Judul: Kelembagaan Pengelolaan Sumber Daya Hutan Masyarakat Adat Baduy Desa Kanekes, Kecamatan Leuwidamar, Kabupaten Lebak, Propinsi Banten
Abstrak: Baduy is a traditional society in Indonesia who still keep the custom and tradition of their anchestor. Baduy society have uniqueness of traditional knowledge in their forest resources management. Its related with their tradition and the effect of anchestors credentials. The Baduy society lifelihood cannot be released from pikukuh (a guide, tradition, life regulation and credentials) that they obedient, which used for control their life. Pikukuh is a hereditary legal heir from their anchestors and never changed. Yet, the outside cultures developed make pikukuh changed, especially in Baduy Luar. In some cases, the Baduy society starts to leave their obedient to pikukuh, include the way to make decision about conservation in their society. The research purpose are to analyze the traditional knowledge and the experience of Baduy society in managing their forest resources, involving the conservation decision making. This research is a quality qualitative research which use the participant observation method by associate with the society and observe their social life. Eventhough a lot of the introduce of culture come inside, Baduy society have a traditional knowledge for generation. Baduy experiences in manage the foest give an effect balances in ecology

Judul: Persepsi, Motivasi, Sikap Dan Perilaku Masyarakat Lokal Terhadap Keberadaan Hutan (Kasus Di Kecamatan Gn. Kencana, Kabupaten Lebak, Propinsi Banten)
Abstrak: A good forest management is an important part to get sustainable forest in Gn. Kencana where “Baduy Luar” and non Baduy in local community live. The aim of this research is to analyze perception, motivation, attitude and behavior from Baduy Luar and non Baduy community in Gn. Kencana about managing their forest in their area. This research use purposive sampling to get 30 respondent and 3 village sampling (Cimanyangray, Sukanegara and Keramatjaya) in Gn.Kencana . Perception for land use is for farming area. Perception for wood can get from quantity from that forest, closed standing stock, and diameter of trees. And then, for perception of water, it can get from periods water flow, and clear of water condition. The result, Baduy Luar communities have better perception than non Baduy about this forest. Local communities have motivation to subtantiate for life and to increase economic value from forest resources. Actually, both of them are agree to conserve the land forest, source of wood and water supply. We can look that action from a part of Baduy Luar community get source of wood from twig or natural died tree. Altough non Baduy community will cut the trees when they want. Local wisdom still be a part of Gn. Kencana community when they use natural resources (in this case is forest), especially for Baduy Luar. Keywords : Gn. Kencana, Perception, motivation, attitude and behavior

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.
