Abstract
This research aims to design and implement a water quality monitoring system in aquaculture that will be implemented in SME. Subang is a city which has a lot of potential fish farming in ponds, one of them is Rojo Koyo SMEs. The farmer has a problem, especially in the rainy season, mortality of fish increases and they don't know why this happens. This research aims to solve this problem by making a monitoring system to know the water quality in ponds at low cost because the system will be implemented in SME with small capital. Aquaponics system is an integrated system between fish farming and cultivation without soil. Aquaponics systems need continuous monitoring of water parameters to determine the suitability of the type of fish with the type of plant. The author has developed a low-cost IoT system that can monitor aquaponics system parameters such as temperature, pH and TDS via android platform. Hardware design using several integrated sensors is water temperature sensor type DS18B20, pH type SKU: SEN0161, sensor TDS type SKU: SEN0244. Android software design using C Language for programming. The author using an additional NodeMCU ESP8266 that can transmit data to a smartphone using an internet connection. Data can be accessed using Android with the Blynk app. The cost requirement to develop this device is low cost which is 83.79 USD. Components on the device are easily available in the market so that replacement parts can be done easily every 2-3 years
