Judul: Partisipasi masyarakat dalam Program Gerakan Nasional Rehabilitasi Hutan dan Lahan (GN-RHL) kasus di Desa Sirnagalih dan Pamalayan, Kecamatan Bayongbong serta Desa Margaluyu dan Ciburial, Kecamatan Leles, Kabupaten Garut
Abstrak: Kegiatan GN-RHL tidak akan pernah berhasil tanpa didukung oleh partisipasi masyarakat, karena keberhasilan suatu kegiatan pembangunan akan sangat ditentukan oleh adanya partisipasi masyarakat. Partisipasi masyarakat dalam kegiatan GN-RHL diharapkan memiliki arti yang besar, oleh karena itu diharapkan pada masyarakat akan dapat menumbuhkan rasa memiliki, rasa tanggung jawab dan merasakan adanya manfaat yang diperoleh dari kegiatan GNRHL tersebut. Perkembangan tanaman GN-RHL dapat dijadikan sebagai salah satu indikator keberhasilan program GN-RHL. Penelitian ini bertujuan untuk mengetahui tingkat partisipasi petani peserta GN-RHL, mengetahui perkembangan tanaman GN-RHL, dan menganalisis hubungan karakteristik petani dengan partisipasi petani dalam GN-RHL.

Judul: Development Of Community Participation In Land And Forest Rehabilitation Movement; Case In sub-District Of Layana East Palu And Sub-District Of Lambara North Palu In Palu Regency, Central Sulawesi
Abstrak: This research generally aimed to study the level of community participation on GN-RHL programs, relations among factors that influencing participation with level of community participation, and also making the strategy of development of community participation in GN-RHL. Method which applied is consisting of descriptive-quantitative and descriptive-qualitative by using Spearman Rank test, and SWOT analysis (Strength, Weakness, Opportunity, and Threat). In both reaserch location, Layana and Lambara, level of participation at evaluation and planning phase pertained is low, while at execution phase, pertained height. Community participation in both location of admission in passive participation, where community only receiving notification of result which have been decided by the side of program executor, regardless of community comments as programs targets, and interchangeable information limited to outsider group. Strategy development of community participation in GN-RHL programes to be done with strategy WO (Weakness - Opportunitiess) that is to improve internal weakness and exploiting opportunity from external environment.

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.
