Adiel Megido, Eko Ariyanto  in this paper explain that the temperature control system on water heaters that use electric heaters, generally uses ON-OFF voltage control. Apart from this system being less efficient in using electricity, the limited range of voltage settings provided also lacks the output accuracy value required by the control system. So that for some applications it can cause a response to the temperature control system that oscillates. Another alternative in controlling the heating voltage is by using the PID control method (Proportional - Integral - Derifative), this method provides a wider range of voltage settings, so that it can provide the output accuracy value needed by the control system, thus making it possible to obtain system responses finer (minimum oscillation amplitude). In addition to problems with the temperature control system, the water volume control system in the water heater tank generally still uses probes that are installed at certain levels. The limitations in reading each change in height / volume of water causes the system output to be less linear (discrete). To produce linear readings and outputs in each change in water volume, a voltage divider can be used. In this final project design will use an electric water heater tank as a medium to determine the ability of the PID controller to control water temperature according to the set-point and control the height / volume of water in the tank using a voltage divider. Keywords : PID (Proporsional – Integral – Derifatif), Berosilasi, Set-pointReferencesMalvino, Albert Paul. 1981.

Chicken farmers in Indonesia are facing a problem as a result of the country's harsh weather conditions. Poultry species are very susceptible to temperature and humidity fluctuations. As a result, an intelligent poultry farm is necessary to intelligently adjust the temperature in the chicken coop. A smart poultry farm is a concept in which farmers may automatically manage the temperature in the chicken coop, thereby improving the livestock's quality of life. The purpose of this research is to develop a chicken coop prototype that focuses on temperature control systems on smart poultry farms via the PID control approach. The PID control method is expected to allow the temperature control system to adapt to the temperature within the cage, thereby assisting chicken farmers in their tasks. The sensor utilized is a DHT22 sensor with a calibration accuracy of 96.88 percent. The PID response was found to be satisfactory for the system with Kp = 10, Ki = 0, and KD = 0.1, and the time necessary for the system to reach the specified temperature was 121 seconds with a 1.03 % inaccuracy.

This paper studies a comparison of optimization algorithms to enhance temperature control method of thermal vacuum chamber (TVC) for satellite testing. The gaseous nitrogen (GN2) is used in TVC to control the temperature requirement and proportional integral derivative (PID) controller is adopted in order to realize it. However, the temperature profile is fluctuated and more time is needed before it managed to achieve the temperature set point. Therefore, a study is done to identify the algorithms that can be applied to optimize the temperature control system of TVC. The study is aim to improve the current temperature control in terms of settling time and overshoot.  The method used in the review is by comparing the optimization algorithms that have been used to optimize the temperature control system. The study will be done using other related works that had been done by other researchers. From the review that has been done, the genetic algorithm (GA) is believed to be the best method that can be implemented into the temperature control system of TVC.  In the future, the study will further analyse by using simulation tools and real time data generated by the TVC.
