Judul: Analisis Proses Pengambilan Keputusan Pembelian dan Kepuasan Konsumen RM. Sop Ayam Pak Min Klaten Cabang Bogor
Abstrak: RM. Sop Ayam Pak Min Klaten Cabang Bogor is one of restaurant which offers traditional Javanese cuisine, especially chicken soup. The objectives of this study are to identify the characteristics of consumer, to analyze the decision buying process, to analyze the customer satisfaction level based on performance attributes of the restaurant, and to formulate alternatives marketing strategy. Data were collected by questionnaire survey to 100 respondents who were selected by convenience sampling. Descriptive analysis, Importance Performance Analysis (IPA), Customer Satisfaction Index (CSI), and gap analysis were employed in this research. The result of IPA showed some attributes to be improved, i.e. cleanness of the food and food equipment, cleanness of the restaurant, availability and cleanness of toilet and sink, availability of parking lot, and the comfort of restaurant. The result of CSI analysis showed that the level of consumer satisfaction was 75.27 percent, meaning that the consumers of RM. Sop Ayam Pak Min Klaten Cabang Bogor were satisfied.

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.
