Natural Dyes Extraction from Ulin Wood (Eusideroxylon zwageri), Secang Wood (Caesalpinia sp ) and Noni Wood (Morinda citrifolia ) for SasiranganNatural dyes have a beautiful and distinctive color that hard to imitate with synthetic colors. Natural dyes have been recommended as a dyes that safe for the environment and human health. It contains natural components that relatively low pollution load, easily biodegradable and non-toxic. The aim of this research is to identify the adsorption of natural dyes from ulin wood (Eusideroxylon zwageri), secang wood (Caesalpinia sappan) and mengkudu wood (Morinda citrifolia) to cotton and satin material by extrac and soaking processes. The results of organoleptic test showed that people prefers dyed satin than dyed cotton because the dyed colour in satin is brighter than in. The adsorption of dye in satin ranges from 1.81% to 5.68%, while in cotton ranges from 1.35% to 1.93%. The results showed that fabric with smaller size of fiber/yarn will have a higher colour adsorbtion rate because the dyes are easier to adsorb.Keywords: extraction, natural dyes, fabric, sasirangan

Ekstraksi Zat Warna dari Kulit Kayu Galam (Melaleuca leucadendron Linn) dan Evaluasi dalam Pewarnaan Kain Satin (The Extraction of Natural Dyes from Galam (Melaleuca leucadendron Linn) Bark and The Evaluation on Satin Dye Application) Nintasari, Rinne; Purwanto, Djoko

Â Â Â Â Â Galam bark has not been widely used, it was only stacked and burned. Tree bark usually contains lignocellulose and natural dye. This study aimed to evaluate the application of galam bark for natural dyes on fabric. Galam bark was extracted using soxhlet and maceration methods, with time and solvent extraction variations. The obtained natural dye was used for dyeing using lime and alum for fixation. The results showed that the soxhlet extraction with water as the solvent for 5 hours produced dye with pH value 7 (neutral) and color sharpness 21 PtCo. The soxhlet extraction with water as the solvent for 7 hours produced dye with pH 5 (acid) and the highest color sharpness 68 PtCo. The most favorable color (value 3.3) was obtained from the soxhlet extraction technique with alum fixation. The highest color adsorption value (1.95%) was obtained from the lime fixation process. The natural dye extracted from Galam bark produced color sharpness, dyes and color absorption that had not met the expected result.Keywords: galam bark, extraction, dye, fabric dyeing
