Judul: Rancang Bangun Sistem Pendataan Perikanan Tangkap di Kabupaten Sukabumi, Jawa Barat
Abstrak: Good data collection system is important factor in gaining an efficiency that will create an advantage, especially on fisheries data collection. However, fisheries data collection system in Sukabumi is still very simple and done with the manual system. Seeing the potential of Sukabumi fisheries, we need a system design of effective and efficient data collection in order to improve the performance of any part of the ports in Sukabumi. This study aimed to design a system of web-based fisheries database that can be accessed by any institution in Sukabumi and can be used as consideration in decision-making on fishery policy in Sukabumi. The analysis used is the development of a system that aims to produce an effective operating system based on the information needs of the user by using My SQL (Structure Query Language) and PHP (Hypertext Processor). The results of the analysis have shown that the fisheries data collection system can be identified on data of Sukabumi into 10 parts, production, ports, fishing, boats, type of boats, fishing gear, kind of catch, KUB (Joint Business Group), fisheries enterprise and managing user menu. The web-based application data management process is expected to be more structured and more efficient so as to support the fishing activities in Sukabumi.

Judul: Design of Fishing Port System Information (Case Study of Cilacap Fishing Port)
Abstrak: The objective of the research is to design fishing port information system which is friendly to fishermen. Such system is expected to promote efficiency of capture fishery and management of Cilacap fishing port. The activities of research were field surveys, system analysis, system design development, computer programming, system testing, and necessary improvement of the system. Primary data were obtained from field observations and interviews with stakeholders. Secondary data were collected from Cilacap Fisheries Agency, statistical report from Cilacap fishing port authority and Central Province Fisheries Agency. The research was conducted from December 2004 to December 2006. Data analysis was carried out with system approach; the information system was designed to be more user friendly, especially for fishermen. Types of information available in the system are: (1) service available in the fishing port, (2) fishery activities at the fishing port, (3) general condition of Cilacap Regency, and (4) general condition of fish resources and seasonal pattern. In general, this information system applicable to other fishing port. The data base is structured into four categories, i.e. catch, port facilities, environment and oceanography data, fishing vessels and fisherman. These four categories are explained in several supporting files. The system uses the ASP program, there are two displays: input and output. The input is provided for system administrator and the output while provide information for the users. The submenus available to the users are Cilacap fishing port, fishing information, Cilacap Regency and other submenu on fish resources.

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.
