| Abstract | Rice supply chain was investigated by gathering the primary and secondary data of two rice mills; one is located at the harvesting area (the Central) and the other at the marketing area (the Northeast). Models were developed based on cost minimization on farm, transportation and rice mill. Quality of paddy and milled rice were determined at different stage and the methodology on analysis such as impurity determination, measurement of moisture content, milling yield analysis, drying of high moisture paddy for price estimation. Traceability on the source of production, cultivation practice, logistic system, quality of paddy and milled rice was developed. Radio frequency identification (RFID) was implemented for the supply chain. Thai rice supply chain have various types and a lot of stakeholders throughout the country. The most common way of transportation mode was on road. The high production cost and logistic cost were the weaknesses point of rice supply chain in Thailand. The rice mill in the marketing area was high in cost of transportation and inventory. The high income from by-product was in the marketing area. Therefore, the net revenue of rice mill in the marketing area was higher than in the harvesting area. The transportation cost increased with the high moisture content of paddy which depends on volume, type of vehicle and distance of transportation. For quality analysis, optimized air velocity for impurity separation was 0.46 m/s. Electrical moisture meter with resistance type was more accuracy than the capacitance type ranging 12-18% moisture content. The best operating condition of laboratory draw dryer was at 60°C for 2 hours and gave a head rice yield about 38.5%. The best model development from 12 proposed models, it showed maximize of net revenue from farm using direct seeding cultivation, combine harvester and sun dry. The model of minimized transportation cost of farmer were 4 wheels truck, 6 wheels truck and 10 wheels truck depended on amount of paddy. For middleman, the optimized vehicle for transport paddy 50 tons was trailer and 6 wheels truck and for 100 tons was trailer truck. The optimization model on rice purchasing for rice mill showed that the high moisture and dried paddy suited for the rice mill at the harvesting and marketing area, respectively. Finally, the traceability system was able to trace source of paddy, routing and system also help miller and distributor to minimize the loss. RFID tag should be embedded on jumbo bag or container for exported rice and on plastic bag for domestic market |
