Aktivitas yang berpotensi menjadi ancaman pencemaran di antaranya Penambangan Emas Tanpa Izin (PETI) dan industri pertambangan PT Antam yang berada di sekitar aliran Sungai Cikaniki. Logam berat pencemar di perairan Sungai Cikaniki terdiri dari timbal (Pb), kadmium (Cd), dan merkuri (Hg). Logam berat yang masuk ke badan air juga dapat terakumulasi di dalam tubuh ikan. Penelitian ini bertujuan untuk mengetahui kandungan logam berat timbal, kadmium, dan merkuri di dalam air Sungai Cikaniki dan tubuh ikan Wader (Barbodes binotatus) yang hidup di sungai tersebut. Pengambilan sampel dilakukan secara random purposive sampling di lima stasiun yang mewakili daerah aliran sungai bagian hulu, hilir, kawasan industri emas, area penambangan liar, dan kawasan irigasi. Penelitian dilakukan selama tiga bulan, dari bulan Januari hingga Maret 2020. Pengujian kadar logam berat dalam air dan tubuh ikan dilakukan dengan menggunakan ICP-OES (Inductively Coupled Plasma-Optical Emission Spectrometry). Hasil pengujian menunjukkan kandungan logam berat Pb dan Hg dalam air masih berada di bawah Nilai Ambang Batas (NAB) baku mutu menurut Peraturan Pemerintah Republik Indonesia No. 22 Tahun 2021 Lampiran VI, sedangkan kandungan Cd dalam air Sungai Cikaniki kurang dari 0,02 mg/L. Dalam tubuh ikan Wader, kandungan kadmium adalah < 0,4 mg/kg, sedangkan kandungan merkuri dan timbal telah melebihi nilai ambang batas dari baku mutu WHO tahun 1989. Akumulasi logam berat pada ikan dijumpai paling tinggi berasal dari daerah yang terdapat aktivitas penambangan emas. Analisis korelasi Pearson menunjukkan parameter lingkungan yang paling berpengaruh terhadap kandungan logam berat dalam air dan tubuh ikan adalah suhu air. Keberadaan logam berat di dalam air dan ikan di Sungai Cikaniki harus diwaspadai karena bersifat akumulatif di dalam tubuh manusia.

ABSTRAK Sungai Ciliwung telah ada dan menjadi bagian penting masyarakat sejak zaman purba. Namun seiring dengan berlalunya waktu dan perkembangan pesat, sejak tahun 2009 Sungai Ciliwung telah tercemar dari hulu. Salah satu polutan yang bisa menurunkan kualitas air sungai adalah fosfat. Keberadaan fosfat yang berlebihan di badan air dapat menyebabkan kondisi pengayaan nutrisi (eutrofikasi), dan dengan dukungan nitrat dapat menyebabkan algae blooming yang menjadi salah satu masalah lingkungan. Penelitian ini dilakukan untuk mengetahui dinamika senyawa fosfat Sungai Ciliwung apakah pencemarannya berkurang, sama, atau lebih buruk. Ruang lingkup penelitian meliputi pengambilan sampel air sungai pada tiga titik Katulampa, Pasar Bogor, dan Warung Jambu dengan interval waktu sampling 8 jam dalam sehari, dan dilakukan setiap minggu selama 3 minggu berturut-turut. Kemudian dilakukan analisis sampel di laboratorium, serta interpretasi data dengan membandingkan hasilnya terhadap PP No.82 tahun 2001. Nilai total fosfat di air sungai Ciliwung Hulu tidak memenuhi standar kualitas lingkungan PP. 82 tahun 2001, dan diindikasikan berada dalam kondisi eutrofikasi.
