FOREIGN NAME: Cogon grass, satintail (En). Paillotte (Fr). Malaysia: thatch, reed. Papua New Guinea: Kunai (Pidgin), Kurukuru (Barakau, Central Province). Philippines: Kogon (Tagalog), gogon (Bikol), bulum (Ifugao). Burma (Myanmar): kyet-mei. Cambodia: SBO ': w. Laos: hnha: z kh'a:. Thailand: yes-kha, laa laeng, koe hee (Karen, Mae Hong Son). Habitat: Grow at elevations up to 2700 m above sea level, in areas open or half-closed; marshes; in soil with good aeration; in areas which open out; riverside; extensive secondary forest; area burned; as a weed in cultivation; gardens and plantations. This plant can affect plant cultivation, because the relatively high sodium needs. Description: Alang-alang (Imperata cylindrical (L.) Beauv.var.mayor ), Stature: herbs, grass, edging, 30-180 cm tall. Trunk: rhizome, creeping underground stems forming an inflorescence erect, dense, sparse hair on his book. Leaves: single, base close to each other, strands; ribbon-shaped, sharp pointed tip, straight, coarse, sparse hair, size 12-80 cm. x 35-18 cm. Flowers: composition compound compound grains, rather furl, 6-28 cm long, each branch has 2 ears, 2,5-5 cm branches, flower stalks 1-3 mm, gluma 1; tip of ciliated, 3-6 veins, Lemma 1 (chaff); wide oval, short cilia 1.5-2.5 mm. Lemma 2 (chaff); elongated, tapered 0.5-2.5 mm. Palea (Husk); 0.75 to 2 mm. Stamens: anthers 2.5-3.5 mm, yellowish white or purple. Pistil: quill-shaped anthers. Fruit: type of rice. Seeds: elliptic, 1 mm long. Flowering time: January-December. Regional distribution, Habitat and Cultivation: In Java grows at altitudes up to 2700 m above sea level, in the areas of open or half-closed; marshes; in soil with good aeration; in areas which open out; riverside; extensive secondary forest; area burned; as a weed in cultivation; gardens and plantations. This plant can affect plant cultivation, because the relatively high sodium needs. Multiplication: multiply by itself. Every time the rhizomes are harvested from plants that have matured. Pale-colored rhizome good, taste sweet and cool. Reeds can cause a decrease in soil pH. The magnitude of the decrease in pH and barriers to the process of nitrification showed a positive correlation with the growth of reeds The content of Alang-Alang: Roots: metabolites have been found in the roots of reeds consists of arundoin, fernenol, isoarborinol, silindrin, simiarenol, kampesterol, stigmasterol, ß-sitosterol, scopoletin, skopolin, p-hidroksibenzaladehida, catechol, chlorogenic acid, isoklorogenat acid, p- kumarat, neoklorogenat acid, acetic acid, oxalic acid, d-malic acid, citric acid, potassium (0.75% of dry weight), a large amount of calcium and 5-hydroxytryptamine. From the results of other studies on the roots and leaves found 5 different flavonoid derivatives ie derivatives 3 ', 4' ,7-trihydroxy flavones, 2 ', 3'-dihydroxy kalkon and 6-hydroxy flavanol. A flavonoid derivatives that likely belonged to the flavones, flavonols substituted 3-0H, flavanones or isoflavones contained in the soluble fraction of the ethyl acetate extract of the roots of weeds. In the fraction of water-soluble extract of the roots of weeds class of flavonoids found no free OH groups, flavones, flavonols substituted 3-0H, flavanones or isoflavones. Efficacy of Reeds: Efficacy reeds are: Parts used for medical drugs is the root. In fact, its roots can be used to lower the temperature, launched urine, stop bleeding, and as a remedy for nose bleeding, vomiting blood, gonorrhea (gonorrhea), hepatitis, kidney infections. The study found that the reeds containing mannitol, glucose, malic acid, citric acid, coixol, arundoin, silindrin, fernerol, simiarenol, anemonin, achine, alkali, saponins, taninin, and polyphenols. Alang-Alang traditional recipe: As urine laxative: 49 pieces dried rhizome, cut into pieces and then coupled with 2 cups of water and boiled until the volume of water to 1 cup, filtered, then taken 2 times a day. Fever bloody urination: 1 spoon full of reed rhizome, boil with a few pieces of pliers kwe (half-ripe fruit flesh beligu made candied dried) in two glasses of water to stay half. This drink 2 cups water 1 day. Urine will be normal and the body temperature down. "Zwartwaterkoorts" (Bld): Drink boiled water as tea alang alang roots.
