Abstract

The increase in the number of vehicles is not in line with the increase in transportation infrastructure. The construction of flyovers is one of the measures to provide transportation infrastructure that helps to enhance thehighway capacity. However, there are several things that need to be considered of the construction of flyover. In addition to reducing traffic density, it is also necessary to pay attention to the new routes that will be chosen to be the solution to the existing traffic congestion. The research objective is to analyze the performance of the section of Jl. Indra Bangsawan in its existing condition and provides alternative solutions so that  it is more optimal. 1997 Indonesian Road Capacity is used to analyze the performance of this intersection.Based on the results of research, it is known that the existing conditions of each segment are saturated (DS> 0.70), namely in the first segment of 1.16, Segment II of 1.37 and Segment III of 1.24, with the highest density in segment II. To improve the performance of the section, several alternative improvements were made with widening road dimensions, applying one-way systems, closing lanes and controlling side barriers. From these alternatives an effective repair solution is the application of a one-way system and control of side barriers.Keywords: Degree of Saturation, Capacity, Density, Roads

Abstract

Congestion has become a common problem faced by the community. The intersection of Pramuka -Cik Ditiro street is one of the most prone congestion areas in Bandar Lampung. One of the solution that can we do to reduce congestion is to build a fly over,that is expected to reduce congestion so that it will give a good impacts. The purpose of this study is to determine traffic conflicts and the magnitude of travel delays occurring around the Kemiling fly over. This study uses gap acceptance and follow-up methods to calculate the queue of vehicles that rotate at u-turn. The data collection is done by recording a video. The duration of the recording are 4 times with a duration of 1.5 hours in the morning and evening for 2 days (Monday and Saturday). Based on data analysis that has been carried out, after the construction of a fly over, it turns out there are still some congestion conflicts at several points during rush hour (morning and evening). The data obtained is the delay on the u-turn in front of the fly over which is 8.42 seconds for the average gap time and 5.13 seconds for the average follow-up time with the number of vehicles passing as many as 274. Therefore to solving the problem a roundabout being planned with a diameter of 20 m. Keywords: Fly Over, U-Turn, Follow-Up, Gap Acceptance, Roundabout.

Abstract

In the field of highway damage to road pavement in addition to weather factors and overloading can also occur due to poor subgrade. A good alternative so that the soil on the highway subgrade does not experience excessive swelling is to use cement additives.Soil samples were tested using subgrade soil material originating from the RA. Basyid passageway of Fajar Baru Village, Jati Agung Subdistrict, South Lampung at STA 3 + 900 and variations of cement used were 0, 4, 8 and 12%. The test carried out is by testing the swelling of soil against CBR which has been marred for 3 days, then based on the results of the test, the calculation of pavement thickness was carried out by the method of analysis of components of SKBI 2.3.26.1987.In testing physical properties, the soil includes the classification of A-6 soil or poorly categorized soil types. However, after adding variations in soil classification cement into a good A-2-4 category. In the CBR swelling test on 0% cement percentage swelling values were 0.62% and CBR 0.9%, in the 4% percentage swelling value 0.27% and CBR 42.6%, at the percentage of 8% swelling value 0.19% and CBR 53.2%, and 12% percentage swelling value 0.06% and CBR 78.1%. From the calculation of the pavement thickness, the greater the CBR value, the thicker the thickness of each layer.Keywords: CBR, Soil Swelling, Pavement Thickness, Stabilization, Cement

Abstract

Improving the Infrastructure development needs the soil that capable to support the load. It because soil is a material that major the role to support every construction. To identify a good soil is by doing physical and mechanical soil test. Soil compaction is process of increasing the soil density by reducing the particles proximity so it can reduce the air volume. Soil type is influencing to the maximum dry volume weight and optimum water content of that soil. Based on the soil type, compaction is divided into four types. In this research is using two types of compactions that are type A and Type C with purpose to find out the effect of soil particles diameter by passing sieve analysis to soil compaction using standard method.Compaction is done based on blow method and pressure method. In pressure method is using modification compaction tool with 5 Mpa, 10 Mpa, and 15 Mpa pressures.The result of this research is the blow method compaction type A has a higher water content than type C, but the value of maximum dry volume weight Type C higher than type A.  In pressure method it can be concluded that as the higher pressure so the water content and the maximum dry volume weight are also getting higher.Keyword:Soil Particles, Standard Method of Compaction, Blow Method and Pressure Method Compaction

Abstract

High Speed Rail (HSR) is currently regarded as one of the most significant tecnological breakthrought in passenger transportation. Compare to a convensional train, a high speed train will shorten time travel. This study aims to evaluate the viability of high speed rail project based on financial analysis. The parameter used to analyse the financial viability are NPV, BCR, IRR, PP and Break Even Traffic Volume. The analyses also includes sensitivity analysis with a variety of discount rate, annual income and investment cost value. The result of financial viability analysis shows that the project does not meet the financial requirements. It is indicated by negative NPV value, IRR value of 0,27 to 2,28 smaller than the discount rate and PP value much longer than the concession period which are of 50 years. The result of Break Even Traffic Volume shows that the range of total demand number to reach NPV=0 are between 11,27 millions to 11,58 millions. The Number  is very much greater than total passenger number of Argo Parahiyangan train in the year 2018 that is 4,38 millions/ year. Even though based on the financial viability analysis the High speed rail Jakarta-Bandung project is not be feasible. However, based on the economic and social benefits the project is crucial to solve traffic congestion, reduce the pollution rate, and save the time travel.Keywords :High-Speed Train, financial analysis, financial feasibility parameters
