| الوصف: | There have been many studies on natural dyes, but most have only focused on one type of plant source.This study aims to compare the color quality (Brightness and Consistency) and production costs from four sources of yello natural dyes, namely tumeric (Curcuma domestica Val), ginger rhizome (Curcuma xanthorhiza Roxb.), cosmos flowers (Cosmos sulphureus), and yellow roots (Arcangelisia Flava Merr). The method used in this study is a Completely Randomized Design with a single factor type of material. Parameters for comparision include the strenght and stability of the yellow color measured through image analysis and UV absorption spectrophotometer analysis. The treatment for the brightness test made on this research consist of 4 types of material that is: P1 = Turmeric (Curcuma domestica Val), P2 = Cosmos Flowers (Cosmos sulphureus), P3 = Yellow Root (Arcangelisia Flava Merr) and P4 = Curcuma (Curcuma xanthorhiza Roxb.). While the treatment of the color brightness consistency is 2 treatment is with acid treatment (pH 3.0-4.0) and without acid treatment with 3 times repetitions. The results showed thatthe best natural yellow dye extract is in the cosmos flower. The Cosmos flower extract has the highest color brightness level that produces the value of absorbance 0.63 and the cosmos flower extract has a higher color brightness consistency shown on the value of the 1th day that is as big as 0.63 to day 7 have value absorbance 0.52. Keywords: brightness, consistency, natural dye ABSTRAK Studi tentang pewarna alami telah banyak dilakukan, namun kebanyakan hanya fokus pada satu jenis sumber tanaman. Tidak banyak studi secara simultan yang dilakukan pada beberapa jenis bahan. Penelitian ini bertujuan membandingkan kualitas warna (kecerahan dan konsistensi) dan biaya produksi dari empat sumber pewarna alami kuning, yaitu rimpang kunyit (Curcuma domestica Val), rimpang temulawak (Curcuma xanthorhiza Roxb.),bunga cosmos (Cosmos sulphureus), dan akar kuning (Arcangelisia Flava Merr).
