Feb 27, 2025 by ADMIN 57 views

Introduction

Belawan Harbor, located between two open river mouths, faces various environmental and hydraulic challenges. One of the most significant problems is sedimentation, which is a natural consequence of the existence of the port. Understanding the characteristics of sediment in Belawan Port waters is very important so that the development and use of port areas can be done optimally. Therefore, this study focuses on the analysis of sediment characteristics in Belawan Port waters to anticipate sedimentation problems that may arise.

Background of the Study

Belawan Port is a major port in Indonesia, located on the coast of North Sumatra. The port is an important hub for trade and commerce, with a high volume of cargo and passenger traffic. However, the port's location between two open river mouths makes it prone to sedimentation, which can affect the port's operations and the surrounding environment. Sedimentation can lead to the deposition of sediment, which can cause erosion, damage to infrastructure, and harm to marine life.

Methodology

This study was conducted by analyzing sedimentary characters at 20 station points spread along 10 km towards the sea. Various parameters were measured in this study, including sediment size distribution, fall velocity, initial movement (incipient motion), basic charge (bed load), suspended load, total charge (total load), and potential erosion. In addition, other parameters that were also analyzed include tides, waves, wind, temperature, rainfall, sedimentary density, and sea water, and runoff discharge from rivers.

Data Collection and Analysis

The data was collected using a combination of field observations and laboratory analysis. The field observations were conducted at 20 station points, while the laboratory analysis was conducted to determine the sediment size distribution, fall velocity, and other parameters. The data was analyzed using statistical methods to determine the sediment characteristics and the potential for sedimentation.

Results

The results of the study show that the size of the granules at each dominant station consists of fine sand (fine sand), while in the mouth of the estuary identified the existence of fine mud threshold (silt). From this analysis, it was found that the largest depositional location was at stations 3 and 5, while the largest erosion location was detected at station 2. By knowing the standard deviation value, it can be concluded that the condition of Belawan Harbor waters has a good level of sorting in areas far from river mouths, while in the estuary area, the sorting rate is quite bad. This indicates that the Belawan Port waters environment is a deposition environment that needs to be managed carefully.

Discussion

The results of this study have important implications for the management of Belawan Port waters. The study shows that the sediment characteristics in the port waters are complex and influenced by various factors, including tides, waves, wind, temperature, rainfall, sedimentary density, and sea water, and runoff discharge from rivers. The study also shows that the port waters are a deposition environment, which means that sediment is deposited in the port waters, rather than being eroded.

Conclusion

This study provides an in-depth understanding of the sediment characteristics in Belawan Port waters. The study shows that the sediment characteristics are complex and influenced by various factors, including tides, waves, wind, temperature, rainfall, sedimentary density, and sea water, and runoff discharge from rivers. The study also shows that the port waters are a deposition environment, which means that sediment is deposited in the port waters, rather than being eroded. The results of this study have important implications for the management of Belawan Port waters and can be used to develop policies and strategies to mitigate the effects of sedimentation.

Recommendations

Based on the results of this study, the following recommendations are made:

The development of policies and strategies to mitigate the effects of sedimentation in Belawan Port waters.
The implementation of measures to reduce the amount of sediment deposited in the port waters, such as the construction of sedimentation ponds or the use of sediment-reducing technologies.
The monitoring of sediment characteristics in the port waters to ensure that the sedimentation problem is being addressed.
The development of education and training programs for port staff and stakeholders to raise awareness about the sedimentation problem and the importance of managing it.

Future Research Directions

This study provides a foundation for future research on the sediment characteristics in Belawan Port waters. Future research could focus on the following areas:
