PENGARUH KONSENTRASI EKSTRAK WARNA DAUN JENGKOL TERHADAP KETUAAN DAN KUALITAS HASIL PEWARNAAN EFFECT OF CONCENTRATION COLOR EXTRACT OF JENGKOL LEAVES ON THE CHAIMAN AND QUALITY OF COLORING RESULT

Abstract

Penelitian ini bertujuan untuk mengetahui: (1) pengaruh konsentrasi ekstrak warna daun jengkol terhadap
ketuaan dan kualitas hasil pewarnaan; (2) pengaruh jenis zat fiksasi terhadap ketuaan dan kualitas hasil pewarnaan.
Penelitian ini merupakan penelitian true experiment dengan teknik pengumpulan data menggunakan uji ketuaan
warna dan kualitas hasil pewarnaan ditinjau dari uji tahan luntur warna terhadap pencucian, gosokan basah, dan
sinar matahari. Analisis data menggunakan uji kruskall-wallis. Hasil penelitian menunjukkan: (1) Konsentrasi
ekstrak warna daun jengkol berpengaruh terhadap ketuaan dan kualitas hasil pewarnaan ditinjau dari ketahanan
luntur warna terhadap pencucian, gosokan basah, dan sinar matahari; (2) jenis zat fiksasi berpengaruh terhadap
ketuaan dan kualitas hasil pewarnaan yang ditunjukkan oleh tunjung menghasilkan ketuaan warna paling tua,
kualitas hasil pewarnaan menunjukkan kapur baik dalam tahan luntur warna terhadap pencucian, tawas dalam
gosokan basah, dan tunjung dalam sinar matahari.
Kata kunci: Konsentrasi, Zat Fiksasi, Ketuaan Warna, Kualitas Hasil Pewarnaan.

This study aims to determine: (1) the effect of the jengkol leaf color’s extract on frequency of dyeing and the

analysis used kruskall-wallis test. The result showed: (1) the concentration of jengkol leaf color’s extract had an
effect on the color aging test result and the quality of the coloring result in terms of the color fastness test on
washing, wet rubbing, and sunlight; (2) the type of fixation had an effect on the color aging test result and the
quality of the coloring result showed with an tunjung produces the oldest result, the quality of the staining result
showed that lime was the best in terms of the color fastness test against washing, alum was the best in terms of the
color fastness test on against wet rubbing, and the best lotus tree on the terms of the color fastness test against the
sunlight, .
