Riau Province is an area that has the largest peatland in Sumatra, namely 4.044 million ha (56.1% of the Sumatra peatland area or 45% of the land area of Riau Province). Peat soils have a low bearing capacity, a high degree of compressibility, and high water content. So peat is unfavorable to support building construction. Because it takes a foundation which is quite expensive so that a building can stand firmly to withstand the existing construction on it. Therefore it requires innovations in concrete. Concrete is a construction that is often used in infrastructure development. For peat areas, a light-weight concrete alternative is needed. This study aims to investigate the replacement of coarse aggregate (stone) with PET plastic by analyzing the concrete compressive test and the mass / weight of the concrete. Thus it can be seen which plastic mixture goes to lightweight concrete and is suitable for peatland construction. The benefit of this research is to create light concrete that can be used on peatlands. Replacement of coarse aggregate with PET plastic is made with various mixtures of 0%, 40%, 50%, 70%, and 100%. The results of the test mixture consisted of 70% and 100% light concrete, weighing 6.4 kg & 5.81 kg. In a 70% PET mixture, the quality of the K-193 concrete can be categorized as light concrete with medium strength so that it can be used in peatland construction.
