Abstract

In a construction project either in the planning, implementation and supervision of construction management indispensable good. It is intended that a project can run well, with cost-efficient and can be implemented on time. The method of implementation is an important part in the implementation of a project. What is important is the coefficient of wages as this will greatly affect the welfare of the workers. The determination of the coefficient of wages must be referring to the Indonesian National Standard (SNI). Light brick is a material that is widely used today. However, SNI has not been set on the coefficient of light brick work itself so that the implementation of the field is still used coefficient of wages for work of red brick. Calculating the coefficient of wages is by dividing the daily work volume and number of employees as a factor denominator. From observations made on the installation work light brick building Gereja Kristen Indonesia Bromo, the method used is correct. From the analysis of the data for wage coefficients obtained total wage employment lightweight brick installation methods SNI Rp 76.12 million, while total wages fact the field installation of light brick Rp 63.106 million, and based on research wages brick work lighter by Rp78.955 million, For the cost/m2 installation of lightweight brick according to SNI is Rp 29909.88.

Abstract

ABSTRAK Dalam dunia konstruksi, perkembangan teknologi sangat berperan terhadap sebuah pembangunan. Selain alat penunjang, material juga turut berkembang seiring dengan perkembangan teknologi. Pemilihan material sangat berpengaruh terhadap kualitas dan biaya konstruksi. Untuk analisis harga dalam dunia konstruksi di kenal sebuah istilah yaitu Value Engineering (VE). Value Engineering digunakan untuk mendesain ulang rancangan bangunan untuk penghematan biaya. Hal ini dilakukan untuk kemudian menjadi bahan pertimbangan pemilihan material. Dalam penelitian ini VE dilakukan pada material rangka atap. Penggunaan rangka atap pada penelitian ini adalah rangka atap baja ringan yang kemudian diganti dengan rangka atap Gable Frame. Gable Frame merupakan konstruksi statis tidak tentu. Konstruksi ini bisa diselesaikan dengan cara cross, clapeyron, slope deflection, tabel dan sebagainya. Gaya yang pada batang-batangnya adalah momen, gaya lintang, dan gaya normal. Selain VE yang harus diperhatikan juga adalah metode pelaksanaan dalam pekerjaan rangka atap. Dalam penelitian ini lokasi yang dipilih adalah pembangunan Gedung Fakultas Kesehatan Universitas Tribhuwana Tunggadewi Malang. Dan dari hasil penelitian didapatkan bahwa metode pelaksanaan pekerjaan pemasangan rangka atap baja ringan dan rangka atap gable frame tidak jauh berbeda, hanya saja untuk rangka atap gable frame ditambah item pengecatan dan pengelasan. Dari hasil analisis anggaran diperoleh hasil untuk rangka atap baja ringan Rp 249.760.000 sedangkan menggunakan Gable frame biaya yang dibutuhkan adalah Rp 229.710.000 sehingga penggunaan Gable frame jauh lebih murah atau dengan kata lain penghematan menggunakan gable frame mencapai 10,65%. Kata Kunci : Rangka atap, Value Engineering, Metode pelaksanaan ABSTRACT In the construction world, technological development is very important to a development.
