Aktivitas keramba jaring apung (KJA) dapat mengakibatkan penurunan kualitas air. Tujuan penelitian ini adalah menentukan dampak aktivitas KJA di Waduk Lahor terhadap perubahan Kualitas air berdasarkan beberapa paremeter fisika kimia dan indeks biotik dari Diatom sebagai bioindikator. Pengambilan sampel air dan Diatom dilakukan di muara Sungai Lahor (3 stasiun) merupakan inlet dari Waduk Lahor dan daerah sekitar bendungan (1 stasiun) menggunakan purposive random sampling berdasarkan aktivitas KJA dengan pengulangan pada masing-masing stasiun tiga kali. Pengambilan sampel Diatom dengan water sampler vertikal dan disaring menggunakan plankton net. Identifikasi dan perhitungan Diatom dengan Counting Chamber Sedgewick Rafter Cell dan buku identifikasi. Hasil identifikasi dan penghitungan Diatom digunakan untuk menentukan Trophic Diatom Index (TDI) dan Pollution Tolerant Value (% PTV). Karakter fisika kimia air (pH, kecerahan, turbiditas, DO dan BOD) diukur pada lokasi yang sama dengan pengambilan sampel Diatom. Hasil penelitian menunjukkan bahwa kualitas air terutama parameter BOD dan kecerahan di Waduk Lahor belum memenuhi standar untuk aktivitas perikanan. Aktivitas KJA di muara Sungai Lahor berdasarkan beberapa indek biotik dari Diatom telah berdampak pada penurunan kualitas air yaitu status nutrisi menjadi eutrofik sampai hiper-eutrofik (TDI) dan tingkat pencemaran bahan organik ringan sampai sedang (% PTV).References
