dc.description.abstractCoffee bean is one of high commodity from Indonesia. The drying process is the important step in its production. The process is to determine the moisture level of the coffee bean which also affects to the quality of a coffee. However this process takes a long time. This paper presents the optimization of the drying process of Robusta coffee bean based on Indonesian national standardization. The technology consists of hybrid solar systems as efficient resource energy and moisture level indicator using Wi-Fi data communication to efficient the operator. Test results showed that hybrid solar systems able to produce temperature 75˚C in sunny day and temperature 45˚C - 50 ˚C in mild weather. It can speed up drying processing and keep the texture of coffee bean. Besides that proposed moisture level indicator can help the operator by Wi-Fi data communication in 10 m to 100 m. It is more efficient and easy to produce coffee bean Indonesian national standardization.en_US
