Abstract

Self Compacting Concrete (SCC) merupakan beton yang mampu memadat sendiri. Dalam penelitian ini menggunakan limbah padat B3 (Bahan Berbahaya dan Beracun) yang berasal dari RSUD Dr. Soetomo Surabaya sebagai bahan tambahan pengganti semen. Abu insinerator dilakukan pengujian Scanning Electrone Microscope (SEM), X-Ray Diffraction (XRD), X-ray Fluorescence (XRF), Particle Size Analysis (PSA) dan pengujian Toxicity Characteristic Leaching Procedure (TCLP). Pengujian Toxicity Characteristic Leaching Procedure (TCLP) dilakukan untuk mengetahui kandungan logam berat pada abu insinerator. Pada campuran mix design Self Compacting Concrete (SCC) dilakukan 9 komposisi varian beton dengan matrix L9 metode taguchi. Variabel dalam penelitian ini adalah abu insinerator, faktor air semen dan dosis superplasticizer. Perbandingan semen dengan abu insinerator yaitu (semen : abu insinerator) 100% : 0% ; 90% : 10% (1) ; 85% : 15% (2) dan 80% : 20% (3). Kemudian pengaruh faktor air semen (FAS) sebesar 25% (1), 30% (2), 35% (3) dan superplasticizer : 0,6% (1) ; 0,7% (2) ; 0,8% (3) terhadap berat binder. Hasil penelitian menunjukkan kandungan Zn sebesar 203,1750 mg/l mengalami penurunan hingga 1,78 mg/l. Nilai kuat tekan optimum terdapat pada mix design T2 (A1F2S2) sebesar 47.73 MPa, T3 (A1F3S3) sebesar 42.03 MPa dan T5 (A2F2S3) sebesar 37.62 MPa di usia 28 hari. ==================================================================================================== Self Compacting Concrete (SCC) is an alternative concrete technology which is able to compact itself without any vibrating. This research uses waste incinerator ash from Dr. Soetomo Hospital Surabaya as cement replacement. Incinerator ash analysis were Scanning Electrone Microscope (SEM), X-Ray Diffraction (XRD), X-ray Fluorescence (XRF), Particle Size Analysis (PSA) and Toxicity Characteristic Leaching Procedure (TCLP). Toxicity Characteristic Leaching Procedure (TCLP) to determine concentration of heavy metals in waste incinerator ash. The research conducted 9 variating with matrix L9 Taguchi method. The variables of this research were incinerator ash, water to cement ratio and superplasticizer dosage. Cement to incinerator ash ratio (cement: incinerator ash) were 100% : 0%; 90% : 10% (1); 85% : 15% (2) and 80% : 20% (3). Water to cement ratio (w/c) were 25% (1), 30% (2), 35% (3) and superplasticizer were 0.6% (1), 0.7% (2); 0.8% (3) by weight binder. The result showed that incinerator ash can be used cement replacement. The highest compressive strength at 28 days of T2 (A1F2S2), T3 (A1F3S3), T5 (A2F2S3) was 47.73 M Pa, 42.03 MPa, and 37.62 MPa respectively. Zn concentration was found reduced from 203,1750 mg/l to 1,78 mg/l.
