Looking forward to the abovementioned conditions, this research is needed to elaborate on the effects of the reclamation to the marine resources in Teluk Lamong Multipurpose Port Terminal as the reclaimed product. In order to describe the impact of the port development, this study will analyze the shoreline changing, the current pattern modeling, as well as the Total Suspended Solid (TSS) modeling using the remote sensing data. The several numbers of expected objectives through this study are to get the set of scientific information on the shoreline changing in Teluk Lamong Multipurpose Port Terminal in the year of 2012 and 2020, to get the figure of current pattern in Teluk Lamong Multipurpose Port Terminal in the year of 2012 and 2020, and to elaborate TSS concentration through the modeling approach in Teluk Lamong Multipurpose Port Terminal in the year of 2012 and 2020. Hence, there is a set of methodologies and tools to cooperate with the information before and after the reclamation. The use of the Digital Shoreline Analysis System (DSAS) software to analyze coastline conditions. The using of Mike 21 to analyze the current pattern and TSS concentrations. In addition to the TSS analysis, it will also need a set of remote sensing data from the Google Earth Engine (GEE). The modeling and calculation give information about the End Point Rate (EPR) values and TSS values. The EPR values are 107.5 m/year, 59,625 m/year and 10,375 m / year. The TSS values are 0-20 mg/L, 20.1-40 mg/L, 40.1-80 mg/L, 80.1-120 mg/L and >120.1 mg/L. Moreover, the result shows the different values among the length of coastline, the current pattern, and TTS in the years 2012 and 2020. The difference in the coastline reaches 950 m at this latest 8 years. While it also brings the changing to the current pattern and sediment transport which show through its current velocity and sediment content per liter of seawater during high and low tide accordingly.

The coastal area of Cilacap Regency in Indonesia has an important role in increasing activity, economy and ecosystem. The research location is in the southern coastal area of Java and directly faces the Indian Ocean. This can lead to dynamic marine phenomena and cause various kinds of sedimentation problems. To analyze the phenomena that occur in Cilacap seawater, a numerical model is applied to obtain optimal results. MIKE21 software with Hydrodynamic and Sand Transport modules were used in this study to analyze the flow patterns and sediment transport that occurred. The model was built with Cilacap waters as the boundary and was made within 30 days. The result obtained is the model validation using the RMSE method shows a value of 16.33% so that the model is included in the good category. The average direction of the current pattern from the results of the model leads to the west and northwest. The current velocity at ebb is greater than at tide. The most significant bed level changes occurred at the mouth of the Serayu River and the east side of the breakwater.
