Teak (Tectona grandis)

Jati or teak (Tectona grandis) is a plant species in the Lamiaceae, a large tree producing high-quality and luxurious wood, straight trunk, up to 40 m high, large leaves, slow growth with low germination making natural propagation difficult and insufficient to meet demand market.

T. grandis grows in deciduous forests that lose their leaves in the dry season, stems are cylindrical, straight, up to 40 m high, 2.4 m in diameter, 18-20 m clear bole and the bark is yellowish brown.

The leaves are ovate, opposite, very short stalks, fine hairs and glandular hairs on the underside. The leaves on the tree shoots are 60-70 cm wide, 80-100 cm long and reddish green in color. The leaves on an old tree are 15 cm wide and 20 cm long.

Compound inflorescences in large panicles, 40x40 cm, containing hundreds of flowers arranged like umbrellas, located at the tip of the twig at the top of the tree. Flowers have 6-7 corolla, whitish in color and 8 mm wide.

The fruit is round, slightly flattened, 2.5 cm, coarse hair with a thick core, 2-4 seeds but generally only one grows. The fruit is covered by enlarged flower petals that inflate like small balloons.

Teak can grow in areas with rainfall 1500-2000 mm / year, temperature 27-36C, pH 6-8, contains lots of calcium and phosphorus, is not stagnant water and lots of sunshine throughout the year, the ideal elevation is 0-700 meters.

Teak is a pioneer species that is fire-resistant and damage to the teak seed shell makes it easier for shoots to come out when the rainy season arrives. Wood has strength class II, durability class I-II and is resistant to termite attacks. The wood of the patio has a light brown to reddish brown color. The sapwood is white and yellowish gray.

Giant green leech (Raksasa hijau)

Lintah raksasa or giant green leech ( Raksasa hijau ) is a species of animal in Salifidae, large green leeches, carnivores, not hematophagic, can grow to lengths of more than 50 cm, the front is perfectly tubular, but it is getting bigger, wider and flat backward. R. hijau has a front end that ends with a white mouth and has a width equal to the diameter of the front end of the body. The rear end ends with the anus and has a width equal to the diameter of the rear end of the body. The upper surface is whole dark green or leafy green, looks shiny and has no other additional color features. The bottom surface is lighter or brownish green. The skin is wrinkled like tight, elastic joints that make it possible to lengthen the body.

Purwaceng (Pimpinella pruatjan)

Purwaceng or purwoceng or antanan gunung or Viagra of Java ( Pimpinella pruatjan or Pimpinella priatjan ) are small termas growing horizontally in Apiaceae, growing in villages on Dieng Plateau, Central Java Province, Indonesia, at 1,500 to 2,000 meters above sea level, the roots have medicinal properties for aphrodisiacs and are usually processed in powder form for a mixture of coffee or milk. P. pruatjan grows flat on the ground but does not propagate, small leaves are reddish green for 1-3 cm in diameter. This plant is only found in Java and grows in high mountain areas. A low population where industrial demand is very high results in increasingly scarce. Another place that is likely to become a purwaceng habitat is the Iyang Mountains and the Tengger Mountains in East Java Province. Efforts to multiply and cultivate have a big problem where these plants have difficulty producing seeds. In vitro propagation research through tissue cultivation has been carried out to overcome ...
