Judul: Perencanaan interpretasi di suaka margasatwa Pulau Rambut, Kepulauan Seribu DKI Jakarta
Abstrak: Pulau Rambut pertama kali ditetapkan sebagai Cagar Alam pada tahun 1939 melalui Keputusan Gubernur Jenderal Hindia Belanda No.7/1939. Selanjutnya, pada tahun 1970 pemerintah Indonesia memperkuat status kawasan ini sebagai Cagar Alam melalui Keputusan Pemerintah No.11/I/20 tertanggal 28 Mei 1970. Kemudian melalui Keputusan Menteri Kehutanan dan Perkebunan Indonesia No. 275/Kpts-II/1999, ditetapkan menjadi Suaka Margasatwa. Perubahan status kawasan ini disebabkan oleh terjadinya perubahan kondisi alami di Pulau Rambut, sehingga perlu adanya upaya pengelolaan habitat di Pulau Rambut.

Judul: Analisis kebijakan perubahan fungsi cagar alam pulau rambut menjadi suaka margasatwa
Abstrak: Pulau Rambut saat ini mengalami berbagai tekanan yang dapat mengancam kelestarian ekosistem dan keanekaragarnannya. Mengingat pentingnya Pulau Rambut dan krisisnya kondisi kawasan tersebut, maka Menteri Kehutanan dan Perkebunan mengeluarkan Surat Keputusan Perubahan Fungsi Cagar Alam Pulau Rambut menjadi Suaka Margasatwa pada tahun 1999. Penelitian ini bertujuan untuk mengetahui dan menggali potensi Pulau Rambut. serta persepsi stakeholders/key persons mengenai Pulau Rambut. Selain itu. penelitian ini menganalisis alternatif pengelolaan yang optimal dalam pemanfaatan Pulau Rambut, sebagai wujud analisis kebijakan perubahan fungsi cagar alam Pulau Rambut men. adi suaka margasatwa.

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.
