In this drying, copra produced under the specified quality standards, with the characteristics: brown, smelling of smoke, water content is quite high around 15-22% so that microorganisms are easily attacked. In this research, copra drying technology was improved by using sunlight as an energy source, in the form of a drying tuner with a roof and walls made of plastic sheeting (blue).Dryers are assembled and tried in Teluk Dalam Village, Kuala Indragiri Subdistrict, Indragiri Hilir Regency, Riau Province in October-December 2018.
