The method used in the testing of cyclamate is a deposition method while in the learning process used an experimental method (practicum). The results show that all samples tested legen containing cyclamate and exceeding the threshold is an average of the sample 1 (6 g / L), sample 2 (5.33 g / L), sample 3 (5.46 g / L), samples 4 (8.93 g / L) and sample 5 (6.26 g / L) while research using experimental method (practicum) menunjukka F count> F table (3.73> 2.66). The conclusion from this research that all traders use cyclamate exceeds the specified threshold and use of the experimental method affects the learning process on learning outcomes.
