Background: According to Riskesdas data from 2018, 59.12 percent of the Indonesian population had used herbal medicine. Product X is the result of product from Micro, Small, and Medium Enterprises (MSMEs) meeting the quality criteria of food goods, particularly herbal medicine as traditional medicine, and the maker has not specified the shelf life. The expiration date is an information that states the time limit for the use of a food or beverage product. The inclusion of shelf life is regulated in the Food Law no. 7/1996 and Government Regulation No. 69/1999 concerning Food Labels and Advertisements, where every food industry is required to include an expiration date on each food packaging. Objective: The purpose of this study was to determine the shelf life of the instant herbal medicine powder produced by Mrs. Suparni using the Accelerated Shelf Life Test (ASLT) Arrhenius Model. Method: Arrhenius model used in this experiment to determine the shelf life of instant herbal medicine powder uses the water content test parameter. Curcuma herb powder was stored for 20 days at temperatures of 25oC, 35oC, and 45oC, then observed on day 0, 5, 10, 15, and 20. Characteristics evaluation was taken on the form of organoleptic, time flow, angle of repose, and the value of mold or yeast colony. Data analysis of the results was carried out using Microsoft Excel Software. Discussion: The results showed that the shelf life determination followed zero-order reaction kinetics, when the herb powder is stored at room temperature (25oC) with a T90% value, the shelf life is 14 days. Characteristics of flow time 25 grams 2.5 seconds; angle of repose 40o; the number of molds/yeasts meets the standards of BPOM RI Regulation Number 32 of 2019. Conclusion: In the evaluation of the manufacture of the instant herbal medicine powder, the organoleptic and Yeast/Mold Number test requirements were met (Curcuma xanthorrhiza Roxb.). Temperature differences have a significant impact on how long instant ginger powder lasts (Curcuma xanthorrhiza Roxb.)
