    Pengontrolan Oksigen Terlarut Pada Tangki Pengangkutan Ikan Menggunakan Logika Fuzzy
    (Politeknik Negeri Batam, 2017-05-15) Ariswandi; Ridwan, Ridwan; Wivanius, Nadhrah
    Controlled transport tanks for live fish are important things that are needed by the distibutor to keep the fish alive and fresh to the destination. Therefore, need a system that can control and maintain dissolved oxygen stability (Dissolved Oxygen) in water in fish transport tanks. A closed tank transport system requires pure oxygen for the survival of the fish in it. This parameter (oxygen levels) can be used as input obtained from Dissolved Oxygen sensor input to create a control system using fuzzy logic method, where fuzzy logic will compare the error and deltaerror value, so that the output oxygen can be adjusted to the requirement. The end result of this control system research shows that the transportation tank has been able to maintain the stability of dissolved oxygen in water according to the fish consumption requirement that is set with the 7.5% error rate.
