Judul: Analisis Efisisensi Ekonomi Armada Perikanan Tangkap Kincang di Pelabuhanratu, Kabupaten Sukabumi, Jawa Barat (Pendekatan Data Envelopment Analysis)
Abstrak: Economic efficiency is one of the indicators in the implementation of sustainable fisheries. Analysis of the economic efficiency of fishing fleets is of great importance, especially for policy makers in fisheries management based on sustainability. The research was conducted in Pelabuhanratu, West Java. This research examined the focus of the fishing fleet that is kincang ship. The data used are primary and secondary data. Data Envelopment Analysis (DEA) is used to determine the relative efficiency over time (Type I) and between fishing fleet (Type II). For the relative efficiency between vessels used also 2 scenarios that maximizing output and minimizing input. DEA analysis of Type I shows that the most efficient trajectory occurred in 2009 and 2011 by using revenue as output, and in 2008 with production. DEA results include Type II with all inputs and outputs produce 10 DMU efficient, while the DEA with Type II maximizing output produce 1 DMU efficient and minimizing input produce 2 DMU efficient

Judul: Fisheries Development Analysis of Purse Seine Fisheries Aceh Besar District
Abstrak: Purse seine is one the productive fishing gear for fishing pelagic fishes. Fishing capacity is one the important issue in sustainable fisheries. This study aimed to measure fishing capacity of purse seine in Aceh Besar district, estimated the maximum economic yield (MEY) the targeted pelagic fishes, and formulate management strategies purse seine in the district of Aceh Besar. Fishing capacity was analyzed using the data envelopment analysis (DEA) method based on fishing capacity efficiency of monthly total catch as single output, from September 2009 to August 2010. Fishing vessel was used as decision making unit (DMU). Fixed input consists gross tonnage (GT), engine horse power (HP) and length of webb. Variable input consists number of crew, lamp power (watt), hold capacity (ton), and number of trip. The result showed that fishing capasity, 17 vessels reached optimum (CU=1), and fishing capacity of purse seine was 257 ton/year/unit. Thus bioeconomic analysis of pelagic fishes showed that MEY reached at 3,753.37 ton/year and optimum effort at 8,623 trip/year with total cost Rp 34,992,314,500 year and total revenue Rp 51,643,083,629. Management strategy for purse seine fishery in Aceh Besar district is the development of technology, human resource development and the role of institutions such as institutions laot commander.

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.
