Abstract
The Regional Government of Badung Regency, Bali has initiated an internet of things-based application Fish Go to support fishing activities in the Bali Strait. In implementing this application, a wireless fish finder equipment is built utilizing the hydroacoustic and Arduino technologies as well as Android-based communication devices (handphone). This equipment consists of 3 device components, namely the transducer, transmitter, and receiver. The measured water depth along with objects detected in the water column by the transducer will be processed by a data processing unit installed in the transmitter in order to estimate the presence of schools of fish. Afterwards results sent to the receiver unit using Long Range (LoRa) radio communication technique and transmitted to the fisherman^s mobile phone that has the Fish Go application using Bluetooth technology. This equipment is designed to be used in 2 modes, underway on board or installed stationary using buoy. In order to support the measurable fishing policy implemented by the Ministry of Marine Affairs and Fisheries, this equipment is also equipped with a data storage that is able to store all data measured by the transducers during fishing activities.
