Abstract

Red bricks are the most easy material to locate and use practically any building. Besides being cheap, red bricks are also often used because of their easy and plentiful production processes in all parts of Indonesia. Brick use in both construction and non-construction or structure needs to be increased products produced, either by improving the quality of the red brick matality or additions to other materials.. Based on sni 15-2094-2000, red bricks are a rectangular prism material, solid or perforated with a hole volume ata maximum of hole volume at 15% and are used for constructing walls of buildings, which are made of clay with or without active material and burned ata certain temperature. The study was done using the RSM method of using soft prelims. The data processing produced 20 samples with six times the repetition in the center. The results of this study were the result of the highest impaction in experiments 14, 122.9 kj/m2, with a 8-day drying parameters, a temperature of 968.18oc with a 10-hour heat span and the lowest impact on experiment 12 was 47.6 k Kj /m2 with the long drying parameters of 8 days, places up to 800oc and a length of warming 3.27 hours this is due to the long drying and long warming. Based on shem's test, the exact difference in the form of breaking the value of the broken impak tests shows that the surface has become crystalline with perfect uniform. even though some of the parts are cracked, it is because the water contained less than the lower intake, which forms the crystals at least 50%, while in some areas there is a portation or hole in which the convergence is still incomplete.

Abstract

Composite materials are new types of engineering materials consisting of two or more materials whose properties of each material differ from each. Thisresearch is done to assess theinfluence of the volume fraction of pineapple leaf fibers on tensile strength, modulus elasticity and composite impact strength using polyester matrix BQTN 157 with hand lay-up method withresearchojek in the form of pineapple leaf fiber composite with a immersion time of 2 hours and with NaOH 5% with variations in fiber volume fraction of 15%, 20%,%, 25%.%. Thehighest tensile strength K is found in the volume fraction of 25% with a tensile test strength value of 84.4 Mpa and the lowest tensile test strength is at a volume fraction of 15% with a tensile test strength value of 58.7 Mpa.. As for the highest elasticity modulus value is at a volume fraction of 25% which is 17933 Mpa and the lowest tensile test strength is at a volume fraction of 15% with a tensile test strength value of 16400 Mpa.. And for the highest impact strength composite with pineapple leaf fiber is found at a volume fraction of 25% with an average impact power value of 163.2 Kj / mm2 and the lowest impact strength value is in the fiber fraction of 15% with an average impact power value of 63.9 Kj / mm2.

Abstract

The quality of the welding joint is important in welding. Welding current is one of the factors that affect the quality of the connection. This study aims to determine the effect of SMAW welding current on the impact strength and hardness of ST.37 steel. The variables used in this study are the current variations of 80 A, 100 A and 125 A. The method used is experimental. Based on the impact test data, the 80 A current variation obtained an average impact energy of 193.861 Joules, while the average impact value was 2.423 Joule/mm2. With a current variation of 100 A, the average impact energy is 203.918 Joules and the average impact value is 2.548 Joule/mm2. The current variation of 125 A obtained an impact energy of 203.918 Joules and an impact value of 2,469 Joule/mm2. The 80 A current variation has the lowest average impact value and the 100 A current variation has the highest average impact value. The results of the hardness test for current variations of 80 A, 100 A, 125 A, obtained the highest average hardness value occurs at a current variation of 80 A with a value of 51.00 , while the lowest average hardness value occurs at a current variation of 125 A with a value of 50.279 . Based on the research data, it can be concluded that the variation of the welding current affects the impact strength and hardness.
