HUBUNGAN INTENSITAS KEBISINGAN DAN KARAKTERISTIK PEKERJA TERHADAP GANGGUAN DAYA DENGAR PADA PEKERJA BAGIAN PRODUKSI DI PT. METISKA FARMA KECAMATAN KEBAYORAN LAMA, JAKARTA SELATAN TAHUN 2025
Noise in the workplace is one of the primary causes of hearing loss among industrial workers, particularly those in production areas. Continuous exposure to high levels of noise exceeding the Threshold Limit Value (TLV) of 85 dBA can damage the auditory cells in the ear and lead to permanent hearing loss. Based on this issue, a study was conducted to determine the relationship between noise intensity and worker characteristics—such as age, years of service, and the use of hearing protection devices (HPDs)—with the incidence of hearing loss at PT. Metiska Farma, South Jakarta.rnThis research employed a quantitative analytic approach with a cross-sectional design and involved 33 production workers as the sample. Data collection was carried out through noise level measurements in the production area, audiometric examinations of the workers, and the distribution of questionnaires. The results showed that the average noise level reached 88 dBA, exceeding the established TLV, and 4 workers were identified with reduced hearing capacity. A significant relationship was found between noise intensity, age ≥40 years, years of service ≥10 years, and non-compliance in using HPDs with the incidence of hearing loss.rnBased on these findings, it can be concluded that noise intensity and individual worker characteristics play a role in increasing the risk of hearing impairment. Therefore, companies need to implement effective noise control programs—both technically and administratively—and enhance education and monitoring related to the consistent use of hearing protection devices to prevent further hearing damage among workers.
