Abstract

TPPI Tuban Port is located in Tuban Regency, East Java. Geologically, the rocks are composed of reef limestone in the Paciran Formation, which is Pliocene–Early Pleistocene. The importance of complying with jetty capacity standards and water conditions in commercial ports is emphasized as the key to maintaining smooth port operations, making port revitalization a necessity. One of the main aspects to consider is the sedimentation problem, closely related to sediment characteristics. A deep understanding of sediment dynamics is essential for designing effective solutions to ensure the sustainability of port operations. This research aims to determine the distribution pattern of bed load characteristics such as water content, specific gravity, gradation, sediment texture, d50 size of sediment grains, and statistical analysis of bed load sediment in the west and rainy seasons, where the influence of sediment from land is very large. so it is hoped that it can support the port revitalization plan. The methods used include taking sediment samples in the field, testing sediment samples in the laboratory, statistical sediment analysis, and descriptive analysis of bed load characteristics using the Gradistat method. Based on the study results, the water content value ranges from 22.446% to 218.289%, and the specific gravity ranges from 2,100 g/m³ to 2.690 g/cm³. Additionally, the grain size varies from 0.080 mm to 0.900 mm, and the average grain size ranges from 261.1 μm to 2657.5 μm. Sediment sorting is dominated by very poorly sorted materials, with statistical analysis indicating a dominance of the very platykurtic type. The lithological type is predominantly sand.

Abstract

The proposed National Capital Integrated Coastal Development (NCICD) Program envisions a Coastal Reservoir (CR) in the Tanjung Pasir waters of Banten, Indonesia, as a critical component to address pressing environmental challenges in the Jakarta Bay area. This multi-functional CR aims to secure raw water supply and mitigate saline water intrusion into coastal aquifers. A primary concern in the design and long-term viability of this CR is sedimentation, directly influenced by suspended sediment concentrations (SSC). This study presents a basic characterization of suspended sediment dynamics in the Tanjung Pasir waters. Utilizing a methodology encompassing in-situ sampling, laboratory analysis, and data interpretation, the findings revealed an average SSC of 89.31 mg/L, with a range of 5-200 mg/L. These concentrations align with Indonesian Government Regulation PP 22 of 2021, indicating suitability for various uses including aquaculture, tourism, and port activities. Notably, suspended sediment concentrations at the near-bed layer (0.8d) were marginally higher than those observed in the mid-depth (0.6d) and surface (0.2d) layers, suggesting a typical vertical distribution pattern influenced by hydrodynamic forces. This research produced very important empirical data as a basis for designing and validating action research on suspended sediment management, which aims to improve CR design parameters, predict sedimentation rates, and ensure the long-term operational sustainability of this infrastructure.
