Analisis Perbandingan Efisiensi Harga Dan Waktu Dalam Pembangunan Laboratorium Sd Dengan Menggunakan Tiga Bahan Batu Bata, Batako Dan Hebel

Abstract

Walls are essential elements in building structures because they function as space dividers while also contributing to the overall strength and comfort of the building. The selection of wall materials remains an important issue since each type of material has different characteristics, costs, and construction durations. This study was conducted to determine the comparison of costs and construction time for wall installation using clay bricks, concrete blocks, and lightweight concrete blocks in the construction of the Laboratory of SD Negeri 200510. These three materials were chosen because they are widely used in building construction and have significant differences in composition and installation processes. The purpose of this research is to provide a clear overview of cost efficiency and construction duration to assist decision makers in selecting the most suitable wall material. The results show that the installation cost of clay brick walls is Rp 51,045,839.3, the cost of concrete block walls is Rp 74,158,864.7, and the cost of lightweight concrete block walls is Rp 85,710,639.7. In terms of construction time, clay brick walls require 24 days, concrete block walls require 26 days, and lightweight concrete block walls require 71 days, with the same number of workers involved, which is three people per day. These findings indicate that clay bricks are the material with the lowest cost and the shortest installation time, while lightweight concrete blocks take the longest to install. The results are expected to serve as a reference in determining efficient wall materials for construction projects.
