Five Key words:- formulations of effervescent tablets with different concentrations of Covid-19, Effervescent Tablet,Ginger Extract, Rosella Extract, Tablet Quality acid and base mixtures have been made to test their physical properties, both granules, and effervescent tablets. The granule physical properties test results showed that the variation of the mixture of acids and bases had no significant effect on the physical properties of the granules. The physical quality of the granule is following the applicable requirements. The same thing was also found in the weight uniformity test. In contrast, in the brittleness and hardness test, tablet formulation 5 (an acid mixture consisting only of tartaric acid) showed the best results. From the dissolution time test, it was found that the use of a mixture of citric acid and tartrate was able to accelerate TI - DEVELOPMENT OF EFFERVESCENT TABLETS BASED ON RED GINGER (ZINGIBER OFFICINALE ROSC.
