Abstract

In the 2016-2021, there were 12 accidents with 22 deaths and 107 injuries on the Pemalang – Purbalingga road section. One of the factors causing accidents is the lack of attention to infrastructure that meets safety aspects. Even though the number of accidents caused by infrastructure is relatively small when compared to the human error (human) and vehicle (facility) factors, serious attention must still be paid. Traffic accidents caused by a lack of road infrastructure are generally caused by an inaccurate road geometric design, poor road surface conditions, lack of visibility and so on. Therefore the research aims to find accident-prone locations, the causes of accidents from the standard values of road technical requirements and accident regression models. The results of this study. Segments that are categorized as accident-prone locations are STA 32+000, 34+000, 36+000, 47+000 and 48+000. Substandard grades will be the cause of traffic accidents based on road technical requirements. The regression model that can be used to predict the number of accidents on provincial roads according to the variables examined in this study is: Y = -2.618 + 0.049 Grade – 0.019 X Slope – 0.008 H Curv – 0.417 V Curv + 0.264 road width + 0.081 condition IRI roads + 0.014 PCI Road Conditions

Abstract

In line with population growth, Pangkalan Bun City has now expanded to include linear pathways or the surrounding area, not only in the city center. This has resulted in the City of Pangkalan Bun having many large trading centers and one of them is the construction of the Abdul Rasyid Tower on Jalan Udan Said in front of the CBI Group head office, Pangkalan Bun, West Kotawaringin Regency, which will result in congestion / attraction of new trips in Pangkalan Bun City. Data collection was carried out by means of a direct survey at the Abdul Rasyid Tower intersection on Jalan Udan Said during peak hours in the morning, afternoon and evening from 06.00 – 18.00 WIB. From the survey results, grouping was carried out on each segment at the intersection and presented in the form of a vehicle table. In calculating the savings analysis using the 1997 Indonesian Highway Capacity Manual and Vissim Software. Traffic performance around the Abdul Rasyid Tower project site at the time prior to construction according to MKJI 1997 calculations, the biggest delay at the afternoon intersection at the first intersection was 7,45 second. The results of the Vissim Software the biggest intersection delay occurred in the morning at the first intersection, which was 7,98 second. Traffic performance around the Abdul Rasyid Tower project site during construction according to MKJI 1997 calculations, the largest intersection delay occurred in the afternoon at the first intersection of 9,47 second. The results of the Vissim Software, the biggest delay at the intersection occurred in the afternoon at the first intersection at 9,89 second. Traffic performance around the Abdul Rasyid Tower project site during post-construction according to MKJI 1997 calculations, the largest intersection delay during the day at the first intersection was 7,78 second. The results of the Vissim Software, the largest delay at the first intersection during the day is 8,21 second.

Abstract

The road that often has accidents on the uphill and downhill sections as well as sharp bends is the Prof. Dr. Ir. Sutami Road Section. This path is used by different types of vehicles, from small cars to heavy trucks making their way to the industrial area. In STA 0+000 to STA 1+200, accidents often occur because it has an uphill road contour with grades varying between 0.15% -12.61%. Referring to traffic accident data from 2015 to 2019, there have been occurrences leading to minor harm, major harm, and loss of life. For this reason, researchers need to analyze the causes of accidents, analyze road alignment, analyze how to overcome and prevent them. The approach employed involves collecting primary and secondary data, then evaluated together. The evaluation data show that the origins accident include human factors, where individuals panic when the brakes fail, vehicle factors related to operational unfitness, and road factors as the location is on a collector road with a VLHR of 13,000/SMP per day. With the presentation of trucks, 47% have a topography with a height difference of up to 39 meters at a distance of 695 meters. The results of the alignment analysis with a slope of almost 13% the slope value varies from 6% - 12% per 25 m and LOS C. How to overcome and prevent accidents are carried out safety driver training, operational vehicle regulations and. Improvement of road alignment with climbing lanes and rescue paths.

Abstract

Development in the Mandalika Special Economic Zone (KEK) has several work packages, one of which is Package 1 which during the implementation process there were several obstacles that had a major impact on the postponement of the planned construction schedule for the project running from June 15, 2024 to June 10, 2023, postponed to September 30, 2023. The PERT method itself is to find out the time needed for the construction of package 1. The result is that there is a difference in the time needed to complete the MUTIP Package 1 project. For the Baseline for the completion time of the MUTIP package 1 work, it is known that the planned completion time is 831 days or starting from June 15, 2021 to June 10, 2023 (accuracy 86.62%). Meanwhile, the completion time of the work after being calculated using the PERT method requires a completion time of 831 days starting from June 15, 2021 to September 24, 2023 (accuracy 99.28%). and the acceleration carried out using the Fast Track method is known to require 724 days. So it can be concluded that the calculation of time using the PERT method and acceleration using the Fast Track method is more effective when used for the conditions that occur in the MUTIP Package 1 development project at the Mandalika Special Economic Zone.

Abstract

In recent years, the development of road infrastructure in Indonesia has shown quite rapid progress. However, this process often faces technical obstacles, especially those related to the condition of the subgrade which has low bearing capacity. This type of soil condition requires a stabilization process so that the California Bearing Ratio (CBR) value of the soil can increase so that it meets the strength standards required to support durable road construction. In relation to efforts to improve the characteristics of soft clay soil in the Semarang area, a study utilized coal combustion waste in the form of fly ash and bottom ash from the Tanjung Jati B Steam Power Plant (PLTU). This alternative material is used to improve the quality of the soil so that it is more technically feasible for various construction needs. Through a series of laboratory tests with variations in the composition of the fly ash mixture between 15% to 45% and bottom ash between 15% to 25%, a significant increase in the CBR value was obtained compared to the original soil without treatment. The best composition obtained in this study consisted of 40% soil, 45% fly ash, and 15% bottom ash, with a CBR value reaching 8.95%. These findings indicate that coal combustion waste has great potential in improving the quality of the subgrade. The use of this material can be a cost-efficient and environmentally friendly alternative in the construction of road infrastructure
