Judul: Studi pemanfaatan sarang semut (Myrmecodia pendans Merr. & Perry) oleh masyarakat sekitar taman nasional Wasur
Abstrak: Wasur National Park O;VNP) is located in Merauke Regency, south of Papua Province. In the early of 2006, was introduced one of herbal &om Papua which has attrach of great attention of public which is sarang semut (Mynitecodia pendans). Sarang semut can be use to healing serious diseases and to making survival of live more longer, so that the price of Sarang Semut increase drasticly. The aims of this research were to dig the knowledge and cultural of community, Marind Sendawi Anim tribe, in using medical plants especially Sarang Semut (Myrt~tecodiap endans) in traditionally. The research was conducted Erom April to May 2008 in Wasur National Park, and interview method was used with respondents who considered knows about using plants medical (snowball method). Data which obtained can be tabulated systematically and analyzed descriptively. Results show that Sarang Semut was used by traditional people (Kanume tribe, Marori tribe, Men-Gei tribe, Yeinan tribe, and Marind tribe) for 3 things: poultry woof, medical plant and economy (sources of revenue). There are six beneficial's for traditional healing i.e. stiff of muscles, kidney disorder, dizzy, give birth to, stiff and waist. Tuber is the part of this plant that was used for medical. Its tuber was boiled either burned before used. Another using with trading, increase the welfare of people. Trading schema is Erom harvester to collector and then to consumer. There is variation in each step of trading schema. Prices in harvester level ranged from Rp. 5.0001sach - Rp. 20.000lsach, consumer 1 (grosser) ranged &om Rp. 25.000 - Rp. 60.0001 kg.

Judul: Potensi dan Karakteristik Bio-ekologis Tumbuhan Myrmecodia spp. di Taman Nasional Wasur Merauke Papua
Abstrak: Tumbuhan sarang semut termasuk salah satu spesies tumbuhan obat yang dapat menyembuhkan berbagai macam penyakit. Tumbuhan tersebut di Taman Nasional Wasur Merauke belum dilakukan upaya pembudidayaan dan pemanenannya masih dilakukan dari alam. Informasi tenang potensi dan karakteristik bio-ekologis belum tersedia dan teknik pengelolaannya bagi ketersediaan di alam dan budidayanya belum tersedia. Penelitian ini dilakukan dengan tujuan untuk: (1) mengidentifikasi bioekologis tumbuhan obat sarang semut, (2) menentukan potensi tumbuhan obat sarang semut berdasarkan tipe penutupan lahan di TN Wasur, (3) menentukan interaksi karakteristik bio-ekologis dengan kerapatan tumbuhan sarang semut di kawasan TN Wasur, dan (4) menentukan preference tumbuhan sarang semut terhadap jenis tumbuhan inang. Dalam penelitian ini peubah yang diamati dan diukur adalah diameter jenis vegetasi tingkat pohon tumbuhan inang, diameter jenis vegetasi tingkat pohon tumbuhan inang, diameter jenis vegetasi tingkat pohon tumbuhan inang, kerapatan tumbuhan habitus epifit, kerapatan tingkat pohon tumbuhan inang, kerapatan tingkat tiang tumbuhan inang, kerapatan tingkat pancang tumbuhan inang, jumlah spesies tumbuhan inang tingkat pohon, tiang dan pancang dan persentase keterbukaan tajuk.

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.
