Abstract

Pembuatan beton yang terus menerus membutuhkan material yang sangat banyak sehingga membuat ketersediaan sumber daya alam menurun, sehingga perlu adanya alternatif bahan pengganti maupun bahan tambah untuk pembuatan beton. Limbah cangkang lokan dapat dijadikan sebagai bahan tambahan dalam pembuatan beton karena cangkang lokan mengandung senyawa CaO yang dapat dijadikan sebagai penguat pada beton. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh penambahan abu cangkang lokan (ACL) sebagai bahan tambah terhadap kuat tekan, kuat lentur dan kuat geser pada beton. Metode yang digunakan pada penelitian ini adalah metode eksperimental. Presentase penambahan ACL yang digunakan pada penelitian ini sebesar 0%, 5%, 10% dan 15%. Berdasarkan hasil pengujian yang diperoleh dapat disimpulkan bahwa penambahan ACL dapat meningkatkan kuat lentur dan kuat geser balok, sedangkan pada hasil pengujian kuat tekan tidak ada peningkatan kekuatan beton. Adapun komposisi maksimum yang diperoleh yaitu pada penamabahan ACL sebesar 5% dan 10%.

Abstract

Concrete making that continues to develop rapidly requires quite a lot of materials, this leads to a decrease in natural resources available for concrete making purposes, so that the search for alternative materials as substitutes and added materials from other natural resources or artificial resources. One of the alternative added ingredients to be used is corn weevil. The purpose of this study was to determine the effect of corn weevil ash on compressive strength, bending strength and shear strength of concrete. The method used is an experimental method in quantitative data. The test objects made totaled 36 pieces with 12 cylinders measuring 15 x 30 cm and 24 blocks measuring 15 x 15 x 53 cm. With the results of the compressive strength test, it decreased along with the increase in the percentage of ABJ 0%, 5%, 10% and 15%, namely 24.08 MPa, 23.21 MPa, 20.22 MPa, 14.70 MPa. For strong bending results, there was an increase in the addition of ABJ 0%, 5% and 15%, namely 1.45 MPa, 1.65 MPa, 1.54 MPa, 1.56 MPa. And in the shear strength test, there was a maximum increase in the addition of a 10% ABJ percentage, which was 20.05 kN and a decrease in the addition of ABJ by 5% and 15%, namely 18.75 kN and 18 kN while for normal concrete it was 19.27 kN.
