The problem with traditional tempe production is the length of time the Tempe fermentation process takes. This happens because they still rely on the temperature and humidity of the environment, which is less than ideal. Efforts to overcome these problems with the development of electronic incubators. However, the incubator still uses a lamp that is not ideal for heating and pays less attention to the switching intensity of the actuators. This study aims to develop an incubator with temperature and humidity with a rule base control strategy. In addition, the temperature and humidity of the incubator can be monitored based on the Internet of Things (IoT). The control system design uses Arduino with temperature and humidity sensors (DHT22), while the actuators use fans, heaters, and humidifiers. The wifi connection utilizes the ESP8266 module, and the monitoring application uses the Blynk platform. A rule base is made for decision-making by simultaneously considering temperature and humidity conditions, and hysteresis techniques are accommodated to adjust the switching. The test results show that temperature control is able to reach the range of 31-35 \text{oC} while humidity control is in the range of 60-70%. The test results show that the Tempe maturity time in the incubator only takes 19 hours for the Tempe to be processed into chips. This will benefit the craftsmen because of the faster time they have the opportunity to increase production capacity. © 2022 IEEE.
