Abstract

Floating cages are the technology used for aquaculture activities. The dynamic factors of the sea will affect the floating cage, one factor is the waves. The waves cause a change in the position of the floating cage that affects the stability of the floating cage. The floating cage needs should have a balancing unit for stability. The model of a floating cage with a vacuum balancing unit is for a function to perform a stable position when exposed to sea waves. This research was executed by comparing models of the floating cages without a vacuum balancing unit with the floating cages installed with a vacuum balancing unit. The stability in each model is tested by comparing the two models of floating cages, exposed to the naturally wavy sea, for the changing in position was measured with the accelerometer data logger installed on each floating cage model. The sorted data of each data logger of the two models with identical sequences on the X and Y axes for comparison purposes. The results show that the value of the change in position is smaller for the floating cage installed in the vacuum balancing unit to perform more stability.
