<![CDATA[This research was conducted using local food ingredients, namely arrowroot flour substituted in potato donuts. The objectives of this study were to determine: 1) the best formula for substituting arrowroot flour in potato donuts; 2) determine the organoleptic quality characteristics of arrowroot flour substitution in potato donuts; 3) determine the best selling price of potato donut substitution. Using an experimental method with three different formulations, the ratio of wheat flour and arrowroot flour included 55%:45%, 70%:30%, and 85%:15%. Organoleptic tests were conducted by 30 panelists, consisting of 25 semi-trained panelists and 5 trained panelists, who assessed the parameters of shape, color, aroma, texture, taste, and level of preference. The test data were analyzed using a single ANOVA test and continued with a Duncan test to determine the differences between treatments. The analysis results show that: 1) the best formula 85%:15% has a value of 18.82 with the criteria of a fairly round symmetrical shape, light brown in color, quite potato-flavored, quite soft in texture, and tastes quite savory and slightly sweet; 2) produces potato donut criteria that are quite round symmetrical, brown in color, potato-flavored, soft in texture, and tastes savory and slightly sweet; 3) the selling price of the best formula is set at Rp.5600 per unit with a weight of 40 grams.]]>
