12. Role of the Indonesian Society for Geotechnical Engineering in the Development of Sustainable Earthquake-Resilience Infrastructure in the Recent Years

Indonesia has become one of the countries in the Southeast Asia region that has experienced several devastating large earthquakes, tsunami, and liquefaction induced lateral spreading for the past 15 years. Those natural disasters caused more than 140.000 casualties and damages to public infrastructure, i.e., building, roads, bridges, and housing. In order to increase the resistance against earthquake, the Government of Indonesia under the Ministry of Public Works supported by the Indonesian Society for Geotechnical Engineering (ISGE) to developed Seismic Design National Standard/Mandatory Code for Building and Non-Building, Bridge, and Dam also to established Nalodo Research Center. In line with it, continuous updates on seismic hazard source, relocated seismic catalog, seismic hazard map, ground motion collection, and research on attenuation function are conducted to identify the mechanism of seismic activities around all Indonesia, fully understand the mechanism of each source model to meet the latest state of the art on seismic hazard analysis and harmonized with the latest seismic code abroad which comply the similarity with Indonesia condition. Based on latest evaluation on Palu earthquake, a seismic hazard analysis to Jakarta and Bandung as big cities in Indonesia included basin effect and risk analysis for conventional bridges, development of technical guideline which accommodate those subjects are urgently needed to strengthening designer and practitioners that deal with design and construction of Indonesia infrastructures. Previous mistakes and uncertainties should be treated as a lesson to learn to increase knowledge and fully understand what we are dealing with. Furthermore, developing an effective solution to make Indonesia infrastructure more resilient against natural disasters and more sustainable concerning earthquakes.
