Analysis of the influence of noise and individual characteristics with non-auditory effects on workers of PT. X (Study at Lumajang factory)

Abstract

PT X is one of the factories under the auspices of one of State-Own Enterprises which manages sugar as the main commodity. This factory is one of the factories with modern sugar milling machines in the East Java area. One of the hazards of the work environment in the industry is noise. The purpose of this study was to analyze the influence between individual characteristics and non-auditory effects on employees exposed to noise in the PT X milling area. This type of research is observational with a cross sectional approach. Data collection was carried out at PT X in October 2023. The population of this study was 39 employees of the PT.X milling area. The independent variables in this study are individual characteristics (wearing ear protective equipment) and noise intensity. While the dependent variable in this study is non auditory effect complaints. Data were collected through questionnaire and measurement of noise intensity. The statistical test used was Spearman rho correlation test. The results showed that there was a correlation between APT compliance (r = 0.332) and noise intensity (r = 343) with complaints of non-auditory effects. Based on the results of the study, ear protective equipment (APT) or ear plug compliance and noise intensity have an influence on non-auditory effects. It is recommended that the company promotes the importance of using APT during the milling period in areas that have high noise intensity. In addition, there is a need for regulations regarding the use of APT to suppress the compliance of milling area employees to be more compliant with the use of APT.
