Abstract. Many ports in Indonesia who have problems with limited dock land, yard and warehouse and equipment. There is a dock that has good equipment, but Yard Occupancy and Berth Occupancy ratio are high ratio. Boom Baru port in the city of Palembang, in Indonesia, has good hinterland and the number of ship visits is quite high, but can not increase productivity or capacity of the port due to the rapid sedimentation of the port basin and land constraints to accumulation of goods. In this study, the method used to determine the condition of the real problems of sedimentation conducted through analysis of sediment concentration and sediment discharge a total of either scenario sediment from upstream (river) as well as the source of sediments estuary (port basin) [1] . By knowing the pattern of flow and sediment caracteristic process of sedimentation and erosion in the estuary, can be calculated by the method of Yang [2] .The calculation and analysis show that the sedimentation on the Musi river is high enough where the sludge reaches 40 cm/month. While the volume of sedimentation in the pools of Boom Baru port calculated using the Yang method, amounting to 13,081.42 m3/year.
