520			_aThis study focuses on the design and development of a semi-automated pelletizer machine that converts Madre de Agua, corn, and rice bran into piggery feeds. The project aims to support small and medium-scale farmers by offering a cost-efficient and labor- saving alternative to commercial pellet feeds. The machine is composed of a heat chamber, dispenser with load cell and linear actuator, grinder, and pelletizer, all managed by an Arduino Mega 2560 microcontroller. The automation system is designed to monitor temperature, weight, and motion in real time to ensure consistent pellet quality. By using natural and affordable ingredients, the machine also contributes to sustainable feed production practices. The design integrates local materials and off-the-shelf electronics to maintain low construction costs. Nutritional benefits from the selected ingredients support the dietary needs of grown and finisher pigs. The prototype was evaluated to determine whether it could operate efficiently while producing quality pellets suitable for piggery applications. Performance testing was carried out through three calibration trials to measure drying time, pellet output, moisture control, and sensor accuracy. The heat chamber consistently dried materials for an average of 20 minutes, with a steady internal mixer rotating at 40 RPM. The load cell showed accurate weight readings within a ±31-gram margin, while the servo motor rotated the dispensing bucket close to the 90° target. The moisture sensor recorded final values between 11.8% and 12.2%, which falls within the acceptable pelletizing range of 10–14%. The pelletizer operated at a stable rate of 15 kg/hour across all tests, producing uniform and well-formed pellets. The Arduino-based control system reacted precisely in a second, proving quick and dependable automation. Overall, the prototype strongly met all working goals and demonstrated consistent production. The prototype can shorten feed production time, enhance feed attribute, and economical production with proper calibration. This proposal provides a feasible and replicable finding for the local livestock Farmer looking to improve their feed manufacturing procedures. Furthermore, this thesis serves as a cornerstone for forthcoming study on enhancing automated feed production systems in small-scale agriculture.
