The bark is slightly smooth, dark grey outside, with transverse bark lines, lenticels, thin; 5 mm inner bark thickness, pink. The young branches are faceted and hairy.<\/p>\n<p style=\"text-align: justify\">Double-pinnate compound leaves, with 4\u201314 pairs of stipules; 10\u201325 cm long petiole, hairy, with glands near the petiole\u2019s base and at the stipules\u2019 junction. The stipules are large, oblique ovate with a half-heart-shaped base, membrane-like, with a tail at the end, and easily fall off. The veins are pinnate 4\u201314 cm long, with 10\u201345 leaflets per vein, seated, opposite. The leaflets elongate to a striped shape, with a pointed tip, oblique, blue-green underside, 6\u201313 \u00d7 1.5\u20134 mm, and the midrib is very close to the upper edge.<\/p>\n<p style=\"text-align: justify\">Compound flowers form a stemmed hump, recollected into panicles 15\u201330 cm long. The hump contains 10\u201320 flowers . The flowers are 5-petaled, with toothed calyx, lk 4 mm height, hairy; funnel-shaped crown tube, yellow-green, lk 7 mm height, hairy. It contains ten stamens or more, about 3 cm long, white and green above, fused at the base to form a tube approximately as high as the crown. The pods are 10\u201318 cm \u00d7 2\u20133.5 cm long, unopened, and irregularly broken. Flat shape seeds, ellipse, 7 \u00d7 4\u20135 mm in size.<\/p>\n<p style=\"text-align: justify\"><strong>Ecology and Distribution<br \/>\nLegumes<br \/>\n<\/strong>Sengon is found naturally in mixed deciduous forests in humid and moderate areas, with rainfall between 1,000\u20135,000 mm per year. We can also find this tree growing in secondary forests, along the river banks, and in the savanna, up to an altitude of 1,800 m above sea level. Sengon is well adapted to poor, high pH \u200b\u200bor salty soils and grows well on lateritic alluvial and ex-mining sandy soils.<\/p>\n<p style=\"text-align: justify\">The natural distribution of sengon includes India, Burma, Thailand, Cambodia, Laos, China, Vietnam, and Indonesia, introduced to Australia. In Indonesia, sengon spreads in Java, Bali, and Nusa Tenggara brought in and cultivated in Sumatra and Kalimantan.<\/p>\n<p style=\"text-align: justify\"><strong>Benefit<br \/>\nWood<br \/>\n<\/strong>Sengon produces light to moderately light wood, with a density of 320\u2013640 kg\/m\u00b3 at a moisture content of 15%[8]. Slightly dense, straight-grained and a bit rough, but easy to work with. The heartwood is a glossy yellow to ivory-brown; its strength and durability are classified into solidity class III-IV and durability class III-IV. Subterranean termites do not attack this wood due to the presence of extractive substances in the wood. However, burial experiments in the Philippines found that sengon wood (<em>A. Chinensis<\/em>) lasts only 16 months, while\u00a0<em>langir<\/em>\u00a0wood (<em>A. Saponaria<\/em>) lasts up to 3 years and\u00a0<em>weru<\/em>\u00a0wood (<em>A. Proc<\/em>era) lasts up to 10 years.<\/p>\n<p style=\"text-align: justify\">Sengon wood is commonly used to make crates, boats, houses and bridges compound [4]. In Sabah,\u00a0<em>A. Chinensis<\/em>\u00a0wood is traded as\u00a0<em>\u2018batai\u2019<\/em>\u00a0wood, in combination with\u00a0<em>A. Pedicellata<\/em>\u00a0and\u00a0<em>Paraserianthes falcataria<\/em>.<\/p>\n<p style=\"text-align: justify\"><strong>Agroforestry<br \/>\n<\/strong>In coffee and tea plantations,\u00a0<em>A. Chinensis<\/em>\u00a0is often grown as shade, especially in mixtures with\u00a0<em>jeunjing<\/em>\u00a0(<em>P. Falcata<\/em>ria) and\u00a0<em>dadap<\/em>\u00a0(<em>Erythrina spp.<\/em>). Sengon is favoured as an ornamental plant and shade in gardens, farms, and roadsides. This tree is also planted to protect sloping land and also improve the soil.Sengon roots are nitrogen fixing.<\/p>\n<p style=\"text-align: justify\"><strong>Other uses<br \/>\n<\/strong>Essentialy like the bark of\u00a0<em>ki hiang<\/em>, sengon bark contains ingredients we can use to anesthetize fish in rivers. In the past, this bark was also used as an ingredient of soap.<\/p>\n<p style=\"text-align: justify\">Although goats can eat the leaves, the bark of the branches is poisonous because it contains saponins.<\/p>\n<p style=\"text-align: justify\"><strong>Similar type<br \/>\n<\/strong>The stature and wood of\u00a0<em>Paraserianthes Falcataria<\/em>\u00a0are more or less similar to that of the sengon tree and wood, so their names are often interchanged. By the Javanese,\u00a0<em>P. Falcataria<\/em>\u2014originally from Maluku\u2014is called\u00a0<em>sengon laut<\/em>,\u00a0<em>sengon sabrang<\/em>, or\u00a0<em>sengon landi<\/em>.<\/p>\n","protected":false},"featured_media":275553,"template":"","unit_bisnis":[2],"class_list":["post-106","product","type-product","status-publish","has-post-thumbnail","hentry","unit_bisnis-kayu"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.perhutani.co.id\/en\/wp-json\/wp\/v2\/product\/106","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.perhutani.co.id\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.perhutani.co.id\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.perhutani.co.id\/en\/wp-json\/wp\/v2\/media\/275553"}],"wp:attachment":[{"href":"https:\/\/www.perhutani.co.id\/en\/wp-json\/wp\/v2\/media?parent=106"}],"wp:term":[{"taxonomy":"unit_bisnis","embeddable":true,"href":"https:\/\/www.perhutani.co.id\/en\/wp-json\/wp\/v2\/unit_bisnis?post=106"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
