Abstract

Ikan Koi (Cyprinus carpio) merupakan salah satu jenis ikan hias dengan nilai ekonomis tinggi yang diminati banyak orang di setiap tahunnya. Meskipun mempunyai nilai ekonomis tinggi dan juga banyak peminat, ternyata pemeliharaan ikan koi tidak mudah. Ikan koi cenderung sensitif terhadap perubahan parameter air, salah satunya adalah Total Dissolved Solid (TDS). Kandungan TDS dipengaruhi oleh bahan organik berupa feses ikan, sisa pakan, dan ion-ion pada air seperti : kalsium, fosfat, nitrat, natrium, kalium, magnesium, bikarbonat, karbonat dan klorida. Batas kadar TDS yang dapat ditoleransi oleh ikan koi adalah sebesar 500 ppm, jika kadar TDS bernilai lebih dari 500 ppm dikhawatirkan dapat mempengaruhi kesehatan dan pertumbuhan ikan koi, seperti kerusakan pada insang, menghambat laju pertumbuhan, dan menyebabkan ikan mudah terserang penyakit. Perancangan sistem pengendalian TDS dilakukan dengan cara mengukur nilai TDS pada air. Apabila nilai TDS melebihi setpoint yang telah ditentukan, maka sistem secara otomatis melakukan penggantian air. Pada sistem pengendalian ini juga dilengkapi dengan 4 sensor tambahan guna memonitoring parameter air, sensor tersebut antara lain adalah sensor Dissolved Oxygen (DO), sensor PH, sensor kekeruhan, dan juga sensor temperatur untuk memonitoring kualitas air. Proses validasi kelima sensor menghasilkan presentase error kurang dari 5% dengan akurasi lebih dari 95% yang dinilai mumpuni untuk digunakan dalam sistem kontrol yang dibuat. Sistem kontrol on/off telah berhasil menurunkan TDS air dari nilai terbesar saat pembacaan yaitu 534 ppm dan turun menjadi 369 ppm saat sistem kontrol telah selesai bekerja.

Koi fish (Cyprinus carpio) is one of the types of ornamental fish with high economic value that is highly sought after by many people every year. Despite having high economic value and a large number of enthusiasts, it turns out that Koi fish farming is not easy. Koi fish are prone to sensitivity to changes in water parameters, one of which is Total Dissolved Solids (TDS). The TDS content is influenced by organic matter such as fish waste, leftover feed, and ions in the water such as calcium, phosphate, nitrate, sodium, potassium, magnesium, bicarbonate, carbonate, and chloride. The acceptable TDS level tolerated by Koi fish is 500 ppm. If the TDS level exceeds 500 ppm, it is feared that it can affect the health and growth of Koi fish, such as damage to the gills, hindered growth rate, and susceptibility to diseases. The design of the TDS control system is done by measuring the TDS value in the water. If the TDS value exceeds the predetermined setpoint, the system automatically performs water replacement. This control system is also equipped with four additional sensors to monitor water parameters, including Dissolved Oxygen (DO) sensor, pH sensor, turbidity sensor, and temperature sensor for monitoring water quality. The validation process of these five sensors resulted in an error percentage of less than 5% with an accuracy of over 95%, which is considered competent for use in the created control system. The on/off control system has successfully reduced the water TDS from the highest recorded value of 534 ppm to 369 ppm when the control system has completed its operation.
