Abstract

Pada saat ini sering terjadi kematian ikan yang disebabkan oleh kadar salinitas yang tinggi pada pembudidayaan ikan di tambak. Kadar salinitas yang tidak normal dapat membuat pertumbuhan ikan melambat. Oleh karena itu, para pembudidaya ikan perlu melakukan sebuah pengamatan di tambak agar kualitas air sesuai dengan kebutuhan ikan yang dibudidayakan. Pemantauan ini harus dilakukan setiap hari. Hal ini akan menyulitkan bagi pembudidaya ikan, apalagi jarak tambak dari perumahan yang cukup jauh. Oleh karena itu maka diperlukan suatu alat yang bisa memantau maupun mengontrol kadar salinitas dari jarak yang jauh tanpa perlu datang ke lokasi tambak. Pemantauan dan pengontrolan dilakukan dengan membaca sensor salinitas air tambak menggunakan Sensor Total Dissolved Solid (TDS). Data pembacaan sensor TDS diolah oleh sebuah microcontroller Arduino Uno kemudian LoRa Transmitter akan mengirimkan datanya ke LoRa Receiver. Setelah data diterima di receiver data akan dikirimkan melalui Node MCUesp8266 ke aplikasi Blynk yang ada di perangkat kita. Sedangkan untuk sistem kontrolnya menggunakan kontrol Proportional Integral Derivative (PID) untuk mengatur relay. Relay ini mengatur lama bukaan valve untuk membuka atau menutup, menambah maupun mengurangi kadar salinitas pada air. Pengujian sensor salinitas dilakukan di berbagai salinitas air mulai dari 0ppt sampai 40ppt. Dari hasil yang didapat, sensor TDS ini mampu membacanya dengan baik. Untuk LoRa sendiri mampu mengirimkan datanya dengan baik pada jarak kurang lebih 600 meter. Pada pengujian keseluruhan sistem di Tambak didapatkan nilai standar deviasi eror ketika kondisi mulai stabil sebesar 0.2415 ppt.

At this time fish death often occur due to high levels of traffic in fish farming in ponds. Abnormal levels of salinity can make fish growth slow Therefore; fish farmers need to make an observation on the pond so that the water quality is in accordance with the needs of the fish being cultivated. This will make it difficult for fish farmers, especially the pond distance from housing that is quite far away Therefore, we need a tool that can monitor and control salinity levels from a long distance without the need to come to the pond location. Monitoring and control is done by reading the pond water salinity sensor using the TDS sensor. The TDS sensor reading data will be processed by an Arduino UNO microcontroller then the LoRa Transmitter will send the data to the LoRa Receiver. After the data is received at the receiver, the data will be sent via the MCUesp8266 node to the Blynk application on our device. Meanwhile, the control system uses PID control to regulate the relay. This relay regulates the length of the valve opening to increase or decrease the salinity level in the water. The salinity sensor test is carried out in a variety of water salinity ranging from 0ppt to 40ppt. From the results obtained, the TDS sensor is able to read it well. LoRa itself is able to transmit data well at a distance of approximately 600 meters. In testing the whole system in Tambak, the standard deviation value of error was obtained when conditions began to stabilize at 0.2415 ppt
