Evaluation of a New Integrated Marine Instruments: RHEA (Drifter GPS Oceanography Coverage Area)

Marine instrumentation is used to make optimal use of natural resources in the marine sector in the form of storing oceanographic characteristics data. This research aims to evaluate a new Lagrangian instrument called RHEA, developed by the Marine Research Laboratory, Padjadjaran University. This research was conducted by examining the correction factors contained in the RHEA from the mechanical and electronic side to optimize the work and carry out appropriate validation of the oceanographic parameter data. The method used is by studying marine instrument literature and conducting a series of tests on the tool until it is ready for use at sea. The output of this research is in the form of literature on how the device works to be effective and efficient in collecting data about certain oceanographic factors. The result shows that RHEA has various functions: measuring pH, dissolved oxygen, temperature, turbidity, and salinity in real-time time. This instrument needs to be slightly modified again related to its design so that it can be more optimal when measuring oceanographic parameter data. In addition, in terms of data acquisition, it is necessary to improve the electronic components by replacing or adding several parts so that the data obtained can have high accuracy.
