Industrial waste is a by-product of industrial processes from waste material or building material. The study was conducted to analyze the used of solid waste pulp dreg and grits through chemical characterization to make bricks. In brick formation, the CaO content is very important because it functions as an adhesive and from its characterization shows the CaO content is 58.10% in dregs and 59.76% in grits. From the research method carried out by mixing dreg and slaker grit waste with other materials, the best results were obtained at the maximum value of the compressive strength of quality I brick is 7 Mpa (SNI; 3.5 Mpa). Characterization of material used Scanning Electron Microscope (SEM), X-Ray Fluorescence (XRF) and IR Prestige-21 instruments to analyze the chemical content of the waste. Universal Testing Machine (UTM) was used for compressive strength analysis using material strength when given a load with certain pressure. The result showed that the best which for bricks that lower water absorption and bricks that have large compressive strength value 7 Mpa. [ABSTRACT FROM AUTHOR]
