<![CDATA[Sea cucumbers contain active compounds with antioxidant potential. Transparent sea cucumbers, specifically the Paracaudina australis species, can be found in Indonesia.The factors that impact the extraction outcomes include the duration of extraction, the type of solvent utilized, and the quantity of samples extracted. The objective of this research was to identify the ideal duration for extracting see-through sea cucumber in order to optimize yield parameters and antioxidant inhibitory activity.The process of extracting transparent sea cucumbers was conducted using methanol as a solvent at time intervals of 48, 72, and 96 hours. The analysis involved the examination of various parameters, including the percentage of berries, yield, phytochemical tests, and antioxidant activity using the Ferric Reducing Antioxidant Power (FRAP) method, employing a completely randomized design, which involved a variety of extraction times. The study's findings indicated that the majority of body parts that were beveled were composed of 88% stomach contents and 12% skin and flesh. Transparent sea cucumber comprises various bioactive components, including flavonoids, terpenoids, steroids, saponins, alkaloids, and phenolics, with an extraction time of 96 h, which resulted in the highest yield (7.90 %) and demonstrated the strongest antioxidant activity, with an IC50 value of 648.24 ppm. The antioxidant activity of transparent sea cucumber after various extraction times was categorized as very weak.]]>
