The study relates to synthesis and characterization of biosensor fish freshness from dragon fruit peel extract (Hylocereus Undatus) for detecting the fish quality. This work proposes the need of detection devices that use materials from nature or known as biosensors to detect ammonia gas as a simulation to the quality detection of fish as food. The detection tool is an indicator label made of Whatman paper that has been dipped in dragon fruit peel extract (Hylocereus Undatus) used as a color in the biosensor. The extract used was made with three variations of dragon fruit peel concentration (namely 80, 100 and 120 grams) and three variations of pH (pH 2, pH 7 and pH 11). Biosensor testing was carried out for 48 hours of storage with variations in storage temperatures of 40 °C, 28 °C and 9 °C. The color changes experienced by the biosensor were analyzed using Image-J software to determine the Red Green Blue (RGB) value. A biosensor with a concentration of 100 grams of dragon fruit peel extract at pH 2 is the best biosensor for detecting the freshness of fish because it has the most optimum contrast in the color change of the biosensor. In addition, the biosensor test at the storage temperature showed that the lower the storage temperature of the fish, the more durable it would be and the slower it would decay.
