Judul: Partisipasi masyarakat adat dalam pelestarian hutan : studi kasus masyarakat kampung Cibeo (Baduy dalam), Desa Kanekes, kecamatan Leuwidamar, kabupaten Lebak, Propinsi Banten
Abstrak: Penelitian dilakukan di kampung Cibeo (Baduy Dalam), Desa Kanekes, Kecamatan Leuwidamar, Kabupaten Lebak, Propinsi Banten. Pemilihan lokasi dilakukan dengan cara sengaja (purposive) dengan pertimbangan bahwa masyarakat Baduy merupakan masyarakat adat yang memiliki ciri khas tersendiri dalam pelestarian hutan. Dipilihnya masyarakat Baduy Dalam karena mereka hanya memanfaatkan hutan yang ada diwilayahnya dan mereka lebih kuat memegang aturan adat dari pada Baduy Luar. Serta banyak larangan yang muncul dari tempat tersebut. Masyarakat Cibeo lebih mudah bergaul dengan "orang luar" dibanding dengan kampung lainnya. Penelitian ini dilakukan selama dua bulan, yaitu bulan Oktober sampai November 2003. Hasil penelitian menunjukkan bahwa partisipasi masyarakat diwujudkan dalam bentuk perilaku mereka dalam pemanfaatan hutan, pengelolaan hutan dan perlindungan hutan. Perilaku tersebut dilakukan secara sukarela dan didasarkan pada agama Sunda Wiwitan, yang mengharuskan masyarakat untuk tetap melestarikan alam semesta yang dititipkan oleh Tuhan. Dengan demikian dapat dikatakan masyarakat Baduy berpartisipasi tinggi dalam pelestarian hutan.

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: 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.
