Judul: Studi tentang stok dan analisis pertumbuhan Ikan Swanggi (Priacanthus spp) di Perairan Selat Makasar, Kalimantan Timur
Abstrak: Survai trawl terhadap ikan-ikan demersal di Perairan Selat Makasar, Kalimantan Timur yang dilakukan pada 17 stasiun penangkapan menghasilkan dugaan besarnya potensi ikan swanggi yang dapat dimanfaatkan per tahun, berikut laju penangkapan, kepadatan stok, dan biomassanya. Selain itu juga dilakukan analisis terhadap hubungan antara panjang dan berat kedua jenis ikan swanggi guna melihat pola pertumbuhannya. Untuk melihat penyebaran ikan swanggi secara vertikal maka dilakukan pembagian stratifikasi kedalaman dalam analisis pendugaan parameter-parameter seperti yang telah disebutkan di atas. Ikan-ikan yang tertangkap terdiri atas 30 famili ikan demersal, 4 famili ikan pelagis, serta cumi-cumi dan sotong. Di antara ke-30 famili ikan demersal tersebut terdapat 9 famili yang memberikan hasil tangkapan yang melimpah dibandingkan dengan famili lainnya. Di antara ke- 9 famili ikan demersal tersebut adalah, famili ..dst

Judul: Kajian Stok Ikan Swanggi (Priacanthus Tayenus Richadson, 1846) Di Perairan Selat Sunda Yang Didaratkan Di Ppp Labuan, Banten
Abstrak: Ikan swanggi merupakan salah satu jenis ikan demersal di perairan Selat Sunda yang memiliki nilai ekonomis yang tinggi yang didaratkan di PPP Labuan. Tujuan penelitian ini ialah mengkaji status stok ikan swanggi. Parameter yang diamati antara lain panjang total, bobot, jenis kelamin, dan tingkat kematangan gonad. Total ikan swanggi yang diamati mencapai 537 ekor. Rasio kelamin ikan betina dengan jantan adalah 1.3:1. Pola pertumbuhan ikan swanggi di perairan Selat Sunda bersifat allometrik negatif. Nilai panjang asimtotik (L∞) ikan betina adalah 336.59 mm, sedangkan jantan sebesar 313.43 mm. Koefisien pertumbuhan (K) ikan jantan lebih besar (0.34) dibandingkan ikan betina (0.17). Laju eksploitasi ikan betina (0.74) dan jantan (0.80) melebihi 0.5, yang artinya ikan swanggi baik betina maupun jantan telah mengalami tangkap lebih.

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.
