Judul: Public Perception toward the Status Change from a Natural Reserve Area to Grand Forest Park of Pancoran Mas in Depok
Abstrak: Taman Hutan Raya adalah kawasan pelestarian alam untuk tujuan koleksi tumbuhan dan atau satwa yang alami atau buatan, jenis asli dan atau bukan asli, yang dimanfaatkan bagi kepentingan penelitian, ilmu pengetahuan, pendidikan, menunjang budidaya, budaya, pariwisata dan rekreasi. Cagar Alam yang merupakan status awal kawasan membuat fungsi kawasan ini seolah-olah tidak terkelola. Padahal saat ini fungsinya telah diubah menjadi Taman Hutan Raya, dimana kawasan ini bisa digunakan untuk kepentingan wisata sesuai pembagian blok pengelolaannya. Penelitian ini bertujuan untuk memahami persepsi masyarakat terhadap perubahan status kawasan Cagar Alam menjadi kawasan Taman Hutan Raya Pancoran Mas Depok dan mengidentifikasi faktor-faktor yang mempengaruhi persepsi masyarakat tersebut. Penelitian ini dilaksanakan pada bulan April sampai Mei 2012 dengan pemilihan responden menggunakan metode purposive sampling. Responden yang diambil, yaitu: laki-laki 26 responden dan perempuan 26 responden di Kelurahan Pancoran Mas, Depok. Faktor-faktor yang mempengaruhi persepsi dianalisis dengan menggunakan korelasi Rank Spearman dengan SPSS 16.0.

Judul: Sikap Masyarakat Kelurahan Pancoran Mas Terhadap Taman Hutan Raya Pancoran Mas, Depok.
Abstrak: Pancoran Mas Grand Forest Park is Located among residences, resulting interaction between grand forest park and the community. Today, only with a very bad repair iron fence that surrounding the park. This site had been neglected for several yaers. The main problem now is the management of this site. The effectivenes of grand foret park management depend on the recognition and support of the community living around the park. Knoweledge, attitudes and behaviour of the people will affect the grand forest park existence and conditions. Attitudes is a component that forms behaviour. This research is intended to measure the attitude of the people towards Pancoran Mas Grand Forest Park

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.
