The uses of recycled waste will not only reduce the environmental problem, but it will
also contribute to new innovations and technology. In this study, the leaching
behaviour of pumpkin peels incorporate in the artificial reef fabricate from recycle
aggregate concrete. Pumpkin peels are determine with the concrete as reinforcement
which enhance the mechanical properties and produce nutrients to attract fish habitat.
Material test is conduct on the concrete reef specimens to determine its compressive
strength. The dispersion of the nutrients are measure by using total phosphorus and
nitrate test of the water sample collect from each of the artificial reef. As conclusion,
pumpkin peel reinforce recycle aggregate concrete is significant to be used as artificial
reef for estuarine ecosystem with some modifications on mechanical properties.
