Judul: Analisis Kelayakan Usaha Pertanian Terpadu Kambing Peranakan Etawa-Padi Semi Organik (Studi Kasus: PT Wirayasa Mandiri, Desa Wanasari, Kecamatan Bangodua, Kabupaten Indramayu, Jawa Barat)
Abstrak: Goat is the cattle with second highest productivity in Indonesia. Based on its productivity, goat is divided into beef goat and diary goat. PT Wirayasa Mandiri is the one of company that is breeding and growing double purpose diary goat resulted by excellent species of Etawa Crossbreed goat with integrated agriculture. Instead to produce goat milk, PT Wirayasa Mandiri also utilize waste resulted from the cattle as organic fertilizer and pesticide for semi organic paddy plantation. The aims of this research are understanding the feasibility of business by financial and non financial aspect analysis in husbandary of diary goat and semy organic paddy plantation with three scenarios. Non financial aspect which are used in this research are market aspect, tecnical, law and management, socioeconomic and culture, and also environment aspect. Based on value of investment criteria, integrated farming (scenario III) with harvest system by machine get the highest value of investment criteria, which are NPV (Rp796 376 365), Net B/C 20 (3.06), IRR (47.96 percent), and Payback Period (3 years and 4 months). Based on switching value analysis, increasing of feed price on scenario III is most sensitive with maximum limit of increasing value that is 4.27 percent.

Judul: : Kelayakan Usaha Penggemukan Kambing Jawa Randu pada Kelompok Tani Simpay Tampomas Desa Cibeureum Wetan Kabupaten Sumedang
Abstrak: In run businesses, fattening goat Jawa Randu, farmer groups simpay tampomas not based on knowledge, the group just rely on the experience and intuition course. The study is to analyze the feasibility of business fattening goatie java randu in the farmers simpay tampomas. The analysis used is a method of analysis non financial sensitivity of financial analysis and analysis. The aspect of non financial analyze about aspects of the market and marketing- the technical aspects, the aspect of management, legal aspects and social aspect. Financial analysis counting analysis based on npv, eligibility criteria irr, net b / c and payback period. Analysis of sensitivity of counting the influence of occurring price change against the feasibility of undertaking of fattening this goat. Based on the result of reckoning analysis of eligibility criteria business through investment produce npv 118 439 681, as much as rp net / c to b 1.67 irr by 26% and 4 years payback a period of three months. Thus the business of fattening done by farmer groups simpay tampomas worthy to be executed financially. Analysis of switching value to a decrease in the selling price of goats are worth 5.67 % and price was going to a goat as much as 10.72%.

Judul: Transisi Fasa Materi Hadronik ke Materi Kuark pada Inti Bintang Neutron.
Abstrak: Bintang neutron terdiri dari beberapa lapisan yang disusun oleh materi nuklir yang berbeda dengan kerapatan yang semakin tinggi ketika mendekati pusat bintang. Inti luar bintang neutron disusun oleh materi hadronik (nukleon, lepton, dan hyperon), sedangkan inti dalam bintang neutron disusun oleh kuark-kuark bebas (up, down, strange) yang saling berinteraksi. Tujuan penelitian ini adalah mempelajari bagaimana transisi dari inti luar ke inti dalam bintang neutron dengan menggunakan pendekatan RMF (Relativistic Mean Field) untuk materi hadronik dan CIDDM (Confined Isospin Density Dependent Mass) untuk materi kuark. Tekanan transisi diperoleh ketika potensial kimia barion materi hadronik dan materi kuark bernilai sama. Nilai tekanan transisi dengan parameter SU6-TM1 sekitar 87 MeV/fm3 dan diperoleh massa maksimum bintang neutron yaitu 1.92M dengan jari-jari sekitar 8.62 km. Nilai tekanan transisi dengan parameter SU6-G2 sekitar 53 MeV/fm3 dan massa maksimum bintang neutron yaitu 1.88M dengan jari-jari sekitar 8.16 km. Jenis transisi fasa adalah orde satu ditandai dengan diskontinuitas dalam kerapatan energi (adanya mixed phase). Parameter-parameter pada model nuklir yang digunakan menyebabkan perbedaan kekakuan persamaan keadaan (EOS) dari materi hadronik dan materi kuark sehingga nilai tekanan transisi dari fasa hadronik ke fasa kuark juga berbeda.
