The Impact of Sedimentation on the Perak River Shipping Channel on Shipyard Operations

Abstract

Siltation of shipping channels presents significant challenges that can heighten maritime safety and security risks while impeding economic activities. Sedimentation, defined as the deposition process of solid particles including sand and rock materials, necessitates regular maintenance interventions. This phenomenon has been particularly pronounced in the Perak River shipping channel in recent years, with no dredging operations conducted to date. The occurrence of sedimentation significantly impacts the operational activities of shipyard companies located along the Perak River shipping channel. This study aims to investigate the impacts of sedimentation in the Perak River on shipyard operations. The research employs a quantitative methodology utilizing SPSS software for data analysis. The study sample comprises employees from the shipyard companies PT. Dumas Tanjung Perak Shipyard and Pelni Surya Shipyard. Simple linear regression analysis was employed, yielding the equation Y = 5.943 + 1.112X. The findings demonstrate that the impacts of sedimentation on shipping channels exert a positive and significant effect on shipyard operations. These impacts include reductions in the number and size of vessels capable of transiting the channel, as well as increased operational costs for shipyard companies and ship owners due to process delays while awaiting optimal water conditions during highest tide periods.
