Islamic boarding schools are known to be able to give birth to the Qur'an's tahfidz. With the memorization program, the halaqah about the basic text of the religion makes the Islamic boarding schools increasingly known to the community as an educational institution and a strong milestone of religious knowledge that can bring blessings. The purpose of this study was to predict the level of rote learning of the students at the Tahfiz Lan Tabur Pagaralam Islamic Boarding School. Thus, it is easier for Islamic boarding schools to take strategies to improve the quality of students themselves. The data processed in this study are data sourced from the Natural Boarding School of Tahfiz Al-Qur’an Lan Tabur Pagaralam. Based on the number of students who memorized the Al-Qur'an or Tahfidz in the 2017 to 2019 class which is processed by Monte Carlo algorithm simulation. The processing step is to bring up a random number from the sampling data that has been taken. The results of testing on this method found that the system used to predict the level of memorization of the Al-Qur'an with an average accuracy of 84% in 2018 and an average accuracy of 88% in 2019. With a high degree of accuracy, simulations performed using the Monte Carlo algorithm can predict the number of students memorized by the Qur'an, making it easier for Islamic boarding schools to obtain information about the likelihood of future events at the level of memorization of students at Islamic boarding schools Alam Tahfiz Al-Qur’an Lan Tabur Pagaralam.

Adolescence is a period of transition. There are so many problems that arise in adolescence, so they need special attention. Adolescence is a period of searching for identity, so many teenagers sometimes fall into juvenile delinquency. There are many factors that cause juvenile delinquency, and if not handled properly can cause decreased academic achievement. One factor that can handle it is religiosity. This research observed the student class XI of Senior High School X. The purpose of this observation is to see the correlation between religiosity and student’s achievement class XI at Senior High School X. As hypothesis, there is positive correlation between religiosities and student’s achievement. It shows when the religiosities are high, so the student’s achievement will be high. In the other hand when the religiosities are low, so the student’s achievement will be low. The population in this research are all student in ninth class (XI) at Senior High School X  it totally 77 students. And the sampling technique that used is saturated sample.The sample taking is appropriate with Sugiyono opinion (2013), when the subject of the research relative small, so it better to take all subject. So the research called population research. It is done because the number of population relative small and the researcher want make the generalization with very small mistake. All students at ninth class totally 77 students, so the samples in this research are 77 students. The measuring instrument that used is religiosities scale that arranged based on the theory and the documentation of student report to see study achievement. The data analyzing method that used for hypothesis testing in this research is using product moment correlation Pearson that shows (r) = 0,589 with score (p) = 0,000 (p<0,01), Means the there is significant correlation with positive   between religiosities with student achievement. In conclusion the hypothesis of this research can be accepted.
