A Study among Community Living Underneath SUTET about The General Health Condition and The Electromagnetic Fields Exposures
Abstract: SUTET or the Extra
High Voltage Transmission Line of 500 kV has passed through larger residential
areas in the community. The aim of study is to provide the description of
general health condition of community residing under SUTET in the urban poor of
Jakarta and surrounding. The design of study was cross sectional, carried out
among 1200 respondents which were taken stratified proportional purposively,
based on zones of the electromagnetic field exposures. Data were collected
through observation, interview and physical examination. The electric field and
the magnetic field exposures were separately measured outside and inside the
houses. The highest electromagnetic field exposures were measured at one meter
height above the ground , for the electric field 3,1 kV/m. and the magnetic
field 550 mA/m or 687,5.10-3µT, were identified in zone 1 0-20 ms. The magnetic
field was decreasing gradually through zone 2 300mA/m and nearing zero in zone
3. Both the highest electric field and the magnetic field exposures were below
the threshold values stated by SNI 2003, 5 kV/m dan 0,1 mT or 80.104 mA/m (note:
1 A/m = 1,25 µT). The highest electric field exposure was identified at one
meter height from the ground 2,5 kV/m at 02.00–03.00 hours a.m and the highest
magnetic field 2400 mA/m at 12.00-16.00 hours p.m. The biggest portion of
houses was poor ( 30 %) were being housed for morethan 30 years. The major
diseases were found similar in all zones i.e., dental diseases, myopia and
hypertension.
