Judul: Analisis Perilaku Pembelian dan Konsumsi Produk Suplemen Makanan
Abstrak: The objective of this research was to identify the consumption behavior of food supplement and to analyze the factors associated with buying and consumption behavior. This research was conducted at Tegal Gundil and Bantarjati villages (Northern Bogor Subdistrict) involving 100 purposively selected respondents. The respondents were at age of 20-65 year old and have consumed food supplement at least one product in the last month. Data collection was carried out through interviews using questionnaire. The research concluded that most of respondents consume tablet multivitamin of food supplement. It was about 83 brands of multivitamin mentioned by consumers. Which the Enervon-C was the most popular brand consumed. The greatest proportion of consumers consume at least a suggested portion in any relevant forms of food supplement a day (≥30 times/month). The results shows that the variables fo education and income have a negative significant relationship with the frequency of food supplement. Furthermore the variabel of income have a positive and significant relationship with the frequency of food supplement consumption.

Abstrak: Penelitian ini dilakukan dengan tujuan umum untuk mengetahui perilaku konsumsi makanan supiemen pada wanita dewasa di Kota Bogor. Seeara khusus tujuannya adalah mengetahui karakteristik contoh (usia, tingkat pendidikan, jenis pekerjaan, tingkat pendapatan, keadaan kesehatan, dan kondisi fisiologis), mengetahui jenis, merek dan bentuk (tablet, cair/sirup, serbuk dan kapsul) makanan suplemen yang dikonsumsi oleh wanita dewasa, mengetahui pola konsumsi (frekuensi dan jumlah konsumsi, alasan konsumsi dan manfaat konsumsi) makanan suplemen pada wanita dewasa, mengetahui persepsi contoh terhadap manfaat suplemen yang dikoosumsi, mengetahui sumber infonnasi dan tempat pembelian suplemen, dan mengetahui hubungan karakteristik (usia, tingkat pendidikan, jenis pekerjaan dan tingkat pendapatan, keadaan kesehatan dan kondisi fisiologis) contoh dengan pola konsumsi (frekuensi dan jumlah konsumsi) makanan suplcmen. Desain yang digunakan dalam penelitian ini adalah desain cross sectional study. yang dilakukan di Kota Bogar pada Januari 2002 - Februari 2003. Contoh dalam penelitian ini adalah wanita dewasa (20--60 tabun), yang memiliki telepon, tinggal di kompleks perumahan, bersedia diteLepon dan mengkonsumsi suplemen minimal satu kali dalarn satu bulan terakhir. Kerangka contoh diperoleh dari buku petunjuk telepon Bogor yang diterbitkan oleh PT Telkom periode waktu 1999 - 2000 yang tinggal di kompeks perumahan (Vila Duta, Bantar Jati, Bogor Bam, Taman Cimanggu. Indraprasta, Bumi Menteng Asri,' Cilendek Jndah, Cimanggu Permai, Good Year dan Telaga Kahuripan).

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.
