Judul: Analisis bioekonomi pengusahaan sumberdaya ikan lemuru ( Sardinella longiceps) di Perairan Selat Bali
Abstrak: Pemilihan Selat Bali sebagai tempat penelitian didasarkan atas indikasi pernah terjadinya biological overfishing dalam pengusahaan sumberdaya perikanan lemuru (Sardinella longiceps) sebagaimana dilaporkan oleh Sujastani dan Nurhakim (1982). Penelitian ini merupakan survei tentang aspek biologi dan ekonomi yang memnpengaruhi perikanan tangkap, khususnya dalam kegiatan penangkapan ikan lemuru (Sardinella longiceps) di Perairan Selat Bali, dengan tujuan optimalisasi pengusahaan sumberdaya secara lestari dan berkelanjutan. Data yang digunakan dalam penelitian ini mencakup data hasil tangkapan ikan lemuru (Sardinella longiceps) dan jumlah trip armada purse seine dalam periode 1989 - 1997, harga rata-rata tahunan ikan lemuru (Sardinella longiceps) dan biaya prlangkapan per trip upaya dalam periode 1995 - 1999.

Judul: Sustainability evaluation and the benefit optimization of lemuru (Sardinella Lemuru Bleeker 1853) fish resources at Bali Strait Waters
Abstrak: Ikan lemuru (Sardinella lemuru Bleeker 1853) merupakan sumberdaya perikanan yang sangat penting dan spesifik di perairan Selat Bali karena mempunyai peran strategis. Beberapa peneliti berpendapat bahwa ada kecenderungan penurunan produksi ikan lemuru yang diakibatkan oleh penangkapan berlebih (overfishing). Tujuan penelitian yakni: (a) mengevaluasi keberlanjutan pembangunan perikanan dengan pendekatan top down dan bottom up, (b) mengkaji optimalisasi pemanfaatan sumberdaya ikan lemuru, dan (c) mendesain strategi pembangunan perikanan yang berkelanjutan. Metodologi yang digunakan yakni survei dengan pendekatan expert system. Teknik analisis yang diterapkan yakni: (a) rapid appraisal fisheries (RAPFISH), multi criteria analysis (MCA), analysis of indicator linkages yang terdiri dari cognitive mapping dan centrality indicator, (b) analisis bioekonomi Gompertz, (c) Analytical Hierarchy Process.

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.
