Abstract :
Catfish is a fish that is currently being developed by the Indonesian government to increase production in the fisheries sector. In practice, catfish farmers still carry out conventional feed monitoring by visiting fish ponds. The problem that often occurs is due to daily feed requirements which must be in accordance with the feeding schedule and daily feeding. This becomes an obstacle for cultivator activity which causes time to be ineffective and inefficient. Based on these problems, this study will design a sistem using Loadcell sensors and servo motors that function to monitor and control catfish feeding, by utilizing Google Firebase as a database and an Android application as control and monitoring integrated with the Wifi Module Nodemcu ESP8266. The accuracy of the loadcell sensor for fish feed is very good, which is 97.573%. The accuracy of the servo motor is 98.237%. The result of QoS calculation in the form of Throughput generated is 0.000120026 kbps and is a Bad category on TIPHON. The resulting Packet Loss is 0.012% and is a very good category on TIPHON. The resulting delay of 297.986 ms is in the Good category in TIPHON. Keywords: Internet of Things, Nodemcu ESP8266, Loadcell HX711, Motor servo, Android
