CLUSTERING DATA GAJI KARYAWAN DI INDONESIA MENGGUNAKAN ALGORITMA KNN
Salary is an important aspect in the employment sector as it reflects job value and employee welfare. Along with the rapid growth of salary data availability, effective analytical methods are required to transform raw data into meaningful information. However, salary data are often complex and unlabeled, making direct analysis difficult. This study aims to group salary data using the K-Means algorithm in order to identify patterns and distribution of average salary levels. The research employs a data mining approach with a clustering technique, which belongs to unsupervised learning. Prior to clustering, the salary data undergo preprocessing, including logarithmic transformation, to improve data stability. The results indicate that the K-Means algorithm is able to classify salary data into three distinct clusters, namely low, medium, and high salary groups. The resulting clusters provide a clearer representation of salary distribution and reveal noticeable differences between salary levels. Therefore, the clustering results can serve as a foundation for salary trend analysis and support decision-making processes in the employment sector.
