Abstract

Toba in the past few years has declined in fish catching populations. In order to find out the fisheries of lake Toba with quickly used the acoustic methode using the de-tected backscattering strength volume of fish. The amis of this research is to determine the distribution of spatial backscattering strength of fish in the lake toba. The research was carried out in the lake toba using scientific echosounder DT-X split beam re-cording device 38-1000 KHz during six days in September. The results of the acoustic data processing showed that the highest Sv value was at depth of 50-75 m which is -32, 29 (dB) and the average is -55,82 (dB), Sv was detected on the eastern edge of lake toba waters, while the lowest Sv was detected at depth of 25-50 m which is 60.00 (dB) with the mean is -57,93 (dB) spread over the edge of the southern part of lake toba. This is influenced by the condition of the aquatic enviroment an habits of fish in the lake toba.

Abstract

Memorizing the Qur’an is a noble act that is favored by Allah SWT. Because by memorizing the Qur’an it means we are trying to maintain the purity of the Qur’an. This cannot be separated from the efforts of a teacher in guiding his students to always memorize the Qur’an from an early age. It is the teacher's hard effort that determines the success of a student in memorizing the Qur’an. This study aims to analyze the strategy of tahfizh teachers in improving students' Qur’an memorization skills. This study uses a qualitative method with a phenomenological approach. The research subjects were teachers and students. Collecting data using the method of observation, interviews and documentation. All interview results were analyzed theoretically using techniques Analysis Interactive Model Miles & Huberman, namely data collection, data reduction, data presentation and drawing conclusions. The results of the data analysis found that there were six strategies carried out by the teacher in improving students' Qur’an memorization skills, namely; i) Using various methods, such as talaqqi, tasmi’ and takriri, ii) Applying the ODOA method (one day one ayat), iii) Guiding students to routinely Muraja’ah, iv) Always motivating students to improve their memorization of the Qur’an, v) Giving rote assignments and punishments to students, vi) The teacher corrects students' reading. The results of this study can be used as initial data for future researchers to examine this issue in different contexts and issues.
