Judul: Etnobotani tumbuhan obat oleh masyarakat sekitar kaki Gunung Salak di Kampung Sinarwangi, Desa Tapos I, Bogor
Abstrak: Tumbuhan yang beranekaragam merupakan sumber utama dalam pemenuhan kebutuhan masyarakat. Pengetahuan mengenai pemanfaatan tumbuhan dikhawatirkan akan hilang seiring dengan perkembangan zaman karena tidak terdokumentasi dengan baik. Penelitian ini bertujuan mempelajari pengetahuan pemanfaatan tumbuhan obat oleh masyarakat di kaki Gunung Salak, Kampung Sinarwangi, Desa Tapos I, Bogor. Metode yang digunakan adalah wawancara kepada satu tokoh kunci dan 20 anggota masyarakat kampung Sinarwangi (responden). Wawancara kepada responden menggunakan metode Pebble Distribution Method (PDM). Hasil penelitian menunjukkan terdapat 46 jenis tumbuhan dari 28 famili yang dimanfaatkan sebagai bahan obat. Tumbuhan-tumbuhan tersebut digunakan untuk mengobati 11 macam penyakit, yaitu hipertensi, hipotensi, kencing batu, luka, menghentikan kebiasaan mengompol, menurunkan kolesterol dalam darah, pegal, perut kembung, sakit gigi, sakit perut, dan setelah melahirkan. Obat tradisional dikemas dalam berbagai bentuk sediaan, seperti segar, larutan, serbuk, tumbukan, dan pepes. Hasil analisis nilai kepentingan lokal menggunakan LUVI diketahui bahwa Staurogyne elongata memiliki nilai tertinggi sebesar 3.51% dan Nilai Kepentingan Budaya (ICS) tertinggi dimiliki oleh Staurogyne elongata, Centella asiatica, Physalis angulata, Coleus atropurpureus, dan Alpinia malaccensis dengan nilai masing-masing sebesar 24.

Judul: Pemanfaatan Tumbuhan Pangan dan Obat Oleh Masyarakat Kampung Sinarwangi di Sekitar Hutan Gunung Salak, Kabupaten Bogor
Abstrak: The needs of food and medicine always increase. The fulfillment of these needs can be met by the utilization of natural resources. Many plant species contains nutrients and essential contents for health and medicinal materials that needs to be explored. Sinarwangi Village is a village around the food of Mount Salak, Bogor. Community of Sinarwangi Village utilize food and medicinal plants directly. Plant untilization which is done by Sinarwangi Village community was closely related to food and health needs in their daily life. The aim of this study is to identify and asses the diversity of food and medicinal plants, also conservation practices in Sinarwangi Village on the utilization of food and medicinal plants. This study was conducted on Mey until June 2012 at Sinarwangi Village by using interviews with a purposive sampling respondent selection as much as 30 respondents. The result of this study showed that there are 79 species from 40 family food plants and 89 species from 47 family identified as medicinal plants from various kind of habitus. The utilization of food plants was dominated by Cucurbitaceae as much as 8 species. Cucurbitaceae family was the main comodity to fulfill the needs of food. The habitus of food plants was mostly tree habitus as much as 30 species. The utilization of medicinal plants was dominated by Zingiberaceae and Fabaceae as much as 8 species. The highest habitus of medicinal plants was herbs habitus as much as 34 species (38%). The knowledge of food and medicinal plants utilization was mostly come from hereditary. The conclusion of this study is that community of Sinarwangi Village utilized plants for food and medicine. Conservation practices such as plant conservation activity, plant cultivation activity and land use. Use of land in Sinarwangi Village includes land use for residential, gardens, fields and forest.

Judul: Kekonsistenan Hamiltonian pada Gerak Gelombang Interfacial
Abstrak: The interfacial wave is an internal wave that occurs at boundary of two layers fluid. It appears because there is difference of mass density between the two layers. The objective of this thesis is to formulate the motion of internal wave with flat base and flat as well as free upper bound surface. The motion equation obtained is a Hamiltonian system. The Hamiltonian in this system is expressed by variable of wave deviation and horizontal component of potential velocity. Under assumption that interfacial wave moves only in one direction, it can be shown that the Hamiltonian depends on the solution of the wave motion equation. The coefficients of the equation depend on the physical characteristics of the two layers of fluid, i.e. thickness and mass density. The numerical results show that Hamiltonian in the system is constant. It is consistent with Hamiltonian characteristic, which does not depend on time.
