The University of California Irvine (UCI) Machine Learning Repository dataset that records chronic kidney disease patient data is one of the datasets that has a data loss problem. Lost data handling can be done by two methods, namely deletion and imputation. One of the deletion algorithms is ReliefF, while one of the imputation algorithms is Multiple Imputation by Chained Equation (MICE). This study aims to overcome missing data in the UCI chronic kidney disease dataset using a combination of the ReliefF and MICE algorithms. The results of the combination of algorithms were tested using the K-Nearest Neighbor (KNN) method to determine the increase in classification performance. The results of the ReliefF feature selection show that there are 15 features that influence classification with an increase in accuracy of 23,5%. The results shown from the combination of the two methods are an increase in accuracy, precision, and recall of 25,5%, 19,7%, 23,08%. The chronic kidney disease dataset experienced significant increases in accuracy, precision, and recall. It can be concluded that the combination of the ReliefF and MICE algorithms can improve classification performance in the UCI chronic kidney disease dataset.} }
