This study focused on the design review and evaluation of silt curtainSilt curtain and geotextileGeotextile systems as filter layers designed to minimize the environmentalEnvironmental impact of dredgingDredging projects. Using a case study of the capital dredgingDredging project at Kalibaru terminal 1B, port of Tanjung Priok, Jakarta, two layers of silt curtainsSilt curtain were installed along the 1500 m northern perimeter of a near-shore dumping area, which was semi-exposed to the Java sea at a current speed of 0.5 m/s and a design wave height of 0.63 m. The geotextilesGeotextile as a filter layer are placed on the backside of the rubble mound breakwater, located on the western and southern sides of the dumping site, with a total length of 2380 m. Throughout the duration of the project, daily total suspended solid (TSSTSS) measurementsMeasurement are used to monitor the water turbidity outside the dumping area. The observed TSSTSS concentrations range from 1–6 mg/l, lower than the Indonesian quality standard of 80 mg/l. Therefore, installing silt curtainsSilt curtain and geotextileGeotextile filter layers was concluded as an effective effort to prevent the spread of sediment outside the disposal area.
