Diversity of aquatic insects at the abandoned marble mining site in Leang Leang Village, Maros Regency, South Sulawesi, Indonesia

Abstract

Abstract The abandoned marble mining site in Leang Leang Village, Maros Regency, has been neglected since 2019. The area has since been filled with rainwater, forming a water body utilized by the surrounding community as a water reserve during the dry season. Marble mining generates waste in the form of marble dust that can pollute water bodies. Aquatic insects are organisms that can be used to determine water pollution levels. This research aims to assess the diversity of aquatic insects and evaluate water quality based on aquatic insect families as bioindicators. Aquatic insect samples collected were identified and analyzed. Diversity, richness, and water quality observations were conducted using the Shannon-Wiener index (H’) and Hilsenhoff Family Biotic Index (HFBI) methods. The aquatic insect diversity index at the abandoned marble mining site in Leang Leang recorded a value of 1.03 (moderate category). The richness index scored 0.52, categorizing it as low. Based on the HFBI classification, water quality at the abandoned marble mining site in Leang Leang falls under the very poor category.
