EKSTRAK BIJI KESUMBA KELING (BIXA ORELLANA LINN) SEBAGAI PEWARNA ALAMI KAYU SENGON (PARASERIANTHES FALCATARIA LINN)
Abstract: Kesumba keling is a
potential plant as a natural dye can be obtained from the seeds containing
bixin is soluble in fats and norbixin is water soluble. The purpose of this
research is to find a solvent that produces the best color on staining sengon
wood and find out the leaching test in cold water and hot water on sengon wood
has been dyed from extract kesumba keling seed. The method used by Randomized
Complete Design (RCD), which consists of five comparisons solvent. The
extraction of natural dyes from kesumba keling seed using five ratio of solvent
water:ethanol (1:0), water:ethanol (1:1), water:ethanol (3:1), water:ethanol
(1:3) and water:ethanol (0:1) applied to sengon wood using heat soaking for 90
minutes. The leaching test is made by soaking the wood that has been stained in
cold water and hot water. The next is assessed by determination of color using
CIELab method. The results showed the best color sengon wood produced from wood
which is stained from extraction water:ethanol (0:1), while the smallest
fastness obtained from extracts of water:ethanol (1:0). The highest of level extact
is produced from the seeds of the extracted water:ethanol (0:1). The result of
phytochemical detect that the resulted extract containing flavonoids,
terpenoids, saponins, alkaloids and steroids.
