Perancangan Sistem Kontrol Kincir Air Berbasis Internet Of Things (IoT) untuk Tambak Udang

This research designs and tests an Internet of Things (IoT)-based waterwheel control system for shrimp ponds using a NodeMCU ESP8266 and a relay to control a single-phase induction motor. The system enables remote control of the waterwheel via the Blynk application on a smartphone. Experimental results show that a ½ HP (0.37 kW) motor performs well under different conditions. In no-load condition, the motor operated at 210 V, 2.41 A, consuming 106.28 W with a speed of 4800 rpm. With load (paddle wheel attached), the motor consumed 204 V, 2.83 A, producing 121.23 W with a speed of 3319 rpm. When tested with water load, power consumption increased to 123.9 W at 200 V and 2.95 A, with speed reduced to 2600 rpm. Based on waterwheel requirements, the ½ HP motor is sufficient to drive a paddle wheel of 40–60 cm diameter with 4–6 blades, producing approximately 22.7 Nm of torque. With an automatic operation cycle of 3 hours ON and 1 hour OFF, the system is estimated to consume ±2.16 kWh of energy per day. The system has proven to improve energy efficiency, reduce dependency on manual control, and facilitate sustainable water quality management in shrimp ponds.
