    Abstract

    Simplisia is a natural material dried by drying method using temperature ot more than 60 ° C, which is used for treatment and has not yet the other any process. Sun drying has many constraints such as, pale, prone to contamination from dust and others. For preventing those things, can used indirect passive solar dryer for drying simplisia. However, this solar dryer has not been tested with the real simplisia, so that performance as well as technical problem unknown yet. In addition, this solar dryer has a weakness in lacking of drying flow parameter control. This problem can be solved to use a variable inlet and exhaust. From the implementation from that mechanism it would enable for optimum setting to be achieved. For that purpose, we used experimental approach. The experiment using split split plot, where there are three factors tested, inlet choke as a plot, exhaust choke and tray position as a split. This indirect passive solar dryer testing tool uses turmeric as much as 2 kg as material test. Measured response is a reduction of turmeric water content after through drying process for 8 hours in one day. Treatment testing carried 16 times for 16 days. Data retrieval by 3 replication for each tray. Processing data using ANOVA and SNK test as a double comparison test. Further, characteristics testing drying simplisia turmeric use a tool indirect passive solar dryers. The experimental results showed that the mechanism of regulation of air flow through the inlet and exhaust holes are able providing variety the speed of drying within decrease in water levels simplisia. Setting the optimum choking ¾ of the hole inlet and exhaust holes not closed within good weather conditions. The maximum capacity of the tool can dry turmeric 6 kg for 4 days. Key words: simplisia, solar dryer, experiment, turmeric, split split plot.
