Abstract

Effective road management is crucial to ensure the smoothness and safety of the transportation system in Pesawaran Regency. Although various strategies have been implemented to determine road maintenance priorities, challenges remain in fully integrating technical and non-technical elements comprehensively. This study aims to address these shortcomings by comparing two analytical methods, namely the Fuzzy Analytic Hierarchy Process (FAHP) and the Provincial/District Road Management System (PKRMS), and by developing a combined approach expected to yield more accurate and comprehensive priority determinations in road infrastructure management. The research methodology employs both qualitative and quantitative approaches. FAHP is utilised to address uncertainty and subjectivity in decision-making, while PKRMS provides evaluations based on technical data. Analysis results indicate significant differences in road maintenance priorities generated by the two methods. FAHP ranks the Negeri Sakti - Batas Lampung Selatan (177) road segment as the highest priority with a weight of 0.241 whereas PKRMS prioritises the Negara Saka - Krisnowidodo (081) road segment with a TPI value of 76.040. The integration of these two methods produces a more comprehensive priority ranking, with the Lumbi Rejo - Tresno Maju (089) road segment emerging as the top priority with a TPI value of 132.337. This research introduces an integrative approach that combines FAHP and PKRMS, offering a novel solution for determining road maintenance priorities that simultaneously consider both technical and non-technical aspects.

Abstract

the increasing number of passengers and the planned development of urban transportation infrastructure. However, the selection of station locations is a crucial aspect that requires careful consideration. This study aimed to identify the key criteria for determining passenger rail station locations in the city. The Delphi method and Analytic Hierarchy Process (AHP) were used to obtain structured expert assessments and to measure the priority of location criteria. The results indicated that accessibility was the criterion with the highest weight (0.480), followed by central activity areas (0.204), land use (0.167), and demand (0.148). Furthermore, the most influential sub-criteria were road networks (0.228), public transportation networks (0.156), and proximity to commercial and service centers (0.097). These results suggest that accessibility and proximity to central activity areas should be the primary considerations to improve mobility, reduce regional disparities, and support sustainable economic growth.

Abstract

Tanah lempung dengan plastisitas tinggi, kohesifitas yang besar berakibat fluktuasi kembang susut yang relatif besar. Hal ini yang menyebabkan kondisi jalan yang dibangun diatas tanah lempung mengalami kerusakan. Oleh karena itu dalam penelitian ini dilakukan perbaikan tanah dengan cara memperbaiki gradasinya yaitu mencampur tanah asli dengan pasir. Sampel tanah yang digunakan pada penelitian ini berasal dari Ruas Jalan R.A.Basyid, Kecamatan Jati Agung, Lampung Selatan pada STA 3+100 dengan variasi pasir 0%, 5%, 10% dan 15 % dari berat tanah. Pengujian pada penelitian ini adalah pengujian CBR dari efek pegembangan tanah, lalu dilakukan perhitungan tebal perkerasan dengan metode analisa komponen SKBI 2.3.26.1987 dan metode manual desain perkerasan jalan 2017. Pada penelitian inisampel tanah yang digunakan termasuk kelompok A-7-6(tanah yang buruk). Setelah penambahan variasi pasir, batas plastis tanah tersebut meningkat sedangkan batas cair dan indeks plastisitas menurun, hal ini mengakibatkan pengembangan tanah terjadi penurunan pada 15% pasir yaitu dari 0,62% menjadi 0,17%, sedangkan nilai CBR mengalami peningkatan yang signifikan pada pasir 15% yaitu dari 2,6% menjadi 26,0%. Dengan hal ini pada perhitungan dengan metode analisis komponen SKBI 2.3.26.1987 tebal lapis menjadi lebih tipis, pada 0% pasir yaitu tebal D1=7,5 cm, D2=25 cm dan D3=44 cm, sedangkan pada 15% pasir tebal D1=5 cm, D2=17 cm dan D3 tidak digunakan. Perhitungan dengan menggunakan metode manual desain perkerasan jalan 2017 pada variasi pasir 5%, 10%, dan 15% tidak perlu perbaikan jalan karena nilai CBR ≥6.

