Abstract

Nowadays, weather conditions on Earth have become increasingly unpredictable, leading to high rainfall in certain regions. This poses a challenge for drying clothes, which typically relies on sunlight and clear weather. One potential solution is the use of a clothes dryer machine. Generally, electric dryers rely on electrical power for heat conversion, requiring between 1000 to 2000 watts, while the average residential electrical capacity ranges only from 900 to 2200 watts. Liquefied Petroleum Gas (LPG) can be used as an alternative heat source. By utilizing heat from gas combustion, the power required by the dryer can be reduced to approximately 100 to 200 watts. The clothes dryer used in this study employs an open system with LPG as the fuel source. The main components of the dryer include an igniter, solenoid valve, flame sensor, and thermostat. The research examines variations in fuel consumption rates at 0.000021 kg/s, 0.0000524 kg/s, and 0.000104 kg/s. The variables observed are drying rate, fuel consumption rate, and drying efficiency. The results show that increasing the fuel consumption rate improves the drying rate but inversely affects drying efficiency. The highest drying rate was achieved at a fuel consumption rate of 0.000104 kg/s, reaching 0.000304 kg of water per second. Meanwhile, the highest efficiency was obtained at the lowest fuel consumption rate of 0.000021 kg/s, which was 24%
