Abstract:
A review of rice husks as an energy source was carried out to provide information on their use in the drying process, especially handling post-harvest for small farmers. This is done because there are still many small farmers who only use the sun to dry their food. Drying is done by dry in the sun and this process still has drawbacks. The weakness of the process of drying in the sun is very dependent on the weather, so when it is cloudy or rainy the drying process will stop. Of course, this causes losses to small farmers, on the other hand, waste is abundant in the form of rice husks. This is related to rice as the farmer's staple crop and rice husk is a by-product of rice production. Based on several studies and libraries, a satisfactory result was obtained regarding rice husks. Rice husk can be used as sustainable alternative energy. Increasing the drying temperature, it can be done through an energy conversion process. This method is carried out by adding a heat exchanger to increase heat transfer from the burning of rice husks to the drying air. This method is also able to shorten the drying time and the dried food becomes hygienic. This is as a result of the drying process of foodstuffs carried out in the drying room, to avoid dirt and dust. Utilization of rice husks and heat exchangers as an alternative in overcoming the problems of conventional agriculture in terms of uncertain weather and climate.
