ANALISIS PRODUKTIVITAS TENAGA KERJA PADA PEKERJAAN STRUKTUR BETON BERTULANG PROYEK PEMBANGUNAN APARTEMEN KIARA OCEAN PLACE CANGGU

Abstract

Kiara Ocean Place is an apartment or residential development project with complete facilities in a multi[1]story building. During the construction of the structure of this project building, some delays resulted in a time discrepancy with the implementation schedule. Labor productivity is one of the determining factors for the success of a development project in the construction industry. This study aims to find out the average labor productivity, labor wage cost needs per unit of work, and factors that affect productivity that can be used as a tool to determine the success of a project. The result of this study is the average value of labor productivity per day for each work of the reinforced structure, namely the assembly of 100 kgs of column iron of 2076.79 kgs/day, the assembly of 100 kgs of iron beams of 1225.36 kgs/day and the assembly of 100 kgs of plate iron of 1569.48 kgs/day. The installation work of 1 m² of column formwork is 127.20 m²/day, the installation work of 1 m² of beam formwork is 81.63 m²/day and the installation work of 1 m² of beam formwork of plate is 99.62 m²/day. Column casting work of 7.08 m³/hour, beam casting of 4.30 m³/hour, and plate casting of 7.88 m³/hour. The wage cost of assembly labor per 100 kgs of column iron is IDR 37,183.19, assembly per 100 kgs of iron beams is IDR 204,454.75, and assembly per 100 kgs of plate iron is IDR 101,142.57. The installation work of 1 m² of column formwork amounted to IDR 5,042.12, 1 m² of beam formwork amounted to IDR 13,271.77, and 1 m² of plate formwork amounted to IDR 11,953.04. The work of 1 m³ of column casting amounted to IDR 73,937.08, 1 m³ of beam casting amounted to Rp 50,499.00, and 1 m³ of plate casting amounted to IDR 27,248.88. Factors that greatly affect labor productivity in reinforced concrete structure work are the wage level or salary system and the condition of available work tools reducing labor productivity.
