Abstract
The birth in early pregnancy and the lack of pregnancy nutrition can lead to birth problems and premature birth so that the baby easily induce hypothermia. Therefore, these babies require an incubator as a means of heating with standard temperatures between 32-37??C to help babies survive and to be able to adapt to the outside temperature. Nowadays, baby incubator on the market is using on-off control on the heating system. This condition has the disadvantage because the transient response time of the position of living long enough to off or conversely. This process certainly requires a large enough power to turn on and turn off the heater continuously. Therefore, we need a technology that is capable of controlling temperature conviniently. To overcome these problems we apply temperature control technique using Proportional-Integral-Derivative (PID). In this prototype, a designed baby incubator inside there is a two-piece box (top and bottom). Top box is used to put sensors and sensor display. While the bottom one is used to put electronic circuits, heater, and fan. The temperature sensor used is a room temperature sensor SHT11, while the temperature sensor for baby is NTC type. Baby incubator temperature changes and can be seen in the form of the temperature display on the display device. PID values are obtained by using the Ziegler-Nichols 1st method. Plant was fed by a unit-step input and the output response is obtained from the values of Kp = 13,827, Ki = 0,576, and Kd = 82,962. Each value is used into the heating system and the obtained time achievement is 4 minutes 44 seconds with set point at 32??C. Hopefully, in the future this system can be very useful for nurses and hospitals, as well as it can be redeveloped for enhancement purposes.
