Abstract

The maintenance dredging work at Ulee Lheue Port aims to maintain optimal water depth for navigation activities. However, this activity involves various risks that must be systematically identified and managed. This study employs the IBPRP (Hazard Identification, Risk Assessment, and Opportunities) method to analyze potential risks in the dredging process.The analysis results indicate four major risks, consisting of two medium-level risks and two high-level risks, with no low-level risks identified. The high-level risks have the potential to significantly impact the stability of the port basin and worker safety. To mitigate these risks, strategies adhering to occupational safety standards and environmental protection measures are implemented, such as the adoption of safer dredging technologies, strict operational supervision, and workforce training.By implementing appropriate risk identification and mitigation measures, the dredging process can be carried out more safely, efficiently, and sustainably. This study is expected to serve as a reference for port management in designing more optimal and risk-based dredging strategies

Abstract

This research was conducted in February 2021 at the mouth of the Dumai River, Rupat Strait. The purpose of this study was to determine the effect of sediment supply from land on changes in bathymetry in the waters of the Rupat Strait based on the analysis of suspended sediment (SSC) and suspended solids (TSS) divided by the area of the study. The method used is a survey method. The results showed that as much as 26,94 tons/year of sediment entered the Rupat Strait and was distributed in the research area. Each part of the research area has a different bathymetric change value. This is presumably due to oceanographic factors in the waters of the Rupat Strait such as strong and weak river currents when entering the sea, the distance between the research area and the sediment supply source, human activities in each part of the study area, erosion along the river and abrasion at the river mouth. the presence of mangrove forests, dominant sediment types, sloping water topography, the cross-sectional width of the river as a sediment supplier, and suspended solids.

Abstract

This research was carried out in December 2021-January 2022 in Dumai City District, Riau Province. The purpose of this study is to determine the rate of sea level rise based on analysis of tide data from 2001-2021 and to predict inundation areas in the next 20 years. This research method is a descriptive survey using remote sensing as an additional tool to show the results. Acquisition needs are in the form of primary data (land use and tide data) and secondary (slope data, elevation, land use, and tide data). These parameters are processed and analysed to describe the extent of the inundation by displaying a map of the City of Dumai. The results showed that the waters of Dumai City have a Formzhal number of 0.5, which means that the water area is classified as a mixed tide, semi-diurnal prevalence, with a sea level rise of 2.003 cm/year. Then, the numbers used to predict the height of sea level rise in the next 20 years are 0.973 m each. Furthermore, sea level height was analyzed to obtain the inundation area for the next 20 years, it turns out that the inundation area each year is 11.89 ha.

Abstract

Sungai Selari Village is an area in Riau Province that features a high density of water activities, including a port where many fishing boats are moored and also serves as a transportation route for fishermen seeking fish. This activity can cause water pollution, which leads to the silting of waters through sedimentation. The activity of sediment input into a body of water can cause changes in the ecosystem, including alterations in sediment texture, organic matter content, and the abundance of macrozoobenthos biota. One organism that can be affected by differences in ecosystems is the macrozoobenthos due to its sedentary nature. This study aims to determine the type of sediment, grain size, and organic matter content, as well as their relationship with macrozoobenthos abundance. This research was conducted in March and April 2023, utilizing purposive sampling techniques at four stations in total. The samples taken were sedimentary substrates and macrozoobenthos. The results indicated that the size of the dominating sediment stalk, specifically the mud fraction, ranged from 14.72% to 71.25%. The types of macrozoobenthos found are grouped into two classes, namely Gastropods and bivalves. Individual abundances range from 0.3 - 4.4 ind/m2, with the highest abundance occurring at station 4 and the lowest occurring at station 1. The organic matter content ranges from 9.27- 34.2%. The relationship between organic matter content and macrozoobenthos abundance exhibits a moderate correlation of 0.506. The relationship between sediment grain size and macrozoobenthos abundance shows a fairly close correlation of 0.544
