Sistem Monitoring Kebisingan, Moving Average Filter (MAF), Multiple Sensor SuaraAbstract
Kampus sebagai pusat pendidikan memerlukan ruang belajar yang nyaman untuk menunjang aktivitas akademik. Perpustakaan, sebagai ruang belajar utama, harus bebas dari gangguan suara yang dapat menurunkan konsentrasi. Penelitian ini mengembangkan sistem pemantau kebisingan nirkabel dengan arsitektur multiple sound sensor dan mengimplementasikan filter digital Moving Average Filter (MAF) untuk mereduksi noise dan meningkatkan stabilitas pembacaan data. Sistem ini diuji di perpustakaan Politeknik Negeri Batam dan mampu mendeteksi tingkat kebisingan dalam rentang 38 dB hingga 100 dB. Notifikasi aktif secara otomatis saat ambang batas 55 dB terlampaui. Hasil menunjukkan bahwa MAF berhasil meredam fluktuasi sinyal dan meningkatkan akurasi sistem secara signifikan. Implementasi sistem ini berpotensi menjadi model untuk menciptakan lingkungan belajar yang optimal di ruang publik lainnya.
