Abstract

Binjai is a city in North Sumatra. Along with the increase in population and the increase in industrial zones every year, automatically the need for the use of clean water continues to grow. In East Binjai Subdistrict, the existence of Drinking Water Service Providers is far from satisfactory. This happens because many residents still use groundwater sources (dug wells) as one of the main sources of residents to obtain clean water. By thinking about these problems, the author wants to evaluate the need for clean water in East Binjai District until 2027 and the number of clean water service coverage in East Binjai District in 2027. Based on the results of research that has been carried out, the need for clean water based on the total population of East Binjai District in 2027 is 109,612 lt/s, while clean water needs are based on the number of customers of East Binjai District in 2027 of 18,018 lt/s. As for the service coverage of Company M in 2027, it was obtained by 17.946%, with the description of 66,227 people in the total population of East Binjai District, the number of people who use Company M's services for daily use is only 11,326 people. The remaining 54,342 people still use independent methods to obtain clean water.

Abstract

The potential for waste and biomass definitely exists in every region, because every day humans naturally produce waste to meet their needs. However, the potential for waste and biomass in each area is different in proportion to the population. As the population increases in each region, the potential for waste and biomass produced also continues to increase. This research aims to: (1) Create a design for sorting organic and inorganic waste, and (2) Find out how the organic and inorganic waste sorting equipment works. The waste used includes cardboard, leaves, paper, wood twigs and banana peels for organic waste, as well as plastic, bottles, iron, cans and plastic bottles for inorganic waste. After designing and testing the sorting tool, the conclusion was that the design of the tool with the three tool sensors used was successful in differentiating the types of organic and inorganic waste so that the organic waste valve or inorganic waste valve would open according to which type of waste detected it fell into which category, then Monitoring the contents of the trash can will appear on the LCD and the recommended distance for organic waste with a sensor is less than 27 mm and for inorganic waste with a sensor is less than 3 mm.

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
