P PT. Cidas Supra Metalindo was established in 1984 and becomes the leader of manufacture industry to supplying spare parts. Consider that manufacture industries have a lot of health and safety risk in every phase of production, so this research did to analyze health and safety in production process, especially in the production area of PT. Cidas Supra Metalindo. Sampling was done at 13 sampling points, those are transformer tank production and press jig, noises sampling was done when operational hours which divided by 2 shift, morning shift (08.00 -16.00), evening shift (17.00 – 00.00).Based on the calculation of equivalent noise level (Leq) and morning and afternoon noise level (Lsm) in 13 sampling points at PT. Cidas Supra Metalindo, the highest Leq in production area was 94,0 dB(A) at the 2nd point (Press jig), whereas at the 3rd point (grinding jig) was 89,6 dB(A), whereas at the 4rd point (genset) was 88,1 dB(A) and then at the 9th point was 88,7 dB(A) and at the 10th point was 87,6 dB(A). Noise level in the working area was above the noise quality standard which determine by the government (85 dB(A)). From the result of exposure time limit there are 6 points of exposure time that exceed the quality standard. At point 2 (press jig) the exposure time limit was 3,2 hours at the day time, While for point 8 (painting) equal to 6,3 hours at the day time and point 10 (machining jig) equal to 7,2 hour at the day time. This is because at that point it has noise above 90 dB (A), so the exposure time limit must be lower than that decided by OSHA Where as the lowest Leq was 55,8 dB(A) at the 13th point (field). This condition showed that PT.Cidas Supra Metalindo had transcend the noise quality standard from Kep Men Lingkungan Hidup No.48 Tahun 1996 70 dB(A). Based on the identification of the potential risk and hazard in the production area of transformer tank at PT. Cidas Supra Metalindo, the risk could happened was noise from grinding activity, hammer sound and when the worker used crane which make hearing disorders, other production activity that could make fall from the height that possible the workers to get injury and pinched in transformer tank when transport process. Based on the identification of the potential risk and hazard in the finishing area, the most risky dominant factor with the workers’ health was noise exposure. Based on the noise exposure which relate with less hearing disorder was (OR =1,333). Which is the factor that relate with the high blood pressure was noise (OR = 3,090). The related between headache and noise exposure (OR = 1,750) and then noise exposure towards fatigue (OR =2,659).
