Automation design for lobster Floating Net Cage shifting from red tide in marine waters

Abstract

Floating Net Cages are a medium for lobsters rearing and at certain times, red tide caused mortality for lobsters. One solution is to shift the floating net cages in marine waters to safe waters which are controlled using a microcontroller. Water quality monitoring will be input for the microcontroller to give orders to the mooring line extension station and to command the foot station to perform tasks according to the function of each station. Field observations of the use of water quality monitoring to indicate the threat of red tide to the floating net cage location, as an order for the microcontroller to carry out; literature study includes water quality monitoring and sensor systems; the command flow in the form of a chart in the form of step by step logic from input in the form of results from monitoring water quality to avoid the threat of red tide automatically; design the hardware and create the software in the form of a command flow chart. The result of automation design is presented in the chart form which is a flow of commands from input in the form of water quality monitoring results to the process of shifting the floating net cage to avoid the threat of red tide. Information about red tide in the floating net cage environment used as input for the microcontroller commanding an automatic mooring rope length increaser and automatic floating net cage legs. Two things that used designing of the automation of shifting floating net cages for lobster rearing from red tide in marine waters: identify the presence of red tide in seawater currents leading to floating net cages for lobster rearing and action process in shifting floating net cages by two tools.
