Abstract:

Agriculture is one of the most important sectors in the Philippines because it provides food, employment, and income that contribute to national growth and development. This study aimed to evaluate the performance of a Multi-Crop prototype in terms of speed, ease of operation, and conveyor transfer efficiency, as well as the accuracy of an Arduino-powered weighing scale and the efficiency of a fan-assisted winnowing system. The researchers developed a hybrid multi-crop grain collector integrating mechanical sweeping, Arduino-based weighing with alerts, and a fan-assisted winnowing system to help farmers collect sun-dried grains more quickly and efficiently, thereby reducing post-harvest losses. Each component has a specific function: The Arduino-powered weighing scale measures grains with a maximum capacity of 20 kilograms and includes a piezoelectric buzzer that alerts the user when the weight limit is reached. The weighing scale was proven to display accurate values comparable to traditional scales, and the buzzer functioned reliably at maximum capacity. The hybrid grain collector, powered by a DC motor and human force, lifts grains into a sack and has been shown to be faster, more user-friendly, and more conveyor-efficient than manual collection. The rechargeable fan-assisted winnowing system removes light impurities mixed with the grain; however, results indicate a significant difference in the amount of chaff before and after winnowing. Overall, this study demonstrates that the hybrid Multi-Crop prototype provides a faster, easier, and more efficient method of grain collection, reducing post-harvest losses and offering labor-saving benefits for farmers and agricultural workers.
