Abstract

Al-Quran education is a non-formal educational institution with a type of Islamic religion aimed at providing teaching reading the Al-Quran, understanding the basic knowledge of Islam in early childhood. TPA Al-Muttaqin as a PKM-M activity partner has quite a lot of students from early childhood. The lack of teaching staff and the methods used in teaching santri were monotonous by confronting the students one by one to justify their reading, so there were only a few students when they were studying and more students played due to lack of supervision. The aim of PKM-M is to increase the understanding of santri regarding the learning of jurisprudence and iqro, to give understanding and knowledge to teachers and parents of santri by conducting counseling and socialization as well as mentoring technological knowledge in learning. The PKM-M team uses a learning by doing system method with educational-based teaching media. First, counseling activities for giving material. Second, training activities to teach coaches and instructors in implementing educational media in learning. Third, evaluation monitoring activities. So the results increase the understanding of santri regarding fiqh and iqro learning, add insight and knowledge to teachers and santri parents related to the application of educational media.

Abstract

Complete data is generally required in data analysis especially in time-series-related study. However, incomplete data due to equipment malfunction, human error, disaster, or other unknown reason is practically discovered. It is required to perform missing data prediction before forecasting the future values. Recommendation system is a system that predicts the "rating" or "preference" of a user over an item. Instead of dealing to a function of time series, the weekly precipitation data of Makassar City is placed into a matrix form consisting of "years" in row as the users and "weeks of the year" in column as the items. This method is also known as matrix decomposition. Accuracy of prediction by root mean square error (RMSE) and mean absolute error (MAE) have been performed to compare the predicted result by using the matrix decomposition to the observed values. In this study, matrix decomposition is discovered as a reliable method in dealing with the missing values of historical observation and forecasting the future values simultaneously
