Abstract

Bangunan gedung memiliki berbagai unsur seperti tanah dasar, pondasi, sloof, balok, kolom, dinding, lantai, dan atap. Dalam proses pekerjaan unsur – unsur bangunan gedung dibutuhkan, Rencana Anggaran Biaya (RAB), Material, draft gambar, dan Sumber Daya Manusia (SDM). Material, merupakan salah satu komponen penting dalam proyek kontruksi. Berhasil atau tidaknya suatu proyek konstruksi bangunan gedung, salah satunya ditentukan oleh kualitas pengelolaan material dalam menunjang keberhasilan suatu proyek. Lokasi penelitian berada pada Pembangunan Gudang Penyimpanan Limbah Sementara PT. Ansori jaya. Penelitian dilakukan dengan cara menganalisa RAB, Analisa Harga Satuan Pekerjaan, Laporan Pembelian Material. Berdasarkan penelitian, material bekisting kayu kelas III yang dibeli oleh pihak kontraktor sebanyak 46,71 m3 dan yang digunakan sebanyak 18,18 m3. Kayu kelas II yang dibeli oleh pihak kontraktor sebanyak 15, 23 m3 dan yang digunakan sebanyak 7,32 m3. Untuk Plywood pihak kontraktor membeli sebanyak 830 lbr dan yang digunakan sebanyak 160 lbr. Sedangkan untuk kayu galam pihak kontraktor membeli sebanyak 608 btg dan digunakan seluruhnya. Semua material yang digunakan untuk pekerjaan plat lantai dan balok lantai 2.

Abstract

Indonesia is a country with a high earthquake rate, that's because Indonesia is geographically located. So that in the development of the construction world, materials are needed that can minimize damage due to earthquakes. One indicator of a material that is able to withstand earthquake forces is its light weight but is able to withstand earthquake forces. The existence of styrofoam as waste can be used as an additional material for making materials because it has a light weight. Styrofoam is a material that is not easily decomposed by nature and the manufacture of styrofoam as a hazardous waste is the 5th largest in the world. The purpose of the study was to determine the compressive strength of concrete bricks with the addition of styrofoam. This study added styrofoam waste as a substitute for fine aggregate with a percentage of 0%, 20%, 40% and 60%. The test object was made the size of a brick, namely 23cm x 11cm x 5cm. The results of the study show that the greater the addition of styrofoam as a substitute for fine aggregate, the weight of the concrete brick is reduced and the greater the percentage of the addition of styrofoam causes the compressive strength of the concrete brick to decrease for a percentage of 60% of the concrete brick entering class 100 requirements based on SNI 15-2094-2000 with a minimum average strength of 100 kg/cm2. Keywords: Concrete Brick, Styrofoam, Compressive Strength
