Abstract

The train flow between Mojokerto - Along the South Cross of Java, which is now only Single Tracking, is a train operation line that is heavy with traffic so that there are often delays in train travel. During the implementation of the Mojokerto-Sepanjang double-track railway construction project in week 43 – week 53, there was a schedule discrepancy in the field work with what had been planned, which could eventually result in time delays and cost overruns for project completion. From the existing background, the problem found is how is the performance of time and cost in the Mojokerto-Along Railway Double Line Construction project (Package 9)? The results of research using the Earned Value method in weeks 43 to 53 are CPI values < 1, this shows that the cost of implementing the work is greater than budgeted, so that the estimated cost of the project to be completed is IDR 53,236,370,349,979, Which means here the project suffers losses in terms of cost. Meanwhile, in terms of time in week 43, the SPI value > 1, meaning that time performance is on schedule or even ahead of plan. While in week 44 to week 53 the SPI value < 1, This means that the project is experiencing delays from the planned schedule. The calculation of the EAS value in week 53 results in the estimated project completion time of 853,993 days or 122 weeks, meaning that the project is delayed from the planned schedule

Abstract

In the Ring Road development project or the Southern Ring Road, located in Torjun District, Sampang Madura Regency, the length of the South Ring Road (JLS) is 6,455 Km, from STA 0+945 to STA 7+400, and the road width is 12m and will be built 5 bridges and flyovers with a maximum height of 10 m. The earthworks that will be discussed are excavation and embankment work, which require a combination of excavators and dump trucks. In this study the calculations use the settlement method in the form of calculations to find out the productivity of using heavy equipment, in the calculation of Excavator Productivity it requires per cycle production data (P), work efficiency and also cycle time as a calculation analysis and for calculating Dump Truck Productivity requires data on the capacity of the dump truck, efficiency factor, hauling distance and also cycle time. Furthermore, to find out how many units of heavy equipment are needed, in the Excavator calculation the data needed is the volume of excavated stockpiles per day and also the length of time for work, and for the calculation of Dump Trucks, the volume of excavation and stockpiles is needed and the calculation of Dump Truck productivity. And then to find out the cost of renting heavy equipment is needed, the data needed for both tools is equipment rental data per hour, length of work and number of units used. Based on the calculations performed, it can be concluded that the productivity calculation for 1 Excavator Unit yields 615,344 m3/day for 7 days, 3 Dump Truck Units yields 566,811 m3/day for 7 days. And for the cost of renting heavy equipment for excavators, the results are Rp. 39,143,371.12, for renting heavy equipment for dump trucks, the results are Rp. 78,638,665
