| Abstract | Pathumthanil was the new aromatic rice of Thailand which was able to cultivate in main and second crop in irrigated area. The mismanagement of rice supply chain led to the adulteration problem and poor quality of product. This study attempted to gather the primary and secondary data of rice supply chain to analyze the optimized model for different stages of supply chain namely farming, transportation and milling processing. To find the identification method, the basic properties of three varieties (Pathum Thanil; PTT, Suphanburil; SPB1 and Suphanburi60; SPB60) was compared and chosen clearly results. Size and shape, amylose content, alkali spreading value, dye stain grain and cooking time was measured. The selected methods were verified by testing with certainly proportion of mixed rice varieties and results were compared. Finally, the RFID technology was applied for tracing back whole rice supply chain in order to provide the reliability for consumer. The results showed that there are three types of rice supply chain, which were from farm to rice mill, from farm to central market to rice mill, and from farm to broker to rice mill. The most popular chain was from farm to central market to rice mill because of highest selling price. For the farming stage, three different sizes (large, medium and small) were investigated. The operating cost per rai and yield of paddy were not significant difference (P<0.05). For transportation cost, it depended on the weight of paddy, type of vehicle, and distance. The six wheels truck and smaller size were the optimized vehicle for transportation from farm due to soft soil and improper road. To compare between three rice supply chains, the lowest cost of transportation was transported directly from farm to rice mill because it had only two stockholder. For milling model, different scale millers were compare the production cost and net revenue. The medium scale miller was appeared lower net revenue than large scale and milling cost of electrical miller was cheaper than those of milling by oil. For experiment part, the best identification method of mixed sample (PTT1:SPB1 and PTT1 and SPB60) was dye stain grain because the lowest of error percentage was observed when compared to other methods. In addition, it was rapid, economize, and without of instrumental requirement. It is suitable to be the primary checking for the adulteration at the central market. Finally, the traceability system was able to trace back to the each step of rice production by using RFID. Visual Basic 6.0 was used to interface between RFID reader and host computer including display the information in rice supply chain. Microsoft access was used to be central database; all data of farm, miller, central market and transport were saved. The tag was labeled at the truck from central market and at the final package from rice mill. This success can be the beginning step for improvement the rice supply chain in Thailand. |
