Soga plants
Soga plants (Peltophorum pterocarpum) are a group of plants used as batik dyes whose wood
ranges from reddish-brown to black. They can be classified as legumes (Fabaceae or Leguminosae)
which spread in Asia. There are three types of soga trees that are usually used including Jambal
(Peltophorum pterocarpum), Tegeran (Cudraina javanensis), and Tingi (Ceriops Tagal). Jambal
produces a reddish-brown color from the woody trunk, and when the flowers blossom, this tree
will be lively with bunches of flowers that appear in unison; that’s why this plant is called a yellow
flame three or yellow flamboyant. Tegeran is a thorny shrub tree that is used as a maker of yellow on
fabric. This tree is spread in Java, Kalimantan, and Sulawesi, and when used as a natural coloring
agent veteran or yellow wood needs to be extracted and given fixation or reinforcing material.
Tingi is a clump of shrubs with compound leaves clustered at the ends of the branches. This plant
at a glance is similar to mangrove plants but smaller. Tingi bark is used as a producer of a dark
brownish-red in textiles (Musman and Arini (2011) in Prasetya 2018). Tingi bark used as a dye is
old bark because young tingi bark has an inferior quality with low tannin content (Jansen et al.
(2005) in Handayani, 2015).
2 METHOD
This study uses an experimental method in the form of extraction of soga bark to become a coloring
agent. The material needed is 1 kg of tall wood and 2 L of water which is then boiled for 1 hr,
and the tools necessary are pans, stoves, scales, tongs, measuring cups, used cloth, and bottles.
The extraction process begins by boiling high wood with a water solvent for 1 hour until the water
volume is reduced by half. Then cool the extract before filtering it using a used cloth. The purpose
of this filtering is to separate the extract from the dirt in the form of small pieces of wood and
powder. Finally, the extract is put into a bottle and stored in the refrigerator where the extract can
last for 14 days.
3 RESULTS & DISCUSSION
The dyeing process is carried out on a baby canvas fabric 10 cm x 10 cm in size to get color
variations from the three types of mordants used. Immersion is carried out with six time variations:
10 minutes, 20 minutes, 30 minutes, 40 minutes, 50 minutes, and 60 minutes. The results of dyeing
using soga tingi extract are shown in Table 1.
