Judul: Strategi Kebijakan Penanggulangan Illegal, Unreported, dan Unregulated (IUU) Fishing di Laut Arafura
Abstrak: One of the main problems in developing marine and fishery sector in Indonesia in the great number of irresponsible fishing practices, internationally knouwn as illegal, unreported and unregulated (IUU) fishing. IUU-Fishing is a serious threat to the responsible management of fish resources and an obstacle to the development of continued cact fishery. In this, there are 335 prawn trawlers above 30 GT as licensed by Marine and Fishery Departement in operation in Arafura Sea. Others prawn also has took the same activity but does not with licensed. Thre result of identifying fishing violations in Arafura Sea ia as follows : many fishing ships were not equipped with a fishing license, many ship did not obey the articles in the license, many ships were not eqipped with veseels monitoring sistem (VMS), and there were pair trawl. Unreported fishing happened because many fishers unload and sold the is cacth at sea (transhipment). Policy strategy in over coming IUU-Fishing by the Papua Province goverment which is formulated using SWOT analysis is to increase the role of government investigating officers from Marine and Fishery Departement through the establishment of fishery yudicial institution, to provide a surveillance ship, to build a supporting fishery port, to increase fund allocation to the supervisory activity, to improve coordination to control crimes at sea, and recruit more fishery personnel.

Judul: The shrimp fisheries management options of the Arafura Sea
Abstrak: Arafura Sea is the one of the 9 fishing grounds in Indonesia for shrimp fishing which the total area is estimated 150.000 km2. The total fish stock is estimated to be 1.076.890 tons/year and the demersal fish stock inlcuding shrimp is 145.830 tons/year. The shrimp fisheries condition at Arafura Sea is presumed to be over fishing and overcapacity due to ineffective of current management, lack of law enforcement capabilities, and lack of fishermen concern of the sustainable principles. The main objective of the dissertation is to formulate the shrimp fisheries management options which include vessels number reduction, implementation of quota and seasonal closure. The specific objectives of the dissertation are include: (1) analyze the shrimp fisheries bioeconomic, (2) analyze the actual versus sustainable production trend, (3) measure shrimp fishing capacity and efficiency, (4) formulate the recommendation of the future management options.

Judul: Karakteristik Carboxymethyl Chitosan Dengan Variasi Konsentrasi NaOH
Abstrak: Carboxymethyl chitosan is chitosan derivative product obtained from chemical modification. CMCh were made by alkalization process and carboxymethylation process. Factors that affect CMCh characteristics were excess sodium hydroxide in alkalization process, ratio between chitosan and monochloroacetic acid, and carboxymethylation temperature. The objectives of this research were to study the NaOH effect to CMCh characteristics, to learn process of making CMCh, to set the proper concentration of NaOH, and to analyze CMCh characteristics. CMCh yields were 110.72%-114.22%. CMCh pH value were 3.74-4.31. The optimum NaOH concentration to obtain the best CHCh was 10 M. Percentage of CMCh moisture content was 10.70%-11.42%. Ash content and nitrogen content of CMCh were 0.49%-0.50% and 4.52%-4.81%. CMCh viscousity was 8.25 cps. Percentage of CMCh solubility was 61.61%-91.50%. The different functional groups from chitosan which observed in CMCh were C=O group, CH group from alkene functional group, C−O group, and C−O−C group.
