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: Development of strategy for financing capture fisheries business in Tegal city, Central Java Province
Abstrak: Currently there are approximately 49,8 million small and medium scale businesses in Indonesia, and yet from that figures only 13 % of small scale businesses including fisheries business are able to have access to banking institution, while the rest 87 % are still relied on their owned capital. The weak access to credit and financing also happen in Tegal city, Central Java Province eventough Tegal is considered as one of the fisheries activities center in the country. This research aims to analyze feasibility of capture fisheries business, important production factors in capture fisheries operation, financing components interaction, existing condition of financing to capture fisheries business , and determine priority strategy to develop financing to capture fisheries business in Tegal city, Central Java Province. This research utilizes financial analysis methods, SEM, SWOT and AHP. From the type of fishing gears which are mostly used by fishermen in Tegal, jaring arad, cantrang, gillnet, purse seine and pancing layangan are those considered feasible to be developed. Gillnet monofilamen and jaring rampus are considered not feasible due to their Net B/C ratios are 1,00 and 1,00 respectively ( Standard > 1 ), and IRR are 4,38 % and 3,09 % respectively ( Standard > 6,25 ). Important production factors in fish catching operation for each fishing gear are as follows : (a) jaring arad, are : length of fishing net and stocks of fresh water, (b) cantrang, are: gasoline stocks and ice block stocks, (c) gillnet monofilamen, is length of fishing net, (d) gillnet, are length of fishing net, days of trip, gasoline stocks, ice block stocks, vessel crews, fresh water stock and supplies, (e) jaring rampus, are : length of fishing net, gasoline stocks, ice block stocks and vessel crews, (f) purse seine, are : gasoline stocks, (g) pancing layangan, are : gasoline stocks. The components which are significantly interacted ( p < 0,05 ) in fisheries financing are a : (a) banking institution, consist of general bank ( Bank Umum ) and local government banks (BPD), (b) government institutions, consist of Ministry of Marine Affairs and Fisheries of Republic of Indonesia (KKP RI), (c) capture fisheries business performance, consist of Net B/C, IRR and ROI ratios, (d) political policies, consist of KKPE, KUR and BPLM, and (e) financing performance, consist of amount of credit/ financing given. Existing condition of financing to capture fisheries business in Tegal are now in grow/stability condition (quadran V), with internal factors total score 2,61 ( adequate) and external factors score 2,47 (adequate) , so that still feasible to obtain financing support. Policy startegy which can be developed and becoming financing solution for capture fisheries business in Tegal (based on priority) (inconsistency ratio 0,05) are : improvement of management and performance of capture fisheries business, collateral alocation for credit with lower interest rate, improvement of credit commitment and sanction enforcement to the violator , widely socialization of credit policy to fishermen in order to enhance their understanding on credit and financing, jointly liable in financing urgently needed supplies, improvement of fishermen skill and self-sufficiency of fishing gear .

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.
