By-products from durian processing represent about 75-80% of the total weight, wheres the hust contribute that of 60-70%. This shell contains a large amount of fiber, cellulose, saponins, and starch. However, it is typically only used in developing materials with pectin adsorption or recovery properties. This study has confirmed the applicability of this byproduct in food technology. The study evaluated the appropriate ratio of durian shell powder to maintain the textural properties, quality, and consumer acceptability of biscuit products. In addition, the study also examined the correct cooking mode for supplemented cookies with durian shell powder Ri6 (Durio zllbethinus Murr.). The results showed that the biscuit product with durian shell powder increased at 20%, baked at 130°C for 12 minutes, maintained the texture properties (hardness reached 3.815 g), quality (browning index: 15.65, L* value: 55.6) and accepted by consumers.
