Abstract

The inevitable dependency on rice as considered staple food in Indonesia raised concerns on various subjects such as food diversification and sufficiency. Rice analogue is artificial rice made from other carbohydrate sources than rice and wheat flour, i.e. gembili (Dioscorea esculenta). In 100 g gembili, contains 31.3 g carbohydrates, 1.1 g protein, 0.2 fat and 131 calories. Furthermore, gembili is also a potential source of inulin - a nutritional component confers a health benefit - with up to 14.62% in total, higher than the usual amount of inulin contained in other plants. BALI was made by adding sorghum flour into the mashed gembili tuber. The addition of sorghum flour provides increase in carbohydrate content of the final product, approaching to those of commercial rice. From the result obtained, in 100 g of BALI contains 43.81 g carbohydrates, 4.07 g protein, 1.13 fat and 191.3 calories. These amounts are able to provide Indonesian people daily nutrition. Based on organoleptic test that has been conducted to several respondents, the average score is between 3-4 from 5 scale in each parameter i.e. flavor, color, texture, shape, and size.
