Waduk Jatibarang merupakan bendungan yang menampung beberapa aliran sungai yang kemudian menjadi sarana dan prasarana akuatik dan mendukung kegiatan pariwisata yang ada. Masuknya air dari beberapa sungai ke dalam waduk dapat membawa bahan pencemar sehingga dapat mengakibatkan perairan waduk menjadi tercemar. Salah satu indikator penting dalam penentuan kualitas air adalah dengan melihat tingkat saprobitas di perairan.

Tujuan dari penelitian ini adalah untuk mengetahui tingkat saprobitas perairan Waduk Jatibarang. Penelitian ini dilaksanakan pada bulan Mei – Juni 2017. Penelitian ini menggunakan metode studi kasus dengan analisis deskriptif dan analisis korelasi, dengan mengukur parameter pendukung yaitu parameter fisika, kimia, indeks biologi, dan indeks saprobitas. Hasil pengamatan menunjukkan bahwa nilai kelimpahan fitoplankton berkisar antara 236-865 ind/l, indeks keanekaragaman berkisar antara 1.02-1.77 indeks keseragaman berkisar antara 0.58-0.85 dan indeks dominasi berkisar antara 0.14-0.96. Indeks Kualitas Air (IKA) yang didapatkan berkisar antara 51.74-55.06 sehingga kualitas perairan dalam kategori sedang. Berdasarkan hasil penelitian didapatkan bahwa nilai indeks saprobitas berkisar antara 0.60-2.75 dan nilai indeks tropik saprobik berkisar antara 2.02-4.06 sehingga dapat disimpulkan bahwa perairan Waduk Jatibarang termasuk dalam golongan β-mesosaprobik/ oligosaprobik atau tercemar ringan.
