Kaledupa and Tomia islands are groups of islands incorporated in the Wakatobi Islands region. Research on the identification of tuber morphology was successfully identified consisting ten cultivars of Dioscorea alata L. and two cultivars of Dioscorea esculenta (Lour.) Burk. Each cultivar has a local name, such as D. alata cultivars from Kaledupa are called ifi tofu, ifi longko, kano ambo, ifi loiya, kano nsolo, ifi safora, ifi madu, and kano mohute; while D. alata cultivars from Tomia are named kano fungo, kano isitangisi, opa lelu, and opa honiki. The results of the chemical components analyses showed that all tubers have the potency as an alternative for food ingredient. However, the content of each component varies greatly depend on geographical conditions. Carbohydrate levels in D. alata and D. esculenta are higher than other tuber species ranging from 20.4 to 47.9%. Therefore, these ten cultivars have been used as the source of carbohydrate for a long time in the Wakatobi community.
