ABSTRACT: Diesel Power Plant
(PLTD) is an industry that uses diesel machines as electrical energy plant
source. The machines which in PLTD create the sound intensity that exceeds the
threshold value which can lead the workers to physiology stress. This research
aims to determine the intensity of machines sound noise and hematological
profile of PLTD operator workers differences that exposed to the sound of
Sungai Raya PLTD machine based on their working period. This research was
conducted from October to December 2015. Samples which taken as many as 25
operator workers and 6 people carriers as control. The results showed that
workers who exposed to machines sound while in the operator room of 80.84 dB
and in the engine room of 105.24 dB. The intensity of diesel machines sound in
engine room exceeds the threshold value of 85 dB that stipulated in the Decree
of the Minister of Environment No. 48 of 1996. Operator workers with working
period of 0-5 years has the number of leukocytes, LED level, the percentage of neutrophils
and monocytes higher compared to the control group and a longer working period.
In contrast, the number of erythrocytes, hemoglobin levels and lymphocyte
percentage of the operator workers 0-5 years lower than in the control group
and the other working period. The percentages of hematocrit, eosinophils and
basophils operator workers are no different to the control group and other
working periods. Workers with longer working period have a body function that
has been adapted to the working environment.
