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: 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: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
