Abstract :
This paper presents the use of RGB color sensor to measure amount of Curcuminoids in Turmeric (Curcuma longa Linn.) and Zedoary (Curcuma Zedoarie Rose.). The measured data of fresh Turmeric sample from the color sensor in HSL (hue saturation lightness) was then compared with amount of Curcuminoids obtained by conventional method of UV-spectrophotometry. The mathematical relationship between these two kinds of data was then generated. The result of the experiment revealed that the amount of Curcuminoids increased when the Turmeric turned orangish yellow and decreased when the Turmeric turned greenish yellow. The analysis result from the color sensor implemented in this research and the conventional UV-spectrophotometry are not significantly different with high reliability 95% (p>0.05) in statistics.
