Abstract

This research was conducted to compare the use of alternative abrasive media for samboja sand to replace silica sand in the sand blasting process. The first stage in this research is XRD and Microscope Optics testing to determine the characteristics of the sand and the shape of the particles. In the sand blasting process, the test sample used is a plate with rush grade B. Then the plate sample was sand blasted with a pressure of 0.7 Mpa (7 bar), Sand blasting was carried out in stages based on the abrasive media to be used with variations in spraying time of 10, 15 and 20 seconds. The spraying distance used is 60 cm while the spraying angle is 45º. After the sand blasting process is carried out, the next step is visual observation to determine the level of cleanliness produced based on the ISO 8501-1 standard. Followed by roughness test based on ISO 4287 standard. The result is that samboja sand and silica have dominant characteristics, namely having a quartz phase and hexagonal crystal form, for the particle shape of samboja sand is sub rounded while silica sand is angular. Then obtained the same level of cleanliness based on ISO 8501-1, namely in samboja sand Sa 2.5 for a sand blasting time of 10 seconds, Sa 2.5 for a sand blasting time of 15 seconds and Sa 3 for a sand blasting time of 20 seconds. While the silica sand is Sa 2.5 for a sand blasting time of 10 seconds, Sa 2.5 for a sand blasting time of 15 seconds and Sa 3 for a sand blasting time of 20 seconds. It was also found that the roughness value of the sand blasting based on ISO 4287 standard was 5.978 m for sand blasting time of 10 seconds, 6.175 m for sand blasting time of 15 seconds and 7.206 m for sand blasting time of 20 seconds. The silica sand is 6.645 m for a sand blasting time of 10 seconds, 6.848 m for a sand blasting time of 15 seconds and 7.895 m for a sand blasting time of 20 seconds. The difference in the average roughness value is caused by differences in the shape of the sand type particles where silica sand has a higher average than Samboja sand. This is due to the shape of the angular particles capable of producing sharp sand blasting results. Keywords : ASTM A36, Pasir Samboja, Pasir Silika, Roughness Test, Sand Blasting
