Abstract

In Operational  Area  8 Surabaya there are several railway lines, one of which is the Wonokromo - Mojokerto line. This lane has a fairly heavy train traffic frequency including the connecting lane south. This will affect the quality of roads on the Wonokromo - Mojokerto line. To assess damage to a railroad seen from several aspects in the structure of the railroad. These aspects are the structure of the railroad, the structure of the railroad and the geometrical structure of the railroad. In Indonesian railways, the railroad uses railroad geometry consisting of several parameters (track gauge, cant, longitudinal level, and lateral level.) as a basis for assessing railroad quality. In this study will analyze the structure of the railroad under the thickness of the ballast to the Track Quality Index (TQI). In this study using a simple linear regression analysis to determine the variation of the thickness of the ballast to TQI. From the results of the analysis conducted, obtained thickness changes that occur in ballast that affect the value of the Track Quality Index (TQI). Where the greater ballast, the greater the value of TQI.

Abstract

Road conditions are vital for smooth land transportation to supporting the economy. Good road management programs, funded by the government through road administrators, are necessary for achieving steady road conditions. The Provincial Government of East Java through the Department of Public Works of Highways has an important role in the process of handling provincial roads. Budget limitations, both Regular APBD funds and special allocation funds and other funds, create a distinct challenge for road administrators in determining an effective and optimal road management program. Based on previous research studies, priority determination of road handling can be carried out using Multi Criteria Analysis. Priority determination criteria used in this study are technical criteria which include: existing traffic conditions, road stability conditions, degree of saturation, travel speed, and travel time; financial and economic criteria which include: Vehicle Operational Costs, Time Value, Benefit Cost Ratio, and Net Present Value. In this study it will be seen based on the results of prioritized maintenance handling found at Link 176 Kediri - Blitar City Boundary for average daily traffic technical criteria has a difference in value of 3,190 cur/hour, with an average road condition of 27.12%, difference in degree of saturation of 0.346, the difference in travel speed is 3.409 km/hour, the difference in travel time is 3.661 minutes and for economic criteria vehicle operational costs has a difference in value of Rp. 8,662,656,168, the difference in the Benefit Cost Ratio is 0.60 and the difference in the Net Present Value is -Rp. 8,382,143,904.

Abstract

Development of ports in the Lamong Bay may result in changes in flow pattern and velocity. In order for such development does not cause a big impact analysis should be made based on the understanding of the physical processes that will occur. This study examined the flow pattern and velocity of Lamong Bay. Existing model simulation results indicate that the direction of motion of the water flow to the front line of Gresik Ports were more integrated with the dominant direction were Northwest - Southeast, whereas in front of the Port of Tanjung Perak flow direction were dominated by West - East. The findings also suggest the direction of movement of currents in the Lamong Bay were more spread and dominated by the movement parallel to the contour of the coastline.
