Design, construction, and stability test of aerial wireless coastal buoy

Abstract

Abstract Due to its highly dynamic nature, coastal waters are necessary to be continuously monitor. Aerial wireless coastal buoy (AWCB) is one of the ocean instrument commonly deployed for observing oceanographic phenomena in coastal waters and around small islands. In this paper we describe the design, construction and the stability test result of new AWCB. The new AWCB is using water temperature sensors to collect data and transferring them through specific aerial wavelengths at real time and low cost in coastal areas. The AWCB is completed three steps. First, the buoy was designed using CAD software to determine its size, form and color. Next, the buoy was constructed using material from fiberglass. Last buoy was tested for its buoyancy and stability at the Acoustic and Instrument Laboratory, Faculty of Fisheries and Marine Sciences, Bogor Agricultural University. At sea-trial was also carried out around Pramuka Island, and during the trial it shows that the buoy is stable condition within waves swaying and surface water current. It is floating well on seawater surface and stable for six days installing duration.
