Molucca albizia (Falcataria moluccana)

Sengon laut or Molucca albizia (Falcataria moluccana) is a species of wood-producing trees in Fabaceae, claimed to have the fastest growth in the world with the addition of a height of 7 m/year, producing white light wood for light construction, packing crates, particle boards and blockboards.

F. moluccana has a height of 40 m and a diameter of 100 cm or more, the main stem is generally straight and cylindrical with clear bole up to 20 m. The bark is gray or whitish, smooth or slightly warted with a line of lenticels. Shady canopy, umbrella-shaped and tenuous. Young twigs have sides and hair.

Dlium Molucca albizia (Falcataria moluccana)

Double pinnate compound leaves, small minor leaves, easily fall out with one or more glands on the stem and length 23-30 cm. Leaf fins number 6-20 pairs, each containing 6-26 pairs of elliptical or elongated minor leaves with a very tilted, pointed tip, 0.6-1.8x0.5 cm.

Small flowers, yellowish white, hairy, androgynous, collected in branched panicles, 10-25 cm long and located in the armpit of the leaf. A total of 5, toothed petals with a height of 2 mm. The crown tube is funnel-shaped, white and turns yellow, haired, 6 mm high. Large stamens, white, emerge from a tube and come out beyond the crown.

Molucca albizia produces thin, ribbon-like pods, straight, 6-12x2 cm with a stem length of 0.5-1 cm. The pods break down when they are old and throughout the seam and have 16 seeds or less.

Terrace wood is white or light brown, while sapwood is almost no different from hardwood. Wood has an almost slippery and shiny surface with a somewhat rough and even texture. Fresh wood has a strong odor that gradually disappears after the wood is dry.



Sengon laut has three subspecies: Falcataria moluccana falcataria, Falcataria moluccana salomonensis and Falcataria moluccana fulva. The original habitat is primary forests, but is often found in secondary forests and flood plains on river banks and sometimes in coastal forests.

Generally it is widely planted near settlements, road sides, river banks, fields, paddy fields, tea, coffee and dry fields. Sengon laut also lives in the open and likes clay soil at an altitude of 1650 m. Very fond of wet climates to rather dry and can grow on infertile, stagnant and slightly salty soil.

F. moluccana is classified as light wood, specific gravity is 0.33, strong class IV-V and durable class IV-V. Wood is easily preserved and dried even though fibers that are not straight often occur with bends and twisting. Natural drying of boards with a thickness of 2.5 cm and a moisture content of 20% requires 33 days.

Wood is easily sawed, shaved, shaped, sanded and pulverized. Drilling and making square holes sometimes give unsatisfactory results. Traditionally widely used as boards, rafters, beams, poles and others.

Now commonly used for making boards, packing crates, veneers, pulp, fiber boards, particle boards, blockboards, lighters, footwear, soap crates, household furniture, toy materials, packaging materials and paper. Wood will be more durable and long lasting after being painted and calcined or given other treatments as deemed necessary.

F. moluccana is also often planted as an ornamental plant, shade and shade tree in plantations, erosion control, green manure and firewood. The leaves are used to feed chickens and goats. Bark produces a tanning agent used as mesh.

Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...

Alexandrian Laurel (Calophyllum inophyllum)

Alexandrian Laurel ( Calophyllum inophyllum ) is a species of plant in the Calophyllaceae family. It is a low-branching, slow-growing, spreading tree with a wide, irregular crown. It grows up to 30 meters tall, has a cylindrical trunk, and thick, black, and fissured bark. The leaves are thick, oval, with rounded tips, even margins, and a smooth surface. The upper side is dark green and glossy, the underside is bright green, with a central vein in bright green. The leaves are up to 27 cm long, 13 cm wide, and have a 1 cm petiole. Flowers bloom throughout the year, but typically from April to June and October to December. Flowers are 30 mm in diameter and occur in racemose or paniculate inflorescences of four to 15 flowers. The flowers have a sweet aroma and attract numerous pollinating insects. The fruit is round, green, up to 4 cm in diameter, with a large seed in the center. When ripe, the fruit wrinkles and turns yellow to brownish. The fruit is light, with thin, spongy flesh and a...

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...
