2. Overview References

2.1. Base Theory

The project cost budgeting activity aims to determine the total cost that must be provided by the project owner to realize a building. The total cost includes the provision of materials, payment of wages for workers and the tools used in the construction process. Therefore, the project owner assigns a certain person or business entity called a quantity surveyor (QS) consultant to compile and make an overall cost budget report from the preparation stage to the finishing work. (Manullang, 2013)

According to the National Estimating Society - USA " Estimating of approximating the probable worth or cost, extent, quantity, quality, or character of something based on information available at the time", (Estimating is the art of estimating the possible price or cost, area, quantity, quality). or character of something based on the information available at the time). According to AACE International - USA, " Cost Estimating is the predictive process used quantity, cost and price the resources required by the scope of an investment option, activity or project". resources required for the scope of an investment option, activity or project).

Referring to the definition of estimation and cost estimation as presented above, it can be derived the notion of project cost estimation as an estimate of the possible costs required for project completion based on the information available at the time of making the estimate. (Pastiarsa, 2015)

Actual costing is the process of calculating the volume of work, the prices of various materials, and labor on buildings and projects based on actual data. Planning activities are the basis for making a financial system of a construction program to predict events in a building or project based on actual data. Other things that contribute to costs are:

1. Labor productivity 2. Material availability 3. Availability of tools 4. Weather

5. Contract type 6. Quality 7. Ethics

8. Implementation system 9. Management ability

Budget planning is the process of calculating the volume of work, the prices of various materials and the work involved in a construction. (Ir. Soedrajat S, Analysis (modern method) Advanced Implementation Cost Budget, Bandung, Bandung).

2.2. Analysis Budget Cost Use Book BOW analysis ( Burgerlijke Open Bare werken )

Some people still use guidelines BOW analysis volume 13 as base for determine price profession simple . Many people when this consider contained guidelines in BOW already left behind era . The BOW method is guide for make analysis cost power work traditional . Principle the guide is amount materials needed for every type profession and choice payment for To do profession it . BOW analysis only could used for activity congested creation with use tool traditional like saw and hoe . Tools traditional this still use power man for move tools that . For profession with modern / heavy equipment , BOW analysis is not available same once .

Factor analysis price rare BOW unit used because swelling cost in factor price . in between found principles in BOW method is list wages permanent and material ratio . Both of them analyze price ( cost ) required for count price unit job . Second coefficient produce materials needed and calculation salary . Composition , comparison , and composition ingredient and power work in something profession determined , then price unit ingredient multiplied with price unit local wages that .

by general principle calculation BOW method can concluded as following : Wage Cost = unit price of wages x wage coefficient (BOW) Material Cost = material unit price x material coefficient (BOW) Tool Cost = unit price of wages x tool coefficient (BOW) Price unit work = Cost Wages + Fees Material + Cost Tool

2.3. Budget Analysis of the Minister of PUPR Regulation No. 1 of 2022

New Ministry of PUPR just Secrete Regulation Minister of PUPR No. 1 of 2022, rules this official apply on 2022 .

Principle Regulation Minister of PUPR No. 1 of 2022 is count price unit power work that applies throughout Indonesian territory based on price unit material , price unit wages power work , and price unit tool according to requirements in the field employment . Specification and method work for every type profession customized with use specification standardized technical for profession that . by because that in To do calculation must based on picture technique and plan work as well as applicable requirements ( RKS).

4.5. Calculation of the Difference in Budget Estimates for the BOW Method and the Minister of PUPR Regulation No. 1 of 2022

From the results of calculations using the BOW method and the Minister of Public Works and Public Housing Regulation No. 1 of 2022, the construction work of the Batu City Main Market can be obtained as follows:

1. Estimated cost budget using the BOW method is IDR 102.944.900.000,00

2. The estimated cost budget using the PUPR Ministerial Regulation No. 1 of 2022 is IDR 101.422.600.000,00 From the data above there is a difference in the estimated cost budget between the BOW method and the PUPR Ministerial Regulation No. 1 of 2022 amounting to:

IDR 102.944.900.000,00 - IDR 101.422.600.000,00 = IDR 1.522.300.000,00

The percentage difference between the BOW method and the PUPR Ministerial Regulation No. 1 of 2022 is:

The reason the budget value for the PUPR Ministerial Regulation No. 1 of 2022 is cheaper than the BOW is because the BOW (Burgeslijke Openbare Werken) analysis needs to be revised or improved. The guideline is felt to be no longer relevant because the BOW analysis can only be used if the work is a labor-intensive job using conventional equipment and an unprofessional workforce. While the method of the Minister of Public Works and Public Housing Regulation No. 1 of 2022 has used modern equipment and a professional workforce, so that the cost planning analysis is cheaper and more efficient.

5. Conclusions And Recommendations

5.1. Conclusion

From the calculation results in the discussion of the Final Project on Comparative Analysis of the Budget Plan for the Development of the Batu City Main Market Using the BOW Method and the PUPR Ministerial Regulation No. 1 of 2022, the following conclusions are obtained:

1. The final result of the research shows that the calculation of the cost of building the Batu City Main Market using the BOW method is IDR 102.944.900.000,00, while the results of the cost estimation using the PUPR Ministerial Regulation No. 1 of 2022 are IDR 101.422.600.000,00.

2. From the calculation results, the difference in the estimated cost budget between the BOW method and the PUPR Ministerial Regulation No. 1 of 2022, namely the BOW method is more expensive by IDR 1.522.300.000,00 from the PUPR Ministerial Regulation No. 1 of 2022.

3. Fromthe results of the calculation of the budget plan for the Batu City Main Market development project with both methods, the cost estimation results using the PUPR Ministerial Regulation No. 1 of 2022 are the most economical. Because the index coefficient of the unit price of wages and materials is smaller than the BOW method.

5.2. Suggestion

1. In calculating the unit price of work, more careful calculations should be carried out, especially the selection of the right calculation method so that an economical and accountable budget is obtained.

2. It is recommended that the contractor in preparing the RAB can consider the amount of the difference in bidding costs not much different from the actual costs in the field, because if the bidding costs are reasonable, the competitiveness for the tender will be higher.