Abstract

 The existence of roads is a tool to serve the movement of activities in urban areas. The problems that occur on the Jl. Imam Bonjol and Jl. RA Kartini is the number of vehicles that carry out activities in and out on the left and right of the road, the slow flow of vehicles, pedestrians, and the number of people who make buying and selling transactions on the right and left sides of the road which causes congestion and queues of vehicles that result in the road section is not functioning properly, namely as the main road in the city of Bandar Lampung. For this reason, it is necessary to analyze the effect of side barriers on the capacity of these roads.The purpose of this study is to identify the effect of side barriers on road capacity, the volume of vehicles on Imam Bonjol and RA Kartini roads and the difference in travel time required on the Imam Bonjol and RA Kartini roads in the morning and evening. To achieve a goal, the target is What is done is expected to be able to help the proper handling of road performance improvement and to determine the magnitude of the influence of side friction factors on the capacity of roads that occur in urban areas, especially Imam Bonjol and RA Kartini roads. And the method used in this study usesGuidelines for Indonesia's Road Capacity (PKJI) 2014.The output obtained from the research is the very high effect of side friction (ST) on the Imam Bonjol and RA Kartini roads resulting in a decrease in capacity, namely the Imam Bonjol road has decreased capacity by 27.73% and the RA Kartini section has decreased capacity. amounted to 26.27%. From the results of the survey conducted, it was found that the volume of heavy traffic affected the value of the capacity on the roads of Imam Bonjol and RA Kartini along 200 meters respectively.It was found that the effect of very high side friction (ST) resulted in an increase in travel time, namely on roads.

Abstract

An urban area that has a function as a center of activity in an area certainly affects the high levelof community activity and indirectly causes a high number of movement of people, vehicles andgoods in urban areas.The ability to accommodate traffic flows depends on the physical conditionof a road, both in quality and quantity as well as on the operational characteristics of thetraffic.The purpose of this study is to analyze road characteristics and to determine therelationship between volume, speed and density on the Zainal Abidin Pagar Alam road and theImam Bonjol road in Bandar Lampung. This study uses the Greenshield and Greenberg modelsas a method. This method results that the relationship between velocity and density is linear sothat we can see how the pattern of the relationship between velocity, density and volume is. Theresults of this study obtained the free flow speed for Jalan ZA Pagar Alam for 55 km / hour andfor Jalan Imam Bonjol is 38 km / hour. The actual speed on Jalan ZA Pagar Alam is 28km / hourand on Jalan Imam Bonjol is 30km / hour. Meanwhile, the congestion density found on the ZAPagar Alam road is 931 cur / hour and on Jalan Imam Bonjol is 979 cur / hour. The mostoptimum model is in the Greenberg model for Jalan ZA Pagar Alam because the Greenbergmodel has a determination coefficient value (R2) which is closer to the highest accuracy of 0.98%and the Greenshield model on Jalan Imam Bonjol is because it has a determination coefficientvalue ( R2) which is closer to the highest accuracy of 0.96%.

Abstract

AbstractSide friction are side-road activities that have a significant effect. The high level of roadside activity affects the capacity and performance of roads in an urban area, with the cause of the growing and developing population activity every year. This study uses a method that is guided by the Guidelines for Indonesia's Road Capacity (PKJI 2014).  In this study, the value of side friction on Teuku Umar's road (Advent Hospital – Koga Market) was 567 skr / hour (medium class), while on Imam Bonjol's road (Langkapura) it was 158skr / hour (low class). For the Teuku Umar's road there was a decrease in capacity by 4%, while on the Imam Bonjol's road there was a decrease in capacity by 1%. The cause of congestion on Teuku Umar's road is due to vehicles turning around and vehicles coming in and out of the road, while on Imam Bonjol's road it is due to vehicles going in and out of the road. So that the alternative solution to overcome traffic jams on Teuku Umar's road (Koga market - RS Advent) is to curb motorists who stop carelessly on the road, and set the traffic signs that prohibited from stopping on each side of the road, while on Imam Bonjol's road (langkapura– kemiling) it is necessary to monitor vehicles entering / exiting the alley, because it has the potential to cause long traffic jams. Keywords : Side friction, Guidelines for Indonesia's Road Capacity, Traffic.
