhara but still found some problems that arise. The problem is not locally available organic fertilizers, pest control is still low and the perceived marketing SRI paddy farmers still do not provide benefits for not providing the expected added value. Therefor, need assistance in the form of supplying the holding of a couple holding livestock in the form of goats, chickens, guinea pigs, ducks and other in a revolving system from one farmer to another farmer, induction of pest control experts to provide training how to cope with pests by using the method of Participatory Rural Appraisal (PRA) and the importance of awareness about organic agriculture, there is a willingness from the Department of Agriculture Tasikmalaya to make efforts so that SRI rice marketing can provide significant benefits for farmers by establishing agreements with distributors who can market the SRI paddy farms in Muhara with competitive prices and also provide training to farmers on organic agriculture certification standards set

Judul: Penerapan teknologi System of Rice Intensification di Desa Margahayu Kabupaten Tasikmalaya
Abstrak: Seiring bertambahnya populasi penduduk Indonesia, permintaan beras sebagai makanan pokok sehari-hari sebagian besar penduduk Indonesia terus meningkat. Namun, laju pertumbuhan produksi padi nasional tidak dapat mengimbangi laju pertumbuhan penduduk. Di sisi lain, kenaikan produksi padi nasional tidak diikuti dengan kenaikan produksi padi di Jawa Barat sebagai sentra produksi padi Indonesia. Laju pertumbuhan produksi di Kabupaten Tasikmalaya dan Kecamatan Manonjaya terus menurun. Berbagai usaha untuk meningkatkan produksi dan mengurangi konsumsi beras telah dilakukan, salah satunya melalui intensifikasi. Upaya ini masih mampu dijadikan andalan agar target peningkatan produksi beras nasional hingga dua juta ton pada tahun 2007 akan tercapai. Salah satu metode intensifikasi budidaya padi baru adalah system of rice intensification (SRI). Suatu teknologi baru dapat diterapkan oleh petani secara massal jika memang terbukti dapat meningkatkan hasil produksi dan pendapatan petani. Sehingga, perlu dilakukan evaluasi terhadap penerapan teknologi SRI. Dengan demikian dapat diketahui apakah teknologi ini dapat diterapkan secara nasional. Tujuan penelitian ini adalah mengevaluasi penerapan teknologi SRI di Desa Margahayu, mengidentifikasi faktor-faktor yang mempengaruhi penerapan teknologi SRI, menganalisis pendapatan dan efsiensi penggunaan faktor-faktor produksi usahatani padi SRI. Penelitian dilakukan di Desa Margahayu Kecamatan Manonjaya Kabupaten Tasikmalaya Jawa Barat pada bulan April hingga Mei 2007. Jenis data yang digunakan adalah data primer dan data sekunder. Data primer diperoleh melalui wawancara langsung dengan petani yang dipandu kuesioner. Data sekunder diperoleh dari berbagai sumber terkait seperti Departemen Pertanian, Dinas Pertanian Kabupaten Tasikmalaya, Badan Penyuluh Pertanian Kecamatan Manonjaya, Kelurahan Desa Margahayu dan media massa. Analisis data yang digunakan dalam penelitian ini adalah analisis kualitatif dan kuantitatif. Analisis kualitatif meliputi keadaan umum usahatani padi dan evaluasi penerapan teknologi SRI, sedangkan analisis kuantitatif berupa analisis pendapatan usahatani, analisis R/C rasio, analisis penggunaan faktor-faktor produksi serta efisiensi faktor produksi.

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.
