Judul: Analisis kapasitas penangkapan (fishing capacity) pada perikanan purse seine di Kabupaten Aceh Timur Provinsi Nanggroe Aceh Darussalam
Abstrak: Perhitungan kapasitas penangkapan ikan menjadi isu penting pada upaya pengelolaan perikanan yang berkelanjutan. The Code of Conduct for Responsible Fisheries (CCRF) yang disusun oleh FAO (1995) mengajak kepada seluruh negara untuk mencegah lebih tangkap (overfishing) dan menghindari kelebihan kapasitas penangkapan ikan. Kabupaten Aceh Timur menjadi pangkalan perikanan purse seine dengan aktifitas upaya penangkapan tertinggi di Provinsi Nanggroe Aceh Darussalam. Kegiatan perikanan purse seine di Kabupaten Aceh Timur berpusat di Pelabuhan Perikanan Pantai (PPP) Idi Rayeuk. Purse seine merupakan alat tangkap yang mampu menangkap ikan-ikan pelagis dalam jumlah yang besar dalam sekali beroperasi. Oleh sebab itu peningkatan upaya penangkapan alat tangkap ini diduga dapat mempengaruhi stok ikan-ikan pelagis di perairan tersebut. Kajian kapasitas penangkapan di Kabupaten Aceh Timur belum pernah dilakukan, sehingga sulit untuk merumuskan program pengelolaan sumberdaya ikan yang berkelanjutan. Oleh karenanya sangat penting untuk memperoleh informasi tersebut melalui penelitian tentang “analisis kapasitas penangkapan (fishing capacity) pada perikanan purse seine di Kabupaten Aceh Timur Provinsi Nanggroe Aceh Darussalam”. Secara umum penelitian ini bertujuan untuk mengukur kapasitas penangkapan purse seine di Kabupaten Aceh Timur dan mengestimasi nilai maximum sustainable yield (MSY) ikan pelagis yang menjadi target penangkapan dengan purse seine.

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.
