Analisa Klasifikasi C4.5 Terhadap Faktor Penyebab Kesulitan Siswa Dalam Menghafal Al-Quran

Abstract

To broadcast the teachings of Islam so as not to dim, one of the important things that must be done is to read and know the meaning of the Qur'an and memorize the contents of each verse of the Qur'an. Especially at SDIT Cendekia Pematangsiantar, there is a program to memorize Juz 29 and Juz 30 in Tahfidz subjects. In memorizing the Qur'an, especially at SDIT Cendekia Pematangsiantar, there are some students who have difficulty memorizing the Qur'an caused to various factors such as Tahfidz Learning (C1), the process of students memorizing the Qur'an (C2 ), student behavior at school (C3), Arabic language learning (C4), the role of parents at home (C5), and media memorizing the Qur'an (C6). This study uses a decision tree which is included in the data mining classification algorithm which aims to determine the factors that most influence students' difficulties in memorizing the Qur'an. Using the C4.5 algorithm, this algorithm makes classification simpler, and easier and also has a high level of accuracy. From the calculation with the C4.5 algorithm, the most dominant factor is the student's process of memorizing the Qur'an (C2) with a gain value of 0.498660852. The results of this study can provide information and input to teachers, school principals, and students about the causes of students' difficulties in memorizing the Qur'an.
