Judul: Analisis keuntungan dan peluang penggunaan alat tangkap legal dan ilegal di kabupaten Indramayu
Abstrak: Nearly half the supply of sea fish commodity in West Java province comes from Indramayu district, but its resource sustainability is threatened by destructive fishing gear. These problems have prompted the government to establish the type of fishing gear regulations, so it appears the group of legal fishing gear (LFG) and illegal fishing gear (IFG) in the fishing industry. The purpose of this thesis research is to estimate and test the difference's profits from the use of LFG and IFG, and estimate the factors that affect fishing The Use of Legal and Illegal Fishing Gear at District Indramayu. Under the Direction of YUSMAN SYAUKAT and DEDI BUDIMAN HAKIM. probabilities to be IFG users persistently and alternately and LFG users persistently. The research objective is achieved by using primary data obtained through a survey. The difference's profits from IFG and LFG were tested with nonparametric statistical methods, and an ordered logit econometric approach used to meet the last objectives. The results are concluded, (1) the profits from using IFG greater than 113 560 rupiahs from LFG on boat size under 5 gear tonnage (GT), contrary to the boat size 60-10 GT, the profit from using LFG greater than 197 900 rupiahs from IFG, (2) there are significant differences between IFG and LFG profits in the fishermen who conduct transactions on fish auction (FA) and use the boat size below 5 GT, and the fishermen who make transactions outside of FA and using a boat sized 60-10 GT, and third, fishing probabilities to use IFG persistently and alternately and LFG users persistently are influenced by the profit per trip IFG, the type of market (FA or outside FA), off-fishing income, education level, and level of enforcement of fisheries regulations. The increase in IFG profits, off-fishing incomes and levels of enforcement of fisheries regulations can increase the probabilities of the use of IFG persistently and alternately. Conversely, education level and the transaction in the FA can reduce the probabilities of the use of IFG, otherwise increase the probabilities of the use of LFG

Judul: Economic Analysis of Sustainable Management of Fisheries Effort in Indramayu Regency
Abstrak: As an archipelagic country, Indonesia has territorial water at 5,8 million km2 Method of this research are biological analysis, bio-economical model, economic interest analysis, economic intensity analysis, and strategic analysis with use analytical hierarchy process (AHP). Fish resources with potential and become main products of fishermen in Indramayu Regency Indramayu are manyung, tenggiri, peperek, kembung, and tongkol. The production of fifth fish species about 85,6 % from fish production total in territorial water of Indramayu Regency. Maximum stock capacities (MSY) of manyung, tenggiri, peperek, kembung, dan tongkol in territorial water of Indramayu Regency each are 1291,37 ton/year, 1120,70 ton/year, 4227,93 ton/year, 1135,76 ton/year, and 5343,58 ton/year. Maximum economic yield (MEY) of manyung, tenggiri, peperek, kembung, and tongkol in territorial water of Indramayu Regency each are Rp 16.471.401.174/tahun, Rp 31.745.619.591/tahun, Rp 54.907.433.923/tahun, Rp 9.911.840.550/tahun, and Rp 42.547.409.047/tahun. consisted about 17.504 islands and coastal line more 81.000 km with various of fish resource. According to DPK of Indramayu Regency (2010a), the production of sea fishery in Regency of Indramayu is stable at 2009 reaching 108.554,6 ton with value about Rp 1.383.687.650.000. That production must influence stock capacities of fish resources in fishing ground, so that its exploiting require to be controlled, inclusive maximum economic yield (MEY). The aim of the research to analyse stock capacities and maximum economic yield of fisheries resources, to analyse sustainability of fisheries effort, and to formulate the development strategic of sustainable economic based on fisheries effort in Indramayu Regency. Drift gillnet (JIH), set gillnet (JIT), payang, bottom long line, handline, dan shrimp gillnet (JK) can be laboured on an ongoing basis in Indramayu Regency. Economi interest of drift gillnet (JIH), set gillnet (JIT), payang, bottom long line, handline, dan shrimp gillnet (JK) each are Rp1.029.134.326, Rp 579.915.247, Rp 992.640.822, Rp 263.338.992, Rp 56.725.341, dan Rp 76.184.501. Return of return of drift gillnet (JIH), set gillnet (JIT), payang, bottom long line, handline, dan shrimp gillnet (JK) each are 42,01 %, 31,35 %, 56,72 %, 58,52 %, 66,74 %, dan 43,53 %. Development strategic of sustainable economic based on fisheries effort in Indramayu Regency from priority most important to less be important are ; (a) Repair of management of fisheries effort (RK = 0,255, II = 0,05), (b) Construction of human resources of fisheries sector (RK = 0,230, II = 0,05), (c) Development of capitalization cooperation (RK = 0,193, II = 0,05), (d) Development of scale small fisheries ( RK = 0,186, II = 0,05), and (e) Development of supporting units of fisheries effort (RK = 0,136, II = 0,05).

Judul: Hydrothermal Synthesis of Biphasic Calcium Posphate
Abstrak: Biphasio calsium phosphate (BCP), which was a mixture of hydroxypatite (HA) and tricalcium phosphate (TCP), was synthesized by hydrothermal method followed by sintering process. Hydroxyapatite was produced by using natural calcium source CaO from hen's eggshell and (NH4)2HPO4 as phosphate souce, other hydroxyapatite sample was produce by using synthetic calcium source Ca(OH) and H3PO4 as phosphate source.
