| dc.description.abstract | Indonesia's geographical location on the Pacific Ring of Fire means
that the country is often hit by natural disasters such as earthquakes.
For example, the earthquake in Yogyakarta in 2006 resulted in many
victims and damage to buildings. Therefore, this research is used to
calculate the level of building vulnerability using microtremor tools.
The method used is the Floor Spectrum Ratio (FSR) method. The
data obtained are the natural frequency value (f0), the building
resonance index value (R), and the building vulnerability index (Kb).
This research was conducted at the Applied Undergraduate
Building, Faculty of Business and Economics, Universitas Islam
Indonesia. The results obtained from this research are the average
natural frequency value of 1.11 Hz, the building resonance value of
14.34% which is categorized as high, and the building vulnerability
index of 16.14 m/s2 which is categorized as safe. Based on these
values, the FBE UII Applied Undergraduate Building is included in
the safe category. Comparative data is used to determine the
durability of building structures in the aspect of building age which
shows that both buildings were built in 2002. The secondary data in
this research is the UII Faculty of Industrial Technology Building.
The comparison obtained shows that the FTI UII Building has a
higher vulnerability value because the basement floor is categorized
as unsafe with a building vulnerability value of 127.81 m/s2
