Abstract

Plastik banyak digunakan dalam keperluan sehari hari sehingga banyak limbah plastik yang dihasilkan. Diperlukan penanganan yang tepat dalam menangani permasalahan limbah plastik. Plastik tipe Acrylonitrile Butadiene Styrene (ABS) merupakan salah satu jenis plastik yang dapat didaur ulang. Pada kajian ini, plastik ABS digunakan sebagai material pengganti agregat kasar karena memiliki sifat yang kuat dan ringan. Tujuan penelitian ini adalah untuk mengetahui perubahan kuat tekan dan berat jenis terhadap persentase plastik. Persentase substitusi yang digunakan adalah 40%, 55%, 70%, 85%, 100% terhadap volume absolut agregat kasar. Pengujian kuat tekan dan berat jenis menggunakan silinder diameter 10 cm dan tinggi 20 cm. Uji kuat tekan dan berat jenis dilakukan pada beton dengan umur 7, 14, 28 hari. Berdasarkan pengujian yang dilakukan, kuat tekan dan berat jenis yang didapatkan mengalami penurunan terhadap beton tanpa substitusi biji plastik ABS. Penurunan kuat tekan rata rata pada umur 28 hari terhadap beton tanpa campuran plastik (40.009 MPa) yaitu secara berurutan sebesar 17.34% (33.070 MPa), 19.34% (32.272 MPa), 25.83% (29.675 MPa), 27.42% (29.038 MPa), 27.60% (28.966 MPa). Sedangkan penurunan berat jenis rata rata pada umur 28 hari terhadap beton tanpa campuran plastik (2265.942 Kg/m³) yaitu secara berurutan sebesar 5.32% (2265.942 Kg/m³), 8.74% (2067.953 Kg/m³), 10.58% (2026.149 Kg/m³), 17.18% (1876.755 Kg/m³), 19.88% (1815.427 Kg/m³). Beton ringan menggunakan agregat biji plastik ABS dihasilkan pada proporsi substitusi 100%. Plastics are widely used in daily needs so that a lot of plastic waste is produced. Proper handling is required in dealing with the problem of plastic waste. Acrylonitrile Butadiene Styrene (ABS) plastic is a type of plastic that can be recycled. In this research, ABS plastic is used as a substitute for coarse aggregate because it has strong and light properties. The purpose of this study was to determine the changes in compressive strength and specific gravity to the percentage of plastic. The substitution percentages used are 40%, 55%, 70%, 85%, 100% of the absolute volume of coarse aggregate. Testing the compressive strength and density using a cylinder with a diameter of 10 cm and 20 cm high. Compressive strength and density tests were carried out on concrete with an age of 7, 14, 28 days. Based on the tests carried out, the compressive strength and specific gravity obtained have decreased to the concrete without the substitution of ABS plastic pellets. Decreased compressive strength of average at 28 days against the concrete without plastic mixture (40.009 MPa) are sequentially 17.34% (33.070 MPa), 19.34% (32.272 MPa), 25.83% (29.675 MPa), 27.42% (29.038 MPa), 27.60 % (28.966 MPa). While weight kind of average at 28 days against the concrete without plastic mixture (2265.942 Kg / m³) are sequentially 5.32% (2265.942 Kg / m³), 8.74% (2067.953 Kg / m³), 10.58% (2026.149 Kg /m³), 17.18% (1876.755 Kg / m³), 19.88% (1815.427 Kg / m³). Lightweight concrete using ABS plastic pellet aggregate is produced at a substitution proportion of 100%.
