| Summary: | <p align="justify">As a country known for its agricultural commodities, crop processing is aneeded industry all across Indonesia. Crop drying is one of its common aspect. Solardryer has been developed as a way of incorporating solar energy in thermal processsuch as drying. However, the major disadvantage of every solar thermal systems isthe intermittence of solar radiation, which is heavily reliant on weather conditions.Thermal energy storage is a technology that could potentially help improvethe stability of a solar dryer. Phase change material is an attractive choice due to itshigh storing capabilities in a narrow temperature range. To evaluate the effects,simulation using ANSYS FLUENT is conducted in the condition of using PCM andwithout PCM.The simulation model is compared with experimental results from anotherstudy as a validation. The difference of PCM temperature of simulation and theexperimental results was low with the highest variation of 3,1 K. The simulationresults of air heater with PCM (paraffin and salt hydrate) and without PCM shows agreater increase in air outlet temperatur from using PCM compared to without PCMduring the period of low solar radiation. Evaluating on its daily average efficiency,each system has a value of 16, 26% 15,47%, and 13,08% in the same order.Keywords:solar dryer, air heater, thermal energy storage, PCM. <p align="justify"> <br />
