Abstract
Lateral load factor is an important parameter in the calculation of the load capacity of pile
foundation, especially in desian pile foundation in coastal areas where the impact of the
waves act as additional lateral load that significantly affect to lateral stability of pile
foundation, in this case a mini slab foundations (minipile). The interaction between the waves
with a pile foundation is a transfer force event, where the force transmitted by waves more as
a drag force than impact force. This is because the wave is a fluid material instead of solid
material. This study was conducted to determine the magnitude of the drag force due to the
waves of the sea water on cylindrical concrete slab foundations mini (minipile). The
simulation results show that the use of large diameter pile exacerbated the drag force
coefficient of drag force exerted at the same time by the sea water to the surface of minipile.
