    The purpose of this study is to use water cooler and water heater to improve the convenience of the user so that they can use the water cooler and mobile water heater properly and comfortably. This study focuses on how refrigeration and water heaters use thermoelectric pads as a cooling and heating medium. Peltier works when the voltage is flowing from the power bank. The temperature difference on the surface of the processor allows the heat to occur at a fast rate. Arduino uno is used as a voltage regulator and temperature sensor to improve product performance. concept designs are designed, created and evaluated. The final prototype will include some markers that will be used as temperature readings by cooling and heating. Based on the results shown, the prototype can achieve the desired result with optimized energy consumption. When the temperature supplier produces a good temperature, the amount of water temperature will rise and the heat in the water will reach thermal equilibrium until the cold and hot temperatures reach a better minimum. Therefore, the temperatures in the cold and hot areas are more efficient in achieving thermal equilibrium in rising water.

    A study was performed to produce a pneumatic air engine using two linear actuators and then the linear motion was converted to a rotating motion using a crank shaft. This study aims to increase the use of linear actuators in pneumatic air engines as well as to apply pressurized air as an efficient and convenient transportation mechanism in line with the development of technologies developed through products available in the market. Two units of linear actuator such as pneumatic cylinders with two units of 5/2 way directional control valve with double solenoid actuation are used to control the cylinder movement. The cylinder will rotate the crank shaft when receiving a signal from the solenoid valve with 5 bar air pressure. In conclusion, the system can travel up to 153 meters for a 24-liter air-pressure with 5 bar pressure when the test is run for a charging cycle by the compressor motor. If the compressor motor able to charge the compressor continuously, the movement distance can be increased.
