Abstract

 Employment BPJS is a program formed by the government to provide social protection to workers. Due to the large number of workers, for example, using the Death Insurance program (JKM), it will produce abundant and accumulating data. To find out BPJS service data is to group BPJS service data in BPJS. One of the most widely used methods in the clustering method is to use the K-Means algorithm. K-Means is a non-hierarchical (block) grouping method that seeks to partition data into clusters/groups so that data with the same characteristics will be included in the clustering method. in the same cluster and data with different characteristics are grouped into another group. From the 20 data obtained 3 groups, Cluster 1 has 3 data, Cluster 2 has 4 data, and Cluster 3 has 13 data. Cluster 1 has the male sex who has the BPJS Old Age Guarantee (JHT) program which gets class III services. Cluster 2 has the male sex who has the BPJS Death Insurance (JKM) program who gets class I services. cluster 3 there are women who have the BPJS Death Guarantee program (JKM) who get class II types of services.

Abstract

The rapid growth of information technology requires a reliable data security system, especially for sensitive image files. The Advanced Encryption Standard (AES) is a symmetric algorithm that is fast and efficient; however, its main weakness lies in the vulnerability of key distribution. To address this issue, this research integrates the Lucas (LUC) algorithm to secure AES keys. LUC was chosen as it is an asymmetric algorithm utilizing public and private key pairs, ensuring the confidentiality of AES encryption keys. The purpose of this study is to design and implement an image file security system by integrating AES and LUC using Python programming language with key storage in text format. The encryption process was applied to JPG and PNG files with a maximum size of 3 MB, and the encrypted as well as decrypted results were tested through several experiments. The results indicate that the system successfully encrypted and decrypted image files while maintaining AES key confidentiality through LUC protection. The integration of these two algorithms enhances data security and can serve as a reference for the development of secure digital file systems in the future.
