Abstract: In Indonesia, ginger simplisia's (dried form) quality standards is regulated in SNI 01-7087-2005. The conventional drying method, direct open sun drying, has several weaknesses. It could reduce the quality of products that do not meet standards. Relating with these problems, one of the improvement efforts that can be done is by using the solar dryer technology. In this study, design and prototype of the mixed passive solar dryer has been made. Then, the solar dryer was tested to evaluate its performance. Tests were done through simulation and direct (prototype) tests. Based on the results of simulation and prototype tests, the performance of solar dryer designed was quite satisfactory (temperature ranges between 40-60°C). ANOVA and t-tests showed that there were no differences in temperature between each racks in each heat sources. In addition, based on the validation test there were no significant differences between the measurement results of the simulation and prototype tests.
