Teaching tahfizh al-Quran is one way to build student competence to do reasoning
in and memorizing the Al-Qur’an. Given the changes in vision and mission as stated
in the competency-based curriculum, it is necessary to make concrete efforts to
prepare and make its implementation successful. This study aims to identify the
teaching method of tahfizh al-Quran at the Tafsir Hadis Major, to explain the
strategy of optimally developing tahfizh al-Qur'an so that it can improve students'
reasoning abilities and identify the level of students' reasoning ability after
participating in the tahfizh al-Qur'an program at the Tafsir Hadis Major. This study
is a development activity carried out in collaboration between students and lecturers
to conceptually design the design of teaching materials based on experience and
existing conditions. These two stages will always be accompanied by a process of
evaluation and reflection to improve the designs developed. This research shows that
first; the sima'i method is a method that is widely used by students in memorizing
the Qur'an, secondly; the strategy of fostering tahfizh al-Quran should be done
with the muraja'ah method, Third; From the results of the calculation of the
student's reasoning ability test scores, the average score of students' reasoning
abilities in the high category was 48.82, the average category was 41.06, and the low
category has obtained an average of 39. These different average gains indicate that
the levels of students' reasoning abilities are different.
