dc.description.abstractFly Ash (Fly Ash) comes from the combustion of a boiler called Palm Oil Fuel Ash (POFA) which is pozzolanic which contains high silica (SiO2) and aluminum (Al2O3) and the main content is sand containing hydroxide. The method used in this research is mixing. This research was conducted with a ratio of 1 cement: 1 Foaming Agent: 1 sand and the addition of Fly Ash with a percentage (0%; 5%; 10% and 15%) to the reduction of the amount of sand which aims to characterize the addition of fly ash. Fly ash with Fourier Transform-Infra Spectroscopy (FTIR) and X-Ray Fluorescence (XRF) instruments, lightweight concrete products using X-Ray Fluorescence (XRF) and Scanning Electron Microscopy (SEM) instruments and analyzed the effect of adding solid waste based on the ratio optimal for the manufacture of lightweight brick concrete according to SNI 03-0349-1989. The results obtained based on the chemical composition test on fly ash solid waste and lightweight brick concrete products are that there are compounds that make up building construction, such as SiO2 and Al2O3 as fillers, CaO as adhesives and Fe2O3 as hardeners. The results of the functional group analysis showed that it was at a wave number of 873.79 cm-1 which was indicated by the presence of the Bending Si-O-Si functional group. Morphological analysis of lightweight brick products found that lightweight bricks have grain size, pore diameters are smaller and denser so that the lighter brick products formed are better and stronger. The effect of the addition of Fly Ash, based on the ratio of the addition of Fly Ash which is optimal for the manufacture of lightweight bricks is the addition of the percentage of BR 1 5% sample, namely the water absorption of lightweight bricks is 32.96% with SNI 03-0349-1989 absorption lightweight brick concrete maximum 25%, the volume weight obtained is 1294 kg/m2 with SNI 03-0349-1989 at least 800-1400 kg/m2 and the compressive strength of lightweight brick concrete obtained is 17.5 MPa with SNI 03-3449- 2002 the compressive strength of lightweight brick concrete is at least 6.89 Mpa.en_US
