Abstract

The current high demand for rice with a consumption pattern of around 80% is not balanced by the continuous decline in national rice supply of 0.45% (140.730 tons). Thus, alternatives to rice made from cereals and tubers are needed. Maranta arundinaceae L. has the potential as an ingredient in the production of analog rice but Maranta arundinaceae L. has sticky properties, so it is necessary to have a substituent, Dioscorea esculenta which will give a hard texture to analog rice products. The research was conducted in order to obtain an analysis of how the influence of Maranta arundinaceae L. and Dioscorea esculenta in the production of analog rice on the characteristics of the nutritional of analog rice products. The production of analog rice using extrusion method with the determination of research variables using factorial design method with three independent variables which include steaming temperature, carrageenan mass, and ratio of Maranta arundinaceae L.: Dioscorea esculenta. The best analog rice characteristics are found in the analog rice formulation with a ratio of Maranta arundinaceae L. and Dioscorea esculenta of 560:240 grams at a steaming temperature of 110°C with a mass of carrageenan of 5 grams and a mass of konjac of 10 grams for 30 minutes which is determined based on water content of 8.27%, ash content of 0.33%, protein content of 6.95%, fat content of 1.6%, crude fiber content of 0.5%, and carbohydrate content of 82.58%. Based on the data obtained, this states that the nutritional content of the analog rice produced meets the requirements of the permitted rice nutritional content specifications so it can be concluded that the analog rice based on the combination of Maranta arundinaceae L.and Dioscorea esculenta produced is suitable as an alternative staple food to replace rice.
