Abstract

The rapid population growth in Klungkung Regency, accompanied by an increase in motor vehicle ownership, has accelerated the development of transportation in the region. Although traffic density in Klungkung is lower than that in larger cities, traffic accidents continue to occur. Therefore, identifying accident-prone areas and the contributing factors is essential. This study aims to analyze black sites and black spots, as well as to identify the factors influencing traffic accidents in Klungkung Regency. The research utilizes secondary data obtained from the Klungkung Police Department. The analysis begins with problem identification, data collection, and the application of Z-Score and Accident Equivalent Number (AEK) methods to identify black sites. Black spots are identified using the Upper Control Limit (UCL) method, followed by an analysis of accident-contributing factors. The findings reveal that 79.3% of accidents involve motorcycles, with an estimated economic loss of IDR 646,725,000. The dominant type of accident (44.71%) is loss of vehicle control, while 23% of incidents occur on Sundays, and 32.23% of the offenders are between 16 and 25 years old. Four black sites were identified: Prof. Dr. Ida Bagus Mantra Road, Raya Sampalan Road, Ngurah Rai Road, and Raya Klumbu Tokah Pakeh Road. In addition, six black spots were found: STA 0+000–0+500, STA 2+000–2+500, STA 3+000–3+500, STA 4+000–4+500, STA 5+000–5+500, and STA 7+000–7+500. Contributing human factors include careless behavior, drowsiness, sudden braking, and mobile phone use while driving. Vehicle-related causes involve brake failure, faulty lights, worn tires, and missing mirrors. Accidents are more likely to occur under clear weather conditions due to a reduced perception of risk, which can lead drivers to lower their vigilance and violate traffic regulations. This study offers an integrated analytical approach to identifying black sites and black spots while examining key accident factors. The findings are expected to support targeted strategies and serve as a reference for policymakers and traffic safety authorities in developing more effective prevention measures.

Abstract

Concrete is the most commonly used primary construction material, so increasing demand for raw materials can encourage continuous mining of coarse aggregates, which risks causing natural resource scarcity and environmental damage such as landslides. Thus, alternative materials are needed that are still rarely used but according to applicable standards. Based on this, the author took the initiative to utilize concrete waste as a substitute for coarse aggregate in making new concrete. The concrete waste used comes from ready mix test objects of PT X located in Surabaya, which produces around 8m³ of test object waste that is disposed of every month. The contribution in this study is to reduce concrete waste that pollutes the environment and evaluate whether concrete waste with similar quality can exceed the compressive strength of normal concrete. Therefore, this study aims to analyze the utilization of ready-mix concrete waste stone from PT X located in Surabaya as a substitute material for coarse aggregate in concrete mixtures with a focus on its effect on compressive strength. This study uses a quantitative method through laboratory testing with cylindrical concrete samples with a diameter of 15 cm and a height of 30 cm, totaling 36 samples. These samples will be used for concrete compressive strength tests at the ages of 7, 14, and 28 days. There are two substitution variations, namely 0% and 100%, and two planned qualities, namely Fc 25 MPa for a mixture with K-300 quality concrete waste substitution, and Fc 30 MPa for a mixture with K-400 quality concrete waste substitution. The optimum compressive strength value for the design quality f'c 25 was obtained at 21.26 MPa with 0% coarse aggregate substitution, which is 4.78% higher than 100% coarse aggregate substitution. Meanwhile, for the design quality f'c 30, the optimum value was recorded at 24.59 MPa with 0% coarse aggregate substitution, which is 10.9% higher than 100% coarse aggregate substitution. These results indicate that the compressive strength obtained has not been able to achieve the planned compressive strength target and also the use of concrete waste stone as a substitute for coarse aggregate is highly discouraged.

Abstract

This study was motivated by the high volume of traffic passing through the intersection of Jalan Garuda - Jalan Rajawali - Jalan Raya Betro, which has the potential to cause congestion and reduce the performance of the intersection. The objectives of the study were to analyze the highest number of vehicles crossing the intersection each day, evaluate the performance of the intersection when given a traffic signal (APILL), and determine the appropriate alternative improvements to reduce congestion at that location. The method used is the Pedoman Kapasitas Jalan Indonesia manual (PKJI) 2023 to measure capacity (C), degree of saturation (DJ), delay (T), and queue opportunitie (PA). The results of the analysis show that the highest traffic volume occurred on Thursday, February 20, 2025, at 15:00-16:00 WIB with a total of 2,016 smp/hour, resulting in a capacity (C) of 2,209 smp/hour with a degree of saturation (DJ) of 0.91 and a delay (T) 16 seconds/hour and queue opportunitie (PA) upper limits at 66% and lower limit at 33% so that the level of service (LOS) is in category E, which means unstable motion, stalled vehicles. Then after applying the APILL signal it is estimated that it can increase the capacity (C) 3520 smp/hour, with the degree of saturation (DJ) being 0.75, and the average delay (T) decreasing to 7.52 seconds/hour, and shortening the queue length (PA) to 33 meters so that the level of service (LOS) is in category D. The contribution of this research is to provide valid and data-driven recommendations for intersec

