Study about sea level change, which can give negative effect to coastal areas and small islands, requires information of Sea Level Anomaly (SLA) variation. The information derived from sea level observations, both using altimetry satelitte and local tide gauges. As a dynamic component, SLA is represented by the difference between Sea Surface Height (SSH) and Mean Sea Surface (MSS). <br /> <br /> <br /> <br /> <br /> <br /> <br /> This research aims to statistically describe SLA, identifying temporal variation of SLA, and analyzing variables that cause variation of SLA in the study area over the western Java Sea. Statistical descriptions, such as minimum, mean, and maximum value, is the methods that are used in this research. Transformation of time series domain into frequency domain based on Fast Fourier Transform (FFT) is also used in the analysis. <br /> <br /> <br /> <br /> <br /> <br /> <br /> The result of the statistical description shows that SLA variation has the minimum value of -0.525 m, average value of 0.002 m, and the maximum value of 0.397 m. Based on the temporal variation of SLA over the western Java Sea, the dominant phenomena that affect SLA consist of sun position above the equator (6 months period), monsoon phenomenon and earth position relative to the sun in the form of equinox and solstice (1 year period), and also El Niño Southern Oscillation or ENSO (2-5.5 years period).
