Judul: Faktor-faktor yang Mempengaruhi Keputusan Pembelian di Restoran Waroeng Taman Kota Bogor
Abstrak: The restaurant industry is highly competitive with respect to price, value and promotions, service, location, and food quality. Waroeng Taman restaurant has a natural concept that offers the food with Indonesian taste. The objectives are to identify the characteristics of consumer, analyze the process of purchasing decision, and analyze the influence factors of consumers purchasing decision at Waroeng Taman. The methods are using descriptive analysis and factor analysis. Descriptive analysis was used to describe the characteristics of consumer and the process of purchasing decision. Factor analysis was used to analyze the influence factors of consumers purchasing decision. There were six major influence factors of the consumers purchasing decision at Waroeng Taman, they were the service factor, the psychological process factor, the influence of environment factor, the product factor, the individual differences factor, and the external factor. Service factor was the main factor influencing the purchasing decision.

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.
