Abstract

PT XYZ merupakan perusahaan yang bergerak dalam bidang industri manufaktur
otomotif yang memproduksi & distribusi sepeda motor di Indonesia. Pada salah satu proses
produksi di Seksi Machining terdapat potensi bahaya kebisingan yang disebabkan oleh
Cleaning Station yang menggunakan udara bertekanan. Pengukuran tingkat kebisingan
menggunakan sound level meter sederhana. Pada station ini kebisingan bersumber statis terjadi
secara terus-menerus pada level 95,3 dB - 101,3 dB. Hal ini tidak sesuai dengan Permenaker
RI No 5 Tahun 2018 NAB untuk paparan selama 8 jam sehari atau 40 jam seminggu adalah 85
dB. Kebisingan dapat berpotensi menyebabkan gangguan kesehatan dan keselamatan kerja
seperti gangguan komunikasi, gangguan auditory, gangguan fisiologis, dan gangguan
psikologis bagi pekerja yang terpapar. Penelitian dilakukan dengan tujuan memberi usulan
rancangan perbaikan agar tingkat kebisingan pada mesin air blow cleaning di Cleaning Station
yang diterima oleh pekerja dapat dikurangi hingga titik aman. Tahapan rancangan perbaikan
dilakukan dengan tahapan engineering controls pada metode hierarchy of controls. Untuk
mengurangi tingkat kebisingan didapatkan rancangan perbaikan dengan prototipe kotak
pengendalian bising serta pemasangan material peredam gabungan dengan komposisi plywood
(lapisan Luar), rockwool (lapisan tengah), styrofoam (lapisan dalam). Nilai penurunan tingkat
kebisingan diperoleh dengan pengujian dan pengukuran Transmission Loss (TL) hingga
Insertion Loss (IL) material uji sebelum dan sesudah dikendalikan. Reduksi total secara
keseluruhan menggunakan lapisan material gabungan, menghasilkan penurunan total daya
bunyi sebesar 32.07 dB atau 28.75% dari nilai rata-rata 111.56 dB menjadi 79.49 dB. Dengan
pengendalian tersebut didapatkan rancangan pengendalian kebisingan Cleaning Station pada
Seksi Machining.

PT XYZ is a company engaged in the automotive manufacturing industry that produces
& distributes motorcycles in Indonesia. In one of the production processes in the Machining
Section there is a potential noise hazard caused by a Cleaning Station that uses compressed air.
Measurement of noise level using a simple sound level meter. At this station, static source noise
occurs continuously at a level of 95.3 dB - 101.3 dB. This is not in accordance with Permenaker
RI No. 5 Year 2018 NAB for exposure for 8 hours a day or 40 hours a week is 85 dB. Noise
can potentially cause occupational health and safety disorders such as communication
disorders, auditory disorders, physiological disorders, and psychological disorders for exposed
workers. The research was conducted with the aim of proposing an improvement design so that
the noise level of the air blow cleaning machine at the Cleaning Station received by workers
can be reduced to a safe point. The stages of improvement design are carried out with the
engineering controls stage in the hierarchy of controls method. To reduce the noise level, an
improvement design was obtained with a noise control box prototype and the installation of a
combined damping material with the composition of plywood (outer layer), rockwool (middle
layer), styrofoam (inner layer). The noise level reduction value was obtained by testing and
measuring Transmission Loss (TL) to Insertion Loss (IL) of the test materials before and after
being controlled. The overall total reduction using the combined material layers, resulted in a
total decrease in sound power of 32.07 dB or 28.75% from the average value of 111.56 dB to
79.49 dB. With this control, a noise control design for the Cleaning Station in the Machining
Section was obtained.
