“…Distribution constant, extraction efficiency, and separation factor of Dy tend to decrease as a stirring rate more than 100 rpm. According to [12], it happens because rapid stirring rate makes the mixing of water phase and organic phase into a stable emulsion, so it is difficult to separate. Variation of nitric acid concentration.…”

Similarity of chemical and physical properties between rare-earth elements (REEs) and Dy is the main concern in order to get Dy with high purity, which it is necessary to do separation by extraction process. The purpose of this research is to obtain the optimum condition of operation (stirring time and rate, concentration of nitric acid, feed, and solvent) and determine the distribution constant, separation factor, and extraction efficiency of Dy using Aliquat 336. This research was conducted by varying stirring time (10, 15, 20, 30, 40 minutes), stirring rate (100, 150, 200, 250, 300 rpm), nitric acid concentration (2, 3, 4, 5, 6 N), feed concentration (25,000; 50,000; 100,000; 150,000; 200,000 ppm) and solvent concentration (10, 20, 30, 40, 50 % v/v). The optimum result is achieved when operation is carried out at stirring 100 rpm about 15 minutes in nitric acid 3 N with 100,000 ppm of feed concentration using 30% solvent concentration (v/v) which extract more Dy element than Yttrium (Y) and Godolinium (Gd). The highest distribution constant of Dy is 0.427, separation factor of Dy-Y is 6.831, separation factor of Dy-Gd is 1.799, and extraction efficiency of Dy is 31.604%.

“…The extraction process aims to create an equilibrium of solvent and compound concentrations in Moringa leaf cells. 11,12 The optimal solvent for the simplisia to be extracted should be used for the extraction procedure for the solvent to be maximally productive. 13 The compounds contained in Moringa have great potential as a substitute or alternative in the field of herbal medicine.…”

Introduction: The use of herbal plants in the field of dentistry has begun to be widely studied, but it is still not widely developed. One of the uses of herbal plants is to make them as raw materials for Moringauthwash. The Moringa plant (Moringa oleifera/Moringa) is an herbal ingredient that qualifies as an alternative antibacterial agent. The type of solvent, extraction temperature, and extraction duration are some variables that can affect the extraction yield, but the dominant type of solvent for the extraction of herbal plants, especially Moringa, is still not specific.This study aimed to determine the effect of solvent types on the amount of yield of the maceration of Moringa plants. Method: This was a true experimental study using a factorial complete randomized design with maceration (method of extraction) on Moringa oleifera with variations in solvent types. Results: The Kruskall-Wallis test showed that based on the solvent type treatment group, a significant value of 0.003 (<0.05) was obtained, meaning that there was an influence of the type of solvent on the amount of yield from Moringa oleifera maceration. Conclusion: In conclusion, the type of solvent has a significant effect on the amount of yield resulting from Moringa maceration.
