This study was aimed to investigate functional biscuit formulation based on snakehead fish flour. Research design used was complete randomized design. First step of the study was to characterize and develop snakehead fish flour, the second step was to determine functional biscuit formulation with four treatments: 0%, 10%, 15% and 20% fish flour (FF) of total weight of biscuit dough. Characterization of snakehead fish flour showed that nutrient content in 100 g was water 13.61%, ash 5.96%, protein 76.9%, fat 0.55%, carbohydrate 3.53%, Zn 3.09 mg and Fe 4.43 mg, in accordance to fish flour quality SNI 01-2715-1996/Rev. 92. Snakehead fish flour also contained albumin 24.25%. Organoleptic study in the form of hedonic test to 30 semi trained panelist showed that the highest acceptance percentage on color and odor was in 15% FF which were 96.67% and 63.33%, respectively. Highest texture acceptance was in 15% FF which was 73.33% and highest flavour acceptance was in 10% FF which was 58.33%. The acceptability of respondent showed that snakehead fish flour treatment had a significant effect (p< 0.05) on biscuit texture but it had no a significant effect (p> 0.05) on biscuit odor, flavour, color and overall. Based on subjects acceptance, biscuit formula with 15% snakehead fish flour substitution was selected.
