Research on the effect of case hardned slice of papaya drying using shelf-type electric oven was done by testing water content, and drying rate with temperature variable 80, 90, 100, and 110 ºC with variable thickness 1 mm , 2mm, 4mm, 6mm, and 8mm. From the research result, average water content of papaya and drying time was 84.56% with 150 minutes at 110ºC, 89.65% with 180 minutes at 100ºC, 83.17% with 225 minutes at Temperature 90 º C, and 85.57% with time 240 min at 80 ºC. The best water content of papaya which is widely evaporated is obtained at temperature 100 º C that is 89,65% and result of maximum drying rate at temperature 0,90 gram / minute
