Usability and Benefits of Wood Sengon
Sengon tree is a multipurpose tree. From the start of the leaves to roots can be utilized for various purposes.
leaves
classified as a family Mimosaceae. The leaves can be used as an excellent animal feed and high protein for livestock such as cows, buffaloes, and goats. Form of pinnate leaves and compound leaves to 40 cm, composed of 8-15 pairs. The leaves consist of 15-25 leaves per branch. _ The color of dark green leaves, serves to cook the food with the help of sunlight and also serves to absorb nitrogen and carbon dioxide from the air.
Rooting
Sengon root system contains a lot of root nodules as a result of symbiosis with Rhizobium bacteria. This is beneficial for the roots and surrounding areas. The presence of root nodules and soil porosity can help openyediaan elemental nitrogen in the soil. Thus sengon tree can make the surrounding soil becomes more fertile. Further land may be planted with crops so as to increase farmers' income penggarapnya.Sengon have strong enough roots ridingpenetrate into the soil, the roots of her hair is not too big, not dense anddoes not protrude to the surface soil.Hair root function to store the substances nitrogen, therefore the soilsengon around the tree to be fertile.
Interest
Sengon plant flowers arranged in a paniclemeasuring about 0.5 to 1 cm, yellowish white in color and slightlyhairy. Every flower blooms consist of male flowers and female flowers,in a way that assisted pollinationby wind or insects.
Fruit
Sengon shaped fruit pods, flat, thin, notsectional and a length of about 6-12 cm. Each pod contains 15 pieces -30 seeds. Small shield-like form of seeds, green when young and whenold seeds will turn yellow to blackish brown, rather hard,and waxy.
Seedlings sengon
Seeds
Flat, oval, 3-4 x 6-7 mm, green,the center of the chocolate. The number of seeds 40 000 eggs / kg. The average germination80%. 1000 grain weight of 16-26 grams.
Timber
Sengon good quality
Sengon with care is quite goodSection that provides the greatest benefit from the stem wood of trees sengon. The price is quite tempting now sengon much cultivated for various purposes in the form of a board of wood boards with a certain size as a raw material coffin maker, board blockers, casting of cement in the construction industry, matches, pencils, particle board, pulp raw material paper etc.. Is a multi-purpose timber for light construction, handicrafts, cigar boxes, veneer, plywood, matches, musical instruments, pulp. Leaves as food for chickens and goats. In Ambon bark used for tanning nets, sometimes as a substitute for soap. Planted as shade trees, ornamental plants, reforestation and afforestation.
Anatomy
Botanical name: (Paraserianthes)falcataria (L) Nielsen), syn. Albizia falcata Backer,family Mimosaceae. Local name: Albizia, bae, bai, jeungjing, jeungjing sea,jing sea, rare, salawaku, salawaku red, white salawaku, salawoku, insulation,sengon sea, sengon Sabrang, Sika, Sika bots, cycads, laughter interrupted, wai, wahagom,Another wiekkie.Nama: Batai (West Malaysia, Sabah, Filipinos, British, AmericanStates, France, Spain, Italy, Netherlands, Germany); wood Machian (Sarawak);puah (Brunei). Distribution: The whole of Java, Maluku, Irian Jaya.Common trait: wood porch is almost white or brown in colorpale (like meat) color are generally no different pig wood to woodterrace. Its texture is rather coarse and uneven with the direction of the fiber is straight, wavywidth or chime. Wood surface is rather smooth and somewhat shiny and smooth.The wood is still fresh smelling banana, but the smell is gradually lost ifthe wood becomes dry. Properties of wood: Wood preserved sengon including class IV / V andclass IV-V with a specific gravity of 0.33 (0.24 to 0.49). The wood is soft and has adepreciation in the value of the radial and tangential directions respectively 2.5 percent and5.2 percent (wet to dry kiln). The wood is easily sawed, but notas easy as red meranti wood and can be dried quickly without disabilities whomeans. Common defect is a wood drying curve or twist.(Martawijaya and Kartasujana, 1977).
Comparative Study of Sampling Methods Drill with Disk untukPengukuran increment and the proportion ofWood fiber dimension Sengon Salomon (Paraserianthes falcataria, (L.) Nielsen)Increment method is to use drill and method of disknot give a real difference to the measurement of fiber dimensions. Similarly, the proportion of cells also did not make a differencereal as a result of differencesusing the two methods. Locationposition of wood in the radial direction does not give a real difference to themeasured the proportion of cell types. For the fiber dimensions are as follows variation of fiber length was significantly different in the directionradial, where the length of the fiber close to the skin longer thannear the liver, as well as for the thick cell walls of wood. Fiber diameter and lumen diameter did not differreal wood in radial direction (Praptoyo, 2005)