Abstract

Road surface degradation poses significant risks to service quality and traffic safety, necessitating systematic evaluation for effective rehabilitation. This study assessed the condition of the Weleri-Sukorejo road segment using the Pavement Condition Index (PCI) method and safety inspections to formulate targeted rehabilitation strategies. The 12 km road was divided into six segments for visual surveys, with PCI calculations following ASTM D6433 guidelines. Results revealed PCI values ranging from 28 (very poor) to 99 (excellent), averaging 64.5 (fair). Critical findings identified severe damage in segments 0+000–2+000 (PCI 35) and 2+100–4+000 (PCI 28), dominated by potholes (29%) and polished aggregate (24%), requiring immediate structural intervention. Moderate degradation in segments 10+100–12+000 (PCI 64) and 4+100–6+000 (PCI 72) highlighted the need for periodic maintenance, while high-PCI segments (6+100–10+000) warranted routine upkeep. Key contributing factors included overloading, substandard materials, and inadequate drainage. Recommendations prioritize structural rehabilitation, material standardization, and preventive maintenance to enhance road safety and longevity. The study contributes by providing a technical evaluation approach based on PCI data to support more accurate, measurable, and safety-oriented road rehabilitation planning on national road segments.

Abstract

High rainfall and changes in land cover occurring in the Batang Tabir sub-watershed have an impact on surface runoff and increased river flow, triggering flooding and causing road access to be submerged and damage to infrastructure around the river. Therefore, it is necessary to review the flood flow design calculations in the Batang Tabir Sub-Watershed to assess the potential magnitude of flood flows and establish the parameters required for water infrastructure planning. The methods commonly used for flood flow calculations are the Rational Method and the Nakayasu HSS Method. These methods are preferred due to their simplicity, as they only require river data and rainfall data. The selection of an appropriate method for calculating flood discharge must be validated with measured river discharge data. This study aims to determine the design flood discharge method that can be applied to the Batang Tabir Sub-Watershed. This study was conducted by comparing the flood discharge of the Rational and HSS Nakayasu methods with measured flood discharge using frequency distribution based on relevant statistical parameters. The results of the flood discharge calculations using the Rational method for a return period of 2–100 years are closer to the measured flood discharge, with the Rational method yielding a flood discharge of 494.05–1,385. 48 m³/s, the flood discharge using the Nakayasu HSS method for a return period of 2–100 years was 769.32–2,157.41 m³/s, and the measured flood discharge for a return period of 2–100 years was 375.22–1,337.44 m³/s. The validation and evaluation results show that the smallest error value (VE) is found in the Rational method, which is 9%, with the Nash Sutcliffe Efficiency (NSE) value falling into the very good category at 94%. Meanwhile, the Nakayasu HSS method yields the largest error value (VE) at 69%, and the NSE value falls into the unsatisfactory category at 17%. Therefore, the Rational method has a better level of suitability and can be used as a reference in infrastructure planning in the Batang Tabir Sub-Watershed.

Abstract

Rapid development in the construction sector is strongly influenced by its crucial and efficient functions. This drives the construction industry towards better integration. Currently, advances in technology and communication play an important role in overcoming various challenges, one of which is through the implementation of Building Information Modeling (BIM). This approach supports more integrated design and construction processes, resulting in higher efficiency. A primary challenge in construction service provision is the discrepancy in work volume, which can affect project success. By using Autodesk Revit 2025, the implementation of 5D BIM for material Quantity Take-Off can provide higher accuracy in volume estimation. In its implementation, data is processed using Autodesk Revit 2025 BIM software integrated with Microsoft Excel for further analysis. The results show that total volume calculations using Autodesk Revit are more precise compared to conventional methods. The volume of concrete work based on BIM is 2,005.35 m³, which is 83.31 m³ lower than the conventional method at 2,088.66 m³. Meanwhile, the reinforcement volume based on BIM is 354,670.98 kg, which is 29,024.91 kg lower than the conventional method at 383,695.89 kg. The contribution of this research is the demonstration that the implementation of 5D BIM using Autodesk Revit 2025 significantly improves the accuracy of structural work volume calculations compared to conventional methods, thereby helping to reduce volume discrepancies in construction projects and enhancing the reliability of material quantity planning.
