Plastic waste in Indonesia in 2020-2021 occupies the second largest position in terms of the amount of accumulated waste, namely 17.15% and 15.54% after the type of food waste. Plastic is difficult to degrade or is difficult to decompose in the soil. Plastic dumped into the sea is dangerous. In 2020, Physeter Macrocephalus (protected whale) was found to have died from ingesting plastic and not digesting it properly. Replacing/modifying materials is an alternative to help overcome waste environmental problems in the construction sector. Most of the research using waste is the manufacture of concrete with certain compressive strength criteria. As a form of support for green building, research utilizes plastic waste to replace some of the fine aggregate in the manufacture of paving blocks. This study reviewed the strength class of paving block Grade B or Min. 17 MPa, where fine aggregate is replaced by plastic waste up to 40%. Plastic waste is cleaned and cut into small pieces. The results showed that the replacement of fine aggregate with plastic waste up to 30% still produced Grade B or Min. 17 MPa.
