Judul: Sustainable management of capture fishery in Jakarta Waters, DKI Jakarta Province
Abstrak: Jakarta Waters is categorized as fully exploited water areas which its coastal areas accommodate multifunction services. Therefore, it needs precautionary approach to manage fisheries activity and its resource in the location. This is important to sustain the potential resource, provide prosperity to fishermen as well as coastal communities. The general objectives of this study are to arrange the sustainable fishery management in Jakarta Waters, while specific objectives of this study are to evaluate capture fishery management status; to determine optimum allocation of potential fishing gears and fisheries development areas based on potential fishing gears; to analyze the various components affecting to capture fishery activity based on suitable area and to analyze internal and external conditions in order to arrange the strategies for sustainable fishery management in Jakarta Waters. The methods used in this study were system approach, SWOT analysis, Linear Goal Programming (LGP) analysis, analysis of Location Quotients (LQ), Geographic Information System (GIS) analysis, and Analytical Hierarchy Process (AHP) method. The results revealed that the management of capture fishery in Jakarta Waters was categorized as "kurang baik" with the total scores of 2.529 and 2.747 for internal and external factors analysis, matrix IE pointed out that the position of fishery management at growth level which need strategy to do coordination horizontally with the other stakeholders. By using GIS analysis, it was identified that 52,89% of Jakarta Waters can be used for capture fishery, less than 25% can be used for fish farming (cage culture) and less than 15% can be used for seeweed culture. Meanwhile the potential fishing gears to be developed were pelagic danish seine, drift gillnet, boat lift net, set bottom long line, portable trap and muro ami which have the optimum allocation for each fishing gear; 7 units, 98 units, 23 units, 18 units, 8547 units, and 798 units. The potential fishing gears for pelagic danish seine could be developed in Penjaringan and North Seribu Island Districts; drift gillnet could be developed in Cilincing District; boat lift net could be developed in Penjaringan District; set bottom long line could be developed in Penjaringan District; portable trap could be developed in Cilincing and South Seribu Island Districts while muro ami could be developed in Penjaringan and South Seribu Island Districts. The study identified that there are several important strategies to support sustainable capture fishery management, from the first priority to the last are small-scale fishery standardization, integrated management to conserve the ecosystem function, quality product improvement, fishing days opreration management by implementing closed – open seasons, increasing independent fishermen capability, human resources empowerment, extention for fishermen and increasing capture fishery activities supervision. As the first priority, the standardization of small-scale fishery should be stable against changes in the dimension of biology and quite stable against changes in the ecological, economic, social and technological dimension.

Judul: Penapisan Inhibitor Tirosinase pada Empat Spesies Famili Asteraceae Chrysantemum morifolium R, Gerbera jamesonii A, Dahlia rosea Cav, dan Tagetes erecta.
Abstrak: The research was conducted to screen the potency of tyrosinase inhibitor from 4 species of Asteraceae family. The screening was performed on the leaves and flowers of Chrysantemum morifolium R, Gerbera jamesonii A, Dahlia rosea Cav, and Tagetes erecta. The samples were dried and then extracted with nhexane, ethyl acetate, and methanol. The inhibition activity was tested by a microplate reader spectrophotometer in 492 nm. The ethyl acetate extract of D. rosea Cav flower was the most potent tyrosinase inhibitor (IC50 for monophenolase 18.42 μg/mL and for diphenolase 687.79 μg/mL) compared with the other Asteraceae species. The most active essential oils as inhibitor of tyrosinase was obtained from T. erecta flower (IC50 for monophenolase 1882.62 μg/mL and for diphenolase 1884.33 μg/mL). Positive control used was kojic acid with IC50 value of 11.02 μg/mL for monophenolase and 84.19 μg/mL for diphenolase. Fractionation of the extract by preparative thin layer chromatography with chloroform as mobile phase gave 12 fractions. The most active fraction had IC50 of 5.55 μg/mL for monophenolase and 109.96 μg/mL for diphenolase, and was identified as flavonoid.
