Abstract

The purpose of this study is to determine the quality of concrete roof tile by using coconut coir fiber-added materials and sand reduction based on the percentage of fiber that is added to the thickness of the concrete tile ± 8 mm when viewed from the physical and mechanical properties. Study on concrete tile used method of testing conducted experiments in the Building Materials laboratory of Civil Engineering, Yogyakarta State University. While the process of manufacture and maintenance of concrete rooftile made in TB.Tri Harto. Mix designs using comparison 1pc: 2KP: 2.5 PS, with various additional coco fiber and sand reduction 0%, 2.5%, 5%, and 7.5%, with an analysis of data used is the calculation of average and referring to the SNI 0096 2007. Average yield testing of concrete roof tiles with various additional coco fiber and sand reduction 0%, 2.5%, 5%, and 7.5%, namely: (1) The nature seems for variation in fiber 0%, there is one concrete roof tile with a surface crack hair, fiber 2.5% variation there are no defects, variations in fiber 5%, there is one concrete roof tiles with surfaces are not smooth, and the variation of 7.5% fiber, there are two concrete tiles with surfaces are not smooth, the four variations are only on the variation of fiber 7.5% that do not meet quality requirements, (2) concrete tile has a maximum deviation of the size of the difference of the required size is 0.5 mm which is still acceptable quality, (3) concrete tile maximum flatness deviation is 1.133 mm and still meet quality requirements, (4) Characteristic bending loads for each fiber variation in sequence is N 1166.094, 1256.023 N, 1400 N, and 1489.357 N. But the characteristic bending loads are still less than required, (5) Absorption of water / porosity for each fiber in a sequence variation was 9.553%, 9.694%, 9.773% and 9.868%, the fourth variation of the addition of fiber is still acceptable quality; (6) Testing for resistance to water seepage (impermeability) showed that the concrete roof tile for all variations of fiber, resistant to water seepage and meet quality requirements; (7) Power absorption of heat to each fiber in a sequence variation was 67.251%, 63.743%, 65.497 %, and 63.158%; 8) On the whole the best results among the four variations of the addition of fiber is a concrete tile with a variety of coconut fibers and sand 7.5% reduction, but of the four variations are still not qualified SNI 0096 2007. Keywords: coco fiber, concrete roof-tile, fiber concrete roof-tile
