Judul: Studi kelayakan pendirian industri tepung dan biskuit ikan lele dumbo (Clarias gariepinus)
Abstrak: African catfish (Clarias gariepinus) is one of the popular fishes that cultivated in Indonesia. It contributes to the fulfilment of people nutrition need. African catfish can be processed into flour which can be further processed in to a variety of foods, including biscuits. The fish biscuits can be used as an alternative food to improve nutrition for the poor in Indonesia. The purpose of the study is to analyze the feasibility of an African catfish (Clarias gariepinus) flour and biscuit industry. The scope of the research includes a feasibility on the aspects of market and marketing, technology, management and organization, environment, legal, and finance. The potential markets of the fish biscuits are infants and toddlers having nutritional problems and disaster victim children. The targeted market of the fish biscuit requires is 8.653 children per year. The products can be delivered in two form: biscuits and mixed flour. This is equivalent to 3.115.080 biscuit chips per year and the mixed flour of 7.200 kg per year. The factory is located in Bogor and the production capacity is 3.120.000 pieces of biscuits per year and 7.800 kg of mixed flour. The total investment needed is Rp 884.335.000, including investment in fixed assets (Rp 687.775.000), and working capital (Rp 196.650.000). The NPV of this business is Rp 2.176.702.231. The IRR value is 61%. The net B/C ratio is 3. The payback period is 2 years and 1 month. These results shows that the catfish biscuit industry is feasible. The sensitivity analysis shows that business is still feasible under the condition of 30% price increase of raw materials and utilities and of 20% sales price decrease.

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.
