Perform a Comparison of both C4.5 and ID3 algorithms with the Cross Validation method. Itwas concluded that the problem of determining the consumer satisfaction factor of Warung Icha Steak & Seafood can be solved using data mining techniques, namely with the C4.5 and ID3 algorithms, resulting in the same decision tree and 6 rules and the most dominant factor is Service Friendliness (C8) with a gain value of 0.41370089. Testing the ID3 algorithm has a high level of accuracy of 98.50%, a Precision value of 98.77% and a Recall value of 99.38%
