ABSTRACT: Kaliboyo River is an area that has potential by silting due to the deposition of suspended sediments. The potential of this silting can be known by understanding the value of concentration and the distribution of suspended sediment load. The high suspended sediment load concentration in the ocean is influenced by currents generated by tides. The purpose of this research the effect of ocean currents on the concentration and distribution of suspended sediment load in the Kaliboyo River of Batang Regency, Central Java. The material used includes the main data such as water sample, and current. while the supporting data consists of tides data from BMKG, and river discharge from Central Java PSDA in 2017, bathimetry results from September 15, 2018, and RBI 2017 map This study uses quantitative methods that are explorative in nature, taking the location of sampling using the purposive sampling method, taking ocean currents using the lagrange method. The mathematical model used is 2D Flow Flexible Mesh Model for flow direction and Inverse Distance Weighted for TSS distribution interpolation. Based on the results of the study, it was found that the value of the tide suspended solids to tide at the 0.2d level had a value between 0.027 g / l - 0.114 g / l, 0.6d depth had a value between 0.030 g / l - 0.114 g / l, and 0.8d has a value between 0.038 g / l - 0.118 g / l. The current velocity has a value between 0.0181 m / dt - 0.2011 m / dt with the dominant direction to the northwest. Based on the results of the study it can be concluded that the highest concentration of total suspended solid in the estuary of the river and the area where still influeced by the river and shrinking towards the open sea. }, issn = {2407-7690}, pages = {393--401} doi = {10.14710/jmr.v8i4.24775}, url = {https://ejournal3.undip.ac.id/index.php/jmr/article/view/24775} }
