Judul: Analisis perilaku konsumen dalam keputusan pembelian laptop merek Asus (Studi kasus mahasiswa S1 Institut Pertanian Bogor)
Abstrak: Business competition among manufacturers of laptop industry are very high to make Asus as a manufacturer and marketer of a fairly large laptop in Indonesia tried to maintain its market share, Asus should know in detail the behavior of consumers which will be the targeting of their products. Data processing is done by descriptive analysis, factor analysis, and analysis of Fishbein multiatribute. Based on the results of the study showed that the majority of respondents' characteristics-sex male, aged 21 years, and is undergoing classes in semester 7. The majority of respondents came from West Java, financial resources come from parents with average income of Rp. 500,001.00 - Rp. 1,000,000.00. Based on factor analysis, showed that the purchase of a laptop Asus affected by five major factors, there are seller influence factor , the factor of experience using different brands of laptops, feature factor, factor of status as a student, and a friend of factors influence. In the analysis of consumer attitudes, attributes are a major consideration in their buying decision is product quality, product benefits and features of products. Attributes which not considered to be most important is the color of the product. Consumer attitudes toward the attributes possessed Asus laptop can be good.

Judul: Analisis Brand Equity Laptop pada Mahasiswa S1 IPB
Abstrak: Pertumbuhan industri laptop di Indonesia semakin meningkat menyebabkan daya saing antar vendor semakin ketat sehingga produsen laptop berlomba-lomba menampilkan keunggulan masing-masing merek, di mana salah satunya laptop merek Asus yang merupakan vendor laptop terbesar kedua di Indonesia. Kekayaan merek akan mempengaruhi konsumen dalam kesadaran merek, pencitraan merek, persepsi kualitas hingga kesetiaan pada merek. Tujuan penelitian ini adalah menganalisis ekuitas merek dengan melihat lebih terperinci pada brand awareness, brand association, perceived quality, dan brand loyalty pada laptop Asus. Data bersumber dari data primer dan sekunder. Data primer berupa hasil wawancara dengan menggunakan instrumen kuisioner, sedangkan data sekunder diperoleh melalui studi literatur, majalah, internet, dan artikel terkait penelitian. Penarikan sampel menggunakan teknik quota sampling. Uji reliabilitas data menggunakan metode product moment dengan tingkat signifikansi sebesar 5 persen, sedangkan uji validitas menggunakan teknik K-R 20 untuk asosiasi merek dan teknik cronbach untuk perceived quality. Hasil penelitian menyatakan laptop merek Asus menjadi top of mind, asosiasi pembentuk brand image laptop Asus adalah produk berkualitas, produk inovatif, teknologi canggih, merek terkenal dan harga kompetitif. Pada perceived quality, atribut tersebar pada kutub positif dengan rentang skala cukup, baik dan sangat baik. Atribut laptop Asus yang termasuk skala sangat baik adalah produk mudah ditemui di pasaran. Analisis brand loyalty menyatakan piramida yang terbentuk dari laptop Asus belum ideal karena semakin ke atas luas wilayah tingkatan brand loyalty, maka semakin mengecil.

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.
