Judul: Valuasi ekonomi ekosistem terumbu karang di perairan pulau menjangan Provinsi Bali
Abstrak: Perairan Pulau Menjangan adalah salah satu wilayah terumbu karang di kawasan Taman Nasional Bali Barat. Fungsi ekologi terumbu karang hams menjadi bagian dari perhitungan untuk merencanaltan pengelolaan area terumbu karang yang lebih berkelaniutan. Untulc itu, diperlukan analisis nilai ekonomi terumbu karang, termasuk kilas fungsi ekologisnya.Hasil penelitian menunjukkan bahwa jenis manfaat langsung (Direct Use) yang dapat diidentifikasi dan kuantifikasi dari ekosistem terumbu karang di perairan Pulau Menjangan adalah pemanfaatan ikan hias yang bernilai Rp36.562.500 per tahun.

Judul: Pengembangan Wisata Bahari Berbasis Sumberdaya Terumbu Karang di Pulau Menjangan, Taman Nasional Bali Barat
Abstrak: Pulau Menjangan termasuk kedalam pulau yang dapat dimanfaatkan untuk kegiatan wisata selam. Memberikan gambaran mengenai potensi sumberdaya terumbu karang, menganalisis indeks kesesuaian wisata dan daya dukung kawasan serta merumuskan strategi pengelolaan dan pengembangan ekowisata selam. Identifikasi karang dikaji menggunakan metode transek garis sedangkan kelimpahan jenis ikan karang dikaji menggunakan metode fish visual cencus. Analisis data yang digunakan adalah analisis potensi terumbu karang, analisis kesesuaian lahan, analisis daya dukung dan analisis SWOT. Tutupan komunitas karang hidup berkisar antara 60,62%-78,64% dengan jumlah ikan karang berkisar antara 103-462. Indeks kesesuaian wisata (IKW) selam di Pulau Menjangan termasuk dalam kategori sesuai (S2) dan sangat sesuai (S1) dengan nilai daya dukung kawasan adalah 125 orang/hari. Strategi prioritas yang perlu dilakukan di kawasan Pulau Menjangan adalah strategi pengelolaan SO (Strength Opportunity).

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.
