ABSTRACT                     This study aimed to analyze the effect of lindur fruit flour substitution on organoleptic characteristics, nutritional value, and antioxidant activity of lindur fruit flour brownies. This research was conducted using a completely randomized design (CRD) with various percentages of formulation of substitution of lindur fruit flour:wheat flour, namely M1 = (100%:0%), M2 = (90%:10%), M3 = (80%:20 %), M4 = (70%:30%), and M5 = (60%:40%). The research data were analyzed using analysis of variance, with further testing using Duncan's Multiple Range Test (DMRT) at a 95% confidence level. The results show that the HCN content of lindur fruit flour reached 21.81 mg/kg. The M3 treatment was the most preferred treatment by the panelists with hedonic rating scores of color, texture, aroma, and taste reached 4.14 (like), 4.13 (like), 3.79 (like), and 4.30 (like), respectively. The nutritional values of selected M3 brownies show that it contained 30.57% water, 1.20% ash, 3.70% fat, 5.63% protein, and 58.90% carbohydrate. Analysis of antioxidant activity in selected M3 brownies was 465.58 ppm which is categorized as very weak. It can be concluded that the substitution of lindur fruit flour in making brownies had a very significant effect on color, texture, and taste. However, the effect was not significant on the aroma and the analysis of the nutritional value of the selected treatment. The brownie product substituted with lindur fruit flour met the national standards for water, ash, and fat contents.Keyword: Brownies, Lindur Fruit ABSTRAK    Penelitian ini bertujuan untuk mempelajari pengaruh substitusi tepung buah lindur terhadap karakteristik organoleptik, nilai gizi, dan aktivitas antioksidan brownies tepung buah lindur.

Sweetener is one of important factors which affect consumer acceptance as it affects the ice cream texture. Research on an alternative and healthier sweetener to substitute sugar in ice cream production has begun to emerge as consumers’ awareness on healthy food has been increasing. One of the promising alternatives was the utilization of Stevia leaf powder as it is known to have no calorie content. In this research, the best proportion of stevia leaf powder to substitute sugar in ice cream production was determined based on its physicochemical properties (viscosity, overrun, melting rate, sugar and total calories) and antioxidant activity. The research was done through laboratory experiment with a Completely Randomized Design consisted of four sugar and stevia leaf powder combinations and four replications. The treatments were P0 (20% sugar + 0% steviea leaf powder); P1 (17.5% sugar + 0.3% stevia leaf powder); P2 (16.25% sugar + 0.45% stevia leaf powder); and P3 (15% sugar + 0.6% stevia leaf powder). The obtained data was analyzed by ANOVA and further tested by Duncan’s Multiple Range Test upon significant effect.The results showed that the utilization of stevia leaf powder as sugar substitution gave highly significant effects (P<0.01) on ice cream viscosity, overrun, melting rate, sugar content, total calories and antioxidant activity. It can be concluded that the combination of 15% sugar and 0.6% stevia leaf powder (P3) produced the best ice cream characteristics with the viscosity of 1336.25 cP, overrun of 30.01%, melting rate of 37.24 minutes/50 g, sugar content of 34.63%, total calorie of 4.99 kcal and antioxidant activity of 81.92%.
