Judul: Kajian Pemanfaatan Tumbuhan Obat Keluarga di Kampung Babakan-Cengal Desa Karacak Kecamatan Leuwiliang, Kabupaten Bogor
Abstrak: Tumbuhan obat merupakan alternatif bahan obat bagi pemenuhan kesehatan berbagai kalangan masyarakat di Indonesia. Masyarakat Kampung Babakan-Cengal telah lama memanfaatkan tumbuhan obat yang terdapat di sekitar lingkungan rumahnya dalam mengobati penyakit yang dideritanya. Pemanfaatan tumbuhan berkhasiat obat yang telah dilakukan oleh masyarakat tersebut harus dilestarikan. Tujuan penelitian ini adalah untuk mengkaji: (1) Potensi tumbuhan obat di Kampung Babakan-Cengal yang bisa dikembangkan untuk meningkatkan kesehatan keluarga secara mandiri, dan (2) Pengetahuan, pemanfaatan, dan kegiatan budidaya tumbuhan obat keluarga (TOGA) di Kampung Babakan-Cengal sebagai sarana pengobatan dan pemeliharaan kesehatan keluarga. Penelitian ini dilakukan pada bulan Juli sampai Agustus 2011 di Kampung Babakan-Cengal Desa Karacak Kecamatan Leuwiliang, Kabupaten Bogor. Metode yang digunakan adalah studi pustaka, survei potensi tumbuhan obat keluarga (TOGA), dan wawancara. Pemilihan responden dilakukan menggunakan teknik snowball dengan jumlah responden 30 orang. Sedangkan survei potensi tumbuhan obat dilakukan secara sensus. Analisis data dilakukan secara kuantitatif dan kualitatif yang selanjutnya dianalisis secara deskriptif.

Judul: Pengembangan Tumbuhan Obat Keluarga Melalui Peran Serta Masyarakat (Studi Kasus di Kampung Gunung Leutik Desa Benteng, Kecamatan Ciampea Bogor)
Abstrak: Health is a crucial aspect to reach family and social welfare. Unfortunately, it is still difficult for some people to access health services and modern medicines. The alternative solutions are needed to solve health problems. One of the best solutions is back to the nature by consuming natural medicines obtained from medicinal plants, which is relatively safer and cheaper. Therefore people need to understand about the potencies and benefits of medicinal plants surround them in order to build community’s interest on natural medicines and develop family’s medicinal plants. The objective of this research is identifying the medicine plant potency which can be developed to increase the family health independently, searching knowledge, using and cultivating the family’s medicinal plants as a medicine facility and family health preservation. This study was conducted during May until June 2009 in Gunung Leutik Village, Ciampea Subdistrict, Bogor. Materials and tools that were used such documents from certain institutions; map; camera; questioner related to the community’s knowledge, utilization and cultivation of medicinal plants and writing equipments. This research was conducted in May until June 2009 at Kampung Gunung Leutik, Benteng Village, Kecamatan Ciampea, Bogor. Materials and devices that needed in this research are: documents from many instances, map, camera, questionnaire for citizen of Gunung Leutik in the relationship with knowledge, usage and cultivation of medicine plant, writing tools. Gunung Leutik Village possesses big medicinal plants potencies that consist of 216 species, 70 family spread at 6 RT. Based on habitat typology, the potencies of medicinal plants are mostly found at house yards and gardens. The habitus is dominated by herbs. Leaves and roots are parts of plants that mostly used. The potencies of medicinal plants in Gunung Leutik village are able to be used for treating 25 kinds of illness. The potencies of medicinal plants are not used optimally yet. Out of 216 species of medicinal plants, only 45, 37% was known by people, 21, 76% was usually used and 26, 85% was cultivated. One of solution to develop family’s medicinal plants is cultivating important medicinal plants. It is hopefully, the family’s medicinal plants will be used properly to maintain family’s and community’s health toward better quality of life.

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.
