ANALISIS WASTE MATERIAL BESI BETON PADA PEKERJAAN STRUKTUR PROYEK KIARA OCEAN PLACE CANGGU

Abstract

Waste material is defined as material that is no longer used and is generated from construction, repair, or modification processes. A common issue is how to manage waste so that in future projects, the losses caused by waste can be reduced in both percentage and amount. This study will analyze the amount of concrete waste
that occurs in each structural work item of the Kiara Ocean Place Canggu project. The aim of this research is to determine the amount and percentage of waste using the Bar Bending Schedule (BBS) method. The research steps involve calculating material requirements based on as-built drawings, calculating material purchases based on project daily reports, calculating leftover material, determining the quantity of leftover material, calculating the cost of leftover material, calculating the percentage of leftover material cost, and analyzing the research data using descriptive quantitative analysis with the help of Microsoft Excel. The study found that the percentage of waste was 2.77% or 17,501.67 kg out of 631,829.35 kg of steel used in the Kiara Ocean Place Canggu project. The percentage of the leftover material cost relative to the work cost was 0.0003% or Rp 24,502,338 compared to the project value of Rp 81,000,000,000.
