This study enveloped an innovative uses of pineapple peel (PP) incorporated with
recycled aggregate concrete (RAC) from construction waste as an artificial concrete
reef for estuarine ecosystem. An artificial reef concrete composite will be made of
using PP reinforced RAC as a matrix. To determine the compressive strength of the
concrete composite, the PP is mix with RAC in 10%, 20% and 30% respectively. The
concrete cubes without PP use as control sample and test carried out for 28 days. The
total nutrient disperse determine using total nitrogen and phosphorus test of the water
samples in 6 days. The expected outcome show the total phosphorus and nitrate
increase as the percentage of PP use is increase. On the contrary, the compressive
strength indicated decreases with the increased of PP. As conclusion, pineapple peel
reinforced RAC is significant to be used as an artificial reef with some modifications
on mechanical properties.
