| dc.description.abstract | In a construction project is still too much waste, which do not produce. By implementing
innovations that adopt from the world of manufacturing, which is known as Lean Construction,
at the planning stage in calculating the RAB, it is calculated using the-based RAB application
web , Estimator.id, can make it easier for estimators to calculate the RAB for construction
projects. This study uses data from the Dukuh Maribaya Embung Development Project in
Bumiayu Village, Bumiayu District, Brebes Regency, Central Java in the form of Planning
Images, Unit Price Lists, Unit Price Analysis, Budget Plans, and Implementation Budget Plans.
The data is then calculated using the Estimator.id application. to obtain a comparison of the
RAB from the project documents with a value of IDR 288,160,000,000 and the results on the
Estimator.id application produce a value of IDR 266,610,000,000, indicating a difference of
IDR 21,550,000.00 or 7.47% smaller from the project document while for the RAP, a
comparison of RAP from project documents with a value of Rp.195,170,000.00 and the RAP
calculation results on the Estimator.id application resulted in a value of Rp.189,310,000.00
showing a difference of Rp. project. The results of the application of theConcept Lean
Construction in calculating the RAB and RAP of the dukuh maribaya embung construction
project in the estimator.id application, namely by applying thetechnique Integrated Project
Delivery (IPD) which can realize the principles of IPD. The Estimator.id application can
support theConcept Lean Construction by implementing several Lean Construction Tools to
minimize waste in construction projects. | en_US |
