Abstract

Indonesia is known as a country with very high biodiversity, within which are potential medicinal plants that have not been fully explored or utilized. The potential of this natural biodiversity for the health and welfare of  the Indonesian  community  is regarded as high, if it is properly utilized. An example of the potential benefits of these plants is reflected in the types of traditional medicinal plants used by the Mamuju ethnic in West Sulawesi. This research aims to describe the types of plants used as traditional medicines by the Mamuju ethnic group. The study is based on descriptive approach that used a combination of observations, interviews and taxonomy.  The results of the study revealed that there are 31 species of medicinal plants used as sources of traditional medicine by the Mamuju ethnic group, of which there are 33 medical herbs used for the treatment of 31 kinds of diseases. The health issues that are addressed through the use of medicinal plants include the treatment of some types of internal diseases, including cysts, cancer, tumors, high blood pressure, ulcers and diabetes; disease symptoms such as itching, swelling, myopic, new injuries and infections. Some traditional medicines are used in relation to onset of menstruation, and postpartum treatment. The plant components that are used for medicinal purposes include roots, stems, stem bark, leaves, flowers, fruit, seeds, rhizomes and tubers. However, the predominant plant component used for medicinal purposes is plant leaves.

Abstract

Penelitian ini merupakan penelitian deskriptif yang bertujuan untuk menyeleksi (screening) bakteri penambat nitrogen non simbiotik yang diisolasi dari rhizosfer tanaman jagung (Zea mays L.) dan padi (Oryza sativa L.) yang memiliki kemampuan mengekskresikan amonium. Sampel diambil dari daerah Mangkoso, Kabupaten Barru, Provensi Sulawesi Selatan pada daerah rhizosfer tanaman. Isolasi bakteri penambat nitrogen dilakukan dengan menggunakan medium pertumbuhan bebas nitrogen yaitu medium Burk?s dan Ashby. Koloni bakteri yang tumbuh pada medium pertumbuhan selanjutnya dimurnikan dan diuji kemampuan ekskresi amoniumnya dengan menggunakan metode spectrophotometry. Isolat bakteri yang memiliki kemampuan mengekskresikan amonium dikarakterisasi secara morfologi dan fisiologis. Hasil penelitian menunjukkan terdapat 20 isolat bakteri yang mampu tumbuh pada medium bebas nitrogen, namun setelah dilakukan uji ekskresi amonium hanya diperoleh 9 isolat yang memiliki kemampuan mengekskresikan amonium dari masing-masing medium pertumbuhan. Isolat bakteri dan konsentrasi amonium yang diekskresikan masing-masing adalah ABJ211 (179 µg/L), ABP213 (269 µg/L), ABP211 (162 µg/L), ABP131 (254 µg/L), ABP242 (104 µg/L), BBJ221 (263 µg/L), BBJ222 (272 µg/L), BBP222 (269 µg/L) dan BBP214 (257 µg/L). Kesembilan isolat tersebut memiliki karakteristik morfologi dan fisiologis yang bervariasi terutama pada sifat struktur dinding sel (gram), kemampuan hidrolisis pati, gelatin dan kasein, sementara kemampuan dalam mereduksi nitrat dan H2O2 (reaksi katalase positif) serta fermentasi glukosa menunjukkan karakter yang seragam.Kata kunci: Bakteri Penambat Nitrogen, Non Simbiotik, Ekskresi Amonium, Karakterisasi Morfologi dan Fisiologis
