A hybrid drying that combines solar energy and automatic temperature control using IoT technology.

Abstract

The innovation development of  hybrid drying using automatic temperature controlled by solar energy and Internet of Things, Functional testing and innovation appropriateness were evaluated by 3 experts. Data collection was used for data analysis via Mean and Standard Deviation. The outcomes from functionality test of the innovation development, after being tested for 3 days with 3 test patterns, could be summarized as follows: 1) The empty cabinet revealed the overall average temperature of 44 degree Celsius and the overall average relative humidity of 26% ; 2) the cabinet with fermented meat inside had the overall average temperature of 47 degree Celsius and the overall average relative humidity of 15%; 3) the comparison test between the cabinet with fermented meat inside and the original method using solar energy drying revealed the overall average temperature of 47 degree Celsius and the overall average relative humidity of 20% for the developed innovation, and by using the original method of solar energy drying, the overal average temperature was 27 degree Celsius and the overall average relative humidity was 52%. The evaluation of innovation appropriateness revealed the overall highest level of Mean ( = 4.73 S.D. = 0.23). The developed innovation could help solving problems with food for insects interference and dust contamination in the air, as well as the temperature control under unusual weather, promoting wisdom community in product creation from fermented meat with hygienic preservation food, safe for consumers, and longer food storation.
