<![CDATA[The slope stability along Ir. Soekarno Hatta Road in Bontang City is vulnerable to landslides due to steep topography, requiring a durable and effective retaining structure. This study aims to design an alternative slope stabilization method using Corrugated Concrete Sheet Pile as a safe and economical solution. The research applied a numerical approach, utilizing Standard Penetration Test data, boring logs, and soil parameters modeled through Plaxis two-dimensional software to analyze the safety factor of the existing slope and after installation of Corrugated Concrete Sheet Pile. Results indicate that the existing slope has a safety factor of 1.066 under fully saturated conditions, 1.325 under partially saturated, and 1.326 under dry conditions, all below the acceptable threshold. Implementation of Corrugated Concrete Sheet Pile type W-400 increased the safety factor to 2.33, with maximum deformation of 0.79 centimeters and a maximum bending moment of 12.91 kilonewtons per meter. The findings confirm that Corrugated Concrete Sheet Pile is effective for slope reinforcement, with implications for wider application in landslide-prone areas to improve infrastructure safety and reduce long-term construction costs.]]>
