Abstract

Klorin merupakan bahan kimia yang bersifat racun terhadap ikan. Hasil reaksi klorin jika di dalam air akan berubah menjadi asam hipoklorit yang dapat merusak sel protein dan sistem enzim pada ikan. Pada proses penetralan yang sering digunakan para pembudidaya yaitu melakukan pengendapan air semalaman untuk menguapkan klorin yang bersifat tidak stabil dan tidak efisien dalam waktu. Maka dari itu, pada tugas akhir ini dirancang bangun sistem alat penetral kadar klorin menggunakan filter karbon aktif dibantu dengan bio ring filter, busa filter biru padat, busa filter putih, dan kerikil hitam. Sensor gas electrochemical chlorine memiliki pengulangan yang sangat baik, stabilitas jangka panjang, selektivitas dan resistivitas yang berguna untuk mengontrol konsentrasi klorin pada sterilisasi air, yang mana akan diproses pada mikrokontroler Arduino Uno. Sistem ini melibatkan sebuah kontrol Proportional, Integral, Derivative (PID) dengan menggunakan pendekatan Recursive Least Squares (RLS) yang digunakan sebagai identifikasi respons sensor dan aktuator untuk membentuk model matematis data observasi secara online dari alat. Nilai paramater PID yang diperoleh yaitu P = 1,8, I = 0,05, D = -0,17, N = 0,25. Dari hasil percobaan maupun pengujian dari metode PID yang diimplementasikan pada alat, didapatkan error steady state kontrol yaitu sebesar 0,2 ppm. Hasil realisasi metode pada alat dapat dikatakan berhasil karena respons dari kontrol dapat berjalan dengan stabil mengikuti nilai setpoint. Waktu yang dibutuhkan alat dalam menetralkan 570 ml larutan kadar klorin yang dicampurkan ke dalam air akuarium yaitu 75 detik, sedangkan waktu yang dibutuhkan pada kolam ikan nila yaitu 2 jam 56 menit. ====================================================================================================== Chlorine is the kind of chemical substance which can poison fish. The water where chlorine is put will turn into Hypochlorous acid, which can destroy the fish’s protein cells and enzyme system. In fish breeding context, the water-neutralization process consists of a time-saving procedure with only one day sedimentation, the purpose being that the unstable chlorine would evaporate. Therefore, this thesis constructs an instrument to improve the overall quality of fish by means of applying the chlorine-neutralizer tools, by using active carbon filter and by the help of bio-ring filter, blue solid filter foam, white filter foam, and black gravel. The electrochemical gas sensor that will be implemented into Arduino Uno microcontroller has a good repeatability, long-term stability, selectivity and resistivity in controlling the chlorine concentration in water-sterilization procedure. This system also includes a Proportional Integral Derivative (PID) controller with Recursive Least Squares (RLS) that functions to identify the sensor’s response and as an actuator in order to form the online version of observation data of mathematical model. The parameter value of the PID acquired is P = 1,38, I = 0,05, D = -0,17, N = 0,25. Based on the trial and test using the said PID method, the error steady state control acquired is 0,2 ppm. The given method employed in the instrument is categorized as a success, because the control’s response is stable as it followed accordingly to the set point value decided beforehand. In addition, it took 74 seconds for the instrument to neutralize 570 ml of the chlorine level that was mixed altogether inside the aquarium, and 2 hours and 56 minutes for nile fish pond.
