Abstract

Penelitian ini bertujuan untuk mensimulasikan filter digital Finite Impulse Response (FIR) menggunakan metode windowing untuk menghilangkan noise pada sinyal suara. Filter FIR dipilih karena kemampuannya dalam memberikan stabilitas dan linearitas fase yang penting dalam pemrosesan sinyal digital. Beberapa metode windowing digunakan untuk merancang filter dengan karakteristik berbeda dalam hal peredaman noise dan respon frekuensi. Simulasi dilakukan menggunakan MATLAB untuk menguji efektivitas masing-masing metode windowing dalam mengurangi noise pada sinyal suara. Hasil penelitian menunjukkan bahwa Window Kaiser memberikan hasil terbaik pada noise 0,25 dBW dengan menghasilkan nilai Signal-to-Noise Ratio (SNR) sebesar 26,6632 dB. Pada level noise 0,5 dBW Window Kaiser menunjukkan performa terbaik dengan menghasilkan Signal-to-Noise Ratio (SNR) sebesar 13,4842 dB. Dilevel noise 0,75 dBW menunjukan jika metode Window Kaiser menghasilkan Signal-to-Noise Ratio (SNR) tertinggi sebesar 5,9239. Pada penelitian ini Window Rectangular mendapatkan hasil paling rendah dari ke-3 level noise. Dengan menggunakan filter FIR berbasis windowing, peningkatan kualitas audio dalam berbagai aplikasi seperti telekomunikasi dan multimedia telah terbukti. Filter FIR mampu menghilangkan noise tanpa mengorbankan komponen sinyal yang diinginkan, yang penting untuk aplikasi komunikasi yang memerlukan kejelasan audio yang tinggi.

Abstract

                This study aims to analyze the role of the excellent Al-Qur’an memorization program in shaping students’ religious and disciplined character at SMPIT Al-Madinah Boyolali. This research employed a qualitative approach with a field research design. The research subjects consisted of the principal, tahfidz teachers, and students involved in the excellent Al-Qur’an memorization program. Data were collected through observation and interviews. Data validity was tested using technique triangulation and source triangulation. The data were analyzed using the Miles and Huberman interactive model, which includes data reduction, data display, and conclusion drawing. The findings revealed that the excellent Al-Qur’an memorization program at SMPIT Al-Madinah Boyolali was implemented systematically through memorization deposit activities, muroja’ah (revision), habituation of Qur’anic reading, recitation guidance using the Al-Jauhari method, and additional activities through the Ashabbul Qur’an Club. This program contributed to shaping students’ religious character through the habituation of reading and memorizing the Qur’an, maintaining proper manners, performing worship, and fostering love for the Qur’an. In addition, the program also played an important role in shaping students’ disciplined character through habituation in following activity schedules, achieving memorization targets, regularly submitting memorization, and obeying program rules. Therefore, the excellent Al-Qur’an memorization program has a significant role in shaping the religious and disciplined character of students at SMPIT Al-Madinah Boyolali.
