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: Sekumpulan hak Masyarakat Adat Baduy atas sumber daya hutan^bKasus Desa Kanekes, Kecamatan Leuwidamar, Kabupaten Lebak Provinsi Banten
Abstrak: Hutan adat merupakan salah satu kawasan hutan masyarakat hukum adat yang diakui keberadaannya oleh negara. Masyarakat hukum adat merupakan masyarakat yang tinggal di dalam suatu kawasan dan memiliki seperangkat aturan dalam mengatur sistem kehidupannya. Setiap masyarakat hukum adat memiliki karakteristik yang unik. Masyarakat Suku Baduy misalnya, memiliki ciri khas yang unik dan berbeda dari masyarakat pedesaan dan perkotaan. Salah satu keunikan tersebut dapat dilihat dalam bentuk pengelolaan sumber daya hutan yang menjadi sumber daya milik bersama untuk pemenuhan kebutuhan sehari-hari. Terdapat sekumpulan hak dalam pemanfaatan sumber daya hutan. Penelitian ini bertujuan untuk menganalisis sejauh mana keterkaitan karakteristik masyarakat adat Baduy dengan sekumpulan hak atas sumber daya hutan. Metode penelitian yang digunakan adalah penelitian survei dengan menggunakan instrumen kuesioner dan didukung oleh data kualitatif melalui wawancara mendalam. Hasil penelitian menunjukkan bahwa tidak terdapat keterkaitan antara karakteristik umur, status perkawinan dan pendapatan dengan sekumpulan hak atas sumber daya hutan. Namun hasil penelitian ini juga menunjukkan bahwa terdapat keterkaitan antara karakteristik jenis kelamin dan status sosial masyarakat adat dengan sekumpulan hak atas sumber daya hutan.

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.
