Analisis dan Pemetaan Tingkat Kebisingan Akibat Aktivitas Produksi Industri Tapioka PT. Hari Sejahtera

Abstract

PT. Hari Sejahtera Tapioka is a prominent industry engaged in the production of tapioca flour. However, the utilization of machinery in this industry has resulted in elevated noise levels, posing a potential threat to worker safety. According to Permenaker No. 5 of 2018, the permissible noise level standard for occupational safety and health is 85 dB(A), with a maximum exposure duration of 8 hours. To assess the noise level, a comprehensive survey was administered to 100% of production department personnel. The recommended course of action involves measuring and mapping the noise level to inform initial decision-making. Noise level measurements were conducted using a Sound Level Meter (SLM), in compliance with the noise monitoring regulation stipulated in Ministry of Environment and Forestry No. 48 of 1996. This regulation mandates noise monitoring at 7 intervals during a 24-hour period, encompassing both overall and operational assessments. Based on the applicable standard, the highest recorded noise level (LSM) at PT Hari Sejahtera Tapioka was 88.86 dB(A) at point 13 on Wednesday, while the lowest noise level was 51.36 dB(A) at point 22. The research findings indicate that noise levels on working days exceed those on holidays. Moreover, the strategic deployment of barriers featuring ¾ acoustic panels on the ceiling and rockwool on the walls can effectively reduce noise levels by up to 50% in the production room.
