Indonesia is rich in various types of bananas. Wild banana (Batu Bananas) is a banana type that has no economic value, because it has so many seeds. There are three varieties of batu banana in Central Java and the Special Region of Yogyakarta Indonesia, namely M. balbisiana var balbisiana (Klutuk Batu), M. balbisiana var brachycarpa (Klutuk Sukun) and M. balbisiana var. liukiuensis (Klutuk Wulung). Raw bananas are source of complex carbohydrates, including dietary fiber (DF), resistant starch (RS) and fructooligosaccharides which are very beneficial for health. The aim of this research was to identify the physical properties and evaluate the complex carbohydrate content of batu banana flesh and seeds. This research is an experimental study with a completely randomized design. The resistant starch test uses the multienzyme method (AOAC, 1995), the dietary fiber test uses the multienzyme method (AOAC, 1995), while the fructan test (FOS and inulin) uses AOAC method 999.03. The results of the analysis of resistant starch and total fiber were highest in klutuk batu seeds at 50.07% and 56.42%, consisting of 53.76% insoluble fiber and 2.66% soluble fiber. The highest fructan and FOS content was obtained from klutuk batu seeds at 6.16% and 6.11%, while the highest inulin content was found in klutuk wulung seeds at 0.51%.
