WORK ENVIRONMENT FACTORS IN POLE AND LINE TYPE OF FISHING VESSELS THAT POTENTIALLY REDUCING THE HEALTH OF THE CREWS

The working environment in pole and line fishing vessels is influenced by physical factors such as vibration, noise and temperature and chemical factors in forms of dust particles and carbon monoxide (CO). The exposure of these work environment factors on the crews can affect and potentially reduce their health. The purpose of this study is to descriptively analyze the effect of work environment variables with the indicators of vibration, noise, temperature, dust particles and CO in the work environment on the health of the crew. The data collection was based on the measurements of vibration, noise, temperature, dust particles and CO on the ships that were the object of the research. In addition, the data of the health checks of the crew as respondents were also collected. The number of respondents were 127 people and the indicators of occupational health were the blood pressure, pulse and lung functions. The study was conducted on pole and line type of fishing vessels in Tulehu, Ambon Island. The result of vibration measurements on the vessels studied were 0.6 m/s2 to 4.7 m/s2. In the fishing section, the vibration level is in the range of Threshold Limit Value (TLV), which is 0.866 m/s2, however the engine room and the crew's room is not in the TLV. The noise level on the work deck is in the range of 54 dB to 83 dB and still isbelow the TLV of 85 dB. In the crew's room there are 5 ships with the noise level below the TLV with a noise level between 54 dB to 85 dB and 6 ships with the noise level above the TLV of 86 dB and 87 dB. The limit value of temperature that is safe for work environment is between 27.5?C to 32.5?C, while the temperature measurement result on the ship found that the lowest temperature of the ship is 19?C and the highest is 38?C. The lowest temperature was measured at night and the highest temperature was measured during a day. The levels of dust particles in the crew's room and engine room are still within the threshold limit value of 230 μg/m3. The CO level in the engine room with the highest value was 30,000 μg/Nm3 still fulfills the required threshold limit value of 30,000 μg/Nm3 as well as in the crew's room is below the threshold limit value. The result of the blood pressure examination on 127 respondents, it is known that 63.99% of respondents experienced a health decline, in this case suffering from hypertension blood pressure disorder. Based on the results of pulmonary function examinations on 127 respondents, it was found that 36 respondents(28.35%) had normal pulmonary function while 91 respondents (71.65%) experienced a health decline in their lung function. The health decline suffered by them are a restrictive and obstructive pulmonary function disorder.
