Judul: Analisis Dampak Ekonomi Kegiatan Wisata Alam (Studi Kasus: Floating Market Lembang, Bandung)
Abstrak: The tourism industry is one sector that can improve the economic progress of society. Lembang Floating Market is one area that has great potential and has appeal as a tourist area. The specific objective of this research is to identify the characteristics of the visitors, business units, and manpower around the Lembang Floating Market, identify factors that affect tourism demand, estimating the economic impact of tourism activities of Lembang Floating Market. The results of this research show that the average age of visitors Lembang Floating Market is 17-25 years old with an average visitor job is as private employees and earn between Rp 500,000 to Rp 2,000,000, most visitors come from Bandung. Factors that influence (at 5% significance level) is the level of income, travel expenses, mileage, and the number of families. Value of economic impact is estimated using a multiplier effect approach includes direct economic impact can be felt by the owner of a business unit of Rp 1,109,671,742 , indirect economic impacts in the form of spending a business unit within the tourist area of Rp 1,120,265,853 , while the advanced economic impact in the form of expenditure manpower in the tourist area of Rp 90,784,891. Value of Keynesian income multiplier is 1.3, the ratio of income multiplier type I is 2.0, ratio income multiplier type II is 2.1.

Judul: Analisis dampak ekonomi kegiatan wisata alam (Studi kasus : Taman wisata Tirta Sanita, Kabupaten Bogor)
Abstrak: Sektor pariwisata erat hubungannya dengan wisatawan. Tingkat permintaan atau kunjungan wisata akan berdampak secara langsung maupun tidak langsung terhadap pemerintah dan masyarakat lokal, seperti peningkatan pendapatan, menciptakan lapangan pekerjaan dan dapat menunjang pengembangan wilayah tersebut. Pengeluaran wisatawan selama melakukan perjalanan wisata akan mendorong terciptanya transaksi ekonomi. Adanya transaksi tersebut menimbulkan dampak ekonomi bagi masyarakat sekitar lokasi wisata. Berdasarkan latar belakang tersebut maka dilakukanlah penelitian ini. Adapun permasalahan yang akan dijawab dalam penelitian ini adalah 1) Bagaimana karakteristik masyarakat sekitar, unit usaha, tenaga kerja dan pengunjung Taman Wisata Tirta Sanita? 2) Faktor-faktor apakah yang mempengaruhi permintaan wisata di lokasi Taman Wisata Tirta Sanita? 3) Bagaimana dampak ekonomi yang ditimbulkan oleh kegiatan wisata alam berbasis masyarakat lokal di sekitar Taman Wisata Tirta Sanita?. Penelitian ini dilaksanakan di Taman Wisata Tirta Sanita yang terletak di Desa Bojong Indah, Kecamatan Parung, Kabupaten Bogor. Data yang digunakan terdiri dari data primer dan data sekunder. Data primer meliputi karakteristik pengunjung Taman Wisata Tirta Sanita, pendapatan dari unit usaha, pendapatan dan pengeluaran tenaga kerja lokal di lokasi wisata dan keterlibatan masyarakat lokal sekitar. Data sekunder meliputi keadaan umum lokasi wisata (sejarah, status, letak dan luas, keadaan fisik serta potensi wisata) dan jumlah kunjungan pengunjung yang diperoleh dari pengelola wisata dan studi literatur lainnya. Analisis menggunakan Metode Biaya Perjalanan dengan alat pengolah data Stata 9 dan Keynesian Income Multiplier untuk mengetahui dampak ekonomi yang diolah dengan Microsoft Excel 2007.

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.
