Abstract

The objectives of this research were: (1) is there any difference between compressive strength the moduler column segment of tile fraction concrete with the moduler column segment of red brick fraction concrete (2) is there any difference between specific gravity the moduler column segment of tile fraction concrete with the moduler column segment of red brick fraction concrete (3) percentage of clay fulfilling of optimal quality moduler column segment. This research used the quantitative method experiment by compression test. Population used by  33 moduler column segment 150 mm x 150 mm x 300 mm with variation of the percentage of red brick fraction and tile fraction replacement 0%, 20%, 40%, 65%, 80%, 100%. Data Technique analyzes used was the equations mark with lines the regression with the level significance 1%. Conclusion from this research is: (1) There was difference between compressive strength the moduler column segment of tile fraction concrete with the moduler column segment of red brick fraction concrete. On the moduler column segment of tile fraction concrete with percentage of 40%, 60% compressive strength equal to 15.81 Mpa and 15.04 Mpa fulfill the structure standard and the moduler column segment of red brick fraction concrete with percentage of 40%, 60%  compressive strength equal to 8.92 Mpa, and 6.56 Mpa not fulfill the structure standard (2) There was difference between specific gravity the moduler column segment of tile fraction concrete with the moduler column segment of red brick fraction concrete at variation of percentage of 40% and 100%. (3) Optimal quality of moduler column segment of tile fraction concrete with  percentage of 40%, compressive strength 15.81 Mpa, specific gravity 2217.05 kg/ m³.

Abstract

 A method used to improve the hardness of aluminium alloy is by applying age hardening process. The process in age hardening were solution heat treatmen, quenching, and artificial aging. At phase of artificial aging can be conducted by some variation. The variation  able to influence the result from process of age hardening. The aim of the research was to analyze the effect of temperature and holding time artificial aging to hardness of alumunium alloy. The alumunium alloy used for the research was ASSAB Prodax. The method used in the research was experiment method. The independen variables were temperature artificial aging and holding time artificial aging. The dependent variable was hardness of alumunium alloy. Variation temperature of artificial aging at 1200C, 1500C, and 1800C. Variation holding time of artificial aging at 2 , 4, and 6 hours. Based of the statistic analysis with anava two way to the data gathered from the research, it can be stated that the temperature artificial aging at 1200C  and holding time artificial aging at 6 hours resulted in improving hardness (78,98 HRB).
