Abstrak: The aims of this research were (1) to know the development of "Kaki Lima" fried chicken bussiness, (2) to know income rate from "Kaki Lima" fried chicken bussiness, (3) to know the supporting and constraint factors in development the bussiness, (4) to know labour's absorption by "Kaki Lima” fried chicken bussines . This research was held on April until June 2007 at several sub districts in Bogor City. The data were analyzed by descriptive analysis, including income, R/C Ratio, labour absorption, and Rank"s Spearman (Rs) correlation. The result of this research were: 1) Business development of "Kaki Lima"fried chicken have a good prospect that shown by large empolyed and income. Rank's Spearman coefficient showed that unit periode on "Kaki Lima” fried chicken business had significant correlation to income rate and bussines scale, 2) Average Income of "Kaki Lima" fried chicken bussiness was Rp 2.931.108,65 per month and R/C ratio was 1,27. It means that "Kaki Lima" fried chicken bussiness was profitable. Rank"s Spearman coefficient showed that bussiness scale on "Kaki Lima" fried chicken had significant correlation with income rate, 3) Supporting factors of bussiness "Kaki Lima" fried chicken in Bogor City are financial aspect, material supplier, marketing, and technology. The constraint factor of bussiness "Kaki Lima" fried chicken are raw material price, capital and goverment factor, 4) Labour absorptions in "Kaki Lima” fried chicken bussiness are 65 labour. Rank's Spearman coefficient showed that the scale of "Kaki Lima" fried chicken had no correlation with labour absorption.

Judul: Analisis Kelayakan Pengembangan Cabang Baru Usaha Restoran Fried Chicken (Studi Kasus: Azyro Fried Chicken)
Abstrak: UMKM merupakan salah satu penggerak perekonomian nasional yang terbukti dapat bertahan terhadap krisis ekonomi. Salah satu UMKM yang bergerak pada sektor restoran adalah restoran Fried chicken. Restoran Azyro Fried chicken merupakan usaha restoran yang berada di jalan Bogor Sukabumi, Kecamatan Caringin, Kabupaten Bogor. Usaha Restoran ini sudah 3 tahun berdiri dan akan mengembangkan usahanya dengan menambah cabang baru yang berada di Parung Kuda. Penelitian ini bertujuan untuk (1) Menganalisis kelayakan pengembangan usaha restoran berdasarkan aspek non-financial,(2) Menganalisis kelayakan usaha berdasarkan aspek financial dan (3) Menganalisis sensitivitas dengan menggunakan switchingvalue terhadap kelayakan pengembangan usaha. Penelitian menggunakan analisis aspek nonfinancial yaitu aspek pasar, aspek teknik, manajemen, aspek hukum dan aspek sosial. Aspek financial meliputiNPV (Net present value), IRR (Internal rate of return),Net B/C, PP (Payback periode).Analisis finansial yang dilakukan menghasilkan nilai NPV positif sebesar Rp 188 330 833, IRR sebesar34,07% lebih besar dari nilai suku bunga. Nilai net B/C diperoleh nilai 1.56 dan PBP mengasilkan 2.92 tahun, menunjukan bahwa usaha ini layak dan dapat untuk mengembangkan cabang baru.

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.
