One of unique characteristics of Thai jasmine rice is its aroma, which can easily reduce in various conditions during post-harvesting activities, especially in rice milling stage. This study aims to investigate logistics cost analysis of the rice mill of Kasetwisai Agricultural Cooperative, Ltd. by using activity based costing (ABC) method and to define key activities for the improvement of the rice aroma loss reduction. The results show that the activity that has the highest logistics cost is warehousing at 26.52%, followed by material handling at 24.27%, transportation at 12.33% and packaging at 10.84% of the total logistics cost, respectively. The total logistics cost per unit of the rice mill is about 4.52 baht/kg. Findings from an in-depth interview revealed that warehousing and transportation can be major activities influencing aroma loss in jasmine rice. To reduce the aroma loss in a cost effective way, the Kasetwisai Agricultural Cooperative, Ltd. should focus on storage time and temperature in warehousing and transportation systems. In addition, the collaboration of the rice miller with supply chain partners should be encouraged to cut the logistics cost and to improve the quality of rice.
