Abstract :
Kedungpari village in Mojowarno sub-district has a challenging topography with many sloping areas that are prone to erosion and landslides. This plan aims to design and evaluate the performance of retaining walls using masonry as the main material. The methods used include field survey, geotechnical analysis, stability calculation and cost budget plan. The results of the field survey identified that the soil conditions at the planning site consisted mainly of sandy loam with sufficient bearing capacity for masonry construction. The retaining wall was designed using river stone masonry technique, which was chosen due to the availability of local materials, more economical cost, and good ability to drain water thus reducing hydrostatic pressure behind the wall.Stability analysis showed that the masonry retaining wall was able to withstand lateral loads and prevent soil displacement, with a factor of safety obtained of more than 1.5. The wall design also included an effective channel system to prevent water accumulation behind the wall that could cause overpressure.It is concluded that the masonry retaining wall in Kedung Pari Village not only meets the technical and safety requirements, but also provides a sustainable and economical solution. Recommendations for implementation include regular monitoring of the wall structure and channel system as well as regular maintenance to ensure the long-term effectiveness of the retaining wall.
