Abstract
Cirebon port is one of the largest port in West Java province which plays a major role in supporting the surrounding economy and becoming the alternatives of the biggest port in Java. Numerous loading and unloading activities are recorded with coal as one of the commodities. Sedimentation and water quality is a common issue facing any port. To assess the recent condition of the port, an oceanographic parameter and hydrography survey is one approach. A field survey in the Cirebon port, particularly around the channel and outside part was carried out. The bathymetry result at the channel varied within 0 - 8 m depth. The mixed semidiurnal type in this area has a tidal range around 1.1 m. Sea current inside the port has low speed within 0-3 cm/s meanwhile outside of the port can reach 0.18 cm/s. Through the weathering system, the average temperature is 26.3 C, average wind speed of 2.5 m/s dominantly blowing from northeast, relative humidity around 88.6%, and rain rate also low. In the study, the sea condition of temperature, salinity, pH, turbidity, and DO is 28.4 - 29.86 C, 29.6 - 30.2 PSU, 7.8 - 8.3, 2.1 - 31 FTU, and 3.52 - 4.87 respectively. Based on the conformity of standard water quality, the condition for the port is within threshold for several parameters.
