Rain tree (Albizia saman)

Trembesi or Ki Hujan or monkey pod tree or rain tree or Samanea saman (Albizia saman) are species in Fabaceae, grow as large trees, tall, umbrella canopies and are very wide, flowering and bearing fruit, roots absorb a lot of water, popular as a shade and scattered throughout the tropics.

A. saman grows 30-40 m, stem diameter is 4.5 m and tree crowns can be 40-60 m wide. Tree trunks are sometimes bent, narrowed or bulging. The bark is grayish brown and smooth when young, but tanned, very rough and peeling when old.

Dlium Rain tree or monkey pod tree (Albizia saman)

The leaves are compound, pinnate bones, flat edges, elongated round shape, 2-6 cm long, 1-4 cm wide, dark green, slippery surface, the bottom has velvety, soft and 7-15 cm long stems. Light sensitive leaves that will close when it rains and at night where the tree is also called the "Tree at 5 pm".

White flowers and pink patches on the upper hair, up to 10 cm long from the base to the ends of the hair. Crown tube measuring 3.7 cm and 20-30 stamens which have a length of 3-5 cm. Nectar to attract insects to encourage pollination. Hundreds of flowers develop simultaneously filling the canopy.

Straight pods slightly curved, hard skin, 10-20 cm long, 1.5-2 cm wide and 0.6 cm thick. The fruit is blackish brown when ripe. Seeds number 5-25 items, length 1.3 cm, ellipsoid, flat, fat embedded in a reddish brown rag, very sticky and sweet.

The striking characteristic of a monkey pod tree is that branches form an umbrella that grows wider than height. A trembesi tree absorbs 28.5 tons of CO2 per year while other tree species only 1 ton of CO2 in 20 years. This tree also decreases gas concentration without greening and absorbs strong groundwater.



Rain tree grow quickly and are spread in the tropics with an average rainfall of 600-3000 mm / year, altitude 0-500 meters, various types of soil with a pH of 4.7 to 8.5 and able to survive 4 months without rain with a temperature of 20 -38C.

Tree trunks are used for building construction materials and leaves are extracted to treat skin diseases. Litter to reduce aluminum concentration, increase pH and absorb nitrogen content for the soil. Seeds are used as a laxative and are processed into nuts.

Ki Hujan Cultivation uses seeds soaked in water at 80C for 1-2 minutes and dried. Then immersed in water at a temperature of 30-40C for 24 hours to accelerate germination up to 90-100%. Sprouts ready for planting have a length of 20-30 cm.

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 ...
