Abstract

Pemantauan kualitas air umumnya dilakukan melalui pengukuran parameter fisik-kimia, namun pendekatan tersebut belum sepenuhnya mampu menggambarkan dampak biologis pencemar terhadap organisme akuatik. Penelitian ini bertujuan mengevaluasi kualitas badan air di lingkungan Fakultas Sains dan Analitika Data (FSAD) Institut Teknologi Sepuluh Nopember (ITS) berdasarkan parameter fisik-kimia, Indeks Pencemaran (IP), serta uji toksisitas menggunakan *Daphnia magna* dan *Branchinella thailandensis*. Sampel air diambil dari Sungai Departemen Biologi serta kolam Departemen Fisika, Kimia, dan Matematika. Parameter yang dianalisis meliputi suhu, pH, dissolved oxygen (DO), biological oxygen demand (BOD), total suspended solids (TSS), nitrat (NO₃), dan fosfat (PO₄). Status kualitas air ditentukan menggunakan metode Indeks Pencemaran berdasarkan PP Nomor 22 Tahun 2021 Lampiran IV, sedangkan uji toksisitas dilakukan selama 72 jam melalui pengamatan mortalitas dan abnormalitas morfologi organisme uji. Hasil penelitian menunjukkan bahwa suhu, pH, TSS, dan nitrat memenuhi baku mutu, sedangkan DO, BOD, dan fosfat melebihi baku mutu pada seluruh lokasi. Berdasarkan Indeks Pencemaran, seluruh lokasi termasuk kategori cemar sedang hingga cemar berat menurut baku mutu kelas III, namun tergolong cemar ringan berdasarkan baku mutu kelas IV. Uji toksisitas menunjukkan peningkatan mortalitas dan berbagai abnormalitas morfologi pada kedua organisme uji, dengan *Branchinella thailandensis* memiliki sensitivitas yang lebih tinggi dibandingkan *Daphnia magna*. Munculnya abnormalitas morfologi mengindikasikan bahwa respons biologis organisme tidak hanya dipengaruhi oleh parameter fisik-kimia yang diukur, tetapi juga diduga oleh kontaminan lain yang terdapat dalam sampel air. Oleh karena itu, kombinasi analisis kualitas air dan bioassay memberikan evaluasi kualitas badan air yang lebih komprehensif dibandingkan penggunaan parameter fisik-kimia saja.

Water quality monitoring is generally conducted through physicochemical parameter measurements; however, this approach does not fully describe the biological impacts of pollutants on aquatic organisms. This study aims to evaluate the water quality of water bodies within the Faculty of Science and Data Analytics (FSAD), Institut Teknologi Sepuluh Nopember (ITS), based on physicochemical parameters, the Pollution Index (PI), and toxicity tests using *Daphnia magna* and *Branchinella thailandensis*. Water samples were collected from the river at the Department of Biology and from ponds at the Departments of Physics, Chemistry, and Mathematics. The parameters analyzed included temperature, pH, dissolved oxygen (DO), biological oxygen demand (BOD), total suspended solids (TSS), nitrate (NO₃), and phosphate (PO₄). Water quality status was determined using the Pollution Index method based on Government Regulation (PP) No. 22 of 2021, Appendix IV, while toxicity tests were conducted over 72 hours by observing mortality and morphological abnormalities in the test organisms. The results showed that temperature, pH, TSS, and nitrate met the applicable water quality standards, whereas DO, BOD, and phosphate exceeded the standards at all sampling sites. Based on the Pollution Index, all sites were classified as moderately to heavily polluted under Class III standards, but only lightly polluted under Class IV standards. The toxicity tests revealed increased mortality and various morphological abnormalities in both test organisms, with *Branchinella thailandensis* exhibiting greater sensitivity than *Daphnia magna*. The occurrence of these morphological abnormalities indicates that the biological responses of the organisms were influenced not only by the measured physicochemical parameters but also by other contaminants potentially present in the water samples. Therefore, combining physicochemical water quality analysis with bioassays provides a more comprehensive assessment of water body quality than relying solely on physicochemical parameters.
