The current SNI 1726:2012 code was developed to be the new Indonesian Seismic Design Code, SNI 1726:2019 based on the 2017 Indonesian Seismic Hazard Maps and the ASCE 7-16. It has a direct impact on the development of seismic resistance code for building design in Indonesia. The new 2019 risk targeted ground motion of spectral acceleration (S S and S 1 ), and risk coefficients, for both short (T = 0.2s) and 1-second (T = 1s) periods, respectively have been published. The paper discusses the difference of the design response spectra for building design of seven districts of Riau Province, Indonesia, according to those standard codes. The analysis was performed for three different site soil classes, that is hard (SC), medium (SD), and soft soil (SE). The design response spectra comparison of SNI 1726:2019 and SNI 1726:2012 of even districts in Riau Province, namely Bangkinang, Bengkalis, Pekanbaru, Tembilahan, Pasir Pangaraian, Dumai, Teluk Kuantan, and Siak were considered to represent the entire territory of Riau, from North to South that chosen as samplings. The purpose of this study is to evaluate the direct impact of the new code SNI 1726:2019 on design response spectra (DRS). Based on the analysis conducted at 8 cities/ districts, the improvement of DRS 2019 compared to DRS 2012 for site classes SC, SD and SE are less than 0.1g except for all site class at Tembilahan and Teluk Kuantan.
