Kernel is a small-sized matrix with elements such as numbers. The size of the kernel on the SURF can be varied by providing variation in the value of octave and layer. Changes on this value will produce some different test parameters. Results from an optimum blend will help to optimize the process of feature detection and other processes. The detection process with the SURF feature requires a character who is able to work at its optimum. The study discusses how the characters optimum detection features to perform kernel size variations with the input of values and value octave layer. SURF or speeded up Robust Features are algorithms for feature extraction which is the development of algorithms SIFT. SURF algorithms have computation time faster than SIFT. SURF able to detect features in the form of bubbles. Detection feature with SURF consists of the process of detection and feature description. This detection process is able to form scale space with a convolution in the filter box by changing the size of the filter. The size of the filter can be changed with input variation of value and value octave layer. Testing was done by varying the rotation, scale, brightness and resolution. Standard values obtained in previous studies on the forth octave second layer. Variations of octave and layer is limited to the value of the optimum 8. Result of rotation test is at range of first until third octave, all the optimum value better than the standard value, except for the second octave, fifth and sixth layer. Result of scale test in range of first until forth octave, the optimum value of 55.5 % better than the standard value, 11.1 % similar to the standard value. Result of brightness test is at range of first until second octave, 65 % better than the optimum value of the standard value, the rest is worse than the standard value. Testing the optimum resolution in range of first until second octave. The optimum value is better at a resolution of 5 MP and above.
