Box Girder Construction on Toll Road Project 2 use Manual Program Evaluation and Review 3 Technique (M-PERT) and Value Engineering (VE) to 4 Performance Cost and Time Improvement

: Indonesia's ranking is 72 out of 141 countries and is in 5th place in the group of countries 12 in Southeast Asia based on the 2019 Global Competitiveness Index (GCI) by the World Economic 13 Forum. The current development of infrastructure development is not directly proportional to an 14 increase in the number of infrastructure users by 1.9% from an annual increase of 10%-55%. And 15 the occurrence of implementation time experienced a delay of 11.95%. And with a low rate of 16 return on books with high investment costs in the construction of 7.79%. The expected goal in this 17 research is to have cost and time efficiency in implementing infrastructure development. In this 18 study, the focus is on the upper structure work, one of which is the box girder, to improve time and 19 cost efficiency based on the Manual Program Evaluation and Review Technique (M-PERT) and 20 Value Engineering (VE) in the case study of this research. The case study using the M-PERT 21 method resulted in a time efficiency value of 98.87% of the completion time at the job site, while the 22 VE method obtained an added value of income outside toll roads of 9.38% of construction costs.

Infrastructure development is the main target of government programs, as evidenced directly 26 by making infrastructure development one of the main strategic issues and targets or a general 27 infrastructure target that must be worked on. This development is the main target because   Based on the data that has been collected from questionnaires distributed to respondents as 122 described in the previous section, tabulation of the data was carried out to facilitate the analysis 123 process. Data tabulation is intended for entering data from certain tables and arranging the numbers 124 and calculating them. There are two types of tables that are often used, namely data tables and work 125 tables. Data tables are tables that are used to describe data, making it easier for researchers to 126 understand the structure of the data. While the worktable is a table used to analyze the data 127 contained in the data table.

In this study, the method used in this study was the Manual Program Evaluation and Review

Technique (M-PERT) method. In determining the success of a project, the stage of quality 139 maintenance to remain at a predetermined standard, there needs to be supervision and emphasis on 140 the sustainability of a construction project. These stages include: The planning stage needs a quality planning procedure (quality planning)

142
 The implementation phase needs quality assurance (quality assurance)

143
 The evaluation stage needs control of quality (quality control),

144
 Maintenance stage and quality development (quality Improvement)

145
Emphasis on these four stages has been carried out on any construction project with the 146 assumption that the better the quality, the higher the level of customer satisfaction (customers), and 147 the return (major returns) to the capital invested in the project will be higher.      The following are the stages of work items from the beginning to the end of the activities for 264 foundation work and the following toll road construction structure works.

The goal of this research is to acquire any work items that are viable to be value-engineered [20].

302
In some countries, it is 50% -50% this kind of practice encourages contractors to implement VE 303 during construction. The goal of this research is to acquire any work items that are viable to be 304 value-engineering [21].   Led 12 Based on Figure 9 and Table 3, from each additional function work, the development value or 355 initial cost for each addition is obtained. From the calculation of the development financial analysis 356 of the addition of functions, the NPV value, IRR value, and BCR value are obtained, as follows:
