Abstract

In a construction project, there are several aspects that cause the project not to go according to plan. Cost and time are aspects that need to be considered to avoid losses incurred in a project. Jombang-ploso-legundi-gresik road project is one of the road widening projects carried out by PT. Mix Pro Indonesia. The project was carried out with the aim that access to (Surabaya-Mojokerto) or further trans Java toll road is quicker safe and smoother. This research aims to optimize the cost and time on the project using the Earned Value method. Calculations include the calculation of ACWP (Actual Cost of Work Performance), BCWS (Budgeted Cost Work Schedule), and BCWP (Budgeted Cost for Work Performed) using the Earned Value method. From these parameters, estimate aspects of cost and time. As well as project analysis of acceleration on a critical trajectory of work. The results of calculations in the 12th week obtained a BCWS value of Rp 1,216,677,846,400 BCWP = Rp 3,040,372,140,080, ACWP = Rp 3,678,560,000. CV value = -Rp 109,203,495.92, SV = Rp 895,646,816.82, CPI = 0.827, and for SPI = 2,499. From these results it can be seen that the CPI value < 1 which means that there are project expenditures that exceed the original plan. With the results, it can be used as a reference in the implementation of project activities.

Abstract

The science of concrete in the present era has developed. Research on efforts to improve the properties and performance of concrete has been carried out a lot. One of them is modifying a concrete mixture with fly ash as a substitute for some cement and coconut shell charcoal as a substitute for some sand. The chemical properties contained in fly ash are 80% in the form of silica and alumina. The purpose of this study was to determine the slump value and the compressive strength value of the test object added with fly ash with variations of 3%, 6%, 9% of the weight of cement, and 3% baroque coconut charcoal by weight of sand. This research method is experimental, which refers to the Indonesian National Standard with a test object cylinder size 15x30 cm totaling 12 samples tested at the age of 28 days with a quality plan fc'16.60 Mpa. The results showed that the highest slump value was obtained in the test object variation 3, namely 7 cm, while the average compressive strength of each variation has exceeded the quality of the plan with the highest value obtained in variation 2 with a compressive strength value of Fc'24.9 Mpa.

Abstract

Construction management is very necessary in project management. To increase the efficiency and effectiveness of construction development activities, a unit price calculation tool is needed, namely construction cost analysis. Contractors generally make bid prices based on analysis that is not entirely guided by BOW (Burgerlijke Openbare Werken) analysis or SNI (Standart National Indonesia) analysis. Contractors tend to calculate the unit price of work using their own analysis which is based on previous experience in completing a construction work. The purpose of this study was to analyze the unit price of work on the building using the SNI, BOW and Field methods. The work components analyzed in this study are the unit price of materials and wages for partner work and foundation work. In each calculation method used, the most economical cost budget plan is obtained, namely using the field method calculation with the unit price value for the work of a partner, it costs Rp. 509.9996.78 while for foundation work it costs Rp. 722,965.1. By using the field method, a unit price is more economical when compared to BOW and SNI methods. So that these results can be used as a reference in planning the budget for a construction project.

Abstract

The bridge becomes a vital building in living today, which is connecting two areas that separated land. The Golo Bridge also connects the two regions, Blitar and Tulungagung. The Golo Bridge in Tumpakoyot Blitar is part of a national project to build alternative and fast routes in the Southern Java alternative route. The existing Golo bridge is a bridge with a PC-I Girder structure 40 m long and 11 m wide. This research aims tore-plan or modify it to become a bridge with a steel plate girder structure by dividing it into 2 spans, collecting the existing data to be processed in the analysis calculation. It's started with determining the dimensions of the initial structure, giving loads, controlling the structure's ability, also for the abutment & pier. The calculation shows that the dimensions of the steel plate girder have a profile of 2500. 700. 14. 40 mm. Meanwhile, the abutment has a total height of 5.70 m, a width of 4.50 m, and 9.50 m. The bridge pillars have a total height of 6.20 m, a width of 6.20 m and a length of 9.50 m. These results show that the structures is able to support the working loads.
