Judul: Design for management of capture fisheries base on fishing vessel registration system in Aceh Province
Abstrak: In Indonesia fishing vessel registration is handled by two different institutions, namely the ministry of transportation (at the province/district level is represented by the Harbor Master / Transportation Agency) and the ministry of maritime affairs and fisheries (at the province/district level is represented by the Marine Fisheries Agency). In general, the implementation of these activities often markdowns conducting, high cost, taking long time document process, unregistered in Jakarta, and uncomputerize. Research on the fishing vessels registration is very important to anticipate the markdown practices and high costs. The purpose of this study is to design the management of capture fisheries base on integrated fishing vessels registration system, by computerized data base system as well as integration between the agencies involved in the registration. The research conducted from September 2008 until December 2009 in several district in Aceh Province. The method in this study were (1) collecting Primary data directly in the field and verificating the vessels especially under 30 GT, (2) using systems analysis and institutional analysis for both involved agency (3) using HUBLA and Nomura formula for the Gross Tonnage (GT) calculation of vessel. The conclusion of this study were: (1) the design of integrated management of fishing vessel registration was proved can eliminate the practice of markdowns effectively, (2) computerized data base system was proved can speed up the process of vessel document publication,(3) To facilitate the re-registration, system was supported by on line fishing vessel registration information system (SIRKI), so stake holder can get information i.e : the vessel process, ownership, dimension and fishing gear, (4) The integrated fishing vessel registration can be used as a baseline for the capture fisheries management.

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: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
