Randomized trial evaluates coastal stability and proposes mitigation strategies for vulnerable regions, indicating improved safety.

This research aims to assess coastal stability in the northern coastal zone of Java by integrating geotechnical modeling and InSAR analysis.
Conducted a geomorphological and geotechnical assessment in the Semarang–Demak corridor.
Utilized Standard Penetration Test (SPT) data and finite element modeling via PLAXIS 2D.
Analyzed subsidence rates and shoreline changes using Sentinel-1A InSAR.
Identified subsidence rates of 13.5–17.9 cm/year, surpassing natural sedimentation.
Demonstrated that untreated soft clay layers cannot sustain permanent infrastructure.
Achieved a safety factor of 1.8 in proposed mitigation strategies such as Prefabricated Vertical Drains (PVDs) and geotextile reinforcement.
