Abstract

Sungai Way Umpu berada di wilayah Kabupaten Way Kanan, Provinsi Lampung. Sungai ini memiliki lahan pada daerah aliran sungai yang dimanfaatkan oleh penduduk sekitar. Limbah buangan menuju sungai dihasilkan oleh lahan yang dapat menyebabkan peningkatan beban pencemaran melebihi kemampuan daya tampung sungai. Penelitian ini bertujuan untuk mengukur daya tampung beban pencemaran dan mengetahui parameter kualitas air yang melebihi baku mutu di Sungai Way Umpu. Penelitian dilakukan pada empat stasiun penelitian. Hasil pengukuran kualitas air dibandingkan dengan baku mutu kelas III sesuai Peraturan Daerah Provinsi Lampung no 11 tahun 2012. Metode neraca massa digunakan untuk menganalisis daya tampung pada titik tampung stasiun 4 (ST-4). Hasil penelitian menunjukkan kualitas air pada ST-3 untuk parameter BOD telah melebihi baku mutu. Sedangkan hasil analisis daya tampung pada titik tampung (ST-4) untuk parameter (nitrat, DO, BOD, dan total coliform) masih dalam standar kisaran baku mutu Kelas III, sehingga Sungai Way Umpu masih memiliki kemampuan menampung beban pencemaran dan dapat digunakan sesuai peruntukannya.

Abstract

Way Umpu River, located in Way Kanan Regency, Lampung Province, is widely used by the local community and the waste products are ultimately disposed of into the river. This can cause a decrease in river water quality which can cause changes in the balance of the ecosystem, both biotic and abiotic. One of the organisms that can be used as a bioindicator is macrozoobenthos. This research aims to determine the diversity of macrozoobenthos as a bioindicator of water pollution quality. The method used was a survey method and sampling using Ekmen Grab at 6 sampling stations. Samples were taken 3 times in the left, middle and right bank areas of the river. Apart from that, water analysis was carried out in the form of physical parameters (temperature and TSS) and chemical parameters (pH, DO, COD, BOD). The data was then analyzed using the Diversity Index. The research results found 14 types of macrozoobenthos consisting of 5 phylum, namely Arthopoda, Mollusca, Porifera, Ciliophora, and Annelida. From the results of the analysis of the macrozoobenthos diversity index at station IV, it has a value of 0.56 ind/m2, which states that the location is heavily polluted. Physical and chemical factors show a significant correlation with macrozoobenthos diversity.
