Judul: Pengaruh Manajemen Kerelasian Pelanggan terhadap Loyalitas Nasabah PT Bank Muamalat Indonesia,Tbk Cabang Bogor
Abstrak: Loyalty is a customer commitment to constantly resubscribe and repurchase a product or service in the future. Every company wants the customer to have high loyalty toward their products, so does PT Bank Muamalat Indonesia (BMI), Tbk Branch Bogor. Loyalty appears because of customer satisfaction and good relationship between the customer and the company. Customer relationship management is needed to mantin a good relationship between the customer and the company. Customer relationship management in BMI is a company approaching to (1) customer identification (IDENT), (2) customer differentiation (DIFFER), (3) interaction to retain (INTER) and (4) technology development (TEKNO). The fourth independent variables, satisfaction (PUAS) and loyalty (LOYAL) as the dependent variables are variables that can not be measured 6 directly, so they are needed to take a few indicators as a measurement. Structural equation modeling is an approach that can be used to solve the problem. The structural equation modeling analysis is needed to see how customer relationship management and customer satisfaction influence customer loyalty. The result shows that the development of technology (TEKNO) is the factor that influences satisfaction (PUAS) and it is effected to customer loyalty (LOYAL).

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.
