Judul: Analisis Risiko Usaha Perikanan Tangkap Skala Kecil di Palabuhanratu
Abstrak: The number of Indonesia’s small scale fishing is huge and growing up, however commonly fisherman’s welfare still below the poverty line. Capital resistance access is one of restrictively factor to the condition. Besides banking system put fisheries capturer activity as a high risk and indeterminancy. Based on the situation we intend to do research for describing the risk of comprehensive small scale fisheries capturer in Palabuhanratu, include in offering a solution. The aim can be approach by several activity, (1) identify and address the risk of fisheries capturer activity, (2) calculate the risk and impact of production, price and income, (3) calculate the fisherman’s attitude about the risk, (4) design an easy solution for the fisherman to get the business capital. The research was held in October 2006 until March 2007 in Palabuhanratu District, Regency of Sukabumi, the data collected and analyzed using descriptive method, deviation standard, variation coefficient, PRT and SWOT. Based on the result we know that risk in small scale fisheries capturer activity generally consist of (1) loose or damage in piscatorial facilities, (2) ineffective of capturing operation and, (3) threat of fisherman safety. Palabuhanratu fisherman tend the act by not to take the risk (risk averter). There are 3 priority solutions for the problem regarding capital accessibility. There are (1) implementing flexible loan regulation which is still in prudential, (2) create a law of capital strengthening, (3) enacting financing scheme suitable with fisheries capturer characteristics

Judul: Penilaian Unit Penangkapan Pancing Rumpon di Palabuhanratu, Kabupaten Sukabumi, Jawa Barat
Abstrak: Tuna total production with rod fishing increase 0.73% in 2011, and total of rod fishing unit increase 1.55% in the same time. Technical and economical analysis must be done for we know how the feasibility of rod fishing unit’s business. The objective of the research is to describe the rod fishing unit, to calculate the benefit, and the investment of rod fishing unit’s business in Palabuhanratu waters. The research is case study of rod fishing unit’s business. Data analysis used description, technical and financial analysis. There are four types of rod fishing, those are troll fishing, pancing jerigen, pancing layanglayang and hand line. The rod fishing is not difficult in operation. Business of the rod fishing unit can give a profit Rp 67,245,500.00 and payback period is 4.2 years. The value of NPV is more than 0 (zero), Net B/C is more than 1 and IRR is more than value of interest rate. The business of rod fishing unit is not sensitive to the fuel’s price increasing. The decision makers can help the fishermen to improve their capital from finance institution, and do the detail technical analysis about rod fishing unit operation and its influence to stock equilibrium

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.
