Abstract

Road network data and information and spatial supporting infrastructure are important to a road database management planning process. Medan Amplas District, Medan City has a road network divided into national authority roads, provincial roads and city roads, which is 143.14 km. The study area in this research is a flexible pavement-type secondary local road with a length of 33.12 km. The method used in this research is the Surface Distress Index (SDI) Method. SDI divides road conditions into 4, namely good condition, moderate condition, lightly damaged condition and heavily damaged condition. According to RCS or SKJ 2011, there are only 4 elements that are used as support for calculating the SDI value, namely % crack area, average crack width, number of holes, and average rutting depth. From the results of the analysis of the level of road damage in secondary local roads with flexible pavement type in Medan Amplas District, namely 51 road sections in good condition (98%) and 1 road section in fair condition (2%). It can be concluded that the condition of Secondary Local roads in Medan Amplas District is in good condition and only requires routine maintenance at certain points on each road section. The condition of the Secondary Local roads in Medan Amplas District using the SDI Method is in Good Rating, but the Denai River Inspection Road section has a rating of moderate damage.

Abstract

Project schedules are generally created manually, which may lead to delays during the implementation on-site. It is due to the non-inclusion of the uncertainty factor in planning the project schedule. Delays in accomplishing one activity will result in delays in the next one. This study was intended to conduct rescheduling process to minimize the delay in the implementation of the Savanna Sumatera Bridge Project. The study applied PERT method in the rescheduling exercise by using three times conjectures on each project work item, which are: optimistic duration, most likely duration, and pessimistic duration. The results showed that the project was completed in 162 working days with a probability of completion of 99.9%, 34 days faster than the target project duration of 196 working days.

Abstract

Currently, PDAM Tiratasari is facing significant challenges in providing optimal drinking water services to the residents of Binjai City. The main issues stem from the low level of service caused by limited production capacity and an inadequate distribution pipeline network. This situation arises because PDAM Tiratasari relies solely on a single Water Treatment Plant (IPA), namely IPA Marcapada, which is insufficient to meet the growing demand for clean water in line with population growth and regional development. As a strategic effort to increase production capacity and expand the distribution network, the Regional Drinking Water Supply System (SPAM) Program for the Mebidang area—covering Medan, Binjai, and Deli Serdang—has become an essential solution. The Mebidang SPAM, sourced from the Bingei River in Binjai City, has been inaugurated and is designed to serve up to 88,000 household connections or approximately 440,000 people, with a production capacity of 1,100 liters per second. This program is the result of synergy between the central, provincial, and local governments, and is expected to significantly improve access to safe drinking water, particularly in the priority development areas of Binjai Utara and Binjai Timur subdistricts. This study aims to determine the priority areas for the development of the Main Distribution Network (JDU) of the Mebidang SPAM in Binjai City, in order to support improved water service delivery amidst the government’s policy of budget efficiency as stipulated in Presidential Instruction Number 1 of 2025. The analysis employed includes a technical hydraulic scheme analysis using the EPAnet application to model water distribution, as well as the SMART (Simple Multi Attribute Rating Technique) method to determine area priorities based on technical criteria, community needs, and budget efficiency. Through this approach, it is expected that the JDU development can be implemented effectively, efficiently, and accurately, in accordance with community needs and government policies.

Abstract

In 2021, the service coverage of PDAM Tirtanadi’s water supply system reached 73.3%. To further improve the service capacity, a new raw water source was developed through the construction of the Mebidang Regional Water Supply System (SPAM), which draws water from the Bingei River in Binjai City. The PDAM Tirtanadi branches directly affected by this change in raw water source include the Sei Agul and Diski branches. This study aims to evaluate customer satisfaction levels with the water product quality and service performance of the Mebidang SPAM at PDAM Tirtanadi. The methods employed include the Customer Satisfaction Index (CSI) and Importance and Performance Analysis (IPA). Data were collected through questionnaires distributed to both existing customers and new service connections at the Diski and Sei Agul branches of PDAM Tirtanadi. The results showed that customer satisfaction levels were as follows: long-term customers at the Diski branch scored 83.56%, new connections at Diski 83.57%, long-term customers at Sei Agul 82.78%, and new connections at Sei Agul 92.26%. These results indicate that both long-term and new customers at the Diski and Sei Agul branches are generally satisfied with the overall service quality. Based on the IPA results, the main priority for improvement at the Diski branch concerns the imbalance between the cost paid by customers and the volume of water received. Meanwhile, for the Sei Agul branch, variables categorized as low performance and low importance but still of lower priority include PDAM’s responsiveness to customer requests, such as for new connections or meter repairs.

Abstract

The Medan City Government plans to make infrastructure changes by building underpass at the existing signalized intersection between Road Ir. H. Juanda and Road Brigjend. Katamso to reduce traffic congestion. In recent years, vehicle emissions have become a global concern due to their significant impact on public health and environmental quality. As road traffic and vehicle numbers continue to grow, transportation has become a key contributor to air pollution from vehicle exhaust emissions. Consequently, it is essential to assess whether the infrastructure changes from signalized intersection to underpass have an impact on vehicle exhaust emissions. The impact analysis of infrastructure changes on vehicle exhaust emissions is evaluated through traffic simulation using PTV Vissim software with two scenarios, namely the do nothing scenario (existing signalized intersection) and the do something scenario (underpass) ), focusing on CO, NOx, and VOC emissions. The comparative results indicate substantial changes: CO emissions declined by 42.5% (from 40,991 grams to 23,567 grams), VOC by 37.1% (from 9,500 grams to 5,975 grams), while NOx emissions increased by 23.3% (from 7,075 grams to 8,725 grams). These findings suggest that the infrastructure changes from signalized intersection to underpass can positively influence air quality by reducing specific pollutants. However, further studies are necessary to examine its broader impact on other types of vehicle exhaust emissions using diverse emission categories, multiple calculation approaches, and various analytical methods for comprehensive comparison.

Abstract

Medan City is one of the metropolitan cities with a high level of congestion and population density, resulting in traffic jams, delays, as well as air and noise pollution. This study aims to analyze the performance of intersections on S.M Raja – Halat road, Brigjend Katamso – Mesjid Raya road, and Brigjend Katamso - Pelangi road before and after the operation of the underpass at the Ir.H.Juanda – Brigjend Katamso road intersection using vissim software. Data were obtained from traffic surveys such as vehicle volume surveys, road geometry, traffic signal cycle times, and vehicle speeds. The data obtained from the vissim software simulation results include queue lengths, delays, and level of service at the intersection. For the simulation results at the Ir.H.Juanda – Brigjend Katamso road intersection before the operation of the underpass, the average queue length was 274.3 m and the average delay was 307.38 sec/vehicle, with an average level of service of F (very poor). After the operation of the underpass, the average queue length was 8.38 m and the average delay was 0.96 sec/vehicle, with an average level of service of A (excellent). With a 5-year scenario, the average queue length was 38.53 m and the average delay was 12.34 sec/vehicle, with an average level of service of B (good). Thus, a significant difference is clearly visible between before and after the operation of the underpass, such as the results of queue lengths, delays, and service levels, which have caused new conflicts at the intersections closest to the underpass.
