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.

A deep-sea isopod Bathyopsurus nybelini adapted to feed submerged Sargassum algae

NEWS - Incredible footage shows a marine species, Bathyopsurus nybelini , feeding on something that sinks from the ocean’s surface. Researchers using the submersible Alvin found the isopod swimming 3.7 miles down using its paddle-like legs to catch an unexpected food source: Sargassum. Researchers from Woods Hole Oceanographic Institution (WHOI), the University of Montana, SUNY Geneseo, Willamette University and the University of Rhode Island found the algae sinking, while the isopod waited and adapted specifically to find and feed on the sinking nutrient source. The Sargassum lives on the surface for photosynthesis. The discovery of a deep-sea animal that relies on food that sinks from the waters miles above underscores the close relationship between the surface and the deep. “It’s fascinating to see this beautiful animal actively interacting with sargassum, so deep in the ocean. This isopod is extremely rare; only a handful of specimens were collected during the groundbreaking Swedis...

Hairy senna (Senna hirsuta)

Hairy senna ( Senna hirsuta ) is a species of plant in the Fabaceae family. It is an upright shrub, growing up to 2.5 meters tall. The leaves are compound on petioles up to 13 cm long. They usually have 2-6 pairs of leaflets, are egg-shaped, and have white hairs, up to 10 cm long and 5 cm wide. The flowers are yellow and arranged at the tips of branches and in the upper leaf axils in clusters of 2-5. The petals are 12-16 mm long, have 6 stamens, 3-8 mm long anthers, and 4 staminodes. Flowering occurs almost monthly. The pods are cylindrical, up to 15 cm long, 4-6 mm wide, and curved.
