MODELING OF BEACH CHANGE AND TOTAL SUSPENDED SOLID DISTRIBUTION BASED ON REMOTE SENSING DATA BEFORE AND POST RECLAMATION IN LAMONG BAY PORT

Teluk Lamong Harbor is one of the reclamation areas which is affecting the marine environmental resources. Therefore, an analysis of shoreline changes, current pattern modeling, Total Suspended Solid (TSS) modeling based on remote sensing data is used to see the results of the development of the Teluk Lamong Multipurpose Port Terminal. The objectives of this study are analysing the shoreline changes in the Multipurpose Port Terminal in Lamong Bay in 2012 (before reclamation) and 2020 (after reclamation), analyzing the modeling of current patterns in the Multipurpose Port Terminal in Lamong before and after reclamation, analyzing the use of TSS analysis in the Multipurpose Port Terminal in the Lamong Bay before and after reclamation. Stages of the method are analyzing shoreline changes using the Digital Shoreline Analysis System (DSAS) software before and after reclamation, modeling the flow pattern using Mike 21 software before and after reclamation, and modeling the use TSS uses Mike 21 software based on remote data sensing using Google Earth Engine (GEE). The EPR values are 107.5 meters/year, 59.63 meters/year and 10.38 meters/year. The remote sensing TSS values which need to be considered are on the condition of very low values (0-20 mg/L), low (20.1-40 mg/L), moderate (40.1-80 mg/L), high (80.1-120 mg/L) and very high (>120.1 mg/L). For the total suspended solids, informs that the highest value is at a point near the Teluk Lamong Port based on the in-situ data where the high TSS values at stations 2, 3, 4, 22 and 23 with values of 142 mg/L, 119 mg/L, 115 mg/L, 112 mg/L, and 116 mg/L. However, comparing with the remote sensing data in 2020 using GEE TSS software shows the values on 167 mg/L, 122 mg/L, 120 mg/L, 128 mg/L and 120 mg/L. In 2012, TSS in low tide reaches 320-360 mg/L and in high tide reaches 325-350 mg/L. In 2020, TSS in low tide reaches 360-400 mg/L and 440 mg/L in high tide. Both previous papers and the recent analysis on this research give a similar result. Therefore, it may consider that the recent result as the updated condition from the development of Teluk Lamong Harbour.
