Abstract
The fabrication of solar dryers for agricultural products such as cassava and bananas has been
stadied. A tool created has two variations, namely a cover glass and a plastic cover.
Collectors used are flat plate and its constituent components other form of protective box lid
askew. Drying is carried out from 09.00 am to 13.00 pm in the interval of one hour and three
times the turnover of materials. The results show when the drying chamber is empty, the
highest temperature is 750C for tray 1 and the lowest temperature is 33.500C for tray 3. The
method is continued refueling cassava and bananas by slicing material with a thickness of 2
mm placed the above tray and dried, then it is measured at wet and dry mass from beginning
until finishing. The lowest wet mass is 144.93 g of cassava material contained in the tray 1
with water content of 4.11%, and 170.76 g banana on the tray 1 with water content of 4.38%.
The brightness index value is 31.20% to 38.96%.
