Judul: Analisis Kepuasan dan Loyalitas Konsumen Jigoku Ramen, Bandung, Jawa Barat
Abstrak: This study aims (1) to analyze the characteristics of consumers in Jigoku Ramen, (2) to analyze the buying decision process, (3) to analyze the level of consumer satisfaction, and (4) to analyze the level of consumer loyalty. The sampling method used was convenience sampling. Descriptive analysis, Importance Performance Analysis (IPA), Customer Satisfaction Index (CSI), and loyalty pyramid were employed in this study. There were 100 respondents participated on this research. The major respondents were female customers of 19-24 years old who live in Bandung, mostly students, single marital status, and high school graduates. Their average income per month was IDR500 000–IDR1 500 000, and their average spending in Jigoku Ramen was IDR50 000–IDR100 000. The descriptive analysis described the level of needs, the source of information about the restaurant, the evaluation of alternative options, the consuming process, and after-consuming process. The analysis of Customer Satisfaction Index (CSI) showed that this restaurant was rated by 72.48 percent. It means that the most costumers were satisfied by Jigoku Ramen’s performance. The consumer loyalty was rated by 91 percent, meaning that consumers were mostly loyal buyer.

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.
