Sweet potatoes in general, including vines that have tubers as a producer of carbohydrates, but the quantity and quality is very different from other tubers. Instant noodles are generally made from raw materials of wheat flour, but with the abundance of sweet potatoes found, noodles are made using purple sweet potato flour instead of wheat flour. The purpose of this study was to determine the effect of purple sweet potato flour substitution at various concentrations on the physical, chemical and sensory tests of instant noodles. The study was conducted at the Agroindustry Laboratory, Faculty of Agriculture, University of Tadulako, from June to December 2019. The experiment was arranged using a Completely Randomized Design (CRD) with 1 factor, namely the substitution of instant noodles purple sweet potato flour at a concentration of 0.5,10,15, 20.25 and 30%. The treatment was repeated 3 times so that 21 units of the experiment were obtained. For sensory testing using a Randomized Block Design (RBD) with a panelist of 30 people. Observation parameters consisted loss of solids due to cooking (KPAP), water absorption, water content, ash content and sensory tests. The results of the study of purple sweet potato flour substitution at various concentrations gave the best effect on the concentration of 30% on instant noodles produced based on physical, chemical and sensory properties. With the highest loss of solids due to cooking ( KPAP). The absorption of instant noodles decreases with increasing concentration of purple sweet potato flour. Instant noodle water content tends to be constant in every treatment. Ashes of instant noodles increase with increasing concentration of purple sweet potato flour and the sensory properties of color, texture, aroma, and taste of instant noodles produced increase with increasing concentration of purple sweet potato flour with hedonic scale categories like. Noodles substituted with purple sweet potato flour can be consumed as instant noodles such as those circulating in the market.
