Sea waves are important in the service of marine meteorological data. Waves that occur at sea have random and complex movements, so that the height and period of the waves are difficult to measure and formulate. This study aims to design and create marine instrumentation that can measure and record the parameters of wave height and period of coastal waves in situ so that the data obtained can reflect the conditions on the field well. PVC (Polyvinyl Chloride) is used for the instrument floats. The buoyancy value of the vehicle shows a floating value of 124.97N, or the maximum amount of load that can be accommodated by the vehicle is ±12 kg. This research was conducted from November 2019 until July 2020. The pre-research conducted at the Laboratory of Marine Science and Technology, and Computer Laboratory FPIK Universitas Padjadjaran. Testing laboratory scale carried out in a static pool, Grand Pangandaran, Pangandaran Regency and field testing was conducted in the Area of Pangandaran Port, Bojong Salawe, Pangandaran Regency, West Java for 5 days with each observation time for 6 hours / day. The results obtained are x, y, and z axis data values with a total of ±3600 data. Data analysis is based on the Zero Crossing Analysis statistical using python. The results of data processing showed a wave height value of 10% (H10) with a value of 3.0 meters, and a wave period of 10% (T10) worth 6.87 seconds. Significant wave height (HS) with a value of 2.8 meters, and significant wave period of 6.8 seconds, with an average wave height of 2.7 meters, and an average wave period of 6.8 seconds. This is consistent with the wave data from BMKG which show values ranging from 2.5 to 4 meters, on June 27-30 2020 and July 1, 2020.
