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

As the government’s response to the areas in developing countries, they took steps to reform the existing public transportation service system, one of which is by implementing the Trans Metro Deli (TMD) bus system, a revolutionary public transportation system. Intended to improve mobility and reduce congestion, TMD has become a symbol of transformation in urban transportation in Medan. TMD strives to provide reliable, affordable, and efficient public transportation services for Medan residents. The purpose of this study is to analyze the existing conditions of Trans Metro Deli buses and the characteristics of passengers by using questionnaires and descriptive analysis. The research results show that the existing conditions based on the Minimum Service Standards (Standar Pelayanan Minimal PM 27 Tahun 2015) regarding security, safety, and comfort are respectively 66,66%; 56,25%; and 72,72% which means that the existing conditions of the Trans Metro Deli bus have not been complied 100% based on the Minimum Service Standards PM 27 of 20115 (Standar Pelayanan Minimal PM 27 Tahun 2015). The results of the descriptive analysis study for the characteristics of passengers who use the Trans Metro Deli buses, based on gender which is 80% female, resides in Medan is 88%, are aged 15-25 years old is 78%, employment is 82% students, in-family roles as children is 90%, none ownership of vehicle is 49%, income < Rp500.000 is 49%, travel origination of house/boarding house/rent house is 61%, travel destination is 42% school/college, travel frequency 2 times per day is 53%, travel frequency 26-30 times per month is 38%, travel mode from the origin to the bus stop by walking is 37%, travel mode from the bus stop to the destination by walking is 52%, travel distance from the origin to the bus stop > 400 meter is 33%, travel distance from the bus stop to the destination > 400 meter is 37%, 15-30 minutes travel time by Trans Metro Deli bus is 37% , < 15 minutes travel time from the origin to the bus stop is 65%, < 15 minutes travel time from the bus stop to the destination is 33%, travel cost from the origin to the bus stop Rp2000 – 4000 is 45%, and travel cost from the bus stop to the destination Rp2000 – 4000 is 43%.

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

Construction materials testing laboratories play a strategic role in ensuring the quality of infrastructure development. The implementation of ISO/IEC 17025:2017 as a quality management system is a crucial instrument to guarantee technical competence and the validity of test results. However, the effectiveness of this standard's implementation in achieving strategic performance in government laboratories remains underexplored. This study was conducted at the Construction Materials Laboratory Unit (UPTD) of the Department of Public Works and Spatial Planning (PUPR), North Sumatra Province, with the objective of evaluating laboratory performance through the integration of ISO/IEC 17025:2017 and the Balanced Scorecard (BSC) approach. A mixed methods design was employed with purposive sampling involving 60 respondents—30 internal personnel and 30 external service users. Data were collected through questionnaires, structured interviews, and document-based observations. Multiple linear regression analysis of 16 ISO-related variables identified three significant predictors of performance: Traceability Investment (β=0.044), Method Validity (β=0.023), and Management Transparency (β=0.030). Four additional variables with strong beta coefficients derived from interviews and observations were also considered in defining strategic objectives. The BSC-based performance evaluation yielded an overall score of 77.35% ("fairly good"), with the highest contributions from the customer and financial perspectives. The resulting evaluation model offers a practical reference for strengthening accountable and sustainable governance in public laboratories. Future research is recommended to apply this model to government laboratories of varying scale, complexity, and organizational structure in order to assess its external validity and contextual adaptability.
