Judul: Analisis Keputusan Konsumen serta Implikasi terhadap Bauran Pemasaran Restoran DBC & Spageti, Kota Bogor
Abstrak: DBC & Spageti restaurant is a restaurant that serves a variety of menubased chocolate and spaghetti. The purpose of this research is to analyze the purchase decision prosess of consumers, the factors which can influence consumer purchasing decisions, the importance satisfaction level for performance attributes that will provide an alternative strategy attributes repairment in DBC & Spageti restaurant. The method of research is a descriptive analysis method, Customer Satisfaction Index (CSI), and Importance Performance Analysis (IPA).In the purchasing decision (nature of the visit depends on the situation, frequency of purchase only once a month, the visit does not necessarily, time to visit at afternoon, and the costs which is spend for eating from 50 000 until 100 000), and post-purchase decision are consumers satisfied and consumers have an interest to come back again. The results are the consumer satisfaction rate at DBC & Spageti restaurant is satisfied and can be seen from Costumer Satisfaction Index which is at 77.07 percent that will mean the consumers are satisfied.

Judul: Analisis keputusan pembelian konsumen di RM. Bumi Aki Kota Bogor
Abstrak: Bogor is a well known city for culinary recreation in JABODETABEK. The emerging of Bumi Aki restaurant in Bogor has made the competition in culinary sector more competitive. The purpose of this research was to analyze the process of purchasing decision and consumer satisfaction of Bumi Aki restaurant. The purchasing decision process was analyzed in a descriptive way, and the consumer satisfaction level was analyzed using Importance Performance Analysis (IPA) and Customer Satisfaction Index (CSI). Based on IPA, there were three attributes located in quadrant I wich they performance were the main priority to be fixed, they were foods and beverages prices, order service speed, and responsiveness of complain handling. Attributes that located in quadrant II, wich they performance were need to be maintained, were foods and beverages taste, restaurant location, restaurant cleanliness, parking lot capacity, restaurant comfortness, and waitress hospitality and politeness. The result of CSI showed that consumers of Bumi Aki restaurant 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.
