Modification of Canna edulis and Maranta arundinacea starch through NaOH-Etanol was conducted to improve and expand the use of this starch in food industry, especially instant product. The objective of this study was to study the effect of the amount of NaOH on physicochemical characteristics of modified canna and maranta starches. This research used a Split Plot Design (RPB) with the main plot of type of tuber (canna and maranta) and a plot of the amount of NaOH added (0, 3, 6, 9) grams per 10 grams of starch. The observed parameter were whiteness level, yield, swelling power and solubility index, cold water-solubility, water absorption index, moisture content and ash content. The results showed that the type of tubers and the amount of NaOH significantly affected the whiteness level, cold water solubility, water absorption index, and water content. Maranta starch modified with 9 g NaOH was the best treatment with  the value of water absorption index (IAA)  is 203.95%.
