Assessment of noise pollution exposed to workers in furniture and metal factory

Assessment of noise pollution exposed to workers in furniture and metal factory / Edy Mustaqim Muhamad
Pencemaran bunyi adalah masalah utama di seluruh dunia terutama dari kawasan industri. Kajian ini dijalankan di industri yang merupakan perabot dan kilang logam kerana baru-baru ini tidak ada kajian tentang pendedahan bunyi di industri di Malaysia. Pada masa kini, kebisingan pada kesihatan pekerja sentiasa menjadi subjek perdebatan. Kajian ini memberi tumpuan untuk menentukan punca bunyi bising di tempat kerja. Kebisingan yang dihasilkan oleh hubungan antara mesin dan permukaan kerja. Mekanisme bunyi bergantung kepada operasi dan peralatan yang bising. Kebanyakan sumber bunyi dari kajian ini adalah dari jentera dan proses produk seperti mesin pemotong, mesin penggerudian dan operasi jentera. Kajian ini menyiasat tahap bunyi bising di tempat kerja yang terdedah kepada pekerja dengan menggunakan meter tahap bunyi jenis CR1710. Tahap bunyi dari industri kebanyakannya melampaui batas dan jelas mempengaruhi pendengaran pekerja. Berdasarkan objektif kajian ini, hasil kebisingan tertinggi dalam pemerhatian adalah 91.0 dB(A) yang berada dalam zona bahaya dan melebihi batas atas pendengaran bunyi dengan 85 dB selama 8 jam kerja sehari. Kemudian, tahap hingar paling rendah adalah 54.2 dB(A) dan ia dianggap sebagai zon selamat dan di bawah keadaan kawalan bunyi. Kajian ini bertujuan untuk mendapatkan peta tahap bunyi untuk membayangkan pengedaran pencemaran bunyi, yang boleh digabungkan dengan sistem maklumat geografi dan analisis sumbangan sumber bunyi yang berbeza. _______________________________________________________________________________________________________ Noise pollution is a major problem around the world especially come from industry area. This research was conducted at the industry which is furniture and metal factory because recently no or less studies on noise exposure at Pulau Pinang industry in Malaysia. Nowadays, noise on workers’ health always a subject of debate. This study focuses on determine the source of noise at workplace. Noise produced by contact between the machine and the working surface. The mechanisms of noise depend on the noisy operation and equipment. Most of noise source from this study are from machinery and processes of product such as cutting machine, drilling machine and operation forklift. This study investigate the noise level in the workplace exposed to the workers and carried out the field work by using sound level meter type CR1710. Noise level from industry mostly exceeding the limits and obviously affects the hearing of the workers. Based on the objective of this study, the result of highest noise level in the observation is 91.0 dB(A) which is in danger zone and exceeding the upper limit for noise exposure with 85 dB for the duration 8 hours of work per day. Then, the lowest noise level is 54.2 dB(A) and it is considering as safe zone and under the control condition of noise. This study aims to obtain noise level map to visualize the distribution of noise pollution, which can be combined with geographical information system and different noise source contribution analysis.
