Abstract

The Indonesian government stepped up infrastructure projects in the country for logistical and economic equality equalization, infrastructure in the form of a Freeway. This study aimed to analyze and compare the costs, timing, and precise method in Fullslab Precast erection work on 1 module. The data used are primary and secondary. Using the method of removal/erection with heavy equipment cranes. For the calculation of comparative analysis is obtained by analysis of the cost and time analysis. Field observations, and direct cost analysis calculation, and not directly into the calculations that will be loaded to get the proper method to the cost and time of work. The results of the right method are method 1 Crawler Crane at Rp 206.598.086,00.

Abstract

Low geographical conditions and flowed by many rivers and the reduction of retention ponds in Jakarta, then built a reservoir. However, during the implementation period, it was delayed by 9.74%. One of the things that can be done to overcome delays is to choose a method of implementation. The method is diversion and dewatering. The results of the analysis are expected to produce a large comparison of the costs and time of each method. From the analysis results, the cost of implementing the method of soil and rock diversion in the box culvert work is Rp. 363,935,953, while the sandbag diversion method is Rp. 332,805,831. For box culvert work using open pumping dewatering method, the required cost is Rp. 394,637,510. From these data, it was concluded that the difference in the cost of diversion sandbag and rock soil was Rp. 31,130,122. While rock soil and dewatering diversion are Rp. 30,701,557. As well as sandbag diversions with dewatering of Rp. 61,831,679. The results of observations of the implementation time obtained the conclusion that the work of box culvert with sandbag diversion method takes 35 days, and rock soil diversion 49 days while dewatering 63 days. By time comparison the sandbag diversion method is 14 days faster than rock soil diversion, and 28 days compared to the dewatering method. From these data, it can be concluded that in terms of cost and time, the sandbag diversion method is more economical and efficient than the other two methods.

Abstract

Construction projects often suffer from poor performance in terms of execution time management. This is a problem that must be taken seriously. When a delay occurs in a project, there will be additional costs that must be incurred outside the contract and can cause losses for the parties involved, especially the construction contractor. Therefore, it is necessary to pay more attention to the delay in implementation time. The research method used in this research is descriptive quantitative by determining the research variables based on previous journals. Supported by the distribution of phase 1 questionnaires and phase 2 questionnaires which were distributed to 40 respondents related to the Facility Workshop development project located in Melak, East Kalimantan. The questionnaire analysis was assisted by the SPSS version 25 program. The analyzes used were Validity Test, Reality Test, Descriptive Statistical Analysis, Normality Test, Multiple Regression Test, T Test and F Test. From this study, the factors causing delays based on descriptive statistical analysis that meet the requirements of the T-test are material factors (X1), with the indicator "Incorrect material delivery schedule (X1.2)" then supported by the results of multiple linear regression analysis with coefficient positive regression, meaning that there is a significant effect between variables and project delays.
