Pemalang, Central Java – Yoke Mikal Ramadian, an Electrical Engineering student currently participating in the Community Service Program (KKN) in Banjarmulya Village, Pemalang District, Pemalang Regency, has successfully created a prototype innovation called BarnSense—a device designed to monitor livestock barn air quality. This innovation aims to assist local farmers in maintaining animal health through real-time air quality monitoring.

BarnSense can track various air quality parameters inside the barn, such as temperature, humidity, ammonia levels, and air circulation quality. Data collected by the sensors is processed and displayed on an application or online dashboard, allowing farmers to take immediate action when air conditions fall outside the safe range.

The development of BarnSense took place during the KKN program from July to August 2025. The device has been completed and tested in a goat barn in Banjarmulya Village. The village is known for its active livestock farming sector, making it an ideal location for the application of this simple yet valuable technology.

Air quality in livestock barns plays a crucial role in maintaining animal health. Poor air conditions, with high ammonia levels and excessive humidity, can cause respiratory diseases, reduce productivity, and even increase livestock mortality rates. With BarnSense, farmers can address such issues early and ensure the barn environment remains optimal for their animals.

The device works by using sensors to measure the surrounding air quality, displaying the results directly on a digital screen. Without requiring internet connectivity or an online platform, BarnSense is designed to be easily used by farmers in areas with limited or unstable internet access.

It is hoped that the presence of BarnSense will help farmers in Banjarmulya Village monitor livestock health more easily, reduce the risk of disease, and improve overall productivity sustainably. This innovation stands as proof that technology can provide practical solutions to challenges in rural livestock farming
