Isotonic beverages function to replace body fluids and electrolytes lost during physical activity. This study aimed to formulate an isotonic drink using local natural ingredients: liang tea as an antioxidant source, coconut water as an electrolyte source, and citrus juice as a natural source of citric acid, with xylitol as a low-calorie sweetener. The study employed a Randomized Complete Block Design (RCBD) with variations in citrus juice concentration (0, 2, 4, 6, and 8 mL), each repeated five times. Organoleptic evaluation using the hedonic method was conducted by 30 panelists who assessed color, aroma, taste, and overall preference. Data were analyzed with the Kruskal-Wallis test and effectiveness index to determine the best formulation. Results showed that the addition of citrus juice had no significant effect on color, aroma, and taste but significantly influenced overall preference. The best formulation contained 4 mL of citrus juice, with average scores of color 3.4; aroma 3.57; taste 3.47; and overall preference 3.77 (categorized as “liked”). This combination produced an isotonic beverage favored by consumers and has potential as a healthy functional drink based on local ingredients.
