AB  - The population density and sea flooding cause the reduction in residential land and land area each
year. The way to cope with this condition is by creating a floating house. In constructing a building above
water, the shape and strength of the beam must be taken into account by considering strong materials and
structure constructions such as ferrocement. This study analyzes the structural and connection strength
between pontoon ferrocements sized 120×120×100 with 3 cm thickness and varied connection among the
pontoons. The connection variations include the connection of steel plate with a thickness of 3 cm and the
connection of round bars with a thickness of 4 cm. The modeling is constructed in the software using finite
element method and linear static analysis. The analysis of the two types of connections after given the pressure
of seawater and house load shows the stress value of steel plate connection is 107 MPa and the stress value
of round bars connection is 50 MPa. The result shows that both connections are considered safe given the fact
that based on the Rules of Indonesian Classification Bureau, the allowed stress for steel plate is 235 MPa and
for bars is 255 MPa. It means that the structures are safe. The trim pontoon condition resulted from the model
creation using Maxsurf and Hydromax Software is trim stern with the height of laden stern is 0.669 m and the
height of laden bow is 0.358 m.
