Judul: Analisis Faktor-Faktor yang Mempengaruhi Perilaku Konsumen dalamKeputusan Pembelian Susu Cair Ultra Milk (Studi Kasus Mahasiswa S1 Institut Pertanian Bogor)
Abstrak: Indonesian people’s growing awareness of the impotance of liquid milk as a product for maintaining health, brings about an opportunity of marketing a product of liquid milk. A liquid milk industry is in fact dominated by popular players, among other things, Ultra Milk. Therefore, to maintain its market, Ultra Milk is supposed to know the factors influencing the making of the desicion of buying liquid milk. The consumers who have become a research target is a student of bachelor degree of Bogor Institute of Agriculture who has bought some liquid milk of Ultra Milk. This research is intended to as follows : (1) to identify the characteristic of the costumers of Ultra Milk, (2) to identify a process of deciding to buy Ultra Milk, (3) to analyze the factors influencing the customers’ decision to buy Ultra Milk, (4) to analyze customers attitude towards the attributes owned by Ultra Milk. The data used in this research are primary and secondary. The primary data are taken from the spreading of questionaires and the secondary data are taken from a library study, information on the internet, and a study of references. Secondary data are taken frombook’s study, internet and literature’s study.The technique to take samples used in this research is a quota sampling. The means of analyzing are the descriptive analysis, the factor analysis and a model of MultiattributeFishbein analysis with the help of SPSS software version 17 and Microsoft Excel. The results of the research show that the majority of the customers of Ultra Milk’s liquid milk are the female university students (62%), aged 21 years old (46%), their origins of Jakarta, Bogor, Tangerang and Bekasi (41%). Their average monthly expenses are from 500,001 rupiahs to 1,000,000 rupiahs ( 67%). The process to decide on buying the customers of Ultra Milk’s liquid milk goes through 5 phases namely, recognizing the need, searching for the information, evaluating the alternatives, buying and evaluating the. Referring to the factor analysis, there are 3 factors which are seen, among other things, the factors of individual characteristic, the knowledge of a product and a personality, and the source of information. Referring to the analysis of multiattributeFishbein, the customers put emphasis on the halal of a product, the quality of product and the security of a consuming process while buying liquid milk. The customers see Ultra Milk’s liquid milk from the quality of a product, the halal of a product and the security of a consuming process. Referring to the Fishbein score of 258.68, it is concluded that the product of Ultra Milk’s liquid milk is considered as a good category.

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.
