Abstract

Jammed occurs due to the road infrastructure services level which is smaller than traffic movement needs that available. And the road which potentially to congest is ZA Pagar Alam street. So the government had made a solution to decrease the traffic jam by built an underpass on ZA Pagar Alam street. Furthermore, considering the need for underpass construction aims to reduce jam that occurs, so the writer bring out a research topic that is analyzing traffic flow after the underpass was built and comparing with the traffic flow before the underpass was built. The analysis of this road section performance using the 2014 Indonesian Road Capacity Guidelines method.It is known that the degree of saturation has decreased from 2013 by 1.00. It became 0.655 in 2016 and still dropped in 2019 to 0.63. But, from 2016 to 2019 the decrease was not significant. The speed in 2016 was 42.1 km / hour, and in 2019 was 41 km / hour. From the speed data, the results are not appropriate to RSNI T-14 2004 whereas the speed standard for urban roads should be 50-80 km / hour. So, it can be concluded from the comparison research of before and after the underpass was built, the construction of underpass on the section of ZA Pagar Alam street is not effective to decrease traffic jam.Keywords: Road Section, Degree of Saturation, Underpass

Abstract

The impact of the shadow terminal has caused the congestion and the unrest for road users. This is due to side obstructions caused by pedestrians, buses, cars, and other transportation waiting and picking up passengers around the road, resulting in buildup around the shadow terminal. As a result of the accumulation around the shadow terminal, it caused traffic jams on the Soekarno Hatta - Natar road. In connection with the above problems, it is necessary to study the impact of the shadow terminal on the Soekarno Hatta - Natar road section which can then be compared with the performance of the Soekarno Hatta - Natar road in the absence of a shadow terminal, in order to find out how much traffic performance changes on Soekarno Hatta road - Natar due to the shadow terminal. Thus, this study aims to determine the performance of the Soekarno Hatta - Natar road when there is a shadow terminal and when there is no shadow terminal. The results of this study indicate that there is a change in the value of the side friction in the condition of the shadow terminal on Monday with an event weight of 314 events with a side drag in the absence of a shadow terminal of 213 events. The difference in the value of the side friction will result in a decrease in the value of road capacity, degree of saturation and level of road services. Key words : Road Performance, Side Obstructions, Degree of Saturation, Capacity, Level of Service.

Abstract

The subgrade is a very important role in road construction because it is the beginning of determining the quality and capacity of the soil bearing capacity. One way to strengthen the soil is by soil compaction because it can reduce the amount of unwanted soil subsidence and to rearrange the soil grain structure, so that it becomes denser so that the soil will be denser.This study used grained soil, the type of silty sand from Muara Dua Village, Ulu Belu District, Tanggamus Regency, Lampung Province. The method used is standard compaction and laboratory CBR to determine the impact of the pressure value using a modified press device. The burden used in this research is 3 MPa, 6 MPa, 9 MPa, 12 MPa, and 15 MPa.In the modified press tool test, the values obtained were 12.1 MPa and Laboratory CBR for 3 MPa pressure was 2.7%, 6 MPa pressure was 3%, 9 MPa pressure was 7.8%, 12 MPa pressure was 12.3%, and pressure 15 Mpa of 15.9%. So it can be concluded from the impact of the pressure value using a modified press tool is that the greater the pressure value, the CBR value will increase.Keywords: Standar Proctor, CBR Laboratory, Modification Press Tool.
