Oyster mushroom can grow properly at temperatures of 16–30 °C and relative humidity of 80–95%. Environment conditioning by spraying of water in mushroom house manually in the morning and evening as the temperature and humidity controling is less effective and highly bothersome. Using of technology can controlling temperature and humidity in a mushroom house automatically.  This research aims to design an automatic control system to control temperature and humidity in oyster mushroom house. Research is located at an altitude of 125 meters above sea level. Automatic control system with a setting point temperature of 25 – 30 °C and humidity of 80 – 95% was tested at mushroom house with dimensions of 4 × 2 × 2 m with a capacity of 600 baglog mushrooms.  The results show that the performance of daily temperature and humidity without control is respectively 24.10 to 35.19 °C and 64.28 to 99.90%. While the temperature and humidity with the control system are 25.10 to 30.09 °C and 80.84 to 99.90%, respectively.

Automatic Optimization

The regulation of the coolant speed during convective drying in a stationary grain layer allows the maximum use of the amount of heat energy for drying the material. The paper presents the results of a study of the regulation of the coolant speed on an experimental drying plant for use in the automatic control system of a chamber grain dryer. The article also discusses the issues of energy saving efficiency in drying chambers. The possibility of automatic control of the main parameters control system using a microcontroller is analyzed.

Temperature And Humidity

Stress in chickens due to rising cage temperatures is a problem that is often faced by breeders, especially broiler breeders. Research with the title "temperature and humidity control system for broiler chicken coops", has formulated the research problem as follows; how to make an automatic control system to maintain the temperature and humidity of the ras broiler chicken coop to keep it stable using Arduino Uno ATMega328. In this tool it has been set, if the temperature is ≥ 30º C then the water pump will turn on, and the water pump will turn off when the temperature is ≤ 29º C. Based on the results in this study, the temperature and humidity control system succeeded in helping farmers keep the temperature of the ras broiler chicken coop remained stable, so that farmers' production can be increased. In addition, this system also helps efficiency in terms of time and labor, because this system works automatically.
