Abstrak: Indonesia is an archipelago with ownership of an area of 5,800,000 km2 of territorial waters is divided into territorial waters covering an area of 300,000 km ², the waters of the archipelago area of 2,800,000 km ² and the Indonesian Exclusive Economic Zone (ZEEI) covering an area of 2,700,000 km ² (Directorate General of Fisheries 1994). Water area is so vast that a comparative advantage of Indonesia to develop the fisheries sector as part of efforts to enhance the success of both the production of farmed fish and fish catch. Indonesian territorial waters support a very large extent, is able to provide the potential for fisheries production reached 65 million tons per year which comes from aquaculture potential reach of 57.7 million tons per year and the potential for capture fisheries (marine and public waters) which reached 1.2 million tons per year. Currently this potential new used only 6 million tons or 9.2 percent of the total potential ada1. Viewed from the side of potential economic value, the value of production is estimated to reach U.S. $ 78.1 billion per year, consisting of U.S. $ 16.2 billion fishery and $ 61.9 billion of U.S. aquaculture (Sukandar, 2008). Based on previous data known that aquaculture provides the greatest potential in the development of the fisheries sector in Indonesia. This is because many of its products aquaculture fisheries can be developed and in try in the business activities. Currently there are 10 types of aquaculture commodities that has been developed in addition to increasing his request, but also because of technology and culture is more advanced information that supports the successful cultivation. In the research objectives to be achieved is to analyze value added and competitiveness which includes comparative and competitive advantages in Bogor Regency sangkuriang catfish. The methods used include purposive sampling in the determination of the respondent, the method of data analysis using Hayami method for the analysis of value added and competitiveness using Analysis Policy Matrix (PAM). These results indicate that agribusiness catfish sangkuriang in Bogor Regency has added value, as can been seen from the value-added industry in the processing of processed catfish nuggets of Rp 1,316 per kilogram of raw material, the value of R / C 1,300 and BEP value of Rp 642 073, 52. Whereas for the shredded meat processing value-added of Rp 830 per kg of raw material, the value of R / C 1.128 and BEP value of Rp 1,294,091.45. While the views of the competitiveness of the Bogor Regency has good competitiveness sangkuriang comparative catfish with catfish farming sangkuriang 3 centers namely district Ciomas, Gadog and Parung, competitive and visible from the DRC value for the three areas that are less than one (Kec. Ciomas of 0.63, the district . Gadog of 0.75, and the district. Parung of 0.58.

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.
