Dlium Big-leaved acacia (Acacia mangium)

Big-leaved acacia has about 142,000 seeds/kg. Long pods form circular threads and are black or brown when ripe. Dry pods will open to expose small black seeds. Trees bind nitrogen to the soil and are a popular species for agroforestry projects.

This plant is weather resistant, although it requires special care if it is planted as a garden plant where the leaves are falling a lot. These plants include legumes that grow quickly by increasing height 4 m per year near the equator, do not require high requirements and are not so affected by soil types.

Strong wood and economic value for finishing and home furnishings including cabinets, door frames, windows and good for fuel. Shiny and smooth surface after polished also to make parquet tiles. A. mangium which is seven years old produces wood that can be made for good particle boards.

The gum contains 5.4% ash, 0.98% N, 1.49% methoxyl, and by calculation, 32.2% uronic acid. The sugar composition after hydrolysis: 9.0% 4-0-methylglucuronic acid, 23.2% glucuronic acid, 56% galactose, 10% arabinose, and 2% rhamnose.

Sengon gall rust (Uromycladium falcatarium)

Sengon gall rust ( Uromycladium falcatarium ) is a species of fungi in Raveneliaceae, grows on molucca albizia ( Falcataria moluccana ) as the host plant, the symptoms vary widely and sometimes are not obvious, the host stem shows brownish lumps to kill slowly. U. falcatarium infects host shoots at the age of 2-3 weeks which causes the leaves to curl, leg, do not develop normally and fall off easily. At 6 weeks of age, symptoms appear on curved and stiff stems and shoots. At the age of 3 months or more the tumor begins to enlarge. Symptoms begin with tumefaction on the leaves, branches and stems. Subsequent development creates a lot of brownish green bumps which then become small rashes on part of the stem or the whole.
