Abstract

The current utilization of natural materials as a traditional medicine in Indonesia. Aquatic plants has potential as a traditional medicine because it contains active ingredients that are good for health, one of them namely, Padina australis Hauck.The purpose of this study is to establish the most effective concentration of extract of Padina australis as Vibrio cholerae antibacterial and Salmonella typhi. Extract of Padina australis is made by maceration method. Test of the effectivity of extract of Padina australis against Vibrio cholerae and Salmonella typhi. Disc diffusion method Kirby Bauer at the treatment the extract concentration of 50%, 60%, 70%, 80% and control. Results of testing the extract Padina australis against Vibrio cholerae showed a concentration of 80% is the concentration forming the greatest drag areas namely 19.48 mm, while the test results against Salmonella typhi bacteria extract at concentrations of 80% obtained a diameter drag area of 12 mm.Key words : antibacterial, Padina australis Hauck, Vibrio cholerae, and Salmonella typhi.

Abstract

Some of the various flora that Indonesia has is the diversity of fungi, lichens and moss. Taman natural tourism Situgunung is one place that is suitable for mushrooms. The study was conducted at an altitude of 950 m above sea level, 990 m above sea level and 1050 m above sea level. Each height is made of three transect lines with a length of each 100 m transect with a total plot of 90 plot samples. Each transect is made of 10 sample plots measuring 1 x 1 m with a spacing between 10 m. The important value index (INP) that dominates each height is Marasmius copelandi, the height of 990 m above sea level is Stereum ostrea, and the Important Value Index at an altitude of 1050 is Stereum sp. Diversity index of fungal species in the TWA Situgunung area is high with an average value of 3.78.Key words : Situgunung, fungi, index diversity

Abstract

The research Diversity and Potential paku (Pteridophyta) in The Taman Nasional Gede Pangrango Montain Cianjur have been done. Transek and plot sample method use in this research on three area of different altitude (1600, 1900, 2200 m above sea level). The result research show there were 56 species of ferns that include in 21 families. At an altitude of 1600 m above sea level diversity ferns include in the medium category with value 1,48, at an altitude of 1900 m above sea level diversity ferns include in the medium category with value 1,02, and altitude of 2200 m above sea level diversity ferns include in the low category with value 0,93. Ferns in the TNGGP have potensial for the surroundings communities Kebun Raya Cibodas.Key words : Ferns, diversity, Gede Pangrango Mountain.

Abstract

Jamur Fusarium oxysporum merupakan patogen yang dapat menyebabkan penyakit busuk batang pada tanaman vanili. Adanya pembusukan pada jaringan batang tersebut merupakan ciri khas dari penyakit busuk batang. Gejala khas dari serangan patogen pada pangkal batang mengakibatkan pangkal batang menjadi berwarna hitam. Salah satu cara untuk mengendalikannya yaitu menggunakan agen pengendali hayati berupa bakteri antagonis. Tujuan dari penelitian ini untuk mendapatkan satu isolat bakteri antagonis yang paling efektif menekan pertumbuhan koloni serta perkecambahan konidia dan zoospora patogen Fusarium oxysporum dan Phytopthora capsici. Penelitian dilakukan secara in vitro, tahapan kegiatan dalam penelitian ini meliputi sterilisasi alat, pembuatan media, pembuatan inokulum, pengujian antagonis isolat bakteri dan filtratnya serta pengamatannya. Bahan yang digunakan adalah isolat F.oxysporum, P.capsici dan sembilan isolat bakteri. Hasil penelitian menunjukkan bahwa dari sembilan isolat bakteri terdapat satu isolat bakteri paling efektif menghambat pertumbuhan patogen F.oxysporum yaitu isolat bakteri AKT7 sebesar 29,91% sedang isolat bakteri paling efektif menghambat patogen P.capsici yaitu isolat bakteri B5A sebesar 54,42% . Filtrat bakteri AKT7 mampu menghambat perkecambahan konidia F.oxysporum dan zoospora P.capsici.Kata kunci : Fusarium oxysporum , Phytopthora capsici, bakteri antagonis
