Pendeteksi Tingkat Kebisingan berbasis Internet of Things sebagai Media Kontrol Kenyamanan Ruangan Perpustakaan

Abstract

The library is a place that is used as a study and reading room, so that a comfortable place is needed from disturbances in the library building. Based on the decision of the Minister of Environment in 1996, the standard noise for library environments ranged from 45 to 55 dB. but in fact there is often a commotion caused by visitors. in this study a noise level detection system was created where the noise detection system is expected to be used as a media for comfort control in the library room. The noise level detector uses a sound sensor that is connected to Arduino.The system will be equipped with a warning system in the form of Buzzer and Warning Text sounds that will be displayed on the P10 LED Panel and equipped with Internet of Things technology that allows the supervisor or guard of the library to monitor the noise of the library room real time via Web Server. The test results show that this tool can detect noise levels in the range of at least 41 dB and a maximum of 69 dB with a deviation of 0.6 and an average error of 1.0%. the average sound intensity measured in the library room is 56.24 dB. The average percentage of the success of the system against Buzzer and Warning text warnings is equal to 97.3% and the average percentage of the success of sending data to the web server in the noise level detector is 95%

Wireless Data Logger Instrument for Indoor Acoustic Quality Measurement Based on Noise Background, Sound Distribution and Reverberation Time

“…According to research conducted by Nurjannah et al (2017) using the KY-037 microphone sensor, the sensor capability ranges from 31-110 dB, which is consistent with our study. Hidayat et al (2019) used a condenser microphone sensor to measure sound pressure levels in a minimum range of 41 dB and a maximum of 69 dB with an average error value of 1.0%. Although the error percentage of our instrument is larger than Hidayat et al (2019), the measurement range of ours is more comprehensive than that of Hidayat et al (2019).…”

Asni B dan Aswadul Fitri Saiful Rahman "Perancangan Sistem Kontroler Alat Elektronik Rumah Tangga Berbasis Mikrokontroler Arduino Uno Dengan Perintah Suara". Mikrokontroler Aduino Uno yang digunakan sebagai pengntrol kerja alat yang dimana alat ini menggunakan perangkat android sebagai penerima perintah suara [9].…”

Kalibrasi Aplikasi Pengukur Tingkat Suara Berbasis iOS Dengan Perangkat Pengukur Tingkat Suara Digital Di Satuan Tingkat Tekanan Bunyi dBA

“…http://ejournal.urindo.ac.id/index.php/TI Pengukuran tingkat suara kerap digunakan terkait Keselamatan Kesehatan Keamanan Kerja (K3) [8]. Adapun pengukuran tingkat suara saat ini lebih menitikberatkan pada pengukuran tingkat suara pada lingkungan maupun kawasan [2] yang memiliki standar berbeda bila dibandingan dengan K3.…”
