Abstract

This research focuses on the design and optimization of a trash comb for the river trash collector conveyor used on the Malacca River boat. The study addresses pollution concerns and inefficiencies in existing trash collection systems, aiming to create a more effective and sustainable solution. Using SolidWorks software, the project involved redesigning the trash comb, analyzing its structural performance, and optimizing it for enhanced functionality. Evaluations were conducted on stress, displacement, strain, and factor of safety to ensure the design’s mechanical integrity and durability. The existing design, made from plain carbon steel, demonstrated limitations in corrosion resistance, longevity, and operational efficiency in marine environments. To overcome these issues, the improved design employed galvanized steel, which offers superior durability and resistance to corrosion. The optimized design features precise spacing and geometry, ensuring efficient debris collection while minimizing blockages and enhancing overall system reliability. These improvements not only increase the operational lifespan of the system but also reduce maintenance requirements, making it a cost-effective solution. The results confirm that the optimized design significantly outperforms the original in all evaluated aspects, including durability, environmental sustainability, and efficiency. By addressing key challenges in waste collection, the improved trash comb design provides a practical and robust solution to managing river pollution. This study successfully achieves its objectives, contributing to sustainable waste management practices and offering a valuable improvement to river cleanup operations.
