Sidoarjo waters is a buffer zone of Surabaya City. Sidoarjo has many industries such as the metal, textile and waste treatment industries. Many industrial wastes are discharged into Sidoarjo waters, especially Sedati. Waste entering the waters can affect water quality, which influences the living things. One of them is echinoderms. This research purpose to find out the differences of echinoderms in Sedati waters. The research was done from October to December 2019. The data obtained were analyzed descriptively quantitatively using the diversity index Shanon Winner and ANOVA. The results showed that the diversity of echinoderms species found has significant differences. Species were found like Archaster typicus, Echinothrix calamaris, and Ophiothrix sp. The average diversity of echinoderms was 0.4119 + 0.1479 (H < 1) so it was classified as low criteria with polluted water quality. The low variation of echinoderms can be caused by several factors such as location, season, physical quality, chemical quality, biotic factors and the fishing gear used. One of the efforts reduces the impact of pollution is to treat waste before it transferred to the release and move the fishing gear used to be more environmentally friendly.
