Judul: Analisis ekonomi dan kebijakan pengelolaan wisata alam berbasis masyarakat lokal di Kabupaten Administrasi Kepulauan Seribu Provinsi DKI Jakarta
Abstrak: Pariwisata telah menjadi bagian dari komoditi yang banyak digunakan oleh suatu wilayah sebagai salah satu sumber pendanaan pembangunan. Data sektor pariwisata di Indonesia menunjukkan pertumbuhan yang signifikan. Saat ini pemerintah Indonesia tengah mengupayakan kegiatan wisata yang diantaranya berlokasi di kawasan pelestarian alam dengan harapan dapat memberikan dampak ekonomi yang signifikan sekaligus melaksanakan upaya konservasi. Indonesia memiliki banyak kawasan wisata bahari, salah satunya adalah kawasan Kepulauan Seribu. Wilayah ini terdiri dari  110 pulau-pulau kecil, dengan berbagai pemanfaatan. Salah satu pemanfaatan yang berdampak positif bagi kegiatan perekonomian masyarakat lokal adalah kegiatan wisata bahari. Tujuan utama penelitian ini adalah melakukan analisis dampak ekonomi wisata alam. Penelitian ini difokuskan pada perspektif ekonomi wisata alam di negara berkembang.

Judul: Penilaian Ekonomi dan Daya Dukung Wisata Bahari di Pulau Pari Kepulauan Seribu Provinsi DKI Jakarta
Abstrak: The economic assessment and carrying capacity of Pari island marine tourism in Thousand islands of DKI Jakarta province are intended to determine the land suitability of Pari island for the marine tourism, to estimate the physical carrying capacity of Pari island for the marine tourism, to estimate the economic values of Pari island for the marine tourism and the economic impacts for the local people. The analysis of tourism land suitability shows that the group of Pari island in accordance with the parameter of brightness and flow velocity is really appropriate with the parameter of the types of coral reefs and reef fish species, is appropriate with margin and is sufficiently appropriate with the live coral cover; and in accordance with the width parameter is of the potential for 361,5 ha diving and 939,55 ha snorkeling activities. The carrying capacity of the group of Pari island for diving tourism is 1.287 people/day, for snorkeling tourism is 2.787 people/day, for mangrove tourism is 504 people/day, and for beach tourim is 2.572 people/day. The results showed the total economic value of marine tourism in Pari island about 12.365.824.221,25 IDR or 192.314.529,10 IDR per hectare/year. Keynesian Local Income Multiplier value of cash flow marine tourism activities in Pari Island showed a value of 1,48, Income Multiplier Ratio Type I and Income Multiplier Ratio Type II with value of 1,09, and 1,14.The recommendations for the marine tourism development in Pari island are among other: the settlement of land ownership status; involvement, capacity development, and community empowerment; the opening of direct transport access toward Pari island; the improvement of infrastructures and tourism supporting facilities

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.
