Judul: Analisis pengaruh kualitas layanan terhadap kepuasan nasabah (Studi kasus pada nasabah PT. Bank International Indonesia, Tbk Cabang Suryakencana Bogor
Abstrak: This economic growth also indirectly leads to an increase in the level of competition in banking industry. Thus, customer satisfaction becomes the key point to increase product sales in an effort to become a leader in the competition. The more a bank can guarantee customer satisfaction, the more sympathy and trust the bank gets from the customer. The way to serve the customers will greatly affect the number of customers and volume of customer purchases. Reliable product with great promotions will not produce maximum results without excellent customer service. As one of the leading private bank in Indonesia, BII has standard operating procedure that focuses on customer satisfaction. This makes BII always get a good appreciation of its customers ever since. The objectives of this research are (1) to analyze the effect of physical (Tangible) variable against customer satisfaction, (2) to analyze the effect of Reliability against customer satisfaction, (3) to analyze Responsiveness against customer satisfaction, (4) to analyze the effect of Assurance against customer satisfaction, and (5) to analyze the effect of Empathy against customer satisfaction. The research was conducted on customers of PT Bank International Indonesia, Tbk. The number of samples used in this study is a minimum of 125 respondents. Data analysis methods used are validity and reliability test questionnaire. The analysis tools are SEM or Stuctural Equation Model with the help of software SmartPLS. Based on these results it can be seen that the dimensions of service quality, namely tangible, responsiveness, and emphaty has significant positive effect to customers satisfaction of PT. Bank Internasional Indonesia, Tbk. However, reliability and assurance variable has no real effect to customer satisfaction. Variables of service quality dimension which have the most influence on customer satisfaction, which in this research has R-Square value of 0.640, are Tangible Variable (X1), followed by Responsiveness Variable (X3), and Emphaty Variable (X5). This result can be interpreted that customer satisfaction is influenced 64% by variable of service quality analized in this research and 36% by other variable uncovered by this research.

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.
