4.1. Stress simulation The Stress Simulation results with a static loading of 1.8 kg or 17.65 N that are worn on the back of the hull with balsa wood material show a maximum stress value of 1.245 N/mm 2 . This value is declared safe because it is lower than the value of the yield strength of the material that is equal to 2 N/mm 2 . The results of the Stress Simulation will be shown in Fig. 6.

4.2. Strain simulation Strain simulation conducted on the underside of the boat hull made of balsa wood to get the strain stress value given a static load value of 1.8 kg or 17.65 N, receives the maximum strain value of 3.425. The results of the Strain Simulation will be shown in Fig. 7.

4.3. Displacement simulation Static loading is also performed on displacement simulations, used to find the maximum displacement value that occurs in the boat hull. The static loading value is given at 1.8 kg or 17.65 N at the bottom of the boat hull made of balsa wood. The results of displacement simulation get a maximum value of 1.279 mm. The Displacement Simulation results will be shown in Fig. 8.

4.4. Loading variation

This loading variation is carried out on a fish feed tank with a tank capacity of ± 8 kg. A variety of loading on the tank is done in stages, starting from 2 kg, 4 kg, 6 kg and 8 kg. The results of applied loading on the tank at a capacity
