Abstract

Traffic congestion has become one of the main issues faced by the city of Medan, in line with the growth of population and vehicles. The Medan City Government has taken various measures to address this issue through the development of transportation infrastructure, including the construction of underpasses at several strategic points, as well as the introduction of electric buses as an alternative mass transportation. Infrastructure development, such as the underpass on HM Yamin Street, has proven effective in reducing congestion in critical areas. Additionally, the operation of electric buses provides an environmentally friendly solution that can reduce the density of private vehicles and greenhouse gas emissions. This study aims to analyze the efforts of the Medan City Government in improving the transportation system and reducing traffic congestion through infrastructure projects and mass transportation. The results of the study show that these measures have a positive impact on traffic flow and travel time efficiency, although challenges remain related to the increasing volume of vehicles. In the future, the development of a more integrated mass transportation system is necessary to ensure the sustainability and long-term success of these effort.

Abstract

The implementation of canal construction with an alternative method is to use Geosynthetic Cementitious Composite Mats (GCCM) which is a relatively new technology in industrial construction consisting of synthetic materials (geosynthetic) and cement concrete (cementitious). The GCCM method offers potential advantages over conventional methods, including faster construction time, lower maintenance costs, lower risk of environmental damage, and more consistent and durable channel quality. This study aims to highlight and compare the effectiveness of conventional methods and Geosynthetic Cementitious Composite Mats (GCCM) methods in canal construction. The results of the study indicate that the GCCM method has advantages in terms of structural strength, erosion resistance, and reduced environmental impacts compared to conventional methods. The results of physical tests show that GCCM significantly increases slope stability by reducing soil stoppage up to eight times compared to conventional methods. Under seepage flow conditions, slopes stabilized with GCCM remain solid without structural failure, while slopes with conventional methods experience total collapse. In terms of cost, although the price of GCCM material is higher, savings in labor and implementation duration make it more economical for large-scale projects. The results of this study can be a reference for practitioners and decision makers in choosing the right canal construction method for national strategic projects
