- Estuary Porong is part of the east coast of Sidoarjo, East Java, which receives the Lapindo mudflow. Lapindo mudflow into the sea through the Porong river has caused sedimentation and changed the Porong river base substrate morphology so that it affects the organism that live in the estuary, especially macrozoobenthos because of their habitat on the bottom substrate. This study aims to identify the types of macrozoobenthos that live in the waters of Estuary Porong after the Lapindo mudflow. This research was conducted by observation method with sampling at 7 stations in Estuary Porong, Sidoarjo with purposive sampling method. Data collection was carried out at the end of the dry season using the Petersen grab sediment-taking tool. Identification of the types of macrozoobenthos is carried out in the Laboratory of Ecology, Department of Biology FMIPA Universitas Negeri Surabaya to species level. The research parameters measured included water quality, types of macrozoobenthos, Pb metal content in water and macrozoobenthos. Data were analyzed descriptively quantitative and qualitative. The results showed that in Porong estuary, 22 species of macrozoobenthos were found. The dominant and adaptive species to conditions covered by Lapindo mud are Potamocorbula faba, Chironomus sp., Varuna yui, and Mictyris platycheles. There is a relationship between Pb levels in water and Pb levels in macrozoobenthos
