Abstract

Dalam budidaya akuaponik, kadar oksigen terlarut sangat penting karena mempengaruhi laju pertumbuhan ikan dan tanaman. Untuk menjaga kadar oksigen pada standar baku mutu air (set point), maka laju aerasi harus dimanipulasi dengan mengatur kerja pompa aerator. Langkah awal adalah dengan mengetahui karakteristik pompa aerator terhadap peningkatan kadar oksigen terlarut pada akuaponik. Selanjutnya algoritma fuzzy logic controller dibuat dan digunakan untuk menentukan variabel manipulasi dari pompa aerator pada akuaponik. Dengan menggunakan algoritma Fuzzy logic controller, kontrol kadar oksigen terlarut dapat dikontrol dan didapatkan nilai maximum overshoot (Mp) 1.27%, rise time (tr) 211 detik, settling time (ts)575 detik, ess 0.07 mg/L atau 1%. Fuzzy logic contoller mampu mengatasi gangguan dan mengikuti perubahan set point yang diberikan. Dengan kontrol kadar oksigen terlarut pada akuaponik, terjadi kenaikan laju pertumbuhan ikan sebesar 0.21 gram dan peningkatan tinggi tanaman sebesar 1.2 cm selama 10 hari pengamatan. ====================================================================================== In aquaponics, dissolved oxygen levels are important because they affect the growth rate of fish and plants that are cultivated. To maintain the dissolved oxygen level at the water quality standard (set point), the aeration rate must be manipulated by regulating work of aerator pump. The first step is to understand the aerator pump characteristic on the effect of dissolved oxygen levels on the aquaponics. Then, the fuzzy logic controller algorithm is created and used to determine the manipulation variables of aerator pumps on aquaponics. By using Fuzzy Logic Controller algorithm, the control performance of dissolved oxygen level obtained the maximum overshoot (Mp) 1.27%, rise time (tr) 211 second, settling time (ts) 574 second, ess 0.07 mg/L or 1%. The controller is able to overcome disturbance and tracking the change of set point that are given. With the controlling dissolved oxygen levels in aquaponics, result in increasing the fish growth rate by 0.21 gram or and plants height by 1.2 cm during ten days of experiment.
