Railway Vibration Level in Semarang City

Increased train traffic in the city of Semarang caused an increase vibration exposure to residents and buildings that are around railroad. Train vibrations have a large influence on comfort, human health building structures. The location this research data collection three places, namely Bulu Lor Settlement, Tawang Station area Tlogomulyo Village, reason was chosen is because route busiest so it has high level. Vibration intersection (A) velocity (v) measured when passing using level meter. results showed settlement at distance 15m from highest axle road 29.27 microns frequency 12.5 Hz lowest 4.45 63 Hz. In Area, 25m 20.38 3.55 63Hz frequency, while Kelurahan axles by 21.28 12, 5Hz 3.61 frequency. Referring research, can be concluded all values vibrational quantities still below standard according Kep-49 / MENLH 11/1996, trains do not disturb damage points location.
