ANALYSIS OF THE VULNERABILITY OF EDUCATIONAL FACILITIES TO THE LEMBANG FAULT EARTHQUAKE IN THE JAMBUDIPA VILLAGE AREA, CISARUA, WEST BANDUNG

Abstract

Cisarua Subdistrict is located in an area with a high risk of earthquakes due to the presence of the active Lembang Fault, which was the cause of the earthquake that struck this area on August 28, 2011. One of the high-risk areas is Jambudipa Village, which serves as the administrative center of the subdistrict, and is home to a large number of schools. This study was conducted to examine the condition of these buildings, with a specific focus on the quality of the concrete in the primary structural elements. This is particularly important given that many of these schools have been standing for decades and were likely built before current seismic resistance standards were in place. The study employed a mixed-method approach, combining questionnaire data distributed to school principals with direct observation of the physical condition of the buildings. The Schmidt Hammer Test was carried out on columns, beams, and walls to obtain an initial estimate of concrete strength as an indicator of the structural condition of the buildings. Through this study, it is hoped that a useful preliminary picture of concrete quality in these schools can be provided, as well as a foundation for further structural evaluation and earthquake disaster risk reduction efforts in the area.
