IMPLEMENTASI ALGORITMA C.45 UNTUK MENENTUKAN JURUSAN CALON SISWA SEKOLAH MENENGAH KEJURUAN (SMK)

Abstract

Every year, PPDB (New Student Acceptance) experiences the same problem where prospective students find it difficult to choose the major they will choose at SMK. Many of them took the wrong major because their parents told them to or went along without knowing their potential, so the results they obtained were relatively suboptimal and made it difficult for them to get job opportunities according to their skills. From these problems, this research was made with the aim that prospective students know what majors are relevant based on their potential. The RIASEC Personality Test which consists of Realistic, Investigative, Artistic, Social, Erterpricing, and Conventional personalities plays a role in predicting, strengthening, and convincing prospective students in choosing majors. The validity of the RIASEC test is stated to be valid and can be used but must pay attention to and match environmental conditions. This research uses calculations with Algorithm C.45. The results obtained were the classification of 4 majors namely Catering, Mechanical Engineering, Electrical Installation Engineering
