Ekstraksi Dan Karakterisasi Serbuk Nano Pigmen Dari Daun Tanaman Jati (Tectona Grandis Linn. F)

Abstract

Teak plant (Tectonagrandis Linn.F) is widely used, mostly for its wood, in furniture industry. However, other parts such as leaves, are still underutilized. Teak leaves, especially the young shoots are able to produce pigment. Production of teak leaves nano pigments powder and pigment powder characterization has not been carried out. The purpose of this study was to produce nano pigment powder from young teak leaf using different filler percentage, and to characterize the pigment powder. Young teak leaf was treated with mechanical grinding and then filtered. The particle size analyzer (PSA) in solution obtained was measured with PSA. The solution was then dried with addition of 5% and 10% maltodextrin filler. The powder obtained was calculated for the yield, particle size, and solubility in water. The red color of young teak leaf filtrate derived from anthocyanin pigments contained in the young leaves of teak. Extract of young shoots have a size ranging from 87.8 nm to 318.1 nm with an average size of 109.2 nm. This suggests that the extract is a natural product in nanoscale. The addition of filler with different concentrations affected the color, yield, particle size of the powder, and the pigment solubility
