Judul: Pengelolaan Resolusi Konflik Agraria Kawasan Taman Nasional Gunung Gede Pangrango: Strategi Kolaborasi dan Keberlanjutannya
Abstrak: Perubahan rezim kawasan hutan dari Perhutani ke Taman Nasional Gunung Gede Pangrango menyebabkan masyarakat di sekitar kawasan Taman Nasional tereksklusi dari kawasan hutan. Hal tersebut telah mendorong terjadinya konflik agraria. Konflik tersebut dapat diatasi dengan resolusi konflik. Resolusi konflik yang dilakukan berupa kolaborasi. Hal terakhir ini bertautan dengan mewujudnya keberlanjutan pada dimensi ekologi, sosial, dan ekonomi. Tujuan umum penelitian ini yaitu menganalisis pengelolaan resolusi konflik agraria kawasan Taman Nasional Gunung Gede Pangrango, strategi kolaborasi, dan keberlanjutannya. Penelitian ini dilakukan di Blok Sarongge, Desa Ciputri, Kecamatan Pacet, Kabupaten Cianjur dengan melibatkan 46 eks penggarap hutan. Penelitian ini menggunakan pendekatan kuantitatif dengan metode survei dan didukung oleh data kualitatif. Analisis data menggunakan uji korelasi Rank Spearman. Hasil penelitian menunjukkan, adanya hubungan yang cukup dan signifikan antara tipe pengelolaan kolaborasi consultative dengan tingkat keberlanjutan masyarakat dan lingkungannya.

Judul: Pengelolaan Resolusi Konflik Agraria Kawasan Taman Nasional Gunung Gede Pangrango: Sikap dan Strategi Bertahan Petani
Abstrak: Management of conflict resolution has done in the case of expansion in the Village TNGGP Ciputri Block Sarongge Girang cause Sawargi forest farmer group divided into two groups that have been declared out of the claim and the group is still working in the area. This study intends to look at the attitude of the farmer groups and the relationship between the attitude of the farmer groups with survival strategies. The results showed that the attitude of these two categories of farmer groups are equally positive. This shows that social attitudes are formed based on the social facts that apply in Gapoktan Sawargi. Relationship exists only at farmers' attitudes to the level of resistance that has been declared out of the claim. At the level of dependence of the resistance level of tenant farmers and growers who still work there is no relation. This is because the survival strategy decisions arising from upheaval of collective action will land needs of each individual and on the other hand attitude arising from the pressure of prevailing social facts in Gapoktan Sawargi.

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.
