Chinese albizia (Albizia chinensis)

Sengon or Chinese albizia (Albizia chinensis) is a species of plant in the Fabaceae, shade and wood-producing tree, deciduous, 30-45 m high, 70-140 cm in diameter, slightly smooth bark, dark gray with transverse teeth, lenticels, thin, faceted and hairy young branches.

A. chinensis has compound leaves, multiple pinnate and 4-14 pairs of fins. The main leaf bone is 10-25 cm long, hairy with glands near the base of the petiole and at the junction of the fin bones. The cusps are large, ovate with a heart-shaped base, like a membrane with a tail at the end.

Dlium Chinese albizia (Albizia chinensis)

The leaf fins are 4-14 cm long with 10-45 leaflets per fin, sitting and facing each other. Leaflets are elongated to form a line with a pointed tip, oblique, blue green underside, 6-13 mm long, 1.5-4 mm wide, the middle leaf bone is very close to the top edge.

Compound flowers, hump-shaped, stemmed, collected again into panicles with a length of 15-30 cm. The hump has 10-20 buds. Toothed petals, 4 mm high and hairy. The crown tube is funnel-shaped, yellow-green, 7 mm high and hairy. Stamens numbered 10 or more, 3 cm long, white, top green, base fused to form a tube, approximately as high as the crown.

The pod-shaped fruit is 10-18 cm long, 2-3.5 cm wide, does not open, breaks irregularly. Seeds are flat, oblong, 7 mm long and 4-5 mm wide.

Sengon is found naturally in mixed deciduous forests in humid and sunny areas with rainfall of 1000-5000 mm/year. This tree is also found in secondary forests, along river banks and savannas up to an elevation of 1800 meters. Sengon is well adapted to poor, high pH or saline soils in lateritic and sandy alluvial soils.

Chinese albizia produces light wood with a density of 320-640 kg/m³ at a moisture content of 15%. The texture is a bit dense, straight fibrous and a bit rough, but easy to work with. The heartwood is glossy yellow to brown-red-ivory. Strength in class III–IV and durability in class III–IV.

Wood is used to make crates, boats, house potions and bridges. Often planted in coffee and tea plantations, parks, gardens and roadsides as shade. This tree is also planted to protect slopes and improve soil. Roots are nitrogen fixing.

Guinea grass (Panicum maximum)

Guinea grass or buffalo grass or green panic ( Panicum maximum ) is a plant species in Poaceae, annual grasses, growing upright to form clumps, strong, cultivated in all tropical and subtropical regions for very high value as fodder. P. maximum reproduces in very large pols, fibrous roots penetrate into the soil, upright stems, green, 1-1.5 m tall and have smooth cavities for diameters up to 2.5 mm. Propagation is done vegetatively and generatively. Ribbon-shaped leaves with a pointed tip, very many, built in lines, green, 40-105 cm long, 10-30 mm wide, erect, branched, a white linear bone, often covered with a layer of white wax, rough surface by hair short, dense and spread. The flower grows at the end of a long and upright stalk, open with the main axis length to more than 25 cm and the length of the bunches down to 20 cm. Grains have a size of 3x4 mm and oval. Seeds have a length of 2.25-2.50 mm and each 1 kg contains 1.2 - 1.5 million seeds. Guinea grass has two varieties. P

Redflower ragleaf (Crassocephalum crepidioides)

Sintrong or ebolo or thickhead or redflower ragleaf ( Crassocephalum crepidioides ) are plant species in Asteraceae, terma height 25-100 cm, white fibrous roots, generally grow wild on the roadside, yard gardens or abandoned lands at altitude 200- 2500 m. C. crepidioides has erect or horizontal stems along the soil surface, vascular, soft, non-woody, shallow grooves, green, rough surface and short white hair, aromatic fragrance when squeezed. Petiole is spread on stems, tubular and eared. Single leaf, spread out, green, 8-20 cm long, 3-6 cm wide, longitudinal or round inverted eggshell with a narrow base along the stalk. Pointed tip, flat-edged or curved to pinnate, jagged rough and pointed. The top leaves are smaller and often sit. Compound flowers grow throughout the year in humps that are arranged in terminal flat panicles and androgynous.

Tobacco (Nicotiana tabacum)

Tembakau or bako or tobacco ( Nicotiana tabacum ) is a plant species in Solanaceae, grows from cultivation, genetics does not change but is phenotypically dependent on soil conditions, microclimate and the local environment that causes different types of leaves. N. tabacum is a seasonal plant classified as a plantation crop. Utilization of tobacco trees, especially on leaves containing nicotine (C10H14N2) for the manufacture of cigarettes and medical materials. Plants live everywhere but grow well in the two-season region and temperatures of 20-30C. Root Tobacco trees have taproots and penetrate the soil at a depth of 50-75 cm, while small roots spread sideways and have hair to absorb water in loose soil. Stem The trunk is rather round, 5 cm in diameter and about 2.5 m high but in good conditions it can be 4 m, whereas in bad conditions it is usually only 1 m. The stem is slightly soft but strong, getting to the top the smaller. The stem is completely green and almost all
