Abstract

Mangrove ecosystems play an important role in maintaining ecological balance and supporting the socio-economic life of communities. This study aims to identify the biodiversity of mangrove fauna and its role as a bioindicator of ecosystem health on the coast of Santen Island, Banyuwangi, using a descriptive qualitative approach through field observations, interviews, and documentation. The results of the study show that there are six main types of fauna found at the study site, namely mangrove crabs, Cere fish, Tembakul fish, shrimp, kijing shellfish, and brackish water crabs, as well as a mangrove ecosystem dominated by the Rhizophora mucronata species. The presence of these fauna indicates that the condition of the mangrove ecosystem is still relatively healthy. Environmental factors such as mud thickness, salinity levels, and mangrove vegetation density have a significant effect on fauna diversity. In addition, human activities such as tourism and domestic waste disposal have the potential to reduce the quality of the ecosystem. Overall, the results of this study confirm that mangrove fauna can be used as effective bioindicators to assess the ecological conditions of coastal areas. Therefore, community-based conservation efforts and the application of sustainable ecotourism concepts are needed to maintain ecological, economic, and social balance in the coastal area of Santen Island, Banyuwangi.

Abstract

The growth of laundry businesses has led to an increase in the volume of wastewater containing detergents, organic matter, suspended solids, and phosphates, posing a potential environmental pollution risk if discharged without treatment. This study aimed to analyze the effects of varying the thickness of filtration media—composed of silica sand, bagasse, and activated carbon—and varying operational times on the reduction of pH, COD, TSS, and phosphate levels in laundry wastewater. A PVC-based gravity-flow (down-flow) filtration reactor was operated using three media composition variations: activated carbon-dominant (P1), bagasse-dominant (P2), and silica sand-dominant (P3), with operational times of 30, 60, and 90 minutes. The results indicated that variation P1 achieved the highest COD reduction efficiency (36.98%), while variation P3 yielded the greatest TSS reduction (98.18%). The pH levels of all effluents met the quality standards established by East Java Governor Regulation No. 52 of 2014. However, COD levels failed to meet the threshold across all treatments, and phosphate levels increased due to leaching from the bagasse media. Multiple linear regression analysis revealed that filtration media thickness significantly influenced effluent pH and TSS, whereas operational time did not have a significant partial effect on any of the parameters. As this filtration system could not simultaneously meet all quality standards, further treatment is required to enhance its effectiveness.
