Judul: Manfaat Kampung Konservasi Tumbuhan Obat Keluarga (Toga) Gunung Leutik, Desa Benteng Ciampea Bogor
Abstrak: Revitalisasi konservasi untuk kemandirian kesehatan dapat dicapai dengan pembentukkan kampung konservasi contohnya Kampung Konservasi TOGA Gunung Leutik. Penelitian bertujuan untuk mengidentifikasi manfaat Kampung Konservasi TOGA Gunung Leutik, berupa pemanfaatan tumbuhan obat, dampaknya terhadap kesehatan dan ekonomi masyarakat. Metode pengumpulan data menggunakan wawancara open-ended, studi literatur, dan observasi lapang. Hasil menunjukkan terdapat 152 jenis tumbuhan obat dari 57 famili yang dimanfaatkan, dengan famili tumbuhan obat yang paling banyak digunakan adalah Zingiberaceae dan Asteraceae. Hasil perhitungan Index of Cultural Significance (ICS) menunjukkan jenis yang pemanfaatannya tertinggi, yaitu jahe merah (Zingiber officinale), temulawak (Curcuma xantorrizha), dadap (Erythrina lithosperma), sambiloto (Andrographis paniculata), suji (Dracaena angustifolia), sirih (Piper betle), sembung (Blumea balsamifera), kencur (Kaempferia galanga), lempuyang (Zingiber aromaticum), dan kunyit (Curcuma domestica). Pencanganan Kampung Konservasi Gunung Leutik memberikan dampak positif bagi kesehatan dan ekonomi masyarakat.

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.
