Judul: Faktor-faktor yang Berkaitan dengan Kompetensi dalam Mengikuti Program Kreativitas Mahasiswa (PKM) (Kasus: Mahasiswa/i Departemen Ilmu dan Teknologi pangan Tahun Masuk 2008, Fakultas Teknologi Pertanian, Institut Pertanian Bogor)
Abstrak: The purpose of this study are to analyze the relationship of individual characteristics with the creativity of students, analyze the social influence of peer relationships with the creativity of students and analyze the relationship between student creativity with competence to participate in Student Creativity Program (SCP). This research was conducted at the Bogor Agricultural University, Department of Food Science and Technology, Faculty of Agricultural Technology. Data used in this study are primary and secondary data. The primary data obtained through interviews using questionnaire which is distributed and completed by the respondent In this study, the result of the individual characteristics consist of gender, academic achievement, organizational experience and achievement motivation is not all of them correlated with creativity. Only variable of organizational experience and achievement motivation are significantly associated with the creativity. In the social environment of peer group, the intensity of interaction is not correlated with the creativity. But only the support in peer group has correlated significantly with the creativity. Besides that creativity significantly correlated with competence in the student creativity program through the attitudes and skills variable. Creativity has no linkage with variable of knowledge in competence to participating in the Student Creativity Program.

Judul: Aktivitas Harian dan Prestasi Mahasiswa di Institut Pertanian Bogor.
Abstrak: Kegiatan sehari-hari dapat memberikan kesempatan bagi mahasiswa perguruan tinggi untuk mendapatkan prestasi akademik yang baik. Prestasi di perguruan tinggi dari kelompok besar mahasiswa yang memiliki bakat yang tinggi diperkirakan dari ketertarikan mereka, tujuan, kegiatan, konsep diri sendiri. Hal ini jelas bahwa kreativitas, dalam berbagai bentuk, adalah penting dalam kampus dan masyarakat. Tujuan dari penelitian ini adalah untuk mengetahui aktivitas dan prestasi belajar sehari-hari mahasiswa Institut Pertanian Bogor. Dalam menentukan kreativitas, subyek diukur dengan Adjective Check List. Hasil ini menunjukkan bahwa mahasiswa yang memiliki aktivitas ekstrakurikuler menunjukkan kinerja yang lebih baik untuk prestasi akademik yang baik. Analisis statistik menunjukkan bahwa ada hubungan positif yang signifikan antara IPK dan ekstrakurikuler (p=0.0265). Mahasiswa yang memiliki waktu makan yang lebih banyak memiliki IPK yang lebih baik dibandingkan yang tidak memiliki waktu makan yang banyak. Analisis statistik menunjukkan bahwa ada hubungan positif yang signifikan antara IPK dan makan (p=0.0305). Kreativitas tidak secara signifikan mempengaruhi kinerja akademik. Hubungan analisis statistik antara IPK dan kreativitas menunjukkan korelasi yang tidak signifikan (p=0.057). Kreativitas tidak dipengaruhi oleh kecerdasan.

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.
