Pinto peanut (Arachis pintoi)

Kacang hias or pinto peanut (Arachis pintoi) are plant species in Fabaceae that grow above the surface of the land, lowlands and highlands in the tropics, very adaptive but prefer to live in the shade rather than being exposed to direct sunlight.

A. pintoi is an annual herb, the stems grow to form a sturdy plait, the roots will grow from the stem if it has direct contact with the soil, has the ability to tether nitrogen from the air and is very well grown as ground cover, fodder, ornamental plants in urban areas and reduce erosion.

Pinto peanut has two pairs of leaves on each stalk, oval shaped for 1.5 cm wide and 3 cm long, producing continuous flowers throughout life for 40-65 flowers per square meter every day. Pollination will push the ovary in the gynophore to extend up to 27 cm and enter the ground up to 7 cm to form a pod that usually contains a seed.

A. pintoi grows and develops well in sub-tropical and tropical regions, annual rainfall is above 1,000 mm and 3-4 months strong dry but it will shed many leaves. Growth will be stunted and the leaves turn yellow if lacking water, frequent flooding and high salt levels.

This plant likes heavy clay to sandy, but grows better on sandy loam. It has a good adaptation to low soil fertility, a very acidic pH and tolerant of high aluminum saturation. Peanut pinto is propagated using seeds, cuttings and stolons.

This plant is often used as erosion control, land rehabilitation, weed control, nematode control including Meloidogyne arabicide and Meloidogyne exigua, to feed cattle, horses, donkeys, sheep, goats, pigs and chickens. The leaves contain high levels of protein and are good for digestion.

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...

Bitter vine (Mikania micrantha)

Sembung rambat or bitter vine ( Mikania micrantha ) is a plant species in Asteraceae, crawling or wrapped around trees, perennial that grows up to 27 mm per day in tropical climates, branched stems where heart-shaped or triangular leaves are arranged in pairs and a plant can cover more than 25 square meters in a few months. M. micrantha has square-shaped stems or longitudinal bones, light green, many branches and has fine hairs. The stems have segments for lengths of 75-215 mm, each segment has a pair of leaves, new shoots and flowers. New roots grow when the segments come in contact with the soil. The leaves are in pairs and facing each other. Strands do not have hair, heart-shaped or triangular with jagged edges, length 30-125 mm, width 15-60 mm. Petiole is 1-6 cm long and has fine hairs. The flower panicle grows from the armpit of the leaf and the tip of the stem, having 3-15 mm long stems. Each flower head has 4 minor flowers. The crown is greenish-white, tubular and measures ...

Cogon grass (Imperata cylindrica)

Alang-alang or cogon grass ( Imperata cylindrica ) is a plant species in Poaceae, annual grass, sharp leaf, long buds and scaly, creeping under the ground, very adaptive and grows in all climates which often become weeds on agricultural land. I. cylindrica has a sharp pointed tip of the bud and emerges from the ground, height of 0.2-1.5 m but in other places it may be more, short stems, rising up to the ground and flowering white or purplish, often with wreath of hair under the segment. Leaf strands in the form of long ribbons, lancet-tipped with a narrow base and gutter-shaped, 12-80 cm long, very coarse edge and jagged sharply, long hair at the base with broad, pale leaf bones in the middle. The flowers are panicles, 6-28 cm long with long-haired and white-colored ears for 1 cm which are used as a tool to blow off the fruit when ripe. Cogon grass breeds quickly with seeds that spread quickly with the wind or through rhizomes that quickly penetrate the soil. Alang-alang does...
