Kajian Teknologi Sand by Passing Penanggulangan Sedimentasi dan Erosi Pantai Bengkulu (Pelabuhan Pulau Baai)

Abstract

Curently the port flow conditions Baai Island can no longer be passed if the large size of the ships that will stop at the port. This is because the rut depth at this point is just -2m until -4m LWS, from a normal condition that should be -10m until -12m LWS.This situation is certainly very disturbing process of exit and entry of goods and service to the province of Bengkulu throught this port, and negatively impact the local economy.The aim of this thinking is to provide input for the achievement of an optimal solution to overcome sedimentation arround Baai island port Bengkulu to know the behaviourof the sedimentation ponds arround the harbour entrance and the effect on navigation channel.The scope of research is supporting data collection relating to the port Baai Island Bengkulu including development planning reports, Baai harbour and reports on the sedimentation and the condition of the harbour. The method of analysis used in this study were laboratory analysis techniques. Analysis of what has been  studied to mentionthat the large amount of sedimen transport (litoral transport) along the coast of the port based on wave direction,among others from the west and south-west and north, are as follows: 1) total sediment transport (Qs) which took place on the beach ports Baai island is: 601,576.20m³/year. 2)The sediment transport that provides the greatest contribution to the sedimentation flow Baai harbour island is the result of calculation is from the west (toward the most dominant),namely: Qs-net = 573,916.72 m³/year.
