Decision Support System Model of Teacher Recruitment Using Algorithm C4.5 and Fuzzy Tahani

Abstract

During the new academic years, schools accept new students either at the level of elementary school (SD), junior high school (SMP), senior or vocational high school (SMA/SMK), as well as the existence of Islamic Education Teachers. Data taken from Local Office of Education (Diknas) of Magelang collaborated with Local Office of Religious Affairs (Kankemenag) of Magelang in 2015-2017, the Islamic Education Teachers (GPAI) recorded in 2015-2017 still less of 275 people of GPAI. It was caused by retirement, prolonged ill, and passed away. Diknas and Kemenag collaboration in openning the recruitment of GPAI is currently still using the manual system (Microsoft Excel), so it causes the administration data in that recruitment less objective and unaccountable, these are the obstacles in the teacher candidates’ recruitment which must be solved soon. How to make a system solves this problem. Meanwhile, the interest of Islamic Education Teacher (GPAI) candidates is high. To support and overcome this issue, an admission system of Islamic Education Teacher (GPAI) candidates is made so the results are accountable. Decision support system of teacher recruitment using algorithm C4.5 and Fuzzy Tahani is a system which can overcome this problem. Researchers try to build a system with the combination between the methods of Algorithm C4.5 and Fuzzy Tahani that can help the decision making in the recruitment of Islamic Education Teacher candidates. From the training results of 484 recorded criteria using attributes (1) Last Diploma; (2) University Accreditation; (3) The Faculty of Education; (4) Islamic Education (PAI) Department; (5) Police Certificate (SKCK); (6) Passport Photo; (7) ID Card; resulting in 290 recorded data of the Entropy and Gain calculation with an average time 3 minutes 15 seconds shows that percentage value of the final result those who cannot be recommended are 33%, then those who receive recommendation are 68%, with the value of entropy produced is 0.591672779.
