Abstract

Sistem budidaya ikan nila membutuhkan pengelolaan kualitas air dan pemberian pakan yang optimal untuk mendukung pertumbuhan ikan yang sehat. Sistem RAS (Recirculating Aquaculture System) merupakan gabungan dari sistem filtrasi dimana sistem sirkulasi air kolam dengan menambahkan filter serta sistem aerasi yang mana menambahkan suplai oksigen ke dalam air kolam sehingga kualitas air tetap terjaga dan optimal. Namun, perlu dilakukan monitoring terhadap kualitas air, seperti pH, kekeruhan, serta temperatur air kolam agar kualitas air tetap optimal untuk budidaya. Berdasarkan permasalahan tersebut maka dirancang sistem Recirculating Aquaculture System (RAS) yang dilengkapi dengan monitoring kualitas air secara otomatis. Sistem monitoring kualitas air menggunakan sensor SEN0189 untuk mendeteksi kadar kekeruhan, sensor PH-4502C untuk mengukur tingkat keasaman (pH), serta sensor DS18B20 untuk memantau temperatur air. Hasil dari sistem monitoring mendapatkan nilai akurasi 99.69% pada sensor PH-4502C, 95.85% pada sensor temperatur DS18B20, serta 93.58% pada sensor kekeruhan SEN0189. Hasil dari akurasi sensor kekeruhan kurang baik dikarenakan nilai pembacaan yang fluktuatif serta nilai persentase error melebihi 5%. Hasil akurasi sensor pH dan temperatur memiliki nilai persentase error kurang dari 5%. Filtrasi pada sistem RAS dapat bekerja dengan baik dibuktikan dengan hasil monitoring selama 8 hari serta kelangsungan hidup ikan nila.

Tilapia farming systems require optimal water quality management and feeding to support healthy fish growth. The RAS (Recirculating Aquaculture System) is a combination of filtration systems where the pond water circulation system is enhanced with filters and an aeration system that supplies oxygen to the pond water, ensuring water quality remains maintained and optimal. However, monitoring of water quality, such as pH, turbidity, and pond water temperature, is necessary to maintain optimal water quality for aquaculture. Based on these issues, a Recirculating Aquaculture System (RAS) equipped with automatic water quality monitoring was designed. The water quality monitoring system uses the SEN0189 sensor to detect turbidity levels, the PH-4502C sensor to measure acidity (pH), and the DS18B20 sensor to monitor water temperature. The monitoring system achieved an accuracy rate of 99.69% for the PH-4502C sensor, 95.85% for the DS18B20 temperature sensor, and 93.58% for the SEN0189 turbidity sensor. The turbidity sensor's accuracy was lower due to fluctuating readings and an error percentage exceeding 5%. The accuracy of the pH and temperature sensors had error percentages below 5%. Filtration in the RAS system functioned effectively, as evidenced by the monitoring results over 8 days and the survival rate of the tilapia.
