Small-leaved mahogany (Swietenia mahagoni)

Mahoni or mahogany or West Indian mahogany or small-leaved mahogany (Swietenia mahagoni) is a species of Swietenia, a medium-sized semi-evergreen tree that grows up to 35 meters long, pinnate leaves for 12-25 cm long with four to eight leaflets where each leaflet has 5-6 cm length, 2-3 cm width and do not have terminal leaflets.

S. mahagoni has small flowers and is produced in panicles. The fruit is a wooden capsule for 5-10 cm long and 3-6 cm wide and contains many winged seeds. Young trees have fine and grayish wood, but turn darker and wrinkle with age.

Small-leaved mahogany wood was famous for shipbuilding and became an important ingredient that led to the golden age of furniture making in the 18th century. Mahogany is widely used for car interiors, trains, living rooms, public buildings, hotels, residences and office supplies.

Mahogany wood is used to make modern musical instruments because of its superior tonewood quality. Sometimes used on the top of the guitar, the back, sides and neck of the mandolin. This wood is also used in making Gibson Les Paul electric guitars for Custom, Deluxe and Studio models.

A laminate of three layers of mahogany poplar and mahogany was found on the drum shell line. Some research on the acaricidal effect of leaves and bark can be used to control pests in Varroa destructor honeybees.

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 ...
