Design of an exhaust fan with activated charcoal in a broiler closed houses for ammonia gas mitigation

Abstract

Currently, the broiler chicken coop has changed from an opened house system to a closed house system. The problem that arises with the closed house cage system is farmers only think about the health and productivity of broiler chickens in the cage, without thinking about the environmental impact caused by the ammonia gas released from the cage. It is necessary to modify the exhaust fan design with activated charcoal in closed house broilers to mitigate ammonia gas on the inside and outside of broiler chicken coop. Tools and materials used in designing the tool are Box Panel, Wireless Sensor Network, Chimney, Raspberry Pi + LCD, Activated Charcoal, MQ-5 sensor, Electric sensor & controller unit and PCB. The exhaust fans system with activated charcoal is able to absorb unpleasant odors in broiler closed houses. This tool system uses an absorbent principle that works to absorb ammonia using CaCO3 activated charcoal with an intensity of time of 14 – 16 minutes to reduce ammonia levels to 25 – 30 ppm.
