Abstract
Indonesia has a high geothermal energy resource, preserved in many fields. But not all geothermel fields are potential for indirect utilizations such as for electric power generation. A direct utilization of a low potential geothermal energy resource has been performed at Batukuwung geothermal field, Serang, West Java. A simple design of vegetable grain dryer has been created (constructed) using galvanis metal pipes. A reduction of temperature from 63 degrees Celcius at the heat source to 41 degrees Celcius at the dryer tool through galvanis metal pipes is quite enough for vegetable grain drying purposes. It is quite a prospect simple technology to be applied and developed in Indonesia as a geothermal energy country having various vegetable grain products from various plants such as coffee, corn, peanut and many other tropical plantations.
