Poor, pens.ac.id – Electronic Engineering Polytechnic Institute of Surabaya (PENS) in this case the Telecommunication Engineering Study Program held community service on Friday (25/11/2022). Located in Karangsuko Village, Pagelaran District, Malang Regency. The tool applied in this community service activity is for monitoring the sound level on the mosque's loudspeakers. This tool is used to monitor the height of the loudspeaker level used in the Imamussalam Mosque.

"I checked earlier when the Friday prayer call to prayer sermon for the loudspeaker inside the mosque got a maximum result of 70 dB, and for the loudspeaker outside the mosque it got a maximum result of 80 dB - 85 dB, so according to the rules of the ministry of religion it can still be said to be safe," said Eko. one of the EEPIS lecturers involved in making this tool.
This loudspeaker level monitoring tool has been implemented and granted by lecturers and students of EEPIS Telecommunication Engineering to Karangsuko Village, Pagelaran District, Malang Regency. Through collaborative activities between the campus and the community. "Hopefully this mosque loudspeaker can help the takmir of the Immamussalam Mosque in carrying out the rules from the Ministry of Religion," said the EEPIS Lecturer who is familiarly called Pak Eko.
