Instalasi Pengolahan Air Limbah (IPAL) berperan krusial dalam menjaga kualitas air tambak serta mengurangi potensi pencemaran yang timbul akibat kegiatan budidaya udang vaname (Litopenaeus vannamei) secara intensif. Penelitian ini bertujuan untuk mengevaluasi kinerja dan efektivitas sistem IPAL melalui pendekatan analisis Indeks Pencemaran (IP). Pengambilan sampel dilakukan dengan metode purposive sampling pada tiga titik pengamatan, yaitu saluran masuk (inlet), kolam IPAL, dan saluran keluar (outlet). Hasil analisis menunjukkan bahwa nilai IP pada saluran masuk berkisar antara 0,65–0,69 dan masih memenuhi baku mutu kualitas air. Nilai IP pada kolam IPAL meningkat menjadi 1,51–1,82, sedangkan pada saluran keluar berada pada kisaran 1,56–1,82, keduanya termasuk dalam kategori tercemar ringan. Peningkatan nilai IP di setiap tahapan menunjukkan bahwa proses pengolahan dalam IPAL belum bekerja secara optimal dalam menurunkan beban pencemar. Oleh karena itu, sistem IPAL masih memerlukan peningkatan efektivitas, terutama melalui perbaikan proses aerasi dan penerapan teknologi pengolahan lanjutan. Upaya ini diharapkan dapat meningkatkan efisiensi pengolahan limbah, sehingga air buangan menjadi lebih aman dan mendukung keberlanjutan budidaya udang di wilayah Leupung, Aceh Besar.

Wastewater Treatment Plants (WWTPs) play a crucial role in maintaining pond water quality and reducing the potential for pollution arising from intensive whiteleg shrimp (Litopenaeus vannamei) cultivation. This study aims to evaluate the performance and effectiveness of the WWTP system through a Pollution Index (IP) analysis approach. Sampling was conducted using a purposive sampling method at three observation points: the inlet, the WWTP pond, and the outlet. The analysis results show that the IP value at the inlet ranges from 0.65–0.69 and still meets water quality standards. The IP value at the WWTP pond increases to 1.51–1.82, while at the outlet it ranges from 1.56–1.82, both of which are categorized as lightly polluted. The increase in IP values ​​at each stage indicates that the WWTP treatment process has not been working optimally in reducing the pollutant load. Therefore, the WWTP system still requires increased effectiveness, especially through improvements in the aeration process and the application of advanced treatment technologies. This effort is expected to increase the efficiency of waste processing, so that wastewater becomes safer and supports the sustainability of shrimp farming in the Leupung area, Aceh Besar.
