Abstract
Recently, modified cassava flour has been successfully commercialized. On the other hand, other tubers such as Canna, arrowroot, and Dioscorea sp. are still underutilized. Several researchers had developed final products including noodle, muffin, bread, keroopok, etc. Such food products require steady tuber flour supplies by which flour factory plays important roles. The study aimed at investigating the feasibility of producing tuber flour from Canna, Dioscorea sp., arrowroot, and cassava tubers either using in pack curing in a polypropylene bag plus lime stone and then ground or parboiling-fermenting fresh tuber using Rhizopus sp. and lactic acid bacteria "Bimo". Experiments were run in a nested experimental design for developing technologies at laboratory scales followed by plant design based on the laboratory data analyzed using a linear method to determining Break Event Point (BEP). Results showed that fully mechanized factory was not feasible. The flour yields reached ca 20% limited to arrowroot and cassava tubers whereas Dioscorea hispida, canna, purple Dioscorea alata, and Dioscorea esculenta L. ranged from 5.47 to 8.76%. The economic analyses showed that BEP would be feasible when the production capacity were 19,000-40,000 kg of flour per year for all tubers either using in pack curing or MoTuF technology. Therefore, the factory should processes 2:263 kg of tubers a day and its selling cost at IDR 31,514--63,000/kg is much higher compared to that of currently available flour in the market. Building a proper agro-industrial infrastructure would succeed food diversification programs. In 2012 the demands of tuber flour in East Java Province were 1,310,944.458 tons and supplies are only 691,981.748 tons/year. Bangkalan with tuber productivity of 75.986 tons is one of potential suppliers to be. In conclusion, it is recommended to establish on farm tuber factory in Bangkalan to improve supply chain for tuber products and to support diversification program.
