Abstract - Labor pain is usually severe and only 2-4 % mothers experience light pain during labor. Labor pain is treated pharmacologically, but it comes with side effects of breathing difficulty, lower uteroplacental perfusion, fetal bradycardia, increased need for oxytocin, and it is not cheap to administer. One of the pain management methods available is heat therapy. Heat therapy is conventionally performed using warm water zack or hot water compress using a towel. However, this method comes with disadvantages of unstable temperature, wet media, and non- continuous heat effect. This paper proposes pain reduction method using automatic heat therapy with proportional integral derivative (PID) controller. It makes use of heat from an electric heater attached to metal plate. The PID controller is used to manage the required heat. A temperature sensor is attached to the plate and provides input to the PID controller. Respondents involved were delivering mothers of Stage I Active Phase Respondents were treated with 450cheat for 60 minutes. There were three groups; intermittent group treated with 15-minute treatment, 5-minute pause, and 80th minute stoppage, continuous group treated with non-stop heat that was ended on the 60th minute, and control group given simple pain management by rubbing their backs. Analytical results show an effect of p value < 0.05. Test result on the effect of pain intensity with p value 0.000 means that there is an effect of heat treatment on the reduction of pain intensity for Stage I Active Phase labor.
