Analysis and Identification of Non-Avifauna Diversity in the Reclamation Area of Limestone Mining at PT Semen Indonesia

Biodiversity is a fundamental pillar in maintaining ecosystem balance, particularly in post-mining areas that are vulnerable to degradation. This study aims to analyze non-avifauna diversity in the reclamation area of limestone mining at PT Semen Indonesia, Tuban Plant. The research employed an exploratory survey method with purposive sampling, conducted from February to May 2021 in six mining sites: three limestone sites (Temandang, Pongpongan, Sumberarum) and three clay sites (Sugihan, Tobo, Mliwang). Data were analyzed using the Shannon-Wiener diversity index (H’), Simpson’s dominance index (D), and evenness index (J). The results showed that the average H’ value across all sites ranged between 2.47–3.04, which falls under the “GOOD” category, indicating medium diversity. The D values approached 0.00, suggesting the absence of dominance by any particular species, while J values ranged from 0.90–0.97, reflecting normal environmental conditions with relatively even population distribution. These findings indicate that the non-avifauna community in the reclamation areas is stable and has not been significantly disturbed by mining activities. This study highlights the importance of sustainable reclamation practices in supporting ecosystem recovery and conserving non-avifauna biodiversity in industrial mining landscapes.
