Technological developments in the health sector for the safety of neonates are essential. Such efforts are needed to curb the increase in premature infant mortality cases caused by bacteria, asphyxia, infections, and poor management of facility equipment. Furthermore, preterm and other at-risk babies have low ability to regulate temperature and produce body heat as characterized by their dry skin conditions; hence, the need for baby incubators. For their operation, these baby incubators provide strict regulated energy change that is influenced by heat transfer caused by the surrounding atmospheric temperature and humidity. This paper presents the design, construction, and performance study of a proposed Fuzzy-PID hybrid control system for regulating temperature and humidity in a baby incubator. To accomplish its goal, the proposed controller must be able to distribute heat and maintain humidity in the incubator under fluctuating atmospheric conditions to keep the baby’s body warm. Performance tests of the proposed hybrid controller were conducted by comparing temperature and humidity outputs in the baby incubator against predetermined expected values. Results show that the proposed controller is able to successfully achieve and maintain the temperature and humidity set points. Further examination also suggests that the proposed Fuzzy-PID hybrid control offers an improved overall system response performance compared to the PID controller.

The broiler is one of the chicken to be able to grow fast for producing meat in a relatively short time. In modern times broiler farms have entered the industrial scale. Poultry in this case broiler chickens breathe by inhaling oxygen and releasing carbon dioxide gas and water. In this case, if the oxygen content in the cage is too low, this condition is related to the temperature and humidity of the cage, it will affect the production and health of the chicken. This study aims to determine to find out the distribution of carbon dioxide in broiler farming in a closed house. Method, Equipment was used namely hardware and software specifications; the first, Laptop Creation of programs and real-time data retrieval is done using an Intel Core i3 - 2310M type laptop, 2 GB RAM memory and Microsoft Windows 7 operating system. The second, the Toolbox. power, driver, actuator. The three Closed House and Enclosure Support Devices measuring 1.8m x 1.3 m x 1m are made of boards, equipped with fans, lights, chickens, and sensors. The research support tools include: multimeters, cables, solder, lead, and lead suction. The fifth, MATLAB Software Th system designed is simulated with MATLAB software version 7.8.0.347 (R2009a) with Simulink facilities. The sixth is Code Vision AVR software for creating and coding programs. Code vision used is version 1.25.9. The results of monitoring system carbon dioxide test integrated in real-time the first produce 500 ppm in free air while the second test produces 1000 ppm carbon dioxide if based on the characteristics still carbon dioxide threshold in the closed house.
