ANALISIS PERBANDINGAN METODE PEKERJAAN PLESTERAN MENGGUNAKAN SEMEN PASIR DENGAN MORTAR INSTAN TERHADAP WAKTU DAN BIAYA (STUDI KASUS : PROYEK RUMAH SAKIT LIRA MEDIKA)

Abstract

A construction project is a series of activities in building facilities and infrastructure. Project execution requires a measurement of productivity that serves as a parameter for project success. The purpose of the study was to compare the average productivity of cement, sand, and instant mortar and compare the cost and time of the two stuccoes. The method used is comparative descriptive with data collection through observation and field surveys. The research shows that the productivity of cement sand in normal time is 10,640 m2/day, and the productivity of instant mortar plastering in normal time is 15,841 m2/day. The price of a cement sand stucco unit is Rp 82,630.31, if overtime is Rp 52,672.71, instant mortar stucco is Rp 95,579.86. The difference in the total cost of sand cement stucco analysis for AHSP Badung 2023 if applied to a wall covering an area of 6,025.91 m2 is IDR 20,760,194.67 or 3.20%. The total price difference of instant mortar stucco analysis for AHSP Badung 2023 is IDR 117,676,917.54 or 9.27%. The study shows that applying sand cement stucco in normal time can be completed in 113.269 days if overtime can be completed in 83.516 days while instant mortar plastering can be completed in 76.079 days. The time difference between the two stuccos is 37.190 days
