<![CDATA[Swallow's nest is a material that provides great benefits, especially in relation to health and also as a profitable export/import commodity. However, it is not surprising that the swallow's nest business requires a lot of capital and swallow's nest products must be of high quality. Therefore, in swallow nest processing there are several important stages such as cleaning, shaping, drying and packing. From the above process, it is clear that the scale is a measure of water content which also affects the selling price, so a swallow hatcher is needed. The drying process greatly affects the quality of the swallow product/nest. If the swallow nest is too dry, there is a decrease in the weight of the material which can be dangerous. If it is too moist, mould will form and there may also be dirt. At this stage, drying is still done manually with the help of a fan. The fan is turned on for an hour, but sometimes the workers forget to turn off the fan, causing the swallow's nest to dry too much, which also results in a waste of electricity. The design of this dryer uses a sensor to turn on the lights and a timer to determine the time needed. With this tool can help workers in managing swallow nest dryers. The existence of this tool also helps businesses to be able to dry swallow nests automatically. Keywords: Dryer, Sensor, Timer, and Arduino]]>
