The cosmetics business competition in Indonesia is currently increasing so rapidly,cosmetics customers have spread to various brands, and according to taste.  The customer for the company is an asset that is very important for business continuity, so that good customer management can increase company revenue.  However, it is not easy to manage customers if they can not read the characteristics of customers, to carry out appropriate business strategies. So that requires a customer analysis method that can provide recommendations for the company.RFM  is  one  of  the  most  widely used  analytical  methods  for  analyzing  customers  throughsegmentation  and  profiling  of  customers.   In  addition  to  segmenting,  the  customer  profile is also a very important factor in analyzing customers, ALC is a form of a customer profile that can be used.  RFM + ALC method is not easy to do with very large customer history data, so data mining is needed to help conduct the RFM + ALC analysis.  Data mining methods using the clustering function with K-Means and the use of the Elbow method to get the most optimal amount of K in the clustering process can be a model used to segment with RFM, as well as the Na ̈ıve Bayes and Decision Tree classification methods to determine ALC profile factors the most influential customer.  The results of clustering modeling carried out produce two dominant customer segments.  While the Na ̈ıve Bayes classification model of the ALC factor can provide recommendations for the most influential customer profiles, with the highest level of accuracy with an accuracy value of 65.87% when compared to the Decision Tree.
