Judul: Analisa Variasi Karakter Morfometrik dan Meristik Kepiting Bakau (Scylla spp.) di Perairan Indonesia.
Abstrak: Indonesia memiliki sebuah garis hipotesis yang memisahkan wilayah geografi hewan Asia dan Australasia yang ditemukan oleh Alfred Russel Wallace yang bernama garis Wallace. Garis Wallace ditarik melalui kepulauan Melayu (di antara Kalimantan dan Sulawesi) serta di antara Bali dan Lombok. Keanekaragaman jenis hewan di bagian barat dari garis Wallace berhubungan dengan spesies Asia sedangkan di bagian timur berhubungan dengan spesies Australia. Oleh karena itu terdapat perbedaan karakteristik jenis hewan yang berada di wilayah barat dan timur Indonesia. Perbedaan karakteristik tersebut lebih terfokus pada fauna terestrial sedangkan perbedaan karakteristik pada fauna air belum banyak diketahui, salah satunya adalah kepiting bakau.

Judul: Sebaran dan Karakter Morfometrik Kepiting Bakau (Scylla serrata, Scylla olivacea) pada Ekosistem Mangrove di Kawasan Pesisir Pangandaran, Jawa Barat
Abstrak: Kabupaten Pangandaran memiliki potensi mangrove yang dijadikan sebagai habitat kepiting bakau. Penelitian ini bertujuan mengetahui sebaran dan karakter morfometrik kepiting bakau di kawasan Pesisir Pangandaran, Jawa Barat. Pengambilan data mangrove dan kepiting bakau dilakukan pada tiga stasiun. Data mangrove diambil dengan metode transek garis, dan data kepiting bakau diambil dengan menggunakan bubu. Setiap stasiun juga diambil data karakteristik lingkungan perairan. Terdapat tujuh jenis mangrove dan dua jenis kepiting bakau yang ditemukan di stasiun pengamatan, dimana kepiting bakau jantan Scylla serrata dan Scylla olivacea lebih banyak ditemukan. S. serrata dan S. olivacea memiliki korelasi yang erat antara lebar karapas dan bobot tubuh, dimana keduanya memiliki pertumbuhan allometrik negatif. Pada Stasiun pengamatan, 57% kerapatan mangrove Sonneratia alba paling berkontribusi terhadap kepadatan kepiting bakau S. serrata dan S. olivacea yang ada di kawasan Pesisir Pangandaran, Jawa Barat

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.
