KAJIAN PERBANDINGAN PENGARUH PENGGUNAAN DINDING PRECAST DENGAN DINDING KONVENSIONAL PADA PROYEK CORDOVA SEMARANG

Abstract

Innovation in the world of construction is something that is indispensable, one of the
innovations in the construction sector is precast. The use of precast is expected to be
able to reduce project costs to accelerate the duration of work. But in fact, the
products of innovation in the world of construction have not been fully able to have
a positive impact, both in terms of cost, quality, time, waste, on project development.
Products of innovation are usually not necessarily in accordance with the wishes
and needs of the customer. The purpose of this research is to analyze the
comparison of products in terms of time, cost, quality, waste, and in terms of K3L
between projects using precast walls and projects using the lightweight brick wall
method. This research was conducted by (1) conducting a project simulation if the
project did not use precast, (2) comparing a real project with a simulation project in
terms of cost, quality, time, waste, and K3L. The use of precast in the Cordova
project when compared to a simulation project that uses lightweight bricks results in
(1) in terms of time saving 36,84 % on the simulation results project (2) in terms of
costs can be reduced by Rp. 101.488.543,99 (3) in terms of quality precast material
has The quality is better than the lightweight bricks (4) in terms of waste, in the
simulation result project it creates more waste (5) in terms of K3L, the use of
precast is more environmentally friendly than the simulation results project.
