Tall reed (Phragmites karka)

Prumpung or tall reed (Phragmites karka) is a species of plant in the Poaceae, grass with large, hollow stems, chronic, often found growing in damp places, forming dense colonies and used for crafts to support and firewood.

P. karka has chronic reeds with spreading rhizomes and erect stems up to 10 m high, hollow and young shoots grow to form branches on the segments.

The tip has a soft stem and is green with linear stripes and is covered with leaves. The base has a hard stem, woody, bare and yellow or brown or black.

The leaves are ribbon-shaped, 30-80 cm long, 12-40 mm wide and green. The flowers are clustered in panicles, 30-50 cm long, 10-20 cm wide and 9-12 mm spikelets. Generally reproduce vegetatively and rarely flower.

Tall reed grows at elevations near sea level up to 3000 meters along river banks, marshes, wet meadows, mountain slopes and is flood resistant. Widely planted for soil stabilization from erosion. Split tatepal trunks are used instead of bamboo to make roofs and woven materials.

Thomas Sutikna lives with Homo floresiensis

BLOG - On October 28, 2004, a paper was published in Nature describing the dwarf hominin we know today as Homo floresiensis that has shocked the world. The report changed the geographical landscape of early humans that previously stated that the Pleistocene Asia was only represented by two species, Homo erectus and Homo sapiens . The report titled "A new small-bodied hominin from the Late Pleistocene of Flores, Indonesia" written by Peter Brown and Mike J. Morwood from the University of New England with Thomas Sutikna, Raden Pandji Soejono, Jatmiko, E. Wahyu Saptomo and Rokus Awe Due from the National Archaeology Research Institute (ARKENAS), Indonesia, presents more diversity in the genus Homo. “Immediately, my fever vanished. I couldn’t sleep well that night. I couldn’t wait for sunrise. In the early morning we went to the site, and when we arrived in the cave, I didn’t say a thing because both my mind and heart couldn’t handle this incredible moment. I just went down...

Purwaceng (Pimpinella pruatjan)

Purwaceng or purwoceng or antanan gunung or Viagra of Java ( Pimpinella pruatjan or Pimpinella priatjan ) are small termas growing horizontally in Apiaceae, growing in villages on Dieng Plateau, Central Java Province, Indonesia, at 1,500 to 2,000 meters above sea level, the roots have medicinal properties for aphrodisiacs and are usually processed in powder form for a mixture of coffee or milk. P. pruatjan grows flat on the ground but does not propagate, small leaves are reddish green for 1-3 cm in diameter. This plant is only found in Java and grows in high mountain areas. A low population where industrial demand is very high results in increasingly scarce. Another place that is likely to become a purwaceng habitat is the Iyang Mountains and the Tengger Mountains in East Java Province. Efforts to multiply and cultivate have a big problem where these plants have difficulty producing seeds. In vitro propagation research through tissue cultivation has been carried out to overcome ...
