<![CDATA[This study presents the design and implementation of the Multi-Seed Smart Dryer (MSSD) control system. Other research objectives include developing a simple, low-cost, low-energy consumption dryer. The MSSD is designed to be more suitable for seed farmers. The methodology comprises engineering design, fabrication, smart-control development, and implementation. The power supply of 300 W and three (3) fans will generate hot air flow. The dry air flow moves horizontally from the left to right side through 10 rack layers in the drying chamber. Then, racks are arranged vertically to convey the seed. The smart control is designed with two modes and is based on fuzzy logic. The prototype of the dryer was tested using multiple seeds. The results show that MSSD performs well for seed drying. Functional tests using various seeds show that the drying chamber temperature ranges from 32 to 37 °C Meanwhile, relative humidity ranges from 42 to 90%. Furthermore, the germination rate of the dry seed is more than 85%. The system operated stably with an average power consumption of approximately 237 W, below the theoretical demand due to an effective control strategy, indicating energy-efficient and cost-effective drying potential for smallholder farmers under prevailing electricity tariffs (below IDR 2,000/drying cycle). Finally, MSSD can potentially be distributed to farmers for their everyday tasks in seed production.]]>
