| Summary: | Borobudur temple has a historical value and this is one of the world cultural heritage. This temple stands on on the soil and can be deformed in the horizontal direction . Horizontal deformation monitoring is done by performing the calculation and analysis of the data size of angle and distance measurements obtained from the monitoring of network in the form of a closed traverse. It is consist of several monitoring points will be analyzed deformation, so it also analysis the quality of the design of a closed traverse that used in the study of horizontal deformation.
In practice, this study used geodetic measurements data such as distance and horizontal angle at two time observations . First measurement was made on July 5, 2011, while the second observation was made on July 13, 2012. Objects monitoring and studied were several monitoring points totaled 8 points in horizontal displacement monitoring. These points are evenly spread out in the yard and around the temple area. Data processing used the parameter least squares method. Analysis quality of web design used absolute error ellipse methode at each monitoring points, while horizontal displacement monitoring analysis used statistically and numerically through the test object point displacement.
Based on the data processing and analysis, then the results obtained from visual analysis absolute error ellipse on the monitoring points showed that measurement accuracy, the number of reference points used, and geometric shapes of network effect on the measurement of the design network quality. In addition, the horizontal deformation analysis using a statistics confidence level of 95%, obtained a result there was a horizontal displacement at point 2P3 of 8,5 mm with soutwest direction.
