Abstract

          This research is aimed at creating and optimizing the solar energy drying machine, controlled by temperature, suitable for community enterprises and the knowledge of solar energy dryers. In implementation, the tools used in research are the table of trial records and the quality evaluation tables for research operations.

          Performance test result, solar energy baking, controlled by temperature, suitable for community enterprises (only sunlight), the total average of temperature at 45 °c, intensity of sunlight 497 (W/m²), and the average total drying time is 8 hours.

          Performance test result, solar energy baking, controlled by temperature, suitable for community enterprises (only bulbs), the total average of temperature at 35 °c, current 1.5 A, Voltage 220 V, and Watt 640 W, and the average total drying time is 11 hours.

          Performance test result, solar energy baking, controlled by temperature, suitable for community enterprises (only sunlight and bulb), the total average of temperature at 60 °c, current 1.5 A, Voltage 220 V, and Watt 640 W, sunlight intensity 497 (W/m²), and the average total drying time 3 hours.

          The results of the experiments can be seen as baking, energy-controlled solar dryers, with the appropriate temperature for the community enterprises. It reduces drying time.

          From the quality assessment of solar energy dryers controlled by temperature, suitable for community enterprises of 5 experts with a total average of 4.20 and standard deviation. The total average is equal to 0.55, showing that it is at a good criterion level.
