Waves in the sea have a random shape, where the height, length, and direction of the waves change during the observation time. Due to the unpredictable nature of the waves with certain patterns, a statistical and probability approach is needed in analyzing waves. Before carrying out statistical and probability analysis, it is necessary to extract the wave parameters from the random wave data. There are two methods commonly used to extract wave parameters: the first is the individual wave analysis method, using a zero up/down-crossing technique. The second method is the wave spectral analysis method. In this study, both methods will be applied to observation data from the Pabelokan station [1] in the West Java Sea for a six-day. From this study, it was found that the significant wave height parameter generated by the spectral analysis technique and the zero up-crossing technique showed a positive correlation, which the correlation coefficient is 0.9891. In the study of the wave period investigation, both of method have a positive correlation, but the value of the wave period is very likely to be different. The correlation coefficient values for the average wave period are 0.5848 for Tm01 and 0.5757 for Tm02 .
