Design and Construction of a Website-Based Workplace Noise Intensity Measurement

Abstract

The Surabaya State Polytechnic of Shipping (PPNS) is implementing an Occupational Safety and Health Management System (SMK3) to create a work environment that meets industry standards. SMK3 is part of the company's overall management system, designed to control risks related to work activities and to establish a safe, efficient, and productive workplace. SMK3 includes Hazard Identification and Risk Assessment (IBPR), one of which addresses environmental noise. This research aims to design a work environment noise detection system that records noise measurement data in the PPNS construction workshop. The results will be compared with measurements taken using a sound level meter, and machine frequency values will be detected to identify noise sources. The method used to obtain decibel (dBA) values is regression calculation, while the data is transmitted from the device to the server using a Wemos D1 Mini. The outcome of this research is the development of a work environment noise detection system at PPNS, which can automatically display measurement results and provide warnings if noise levels exceed the Threshold Limit Value (NAB), which can be displayed on the website.
