Study of Liquefaction Potential Using Cone Penetration Test at Balaroa Village Palu

Abstract Central Sulawesi Province is one of the areas in Indonesia that prone to large earthquakes. Balaroa, Petobo, and Sibalaya were among most fatalities damaged facilities infrastructure due earthquake on September 28th 2018. Around Balaroa Village, besides huge damages Perumnas Housing, area around housing was also affected, for example Jamur, Kelor, Labu streets, many houses buildings damaged. This research aims assess potential ground this liquefy. Cone Penetration Test (CPT) conducted at 3 points Kelor street, then results used calculate Factor Safety (FS) Liquefaction Potential Index (LPI). The indicated FS values each point sites obtained average have an value less than 1 which indicates vulnerable liquefaction. analysis liquefaction index (LPI) show a range varied from low high.
