- Ikan Cupang (Betta splendes) merupakan salah satu ikan hias air tawar yang banyak dibudidayakan oleh masyarakat Indonesia. Kualitas air yang tidak sehat dan tidak sesuai dengan keadaan habitat aslinya mempengaruhi cupang, akibatnya ikan rentan terhadap penyakit sehingga ikan mudah mati. Oleh karena itu, adanya sistem monitoring menggunakan ESP32 dan Arduino nano berbasis internet of things (IoT) dapat memantau suhu dan pH air setiap saat secara real time, sehingga dapat membantu dalam merawat ikan cupang. Suhu dan pH diukur menggunakan sensor-sensor, masing-masing sensor terhubung ke Arduino nano, kemudian data yang didapat dari arduino dikirim ke ESP32, kemudian di kirim ke cloud firebase, data dapat diakses melalui aplikasi Android. Dengan menggunakan metode eksperimen dalam penelitian ini, alat diuji pada akuarium yang dipantau secara real time. Penelitian ini dilakukan selama 7 hari, nilai suhu yang ingin dicapai berkisar antara 24-30 ℃ dengan pH berkisar 6,2-7,5. Nilai suhu air berkisar 27 – 29 ℃ di pagi hari, dan 29 – 31 ℃ di sore hari. Nilai pH air di hari pertama 7,10 (normal), di hari ketiga pH air menurun hingga 5,10 (asam) kemudian dilakukan pergantian air hingga pH menjadi 7,25 (normal). Berdasarkan data hasil tersebut dapat dikatakan bahwa alat dan aplikasi monitoring kualitas air ikan cupang menggunakan ESP32 dan Arduino nano berbasis IoT berfungsi dengan baik.

Betta fish (Betta splendes) is one of the freshwater ornamental fish that is widely cultivated by the people of Indonesia. Water quality that is not healthy and not in accordance with the state of its natural habitat affects the betta, as a result the fish are susceptible to disease so that the fish die easily. Therefore, there is a monitoring - based ESP32 and Arduino nano internet of things (IoT) can monitor the temperature and pH of the water at any time in real time, so it can help in treating betta fish. Temperature and pH are measured using sensors, each sensor is connected to the Arduino nano, then the data obtained from the Arduino is sent to the ESP32, then sent to the firebase cloud, the data can be accessed via the Android application. Using the experimental method in this study, the instrument was tested in an aquarium that was monitored in real time. This research was conducted for 7 days, the temperature value to be achieved ranged from 24 - 30 with a pH ranging from 6.2 to 7.5. Water temperature values range from 27 – 29 in the morning, and 29 – 31 in the afternoon. The pH value of the water on the first day was 7.10 (normal), on the third day the pH of the water decreased to 5.10 (acidic) then the water was changed until the pH became 7.25 (normal). Based on these data, it can be said that the monitoring using ESP32 and Arduino nano based on IoT function well.
