[ABSTRACT]Pekanbaru is the capital city of Riau province, located in the center of the Sumatra Island Indonesia is experiencing rapid economic progress. The city is split by Siak river. Big bridges that connect this city are Siak I Bridge and Siak II Bridge. The Quality of Siak bridges paid attention seriously in this previous time, especially for Siak I bridge deflection, despite completely built from past time. Also for Siak II Bridge it needs more attention incase of this bridge is the road for the heavy truck way. Geological mapping using a small UAV conducted to determine the deformation points on the site of Siak I bridge and Siak II Bridge areas, the study of Siak I Bridge and Siak II Bridge are also supported by the DInSAR analysis using ALOS PALSAR data of Pekanbaru city and Deflection observation that occurs in Siak I bridge and Siak II Bridge was measured during field observation. Results of small UAV 3D models analysis shows no negative land deformation on the Siak I Bridge and Siak II Bridge areas. DInSAR analysis shows the number of positive deformation of Siak I Bridge is 81 cm and Siak II Bridge is 48 cm. Deflection on Siak I Bridge was detected around 10-15 cm.
