Abstract

Development of population in Bandar Lampung City and the demand for vehicles from year to year was increasing, such as private vehicles, public transportation, buses and others. This had an impact on the development of facilities and infrastructure of transportation which facilitated the movement occurring on the Zainal Abidin Pagar Alam road section. One of the facilities found on Z.A Pagar Alam road is the Median Opening (U-Turn) which changed direction by turning 180°. One of the effects of the U-Turn movement was going slowly or stopping vehicles. This would affect the movement of other vehicles on the main road. In addition, there were also many cases where the vehicle couldn’t rotate directly because of less radius of rotation. The purpose of this study was to determine the effect of the Median Opening (U-Turn) on the traffic performance at Z.A Pagar Alam road with the Gap Acceptance Method. The use of the Gap Acceptance Method would get the Queue Length value, Gap value and Wait Time (Follow Up Time). Based on the analysis and calculations carried out at the Median Opening (U-Turn) in front of Wisma Bandar Lampung, it could be concluded that the effect of the U-Turn on Monday morning from Tanjung Karang to Rajabasa and vice versa was the biggest effect on traffic performance where the gap was 439 vehicles and queue due to a gap was 899 vehicles, follow-up times was 309 vehicles and queue due to follow-up time was 1449 vehicles. Keywords : U-Turn, Gap Acceptance, Follow Up Time, Vehicle Queue

Abstract

Indonesia has considerable coal reserves, but only a few or even very few can be exploited. The potential of coal owned by South Sumatra Province is known to reach around 85% of the total reserves contained in Sumatra, or around 22.24 billion tons. This means that even though mining is maximized to 50 million tons per year, coal will not be mined for 200 years. To maximize the potential of available coal, modes are needed from the train, but for now there is only one mode used to extract coal from it to transport coal from Tarahan - Tanjung Enim or vice versa. So to maximize the coal's potential, the Ministry of Transportation through the Directorate General of Railways plans to build a double track railway line between Tarahan - Tanjung Enim, one of the roads going through the river is needed a bridge to facilitate the train journey to transport the coal. The railroad bridge that was built was located in KM132 in the burial way of Central Lampung Province. In this bridge construction, the carrying capacity of the foundation needs to be analyzed so that it can withstand the burden of the upper structure and the train.From the results of the study showed that the analysis of the carrying capacity of the permit pile of 1700 kN was greater than the maximum carrying capacity that burdened the pile of 1508.93 kN so that it could be concluded that the structure under the bridge was able to withstand the load from the upper structure. Keywords: analysis, coal, bridge, carrying capacity.

Abstract

The safety level of a slope is influenced by several factors, including factors tilt and loads working on it. Slope conditions with large loads and steep slopes can cause landslides. The influence of heavy rain flushed the majority of the region martapura - baturaja cause landslides and slope at some point in double track train along 50m which have geographic condition consists of the land pile of high steep, so prone to landslides. This is certainly very dangerous for trains, and around the slopes a solution is needed that can be an alternative to make the slope safe from landslide hazards. Based on the laboratory tests that have been carried out of the samples were taken from the site, so the analysis of the existing slopes stability with computer analysis shows the condition of unstable because from the result of numerical safety value analysis 1,731 for condition 1 and 1,732 for condition 2, so that needed reinforcement on the slopes itself. From the analysis of the slopes stability which has been strengthened with a combination of retaining Wall of land and drill pile using the Computer Analysis obtained greater numerical safety value compared by only reinforced with retaining Wall land for 3,978 to condition 1 and 3,983 to condition 2, so the design of strengthening is safe and able to withstand landslide. Keyword : Borehole Data, Geoelectric, Computer Analysis using methods Fellenius

Abstract

Transportation is a very important aspect to stimulate the economy, a region cannot be totally independent in meeting its own regional needs, so that the area needs other regions as a support where one of the connecting infrastructure is a toll road. The Terbanggi Besar - Pematang Panggang Toll Road is one of the 8 Trans Sumatra toll road projects that have entered the construction phase in 2017 which are planned to be operated in 2021. The tariff analysis carried out is based on the Ability to Pay (ATP) and Willigness to Pay (WTP) approach. The average ATP value obtained is Rp 131,638.00 / 100 km and the average WTP value obtained is Rp. 40,989.00 / 100 km. Respondent's ATP value > WTP value indicates that the ability to pay respondents is greater than willingness to pay because users have relatively high income but the utility of these services is relatively low. While the determination of ideal rates is based on the average value of ATP and WTP. Based on calculations, the price of the Terbanggi Besar - Pematang Panggang toll roads tariff is Rp. 86,314.00 / 100 km.
