The utilization of gypsum board and fly ash waste as alternative materials in making bricks is one of the efforts to reduce the amount of industrial waste in the construction sector, namely gypsum board and fly ash waste. The use of gypsum board and fly ash waste cannot be separated from relatively large amount and the potential to pollute the environment. The pozzolanic properties contained in fly ash combined with gypsum board waste are expected to improve the quality of the bricks. The purpose of this study was to determine the value of the compressive strength of bricks. The method used is an experimental research method in which variations in the composition of gypsum board and fly ash waste are 0% and 0%, 5% and 25%, 7.5%, and 27.5%, and 10% and 30% of the weight, respectively. cement using a sample size of 37 x 10 x 15 cm. Based on the results of the study, it showed that the compressive strength test of the gypsum board and fly ash waste bricks had met the quality requirements according to SNI 03-0349-1989 with the average compressive strength value for each composition of 42.37 Kg/cm2, 73.04 Kg/cm2, 49.30 Kg/cm2, and 43.59 Kg/cm2. © Published under licence by IOP Publishing Ltd.
