Judul: Biologi Reproduksi Ikan Pepetek Leiognathus equulus (Forsskal 1775) di Perairan Selat Sunda.
Abstrak: Ikan pepetek (Leiognathus equulus) merupakan salah satu jenis ikan yang didaratkan di pelabuhan perikanan pantai (PPP) Labuan Banten. Penelitian ini bertujuan mengkaji aspek biologi reproduksi ikan pepetek (Leiognathus equulus) di perairan Selat Sunda. Penelitian ini dilaksanakan pada bulan April 2015 sampai bulan Agustus 2015 di PPP Labuan Banten. Ikan pepetek yang didapatkan selama penelitian berjumlah 945 ekor, terdiri dari 507 ekor ikan jantan dan 438 ekor ikan betina, dengan kisaran panjang total antara 78 ����� 260 mm, dan kisaran berat total 11 ����� 188 gram. Proporsi kelamin ikan jantan dan betina setiap bulan pengamatan berdasarkan uji Chi square adalah tidak seimbang. Ikan pepetek jantan dan betina memiliki pola pertumbuhan alometrik negatif. Ikan pepetek diperkirakan memijah setiap bulan dengan puncak pemijahan pada bulan Juni. Ikan jantan pertama kali matang gonad pada ukuran panjang 150 mm dan ikan betina pada ukuran panjang 146 mm. Berdasarkan tipe pemijahan, pola penyebaran diameter telur ikan pepetek adalah partial spawner yaitu kelompok ikan yang memijah dengan mengeluarkan telur secara bertahap.

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.
