Judul: Study of Potency of Plant Medicinal for Enrichment of Items of Study at school Regency Cianjur
Abstrak: In Regency Cianjur of there are various type ecosystem forest, start from coast until the mountain which lay away drug plant type variety which immeasurable enough and the industrial amount of traditional drug (Industry Medicinal Small Traditional /IOT Industry and Medicinal Traditional/ IKOT) as much 6 (six) unit, but the plant potency medicinal in the region to date not yet been known. On the other side, do not all grad Elementary school, Junior high school, and Senior high school in the region continue school to ladder hereinafter or higher. In order to grad Elementary school, Junior high school, and Senior high school which do not become unemployment, hence to student at school require to be supplied with items which can make grad own efficiency live and able to enterpreneur. One of items which can be accommodated is about plant medicinal. In order to supporting efficacy in information exploiting of about plant potency medicinal for the study items enrichment at school Regency Cianjur, hence this research require to be done. This research aim to to determine plant potency medicinal in Regency Cianjur information exploiting elegibility and of about plant potency medicinal for the study items enrichment at school. Research method is marginally consisted of by 4 (especial four) activity, that is data collecting (secondary data and primary), identify drug plant type, data processing, and analyze data. Pursuant to result of research indicate that in Regency of Cianjur of there are type of plant medicinal as much 210 type from 83 set of relatives. From the amount can be grouped by into 32 group of disease/ use and 6 (six) of kinds of habitus, that is tree, herba, clump, liana, bamboo, and the moss. type Plant of preeminent drug [is] which is there are in Regency of Cianjur as much 11 type and which can be developed in each subdistrict range from 6-11 type. Eleventh of type plant of the drug is Pulai/ Lame (Alstonia Scholaris R.Br.), Pulasari (Alyxia Reinwardtii Bl.), Cardamom (Amomum Compactum Soland. ex Maton.), Sambiloto (Andrographis Paniculata ( Burm.F.) Wall. ex Nees.), Ki Koneng (Arcangelisia Flava Merr.), Encounter Key (Boesenbergia Pandurata ( Roxb.) Schlet.), Secang (Caesalpinia Sappan Linn.), Cecenet/ Antanan Gede (Centella Asiatica Urb.), Encounter Ireng (Curcuma Aeruginosa Roxb.), Fennel (Foeniculum Vulgare Mill.), and Alpine Galanga (Languas Galanga ( L.) Stuntz.). Pursuant to drug plant potency which is there are in Regency Cianjur, invitation regulation and policy, and also support stakeholder is inclusive of competent or adequate but from facet human resource being, and also the and medium not yet competent or adequate. Strategy which can be applied to utilize to improve elegibility in information exploiting of about plant potency medicinal for the study items enrichment at school Regency Cianjur, covering : study model of through band curicular and extracurricular, human resource quality being improvement, and ready and medium adequately.

Judul: Potensi Tumbuhan Obat di Desa Gunungsari, Kecamatan Sukanagara, Kabupaten Cianjur, Jawa Barat
Abstrak: Penggunaan tumbuhan obat masih sering dijumpai pada komunitas masyarakat sekitar hutan. Desa Gunungsari memiliki hutan yang dikelola oleh Perum Perhutani dimana masyarakat ikut terlibat dalam praktiknya. Aktivitas masyarakat di hutan mengindikasikan adanya pemanfaatan tumbuhan obat, namun belum diketahui bagaimana bentuk pemanfaatannya. Penelitian ini bertujuan untuk menganalisis keanekaragaman tumbuhan yang ada di hutan desa lalu mengidentifikasi tumbuhan obat dan potensi pengembangannya. Penelitian dilaksanakan dari November 2022 - Januari 2023 di Desa Gunungsari. Metode pengumpulan data menggunakan studi literatur, wawancara, serta analisis vegetasi digunakan untuk mencari data pemanfaatan oleh masyarakat, keanekaragaman vegetasi, serta potensi tumbuhan obat. Hasil menunjukkan terdapat 66 cara pemanfaatan tumbuhan obat oleh masyarakat, ditemukan 53 spesies dari 43 famili tumbuhan di hutan dengan 42 spesies diketahui memiliki khasiat obat, serta 10 diantaranya memiliki potensi untuk dikembangkan. Kata kunci: pemanfaatan, potensi, tumbuhan obat, The use of medicinal plants is still prevalent within forest communities. Gunungsari Village hosted a forest managed by Perum Perhutani, which involves community participation. The specific methods of how the people utilizing medicinal plants remain unclear. This research aims to analyze the botanical diversity within village forests and identify their medicinal potential. Carried out from November 2022 to January 2023 in Gunungsari Village, the research collected data through literature reviews, interviews, and vegetation analysis. This research revealed that the community employed 66 different methods of utilizing medicinal plants. There were 53 species from 43 different plant families identified, of which 42 were recognized for their medicinal properties. Furthermore, 10 of these species were identified as having significant potential for further development. Keywords: medicinal plants, potential, utilization

Judul: Formulasi Hamilton Untuk Menggambarkan Deformasi Gelombang Soliter Dengan Dasar Tidak Rata Pada Fluida Dua Lapisan
Abstrak: Gelombang internal adalah suatu gelombang yang muncul di bawah permukaan laut sehingga gelombang ini tidak teramati secara kasat mata. Formulasi Hamilton dirumuskan untuk menjelaskan gerak gelombang ini. Dalam hal ini diasumsikan bahwa fluida yang ditinjau terdiri atas dua lapisan dengan masing-masing lapisan memiliki rapat massa yang konstan. Selain itu, diasumsikan pula fluida yang ditinjau berupa fluida tak mampat (incompressible) dan tak kental (invicid). Formulasi Hamilton dilakukan dengan meninjau fluida dua lapisan yang berada pada domain yang dibatasi oleh batas atas yang rata dan batas bawah yang tidak rata. Hamilton (energi total)-nya didefinisikan sebagai penjumlahan antara energi kinetik dan energi potensialnya. Karena energi kinetik tidak secara eksplisit dinyatakan dalam peubah fisis, maka digunakan metode asimtotik untuk menentukan energi totalnya. Dalam hal ini diasumsikan bahwa gelombang interfacial yang ditinjau cukup panjang, dan amplitudo yang cukup kecil. Persamaan Korteweg de- Vries (KdV) diperoleh, jika disumsikan bahwa gelombang interfacial hanya merambat pada satu arah, sedangkan jika gelombang tersebut merambat ke dua arah, diperoleh persamaan Boussinesq.
