Abstrak: The purpose of this study was (1). analyze the feasibility of catfish farming in dry land in the district of Gunungkidul Yogyakarta Province, (2). analyze the potential of catfish farming in ponds tarp on dry land., (3) develop alternative business development in the district of Gunungkidul Yogyakarta Province. The method used in this thesis is descriptive method that focuses on technical aspects and business development aspects of aquaculture, as well as a SWOT analysis. Based on financial analysis, the pond area 12-16 m2 level cultivators consumption catfish prices average per kilogram Rp. 1,0394,- production resulting catfish consumption 3,642.95 (equivalent to 453.88 kg of catfish), earnings per cultivation cycle Rp. 1,557,874, - or Rp. 4,673,620,- within one year of cultivation period, net profit per year of Rp. 832,668,- or an average of Rp. 277,556,- per cycle of cultivation, production volume BEP at 344.54 kgs, or BEP at a price of Rp. 7,890,-/kg, Gross Value B/C Ratio of 1.22 based on the criteria and payback period (PBP) obtained the results 3.81; the pond area 20-25 m2 catfish prices average consumption per kilogram farmer level Rp. 10,673,- the resulting 7,180 production catfish consumption (equivalent to 868 kg of catfish), earnings per cultivation cycle Rp. 3,065,114,- or Rp. 9,195,341,- within one year of cultivation period, net profit per year of Rp. 2,248,907,- or an average of Rp749,635,- per cycle of cultivation, production volume BEP at 571.13 pounds, or BEP obtained a price of Rp 7,020,- / kg, Gross Value B/C Ratio of 1.32 and based on the payback period criteria (PBP) obtained results of 2.97 years; the pond area 30-45 m2, level cultivators consumption catfish prices average per kilogram Rp. 1,0291,- production generated 1,0661.01 catfish consumption (equivalent to 1,242.06 kg catfish), earnings per cultivation cycle Rp. 4,268,777, - or Rp.12,806,333,- within one year of cultivation period, net profit per year of Rp. 3,245,323,- or an average of Rp 1,081,774,- per cycle of cultivation, production volume BEP at 807.99 kgs, or BEP obtained at the price of Rp. 6,695,- / kg, Gross Value B/C Ratio 1.34, and based on the criteria of payback period (PBP) obtained results of 2.64 years. To maximize revenue catfish farmers, a strategy that has been formulated on the SWOT analysis needs to be implemented on the pattern of farmers by increasing the amount of effort and extensive farming ponds and develop, implement ways of maintaining and good cultivating, as well as expand the reach of markets ranging from individual consumers, traditional market and a restaurant to the modern retail market to increase profits catfish farmers in dry land in the district of Gunungkidul.

Judul: Dumbo Catfish Hatchery and Enlargement Integration Business Planning at Ciseeng Sub-district, Bogor Regency
Abstrak: Catfish is one of nine leading commodity in the aquaculture sector, whose production increased annually (KKP 2013). As for some catfish production centers which play an important role in meeting demand for catfish namely West Java, East Java, Central Java, Yogyakarta, North Sumatra, West Sumatra, South Sumatra, Lampung, Riau and Riau Islands West Java occupying the highest position as a major producer of catfish (KKP 2013). Dinas Perikanan Provinsi Jawa Barat (2012) states that the Bogor Regency is the center of production centers which accounted for 27.4% of total production in West Java. The center for integrated aquaculture catfish either seed or in the form of catfish consumption in Sub Ciseeng which is one of the Minapolitan (Dinas Peternakan dan Perikanan Kabupaten Bogor, 2013). Seed production occurring in the Sub Ciseeng which began to decline due to the risks experienced in the seeding sector more than 50% compared to the considerable enlargement of the sector reached 35% so that the seed input certainty for enlargement sector decreased. To overcome this, catfish farming need to be developed properly so that the certainty of guaranteed input for enlargement and the need for consumers catfish consumption can be met. The development of the cultivation of catfish one of which can be done by doing the integration between hatchery and rearing sectors. In the process of business development that has integrated catfish is important to do the analysis of business planning on sustainable Jumbo’s Pokdakan because the catfish farming process is influenced by a variety of things ranging from rising feed prices, changes in output prices, and more. Business planning is based on selection of a combination of the scenarios that generate optimum NPV. There are five scenarios that will be analyzed is the effort that starts from the hatchery broodstock to seed 12 cm (first scenario), hatchery operations were started from seed breeders to 1-2 cm and 12 cm (second scenario), hatchery operations were started from seed 1- 2 cm to 12 cm (third scenario), enlargement efforts started from seed 12 cm (fourth scenario), and business enlargement started from seed 1-2 cm (fifth scenario). Based on these things, the purpose of this study was to analyze the feasibility of nonfinancial views of market aspects, technical aspects, management aspects, social aspects, economic aspects and environmental aspects The second objective analyzes of financial feasibility seen from the investment criteria Net Present Value (NPV), Net B / C, Internal Rate of Return (IRR), and Discounted Payback Period (DPP) on five scenarios and combinations of catfish farming can produce optimum conditions. The third objective is to analyze the sensitivity of African catfish fishing effort and drafted a business development subsequent to the integration of African catfish farming that started from seeding to enlargement. This research uses Test feasibility and Zero-one Integer Linear Programming. Results of the analysis showed hatchery operations has actually been decent, but the effort enlargement is more profitable than hatchery operations. From the non-financial aspects of which consists of social, technical, management, economics and the environment before integrated catfish farming is feasible to run but not

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.
